Addressing Critical Needs in the Electricity Industry

The electricity industry continues to undergo fundamental changes, which are shaping how engineering work is performed and energy services are provided. Low load growth, over-capacity, and future market uncertainty are creating pressures on the availability of capital and the reduction of operating costs to address issues of aging infrastructure. As electrical utilities are looking to replace and refurbish assets, the need to perform effective condition assessment, risk management activities, and strategic asset management planning arises.

These concerns are amplified by an increasing loss of internal technical expertise. As senior engineers retire and new engineers are brought in, the need to retain institutional memory and provide training guidance becomes ever more critical.

As electrical utilities are forced to upgrade and replace their aging infrastructure, many experience challenges in keeping pace with the flood of emerging technologies entering the market. It is both time consuming and capital intensive to find, test, and evaluate these technologies, but choosing the wrong one can lead to performance and financial consequences.

Finally, considering high energy demands along with increasing pressure to reduce greenhouse gas emissions and mitigate the effects of extreme weather events, the electric utility sector is faced with the unique challenge of providing energy services which are both cleaner and more reliable. Advancements in sustainability for all will require innovative approaches and rethinking business as usual.

This project provides a guide on the topic of forensic analysis of component failures, through the use of Root Cause Failure Analysis. It identifies the most effective and appropriate asset intelligence data sets to be used during forensic analysis of equipment failures. The guide recommends effective data collection, recording and storage techniques to make this information readily available when required, providing a helpful tool to assist with the collection and analysis of appropriate asset intelligence for root cause failure analysis.

Asset Intelligence for Root Cause Failure Analysis

Transmission Line Asset ManagementGroup OverviewThe objective of this program is to bring together transmission system operators to exchange information on asset management practices and techniques and to facilitate collaboration that will optimize the management of overhead transmission line assets. Key focus areas of the group include asset life extension in order to defer the need for major capital expenditures, the refinement and development of prudent and effective asset management practices, and the maintenance techniques needed to reduce life cycle cost and to maintain performance of the transmission lines system.

The Transmission Line Asset Management, Transmission Overhead Line Design & Extreme Mitigation, and the Power System Planning & Operations groups hosted an international industry open conference in Tucson, Arizona. The purpose of the conference was to bring together industry experts on the topics of reliability, security, restoration, and safety, to have them provide insight on how these issues interrelate, and what can be done to improve system performance. In addition to the main assembly, attendees are invited to attend break-out sessions based on their interests, thus providing participants with a focused platform to exchange knowledge and information on new initiatives and recent technological advancements.

2018 Highlighted ProjectsUsing Inspection Data to Establish Appropriate Inspection Cycles for Transmission LinesA significant amount of information is acquired in aerial or ground based visual inspection of overhead transmission lines. This work identifies relationships between the level of risk and inspection frequencies on the basis of condition and defect data collected during inspections. This information will then be used to identify the potential for increasing or decreasing inspection intervals to maintain or improve risk management practices for transmission line assets.

Transmission Line Infrared Inspection GuideInfrared inspections are used to identify anomalies and confirm electrical integrity of transmission lines. The project provides a guide for the effective use of infrared technology. The project identifies overheated transmission line components on heavily loaded lines and those with minimal loading. The guide provides methods to identify damaged polymer and porcelain insulators.

Managing Transmission Line Safety and Reliability Risks through InspectionTransmission line owners regularly inspect their lines to assess deteriorating condition over time and mitigate risks on the system due to component failures, vehicle accidents, clearance encroachments, and other disturbances in the Right-of-Way. This report quantifies possible the reasons for inspecting transmission lines. Where that is not possible, the report provides insight in a qualitative format. Granularity will include individual inspection activities, several inspection programs determining the effectiveness of the inspections as well as inspection programs relative to the objectives.

Risk Management Practices for Transmission Lines As utilities move away from traditional asset manage-ment practices it has become increasingly prevalent that risk management is an essential element in any asset management strategy. This project examines risk management specific for lines that includes risk iden-tification, risk analysis in terms of consequences and their probabilities, and risk evaluation. This will include links to different derivations for condition and critical-ity to determine the likelihood of failure and provides line of sight to industry practices.

