The Siemens holistic smart metering solution presented for the first time in Barcelona provides a future-oriented basis for upcoming smart grid applications, for example for allowing and handling the increased feed-in of renewables-based power. The holistic solution enables operations including remote meter reading and management of all meters in a specific supply area. Gas and water meters communicate bi-directionally with Siemens’ smart AMIS electricity meters. Existing ripple-control systems can also to be replaced with the new technology. In addition, the system can acquire network parameters such as overvoltage and undervoltage, short-term and long-term failures, and power quality indicators from the medium-voltage network and end customers. On the basis of detailed information such as earth-fault and short-circuit indications, and measurable asset indicators, it is also possible to optimize overall grid operation.
The special features include the integration of gas and water meters, the telecontrol equipment of the AMIS data conncentrators for transformer stations and the integration in an existing Scada system (supervisory control and data acquisition). At Metering Europe in Barcelona presentations will be given to show how Siemens integrates the Energy IP meter data management system into a corporate IT landscape as part of a holistic smart metering-solution via an SAP MDUS (meter data unification and synchronization) interface. It enables the flow of information and command transfer between SAP and the meter data management system.
The basis for this integration is a service-oriented architecture, which exchanges measured data, alarms and control data bi-directionally between SAP, the AMIS system and third-party systems, such as load management, outage management and job orders. The meter data management system serves as the neural hub of the intelligent metering infrastructure. This data and process integration enables utilities to optimize their business processes in the office and their customer support. “With this holistic smart metering solution, which we will present in Barcelona, AMIS and the meter data management system complement each other outstandingly. All the requirements made on an integrated solution for meter data acquisition and processing, and distribution network automation in the future are thus fulfilled. Worldwide we are one of the few companies with the requisite know-how and technology that are capable of offering one-stop solutions,“ said Ralf Christian, CEO of the Power Distribution Division of Siemens Energy.
Energy-efficient, eco-friendly solutions for setting up smart grids are part of the Siemens environmental portfolio with which the company earned revenues of nearly EUR19 billion in fiscal 2008, That is, equivalent to about a quarter of Siemens’ total revenue and makes Siemens the world’s leading provider of eco-friendly technology.
The Siemens Energy Sector is the world’s leading supplier of a complete spectrum of products, services and solutions for the generation, transmission and distribution of power and for the extraction, conversion and transport of oil and gas. In fiscal 2008 (ended September 30), the Energy Sector had revenues of approximately EUR22.6 billion and received new orders totaling approximately EUR33.4 billion and posted a profit of EUR1.4 billion. On September 30, 2008, the Energy Sector had a work force of approximately 83,500. Further information is available at:ww1.energy.siemens.com/energy/en/
