摘要
火力发电厂辅机系统中的温度保护经常因为温度测量值的跳变而发生误动。介绍了一种在温度保护逻辑中应用慢信号保护模块及时发现温度测量值跳变故障的方法,提高了机组运行的稳定性、可靠性和经济性。
The temperature protection＇s incorrect trip in auxiliary equipment system of the thermal power plant often happens for the sudden changing of the temperature measurement value. This article introduced a way to find the trouble- spot of the temperature - measuring by using the SAIPro function. This increased the stability, reliability and economy of the thermal power plant significantly.