Post Transmission Line Failure Data Collection and AnalysisFailures of overhead transmission line (OHTL) facilities occur for a variety of reasons and when they do there is much to be learned. The project develops a state-of-the-art report providing guidance on the collection and analysis of information and materials to support OHTL failure investigations. The scope will develop data requirements, and failure resource (e.g., data and materials such as component samples). It will collect and develop guidelines to support failure investiga-tions and asset management improvements. Finally, the project will identify material and component con-dition and quality assessment procedures including laboratory inspection and testing procedures.

Development of Fragility Models and Line Exposures to Extreme EventsReliability of a line is defined as the probability that the line will perform its intended function under specified conditions for a specified period, normally defined as the service life. The primary focus is that the fragility model be GIS based. The report develops a clear methodology in addressing the vulnerability of the transmission system to an extreme event such as (Wind storm, Wind and Ice event, Downbursts, HIW etc.) and to identify the most vulnerable “hot spot” within the system.

Vibration of Transmission StructuresOverhead lines are in constant motion and often, these motions cause various types of damages to line components if the motion is not controlled. The project prepares a state of the art report for basic understanding of the vibration of lattice steel towers and tubular pole structures and its arm components. Additionally, the project focuses on various ways to mitigate the vibration issues in a practical manner.

Minimum Separation Between Underground Pipelines and Utility Grounding SystemsThis project provides an assessment tool for the determination of safe separation distance between high-voltage power line tower/pole footings and underground pipelines. This tool addresses arcing distance, while also considering corrosion of tower footings and grounding conductors, punctures of pipeline coatings due to faults, flashover damage to pipeline isolation flanges. The tool also addresses possible hazard step/touch potentials to pipeline and utility personnel.

Precision Assessment of Power Line Response to LightningUsing equipment and data currently available, there is a significant opportunity to better understand and improve the performance of transmission (TX) and distribution (DX) systems in response to direct and indirect lightning strikes. Observations from this report improves the geolocation of faults on T&D lines, in addition to providing detailed information about both fault-events and non-fault transients. Utility case studies are included to further validate and demonstrate these concepts.

Step and Touch Coordination during Substation Expansion.Well-designed substation grounding provides adequate safety and reliability to workers. However construction activities when stations are expanded can make step and touch coordination difficult to achieve. This project studies various construction activities and hazards during such work; and summarizes existing practices. It explores a wide range of barriers and procedures that could reduce step and touch potentials; performs analysis to quantify the efficiency and hazard reduction offered by differing mitigation methods; and provides recommendations to improve step and touch coordination during substation expansion.

2018 Highlighted ProjectsReal-Time Thermal Rating Systems for Underground Cable SystemsAn application guide was commissioned by member utilities interested in practices for implementing real-time thermal ratings on underground transmission cables, consisting of extruded, self-contained fluid-filled and pipe-type systems. This report summarizes the results of an industry survey of TUC members and non-utility members, and describes the characteristics, application considerations, and summary of suppliers of these systems. The results show that real-time thermal ratings have been applied for many utilities. However, it is important to understand the utility’s responsibilities when implementing these systems since only a portion of the work may be done by outside contractors due to utility knowhow and security.

Grounding and Bonding in Underground Cable Maintenance WorkPersonnel repairing HV cables are subject to step and touch potentials arising from load and fault currents on parallel circuits. Also, faults at terminating stations can be transferred along cables under repair where no parallel circuit is present. This report reviews the performance of existing grounding and bonding procedures for HPFF, SCFF, LPFF, and XLPE cable types, comparing the performance of bare versus insulated ground continuity conductors, and reviewing the benefits and drawbacks of isolating sheaths and phases at terminating stations versus bonding them to ground. It recommends improved work practices and provides engineering guidelines to designers who specify cable configurations.

