【摘要】 本文主要研究了四川-华中电网联网后互联系统所存在的问题以及防治灾难性事故的策略。针对四川-华中电网联网后四川电网所存在的问题,分析了发生灾难事故的根源。同时为了提高四川电网运行的安全稳定性,有效防治灾难性事故的发生,我们将在现有电网结构的基础上,全面分析和深入研究,应用先进的非线性控制技术及灵活交流输电技术对四川电网动态品质和稳定性进行改善,同时对四川电网的规划提出合理化建议,从而提出一套行之有效的灾变防治的控制策略。更多还原

【Abstract】 This paper has studied the operation problems of the Sichuan Power Grid when it was connected with Middle China Power Grid.According to those problems,the causation to the collapse has also been studied.In order to improve the power system’s stability and prevent the collapse,the nonlinear control theory and the FACTS devices has been applied into the Sichuan Power Grid.Those collapse prevention theory can enhance the power system’s dynamic performance and voltage stability.And the rational suggestions have been brought to the power system planning.Thus the whole Sichuan collapse prevention control strategy has been set up in this paper.更多还原
