摘要
以瀑布沟大型水轮发电机为对象,在详细分析其可能发生的各种内部短路故障的基础上,采用基于转子每极双阻尼条的内部故障简化暂态仿真模型,对发电机中性点侧不同分支组合方式下各种主保护方案的动作情况进行了详细分析,确定了瀑布沟发电机优化主保护配置方案,为相关工程应用和研究工作提供了参考。
With the Pubugou huge hydraulic generator as an example, this paper analyzes all the faults that may occur in the stator. By employing the simplified transient simulation model of the internal fault based on dual-damper-under-each-pole, the protection results of different protection theories of different stator branch connection types on the neutral side are analyzed, and the optimized main protection scheme for the Pubugou generator is proposed, providing reference for relevant engineering application and research work.
