Quantum PLC在水电厂现地控制层中的应用

With the development of computer technology and electron technology, the performance is more comprehensive and the system is more stable and more reliable for Monitoring System in Hydropower Plants. For good cost performance, Schneider PLC is used more and more in Monitoring System in Hydropower Plants, which makes less people to work on the Monitoring System or even no people to work on it come true. This paper first analyzes the development of automatic monitoring system local control units in our country's Hydropower Plants, and then dwells on the hardware constitution and the working principle of Quantum PLC, especially focuses on the application for Quantum PLC in Hydropower Plants, finally proves Quantum PLC could satisfy the request of spot's actual application, achieve the expected goals and bring great benefit to the Hydropower Plants by the successful operation of the improved control system.
