Development of a blocking logic checking apparatus for substation measurement and control devices
1 Wenzhou Power Supply Company of SGCC, 325000 Zhejiang Wenzhou, China
After transforming substation measurement and control devices, the traditional method of blocking logic check needs to go back and forth among the measurement and control devices, and repeatedly connect a large number of wires, which lead to tedious operation and low efficiency. This paper developed a logic verification device based on 4G wireless communication, which used the Modbus/TCP transport protocol to access Ethernet, to complete the real-time data communication with the mobile control terminal. And this paper made a request to the logic controller according to practicality and cost. And the terminal software interface was designed by the orthogonal experimental design idea. The development of this device provided a new and efficient method for logic verification.
