摘要
为实现应急电站的快速反应及自动控制,采用FP1系列PLC实现应急电站的自动控制方法,做到当主电网失电时,迅速启动应急电站,并调整频率,向外供电。在供电过程中,循环检测转速的大小,并相应地进行加减速控制,当主电网恢复供电时,停止应急电站,重新由主电网供电。对启动失败、转速过大、电压过大或过小、油压过低、水温过高等进行故障诊断、报警及保护。
A method of autocontroling the Emergency Electrical Station (EES) by PLC is presented.The system can detect main power lost and start EES automatically,adjust the frequency,give alarm or shutdown EES when system at fault.When the main system resumes,EES will cease and deliver the task to the main system as before.
