Metering

General

The Metering Division provides support forenergy supply utilities, with particular em-phasis on network and account manage-ment.Energy meters are used for measuring theconsumption of electricity, gas, heat andwater for purposes of billing. In this regard,modern energy meters should be able tohandle differing regional tariff structures aswell as complex tariffs in industrial applica-tions.Siemens makes a decisive contributionto the increased competitiveness of theircustomers, leading to tangible improve-ments in the control of energy flows, in theacquisition and processing of meter data,in meter management and in customercommunications. Siemens Metering sup-plies integrated solutions, from energymetering to billing. From a single meterto a complete billing system.We supply tailored solutions for marketsectors as diverse as production, transport,industry, services, retail and residential.

Examples:

Making energy pay

After metering, the data is collected, the billis sent, and finally, the receipt of paymentis recorded. Siemens Metering Division im-proves efficiency by optimizing businessprocesses.

Protecting investment

The compatibility of the products and sys-tems provides for subsequent functionalenhancements. Their functionality can beadapted to emerging requirements at anytime. Take DLMS (DLMS Device LanguageMessage Specification), for example:Siemens co-developed this new commonstandard which will be the meter readingprotocol of the future.

Environmental certification

Siemens supplemented the quality man-agement system with an environmentalmanagement system. Siemens Meteringhas ISO 14001 certification.

Electricity meters

Introduction

For the last hundred years Siemens andLandis & Gyr have been producing high-quality electricity meters. In 1971 we werethe first manufacturer in the world to pro-duce solid-state meters, securing our posi-tion as market leader in this field as well.The latest generation of meters sets newstandards in economy and efficiency.E.g. the Dialog range is already equippedto communicate with the equipment andsystems of other manufacturers.

Area of Applications

The meters supports all applicable stand-ards worldwide and practically all applica-tions in the field of energy measurement.Fig. 7 provides an general overview aboutelectricity meters and their applications.They are used for residential, commercial,industrial, transmission and generation(grid metering) applications.

Requirements

Accurate measuring on its own is notenough. A forward-looking meter mustbe equipped for future modifications andenhancements. Meter reading is anothermajor area where energy supply processescan be considerably simplified. Here, too,Siemens offer specific solutions for reduc-ing operating costs.

Gas and heat meters

Gas meters for gas suppliers

Adaptive gas meters measure with a highdegree of accuracy, their sturdy, modulardesign makes them expandable and pro-tects them against external interferenceand manipulation. They can be fitted any-where and without any wear parts.Each meter is built to provide a servicelife of around 20 years. Whatever happens,adaptive gas meters will be able to copewith even the most drastic changes. Theintegrated EN 61107 interface provides fortrouble-free data exchange, and the LCDdisplay provides for quick reading.The meters are fully compatible with pre-payment systems.

Adaptive Domestic Gas Meters

■ High accuracy■ Future proof■ With integral valve

Heat meters

The type ULTRAHEAT 2WR4 will providemany years of accurate and reliable service.Even small quantities can be metered andbilled with precision. Flow rates are meas-ured via a wear-free ultrasonic technologywith no moving parts. This patented systemmeans that the meter will operate reliably,regardless of flow profile, installation con-ditions and water temperature(Fig. 10 and 11).The meters are approved for use through-out Europe and fulfill the forthcoming CENrequirements by complying with EN 1434.They are system-integration ready thanksto communication units. The meters canbe upgraded at any time during service.The complete meter range offers the rightsolution for any application (Fig. 10).

Demand Side Mangement withRipple Control Systems

Applications

Ripple control allows a electricity supplyutility from control center to remotely con-trol certain consumers on the supply net-work. Consumers with energy storing ca-pabilities, such as room heating systems,hot water storage systems, air conditioningsystems or pumping stations, are particu-larly suitable for load control purposes.

Operation and background

Audio frequency pulses, which can be en-coded for all necessary switching commands,are transmitted via radio or the available lowand high voltage lines. More than 3700 ripplecontrol systems and 6 billions receiversare daily in use for several decades, at thefacilities of more than 1000 customers inapprox. 20 countries.

Components

The components of a ripple control systeminclude (Fig. 12):■ command units in the control center,

which issues the switching commandsand provides for operating parameterselection and control.

■ transmitters, which generate the audiofrequency pulses and coupling deviceswhich feed the signals into the network.

■ receivers to decode the ripple controlsignals in the distribution network.

Customer value

The installation of a ripple control systempays off especially quickly in the area ofload management by minimizing the costsof generation, import and distribution ofthe energy that is supplied to customers.It allows investments in energy supplyfacilities to be drastically reduced. Around7–30% of the investment required to gen-erate one megawatt of energy will producean equivalent energy saving if invested inripple control.Ripple control provides a major help fornetwork operators in observing their con-tracts with energy producers in the dereg-ulated market (optimization of load curves,observation of energy import schedules,improved utilization of supply networks).

Radio frequency ripple control

A joint venture between four major utilitiesin Germany was founded to provide radiofrequency ripple control as a service, mak-ing the advantages of ripple control availa-ble to utilities without their own transmit-ters. A central computer system and twolong-wave transmitters broadcasts custom-er signals and, at regular intervals, the exacttime and date. The transmitters and centralcomputer system operate redundantly andare controlled by the utilities via DATEX-P.

Energy Data Acquisition (EDA)

Managing the energy data

To improve logistics and accounts in a de-regulate environment energy data acquisi-tion and processing is used in energy datamanagement system.The careful utilization of energy requiresmeticulous acquisition of all relevant data –and then proper interpretation. Siemenstelemetering systems help people in allsectors of energy supply and industry toutilize the available energy sparingly andselectively.

High demands on technology

Metering points form the interface betweenthe individual market players. Measuringaccuracy and long-term durability are takenfor granted. Logging of load profiles createsthe necessary clarity. Depending on thefield of application, whether in the high ormedium voltage range or in industry, differ-ent technologies are required and qualityfeatures are becoming increasingly signifi-cant.The use of cheap communication channelsplaces high demands on communicationsystems. High transfer rates, multiple pro-tocol capability and compatibility with a va-riety of media are a must. The data simplyhas to be made available for billing and eval-uation as quickly as possible.

Keeping one step ahead

Energy Data Acquisition Systems performcomplex tasks, and central stations calcu-late a wide range of values. Whether forbilling, statistics, network planning or tariffanalysis, Siemens EDA systems are availa-ble as single-user or client-server solutions.They are compatible with the equipment ofall leading manufacturers and are ready tomeet the challenges of the future.
