因存在未预料到的异步自励磁( asynchronous self-excitation, ASE)问题,托克托电厂为抑制次同步谐振( subsyn-chronous resonance, SSR)而安装的阻塞滤波器( blocking filter, BF)无法投入运行。为对BF进行适当的优化调整,使其发挥抑制SSR的作用,分析了托克托电厂采用 BF预防机网复合共振( torsional interaction, TI)和暂态扭矩放大( torque amplification, TA)以及引发ASE的原理,提出了将ASE和TI及TA分别采用异步机和同步机模型与参数进行研究及BF优化设计的思路和方法。通过特征根计算和仿真相互验证了BF优化设计方案。对优化后BF的性能进行了全面评估,采取了相应的保护措施,并对BF与其他保护措施进行了协调和调整；成功解决了托克托电厂各类次同步谐振问题。结果表明,成功的SSR解决方案需全面评估ASE、 TI和TA三种形式的SSR风险,并全部妥善解决。

Due to the unanticipated asynchronous self-excitation ( ASE) problem, the blocking filter ( BF) installed to suppress the subsynchronous resonance ( SSR) in Tuoketuo power plant can not be put into operation. Therefore it is necessary to optimize and ad-just the BF appropriately to ensure it work well to inhitit SSR. In response to the need, this paper analyzes the theory of preventing tor-sional interaction ( TI) , transient torque amplification ( TA) and triggering the ASE by blocking filter, and proposes the ideas and methods of optimal design of blocking filter and studying ASE and TI ( TA) respectively by applying models and parameters of asyn-chronous and synchronous machines. Through eigen-value analysis and simulation program, the proposed optimization scheme of bloc-king filter is mutually validated. The performance of the optimized BF is assessed comprehensively, and based on which the corre-sponding protection measures are applied, coordination and adjustments to BF and other protective measures are performed. So far all kinds of SSR problems in Tuoketuo power plant are solved successfully. The results show that the success of SSR solutions require a comprehensively assessment and proper solution of the risk of three types of SSR—ASE, TI and TA.
