Research on Dual-Machine Real-Time Monitoring and Maintenance Scheme of RTU

At present, most RTU of the power plants adopt redundant configuration, host–standby switching mode in our country. Because of the two RTUs actually running in the virtual machine, the dispatching side cannot master the working state of the other machine in real time, which can have a great impact on the dispatcher in the actual operation. In this paper, a dual-machine real-time monitoring and maintenance scheme is proposed, which can not only guarantee the dual-machine monitoring of the plant and the station but also timely detect the plane failure of the dispatching data network. Then, the correctness and reliability of the monitoring information are improved effectively.
