NI Grid Automation System

ni.com/gridautomation

Lower the Cost of Grid Information

The Grid Automation System is a customizable intelligent electronic device designed to

simplify substation monitoring and upgrades while improving measurement visibility. This

approach to grid instrumentation uses a common set of hardware with software-designed

measurements and communication protocols. With this approach, the Grid Automation

System can deliver new measurements to operators and power system engineers while

integrating with existing systems. Additionally, the software-based measurements can be

upgraded in the future as standards, research, and needs evolve.

Get a Better Picture of Your Changing Electrical Network

Renewable generation, energy storage, plug-in electric vehicles, interconnects, and

increasing demand are just some of the challenges grid owners face today. These

challenges require increased flexibility and new measurement technology to improve grid

control and asset use. The Grid Automation System helps utility companies and utility

suppliers with the intelligent grid information they need now and in the future as new

problems emerge.

Get Better Information

Decisions from the control room that rely on information gathered from the grid are

limited by the capabilities of deployed instrumentation. With the Grid Automation System,

capabilities can change as the needs of the grid change. Full access to the streaming

waveform data is available for inline processing, online monitoring, and storage on the

device. You can program the Grid Automation System to intelligently select which data to

monitor, store, or transmit to reduce storage and bandwidth requirements. The analog

input channels that are designed for potential transformer and current transformer inputs

use high-speed, high-resolution converters that sample at up to 1,000 samples per cycle

with 24 bits of resolution. The quality of this system goes beyond the specifications

because NI has nearly 40 years of experience in measurement instrumentation.

Get the measurements you want with a customizable, software designed instrument.

Simplify Your Upgrade Plan

Using a hybrid, customizable device like the Grid Automation System can help simplify the

transition between technologies by bridging your existing setup with new technology and

minimizing the need for excess equipment. For example, the Grid Automation System

programmed as a remote terminal unit can collect data from slave devices communicating

over one protocol and output to the SCADA/EMS system over another. This prevents

upgrading more equipment than needed and allows power engineers to selectively

replace systems that are legacy or outdated.

Solve Your Problems

You can use the Grid Automation System as a ready-to-run device with a default

personality, a ready-to-program “clean slate,” or anything in between. This is possible

because of the open approach to software. NI applications feature code that is freely

available for modification with a current version of LabVIEW and the LabVIEW Electrical

Power Suite installed on a development machine. If you need a ready-to-run personality

without the development, NI and NI Alliance Partners deliver turnkey solutions designed

to contract specifications. Contact NI today to learn more about these solutions.

NI Technology in Action

National Grid UK Improves Operational Data

National Grid UK, the transmission system operator for nearly 20 million people in the UK,

is deploying an advanced, upgradable grid measurement system to provide better

operational data for the state of the UK grid. With the challenges of today and the

unforeseen challenges of the future, National Grid UK is focusing on developing a flexible

solution that can be upgraded with new software as the measurement needs of the grid

and amount of data available evolve.

National Grid UK built a solution using CompactRIO to manage data visibility issues now and in the future.

The Solution

National Grid UK selected the NI platform to develop a flexible, powerful, and connected

measurement system capable of gathering and analyzing large amounts of data to better

detect grid-wide trends. Compared to its existing infrastructure, implementing a smarter,

more connected system allows National Grid UK to manage change, optimize energy

sources, and plan for the future grid. The new system also takes advantage of the high-

processing power of CompactRIO to offer grid-wide visibility while providing more in-

depth data then the previous system.

LocalGrid Increases Reliability & Security with MicroGrids

LocalGrid Technologies, a spin-off of National Instruments Alliance Partner Prolucid

Technologies Inc., along with National Instruments, is leading the development of “smart”

distributed power generation and MicroGrids. Changing to a decentralized approach to

power management enables distributed generation by making renewable energy available

that is either utility or state owned, or available through feed-in-tariff (FIT) programs.

Toronto Hydro-Electric System Limited (Toronto Hydro) has been a participant in this

project. Toronto Hydro is one of the largest municipal electricity distribution companies in

Canada and has approximately 1,600 feeder lines and 719,000 customers, according to

their website. Making the most effective use of multiple generation sources requires a

dynamic and flexible distribution grid. This is a key driver for grid modernization. Toronto

Hydro hopes to use intelligent monitoring and control to help overcome many restrictions,

and the Intelligent Node Project with LocalGrid is their first effort in this important area.

“We standardized our design on the CompactRIO platform because it is a highly modular off-the-shelf, software-designed controller that provides us the I/O and processing flexibility we need.”

-Bob Leigh, CEO LocalGrid Technologies

The Solution

Using the NI cRIO-9068 controller and LocalGrid DataFabric software built on the NI

LabVIEW platform, utilities and power providers can now quickly and cost-effectively

deploy MicroGrid solutions that are modular and standards based so they can be

easily customized for future growth and expansion. This solution enables secure and high-

resolution communications over existing and low-bandwidth networks seamlessly, and

can be used to manage distributed grid assets, develop better network “stress” insight,

and optimize generation dispatch.
