摘要
详细介绍了可编程逻辑控制器(PLC)在水电厂负荷控制中的应用,从系统的组成开始分析了系统的整体功能及系统的设计过程。通过对控制过程及实现过程的分析,以逻辑图的方式展示了PLC控制程序对上网负荷控制的清晰流程。试验结果表明,系统可以轻松地完成全厂的功率调节,实现对上网负荷的控制。
The application of PLC to the load control in hydropower plants is described in detail. The construction, the integrated functions and the design process of the system are analyzed. Based on the analysis of the control process and realization process, a clear flow for the online load control by the PLC control program is illustrated. The test results indicate that the system can adjust the power of the whole station easily, and realize online load control.
