摘要
针对余热发电机易失步运行的情况,提出了一种根据功角变化趋势的新的余热发电机失步保护方案。通过对失步运行原因的分析,论述了新方案失步保护策略的理论基础、功角的测量及实现方法。新方案改变了传统失步保护的观念,提高了余热发电机运行的可靠性。
In waste heat generator operation out of step is common. A new out-of-step protection scheme was proposed. Through analyzing the causes of asynchronous operation, the new scheme discussed the out-of-step protection strategy on the basis of theory, power angle measurement and implementation method. The new seheme has changed the traditional concept of out of step protection, and improved the running reliability of waste heat generator.
