摘要
以扫描周期方式运行的PLC ,难以对电站并车过程中的频差、相位等瞬变信号作出及时的响应。应用PLC高速处理功能 ,配置必要的硬件电路和模块化程序设计方法 ,解决了PLC对瞬变信号的响应问题 。
The PLC runs in the way of scanning period ,so it is difficult to respond to the instantaneous signals of the frequency and the phase in the power plant synchronizing. By applying the high speed processing function of PLC to power plant synchronizing and with the necessary hardware circuits and modularizing programs,the above mentioned problem is solved and the automation synchronizing of the power plant is realized.
