为了解决某电厂保安段电源切换过程中柴油发电机容量不足导致汽轮机润滑油泵无法启动的问题,分析了柴油发电机启动后保安段需要自启动的主要设备及容量大小,针对设备的容量及启停时机采取有效措施,在确保机组安全的工况下,采取有效措施,选择大容量设备合适的启停时机,从而满足柴油发电机的容量,使能够自启动的设备正常运行,从而保障机组安全停机.
In order to solve the problem of insufficient diesel generator capacity during power supply switching in the security section of a power plant,which caused the turbine lubricating oil pump to be unable to start,it analyses the main equipment and capacity that need to be self-started in the security section after the diesel generator has been activated,and takes effective measures according to the capacity of the equipment and the timing of starting and stopping,so as to ensure the safety of the unit,take effective measures to select the right time to start and stop the large capacity equipment,so as to meet the capacity of the diesel generator,so that the equipment can be self-starting normal operation,so as to ensure the safe shutdown of the unit.