Infrastructure Protection & SecurityGroup OverviewThe Infrastructure Protection and Security Interest Group (IPSIG) is an international technical and utility-only forum for utility personnel tasked with physical and cyber security of generation, transmission, and distribution assets. The group activities aim to enhance the design, evaluation, and functioning of security programs and operations through member-driven exchange of information, intelligence, and lessons learned. This collaboration supports the development of best practices and facilitates inter-utility benchmarking that enable members to better understand and improve their security posture.

Cyber Security: Program activities aim to evaluate cybersecurity standards and frameworks for communication and control networks, risk management, and regulatory compliance.Physical Security: Program activities aim to enhance the design and functioning of security operations for dams and powerhouses, substations, transmission/distribution assets, and RoWs.

Physical Security Maturity MatrixThe Physical Security Maturity Matrix (PSMM) identifies the key attributes that should be addressed in order to create and maintain an effective physical security program within an electric utility. The PSMM enables utilities to perform self-evaluations in order to identify weaknesses and gaps. Through subsequent meetings of PSMM users, participants can then benchmark their security programs against others in the industry. Together, these metrics help IPSIG members communicate the overall – and relative – strength of their security programs to upper management, and to help justify expenditures that will improve their security posture.

2018 Highlighted ProjectKey ManagementThis project identifies the key management approaches currently being employed by IPSIG members and develops recommendations for “best practices” that can be applied to the full range of access control needs of electric utilities. Emphasis is placed on the integration of all tools (physical and cyber) to effectively manage access control, which includes key fobs, cascading locks, and double authentication (depending on security needs).

Wood Pole Refurbishment Technologies - Technology WatchWood poles represent a significant asset for most utilities. Damage and deterioration at the ground line and the pole top can result in significant loss of strength and failure of the pole. If the pole can be refurbished, then the service life can be extended and the probability of failure reduced. This project reviewed utility practices, evaluated the cost effectiveness of the current wood pole refurbishment technologies, and provide insight into potential future pole refurbishment technologies.

Impact on Worker Safety of Distributed Energy Resources Connected to the Distribution GridDistributed Energy Resources are being installed at an accelerated rate and concerns are rising from field crews on the management of the new technology. Multiple sources of energy that are not directly controlled by the utility and power from unusual sources are among the new concerns. Utility safety policy includes a robust approach to worker safety that considers many eventualities, but an aversion to new risks means that practical solutions are often by-passed in favour of more absolute measures. This report will act as a guideline to cost effective safety practices.

Topics & Issues

Cryptocurrency Server FarmsCryptocurrency server farms are one of many new and emerging loads expected to have large-scale penetration on the public supply network. Understanding the loading and power quality impacts of such loads will assist utility engineers to design their systems adequately to better serve these customers and maintain power quality for all. Understanding the potential power quality challenges which exist inside these server farms will allow utility engineers to conduct efficient power quality investigations as needed, and to provide guidance for designing robust facilities able to withstand many of the normal and uncontrollable power system events.

Digital Waveform CharacterizationMany electric utilities have various types of monitors on their power networks (distribution and transmission) which record voltage and current waveforms. While waveform sampling and triggering methods may vary extensively between equipment, one commonality amongst utilities is that there is an increasing abundance of waveform data available for analysis. The project provides a technical report detailing numerous discreet signal algorithms which can be used to characterize voltage and current waveforms. Where possible, examples are provided which clearly demonstrate how the algorithms are applied using a sample set of discreet values.

2019 Highlighted ProjectsResponse of Small Scale PV Inverters to Power System EventsLaboratory testing will be performed on a number of common PV inverters in order to understand their response to power system events including over/under voltage and over/under frequency. The project determines how small scale grid-tied PV inverters will behave during power system events. It includes a substantial review of the currently available literature and standards relevant to the fault ride through capabilities and settings of small scale grid-tied inverter systems.

