Intelligent Judgment Method of the Measurement and Control Device Crash of Transmission Line Based on SCADA

In order to check the measurement and control device crash of transmission line in time, an intelligent discrimination method is proposed. This method makes full use of the data storage and data processing functions of SCADA. According to the actual work experience of power grid monitoring and the characteristics of the measured data after the measurement and control device crash, the intelligent judgment process and criterion conditions for quickly identifying the measurement and control device crash are established, which greatly improves the troubleshooting efficiency of the monitoring and control device crash. Taking the actual power grid as an example, the test results show that the method can reliably and quickly identify the measurement and control device crash of transmission line.
