Analysis and Suggestions on Pole 2 Strip Caused by No Check Back Signal from Y3 Valve of GGII Baoan Station
are used in Guizhou-Guangdong ±500 kV HVDC II power transmission lines.To ensure safe and reliable operation
thyristor voltage mornitors(TVM) are used to have on-line mornitoring on each thyristor.By light cables
TVM sends real-time feedback signal to VBE
whose single-chip can judge the default of thyristor valves by reading such check back signals.When the number of default thyristors exceeds the number of thyristor redundancy
trip signal is sent.The author analyzes the default and provides the related suggestions on Pole 2 trip caused by no check back signal from Y3 valve of GGII Baoan station
