Abstract:

As the important technical foundation of intelligent hydropower plants, the IEC 61850 standard presents the principles of the fundamental structure of the communication system of intelligent hydropower plants. Because of the universality and simplicity of the standard, the specifications of IEC 61850 for the communication mode and protocols applied to the automation system of hydropower plants are too general and the standard fails to make clear explanation of the specifications, which affects the application of the standard in intelligent hydropower plants. The distributed communication mode, typical communication network, communication protocol system and communication configuration of intelligent hydropower plant are analyzed so as to promote the use of IEC 61850 in hydropower plants. 
