The traditional detection system based on SCADA system is interfered by channel,which leads to low precision of detection. In order to solve this problem,an automatic detection system based on dynamic correlation analysis for power grid alarm correlation is designed. According to the alarm dynamic correlation analysis model,deploy the overall design scheme of the system. The hardware structure of the system is designed with dual CPU combined with digital signal processor(DSP)and embedded processor(ARM). The C8051 F040 single chip microcomputer is used as the core module of the upper computer,and the alarm information is generated by the EKL-4 panel type fault alarm indicator. Using alarm correlation detection circuit to determine power network fault Equipment By capturing the signal characteristics of fault position mode and processing the noise reduction of the system according to the analytical model,the fault location can be accurately located,thus the system design can be completed.The experimental results show that the automatic detection accuracy of the system is high,which ensures the safe and stable operation of the power network.
