Design of automatic performance test system for CPS

In order to satisfy the needs of comprehensive and accurate performance test for CPS (Control and Protective Switching), an automatic performance test system was studied in this paper. The hardware structure and software was introduced in detail; the hardware system was made up of the industrial control computer, the three-phase current generator, adjustable single-phase power, pneumatic fixture, and so on. The test system software developed by LabVIEW was mainly used to achieve the functions of data acquisition, data processing and data display. The designed system is able to automatically test all functions of different types of CPS, including measurement function, communication function, multiple protection function, and so on. Practical application shows that the test system has following properties: high precision, low cost, strong anti-interference and convenient maintenance.