Control of Weeds in Electrical Facilities such as Substations, Switchyards, Capacitor Stations, and Cable Termination SitesTwo herbicide programs were developed in this project: one that utilizes products available in Canada, and one for the United States. These programs are designed to reduce the development of resistance and include strategies to reduce reliance on herbicides, such as preventative measures and non-herbicide techniques. The study included a literature review and a survey of electric and gas utilities to discover current vegetation management practices, particularly of bare-ground or rocked surface weed control. The results were analyzed to identify deficiencies, opportunities for improvement, best management practices, and future recommendations.

Vegetation Management Cost Benefit of Herbicide UseSpecies of trees within electric utility’s ROWs have the potential to conflict with overhead electric utility lines and are incompatible with the intended land use. Electric utilities throughout North America maintaining vegetation with the ROW by controlling the growth of incompatible species. The project conducted a comparison of the cost of maintaining vegetation on electric transmission right of way (ROW) corridors with and without the use of herbicides. Three case studies were used to compare the cost of Integrated Vegetation Management which includes the use of herbicides to control incompatible trees to simply maintaining ROW vegetation by repeated cutting without the use herbicides. Least cost economic analysis methods were used to determine the present value cost of each vegetation maintenance prescription over a 20-year evaluation period.

Mountain caribou are found in Alberta and British Columbia. Both species extend their ranges into Alaska. Woodland caribou are listed as threatened by the Species at Risk Act (SARA). The project will specifically help justify the selection and, conversely, the avoidance of various mitigation techniques and management practices that are generally accepted industry practices in caribou habitat, providing advice that is applicable to not only those managing boreal forest regions but other species-specific habitats across North America.

Migrating Distribution Vegetation Management Work Orders to Align with Spatial Data Inspection and work cycles in a vegetation management program are typically dictated by feeders or circuits from a database system, which can result in redundant visits to an asset, overcomplication of work systems, and inconsistencies across the program. This live case study based project investigates the benefits of transitioning from a traditional circuit/ feeder-based organization for managing Vegetation Management cycle to a spatial (area-based) approach to managing Vegetation Management cycles to produce a quantitative report that demonstrates the resulting cost savings.

An Analysis of PhoDAR vs LiDAR for Collecting Spatial Data by Electrical Utilities and Operational Recommendations for UseIn recent years, the use of LiDAR and PhoDAR has become common for collecting line profile, data structural configuration as well as corridor surveys. It also includes line management of clearances and vegetation growth and identification of any clearance violation under a specific weather condition. This project develops a practical guide for managers at electrical utilities that can be used to decide whether PhoDAR or LiDAR is the best method to use to collect information on vegetation, equipment and assets in a specific situation.

2019 Group Initiative Topics

Technical AdvisorDavid Curtis has been working in the electric utility industry for over thirty-seven years primarily for Ontario Hydro and Hydro One. He has international experience in Asset Management including Corporate Strategy Development, Risk Management, and Asset Planning.

Training Webinar: Monetizing Risk for Planning and Informing ExecutivesA key aspect to formulating and prioritizing asset management plans is recognizing and addressing risks to the utility. Understanding these risks and expressing them in a monetized form is often a challenge. Expressing risk in a monetized form can be important in the effective communication to executives in the utility. This webinar encourages informal sharing approaches used in their utilities.

Workshop: Whole Life Cycle Cost Model including economic End-of-LifeA Economically optimized investment planning for electric utility assets should be done spanning the entire life. Due to the different ways of planning, the end of life phase is often a challenging area of the life cycle to model on an economic basis. This workshop will explore the different approaches to whole life cycle cost modelling including the economic end of life phase.

Workshop: Decision Criteria for making investment decisions (risk, value, how these are defined)A core requirement for effective asset management plan development is a consistent set of criteria for making investment decisions. These criteria must stem from considerations

of utility risk and value to the utility. At this workshop, utilities will share how these decision criteria are defined and what lessons have been learned in their formulation.

Working Group: Developing a shared library of KPI’sMeasuring the success of asset management plans typically requires reporting against a set of Key Performance Indicators (KPI’s). Over the years, electric utilities have developed numerous KPI’s of varying usefulness. This working group will develop a library of KPI’s including their characteristics.
