电网黑启动中发电机自励磁仿真研究

摘要

With the development of power system, the harm of large area blackout is becoming more and more hazardous. The self-excitation of black-start power is one of the key factors of the black-start scheme, which highlights the importance of the study of self-excitation. This article analyzed the self-excitation’s generating principle and engineering criterion and simulated the self-excitation model by PSCAD. Finally, a practical example was used to demonstrate and put forward the settlement.%　　随着电力系统的发展壮大，大面积停电的危害也越来越大，所以必须对黑启动进行仿真校验研究。黑启动电源的自励磁现象也是黑启动的关键因素之一，由此凸显出自励磁研究的重要性。本文通过对自励磁产生的原理和工程判据进行分析，并运用 PSCAD 软件进行自励磁仿真建模，最后运用实际算例进行论证，并提出了解决方案。
