Research and Application of GOOSE in Digital Pumped Storage Power Stations

With the rapid development of power systems, digital technology is becoming increasingly important in distributed energy management and dispatching. The implementation of IEC 61850 and its sub-standard IEC 61850–410 provides a solid theoretical foundation for the construction of intelligent pumped-storage power stations in China. This paper first introduces the basic concepts of the IEC 61850 standard and discusses in depth the protocol stack and message encoding format of the GOOSE communication protocol. In response to the specific construction needs of pumped-storage power stations, NARI Group has developed a variety of intelligent electronic devices (IEDs) that support the IEC 61850 protocol and proposed specific solutions for the intelligentization of field equipment. Through GOOSE communication, information exchange and coordinated control between IEDs are realized, thereby improving the operating efficiency and intelligent level of pumped-storage power stations.
