摘要
对楚穗直流孤岛方式下的各种故障后系统的稳定性进行了计算分析,指出了主要存在的稳定问题。分别针对孤岛方式下线路胪2故障、楚穗直流极或阀组闭锁以及直流保护引起楚穗直流功率突降等情况进行了具体研究分析,提出了相应的安全稳定控制策略。
The stability of islanded system after various faults under Chuxiong Suidong UHVDC islanded operation situation is analyzed, and the main stability question is pointed out. The situation of line N-2 faults, pole or valve group block of Chuxiong-Suidong UHVDC and DC power drop by DC protection are analyzed in detail, corresponding security and stability control strategy is pointed out.
