Research On The Design And Application Of Hangzhou 110kV Intelligent Substation

With advances in technology, economic development, social growing demand for energy, power grid operating environment is becoming increasingly complex. Turn of the century, people that made the concept of smart grid, smart substation for the realization of the smart grid is very important effect. Substation comes from the common development, and then experienced the digital substation intelligent substation development process.Intelligent Substation is the use of advanced, reliable, integrated, low-carbon, environmentally smart devices to IEC61850 communication specification, based on the intelligent substation technology into station level, bay level and process level, the whole point of a hierarchical distributed design, intelligent electrical equipment interoperability and information sharing. Functional integration of its construction, maintenance status, information digitization, compact substation, to the development of intelligent substation requirements. Intelligent Substation specific direction include:the integration of hardware, software components, information management memory, a standard fusion, distributed power protection control. This in-depth analysis of the technical features and intelligent substation and key technologies, namely electronic transformer, intelligent primary equipment, on-line monitoring techniques and IEC61850 standards. Hangzhou 110kV substation construction thesis project, for example, launched the smart substation design. Designed around a selection of start and secondary equipment, and its station level, the process layer, a spacer layer to achieve a detailed description of the substation communication network design focus expanded.Accompanied by social, technological development, the development of intelligent substation trend is irreversible.
