火电厂保安电源柴油发电机组电气系统改造

The Electric Control System Reforming of the Diesel Generator Set for Emergency Power Supply in Thermal Power Plant

火力发电厂保安电源是保护重要设备的关键部件,柴油发电机组是保证大型火电厂在发生用电系统失电时能够安全停机和快速恢复供电的必备设备。以西门子可编程控制器(PLC)作为控制核心,结合一种新型柴油发电机组,对火电厂保安电源的自动化控制系统进行了优化,结果表明,有效提高了保安应急电源的响应速度,平均成功自启动时间减少10s,对研究大型火电厂安全生产及自动化的人员有一定的参考价值。

The emergency power supply of thermal power plant is a key component of protecting critical equipment,and diesel generator set is to ensure that large-scale thermal power plant in the event of loss of electrical power systems can safely shut down and the necessary equipment for rapid restoration of power supply.The research congcentrates on the control of the electric control system reforming of a new diesel generator sets in thermal power plant that makes use of Programmable Logic Controller technology.Results show that the response speed of the emergency power supply is improved effectively,successfully reduced the average time since the start 10s.This article could be some reference value to the researchers of safety and automation in large thermal power plant.
