Abstract
Commutation failure is one of the very frequent dynamic events in HVDC transmission systems. Most of the commutation failures are caused by the voltage disturbances of AC grid. Aiming at several commutation failure events occurred in China Southern Power Grid (CSG), April to August 2012, and based on the TFR and PMU waves of DC inverter station, and analyzing the changes of AC bus voltage and active power of DC lines during the events, this paper obtains the relevant laws of commutation failure in CSG’s HVDC systems, and proposes a practical criterion for commutation failure occurred in electromechanical transient simulation based on lower voltage sag. According to the criterion, the impact of the line faults occurred in the 50 substations of 500 kV in Guangdong on the DC commutation failure and system stability is evaluated.关键词
