Research on Substation Power Module Monitoring System Based on Computer Communication
The reliability of substation power module directly affects the safe and stable operation of power system.This paper designs a monitoring system of substation power module based on computer communication,including three core modules:data acquisition,communication transmission and abnormal alarm.The system uses Advanced Reduced Instruction Set Computer Machines(ARM)embedded technology and multi-sensor fusion technology to achieve high-precision data acquisition,uses the hybrid scheme of industrial Ethernet and 4G wireless communication to ensure the reliability of data transmission,and builds an anomaly detection model based on statistical learning and time series analysis.Through the experimental verification,the results show that the system is significantly superior to the traditional manual inspection in data acquisition accuracy,communication success rate,fault detection rate and other aspects,which provides an effective solution for improving the monitoring efficiency and reliability of the substation power module.
