同有目的的正常开机不同,本文所讨论的“异常开机”是在没有开机要求的情况下的机组自行起动的开机现象。在水电站运行中,绝对不允许出现在没有开机要求的情况下水轮机由停机状态突然起动的异常开机事件。本文将叙述一起异常开机事件并分析起因及处理办法。 无论是正常开机还是异常开机,水轮机之所以能够从停机状态起动是因为水轮机导水机构在调速器的控制下能够打开。在这里应首先强调一点:调速器在自动方式下运行是本文进行事件分析
Different from the purpose of normal boot, the “abnormal boot” discussed in this article is the boot of the unit when it is not powered on. During the operation of the hydropower station, it is absolutely not allowed to have an abnormal power-on event when the turbine suddenly starts from a shutdown state without a power-on requirement. This article will describe an unusual boot event and analyze the causes and solutions. Whether the machine is booted normally or abnormally, the reason why the turbine can be started from the shutdown state is that the turbine guide mechanism can be opened under the control of the governor. Here it should be emphasized at the outset: governor operation in automatic mode is the event analysis of this article
