T/CSEE 0171-2020 Automatic high-frequency exclusion of generator sets in power system technology regulations
Basic Information
Scope
Main technical content: This standard specifies the basic requirements and configuration principles for the automatic high-frequency disconnection of generator sets in power systems, the setting methods for parameters, and the coordinated configuration principles between the automatic high-frequency disconnection of generator sets and the generator set's high-frequency protection and overspeed protection. This standard is applicable to high-frequency risk control in large power grids and to high-frequency risk control in isolated power grids disconnected from the main grid after an accident. Small-scale isolated power grids with the problem of "large generators and small grids" after a fault, and enterprise power grids with self-sufficient power plants can refer to and implement this standard accordingly.
