摘要
介绍了PLC在水电厂泄水闸门控制系统中的应用。为了提高系统的安全性 ,采用了电动操作断路器对闸门的动力电源进行控制。闸位计采用绝对值格雷码编码器以及弹性平衡传感器组成。通过实际运行表明 ,本系统操作使用方便 ,性能稳定可靠 ,自动化程度较高。
The application of the PLC in the automation system of sluices,which are in the hydroelectric plant is introduced.In order to improve the security of the system, the breakers are operated to control the power of the sluices in the dynamoelectric method and the gate level gauge is composed of absolute Gray coder and elastic equilibrium sensor. Through the practical run, the system is operated conveniently, which has steady and reliable performance, and has a high degree of automation.
