| Abstract: | At the initial stage of the operation of the Qinghai-Tibet DC system,the voltage waveform distortion of the terminal screen measuring device of the Qaidam converter substation caused frequent UVY and UVD faults in the pole protection system,resulting in disturbance to the stability of the DC system of the converter-side bushing.Through the research on the modification of the voltage measuring device at the end of the converter casing of the Qaidam converter substation,the safety hazard of the voltage measuring device of the other end of the converter is eliminated,and the stable operation of the Qinghai-Tibet DC network system is ensured. |
