摘要
介绍了水轮发电机组一级保护的配置与动作过程,对一次过速存在的问题进行了分析。提出了一级过速保护的技术改造方案,改造方案实施后,一级过速保护机组从未出现过误动作的现象。
The configuration and the action process of the primary protection of the water turbine-generator set were introduced.The problems existed in primary overspeed protection were analyzed.The technical reformation scheme of the primary overspeed protection was put forward.After the reformation scheme was implemented,the faulty action of the primary overspeed protection no longer occurred.
