摘要：
The prediction and mitigation of commutation failure are influenced by the accuracy of extinguishing angle during fault transient period. In order to reduce the calculation error of extinction angle during fault transient period, the calculation formula of extinction angle including DC current variation is deduced by analyzing the commutation process of inverters. A method to improve the prediction accuracy of DC current variation during commutation is proposed. A commutation failure prediction criterion based on DC current differential is proposed. The conventional predictive extinction angle controller is optimized to ameliorate its control effect during fault transient period by adding DC current prediction module. Based on PSCAD/EMTDC simulation platform, a DC standard test model is built to simulate and analyze under the grounding faults of different transition resistors and inductors, which validates the effectiveness of the predictive commutation failure method and control strategy. © 2019, Power System Technology Press.
