Automatic data exchange for electromagnetic simulation

The most difficult challenge of converting the PSCAD model for use in the Electromagnetic Simulation Program (ESP), developed by China Southern Power Grid (CSG), is that the PSCAD model is graphically-based and the topology information of all elements is realized via the closeness of the coordinates of the element. This paper describes the details of PSCAD models, how to map the PSCAD model into the ESP model, and the automatic process of the conversion. The automatic process eliminates human errors occurring when the data is converted manually. The conversion program was tested successfully on several systems including a real CSG electromagnetic simulation system of 1390 network nodes and 5133 network branches. Using the converted data, ESP's simulation results agree with what is obtained using PSCAD.
