小型水电站紧急关机过程中的破坏事故较多,如何优化紧急关机过程,保护机组和输水管道的安全,是小型水电站需要解决的一个问题。现将湖南省新宁县老虎坝电站研制的应用于小型水电站的水电站微电脑量测调整综合控制器中紧急关机部分的内容简介如下,以利于进一步研究探讨。(一) 优化依据从引起紧急关机的事例看,大多数紧急关机是由输电设备短路、系统甩掉大量负荷后而引起的。事故 In the process of emergency shutdown of small hydropower stations, there are more accidents. How to optimize the emergency shutdown process and protect the safety of generating units and water pipelines is a problem to be solved by small hydropower stations. At present, Hunan Province, Hunan Province, the development of the Laohu Dam Station used in small hydropower station microcomputer measurement and control integrated controller emergency shutdown part of the content is as follows, in order to facilitate further study. (A) Optimization Basis From the case of causing an emergency shutdown, most emergency shutdown is caused by the short circuit of power transmission equipment, the system after a lot of load shedding.
