【摘要】 四川-华中电网联网后,为了提高四川电网运行的安全稳定性,有效地防治灾难性事故的发生,进行了四川电网灾变防治策略的研究。在现有电网结构的基础上,应用先进的非线性励磁和非线性鲁棒调速控制技术提高发电厂的安全稳定水平。同时研究中采用了柔性交流输电技术与非线性控制技术结合,来改善和提高四川电网的动态品质和安全稳定性。还对四川电网的规划提出了合理化建议,以便合理分配电网潮流。通过计算机仿真,证明了提出的控制策略能明显改善四川电网的安全稳定水平,增强电网的抗扰动能力,真正起到灾变防治的作用。更多还原

【Abstract】 Security and stability have become major problems confronting the Sichuan Power Grid since it was connected to the Central China Power Grid.To improve the security and stability as well as to effectively prevent collapses in the Sichuan Power Grid,the use of advanced nonlinear control technology is recommended in this paper to improve power plant stability.FACTS technologies are used to enhance the dynamic performance and stability of the Sichuan Power Grid.Proposals for power grid planning are also presented to allocate the power flow more rationally.Systematic control strategies are developed to prevent collapse,with their effectiveness shown in computer simulations.更多还原
