Smart grid solution with a scalable power quality measurement system<\/h2>\n

Due to the increasing changes in electrical grids<\/a>, load flow information is becoming more and more important. For you as a distribution network operator, increasingly also in combination with power quality data. As a distribution network operator, you are increasingly complaining that the relevant information at grid level 7<\/a> is either not available at all or is inadequate. Without a proper smart grid solution, this would be equivalent to “flying blind.” Intelligent metering systems (smart meters) won’t help you with this either. This is because, among other things, these are only suitable to a limited extent (e.g. due to data protection rules, insufficient measurement performance for network management, etc.).<\/p>\n

One of the great challenges is that the formerly centralized electrical energy world is developing into a highly dynamic as well as very complex decentralized system. In this context, it must be possible to systemically process new but relevant information in a targeted handling of data.<\/p>\n<\/div><\/section>\n

ewz on the way to the smart grid<\/h2>\n

The “Elektrizit\u00e4tswerk der Stadt Z\u00fcrich” (Electricity company of the city of Zurich) has been responsible for the supply of electricity in Zurich since its foundation in 1892. As an institute under public law, the EWZ is organizationally subordinate to the Department of Industrial Operations as a service department. At the same time, ewz is also very well networked internationally.<\/p>\n

Read here<\/a> a media release how ewz has set out to roll out a fully comprehensive and digitalized smart grid solution. Companies such as smart grid solutions AG with its complete approach, Venios with its Venios Energy platform and Camille Bauer Metrawatt AG with the latest and scalable measuring technology of the LINAX\u00ae PQ5000CL series provide support.<\/p>\n

Excursus: What does Smart Grid mean<\/h3>\n

A smart grid is an electrical system that intelligently ensures the exchange of electrical energy from various sources with consumers of different demand characteristics by incorporating measurement and mostly digital information and communication technologies. Such a system should take into account the needs of all market players and society. The use and operation of the system can thus be optimized and made more efficient, costs and environmental impact can be minimized, and the quality and security of supply can be guaranteed to a sufficiently high degree.<\/p>\n

Effects of a smart grid on measurement technology<\/h5>\n

Basically, the common measurement data of voltage, current and frequency as well as their derived quantities are still required. However, and here comes the possible challenge for the smart grid application: The metering data will be combined and related to new customer needs (e.g., scalability, real-time, connection to existing control systems, integration into new platform solutions, connectivity, distinct technical consulting needs, cyber security, additional costs, etc.). Thus, the traditional IEC groupings of electrical instrumentation will possibly change and overlap even more. In addition, it certainly makes sense to continue to use analog indicators (electro-mechanical) redundantly for essential functions. These will withstand any failure and\/or attack of a data communication. This is also very clear from the matrix shown above.<\/p>\n
