Abstract: |
The 220 kV Wushan digital substation is introduced. It applies the indoor GIS,the breakers with hydraulic spring mechanism and the digital protection & monitoring devices. In 220 kV system,the integra-ted electronic current and voltage transformer based on the Roche coil principle and the capacitor divided voltage principle is adopted; the IEC60044-8 protocol is applied for the data communication between MU (Merging Unit) and bay-level device; the optical fiber serial port is used for the data transmission ... |
