Design of Universal Board Testing System for DC Transmission Control and Protection Platform

A universal board testing system was designed to address the issues of incomplete detection functions and difficulty in iterative upgrading of the existing DC transmission control and protection platform board testing system. The effectiveness and universality of the system were demonstrated through examples. The overall design plan., software and hardware design principles., universality principles., and testing plan of the system were emphasized. The testing process is simple and feasible., reducing the learning cost of on-site testing personnel; The test results are safe and reliable., improving the safety threshold of DC engineering. The overall design concept can provide reference for the development of DC transmission control and protection platform testing.
