Model Conversion From PSS/E To PSASP Based On Custom Pattern And Simulation

The development of power system puts forward higher requirements to power system simulation. Using single simulation software may not sufficiently meet the need of factual research. The usual practice is to select simulation software according to the scale of actual system, the purpose of simulation and the characteristic of different software. Using several simulation software Comprehensively to reduce the gap of simulation results and the actual operation conditions. The data sharing between different simulation software becomes a problem to be solved.The thesis comes to the need of internationalization of PSASP. On the basis of comparing power flow models and dynamic models between PSS/E and PSASP, the model converting relationship is presented, a model conversion method based on custom pattern is put forward, and a conversion program is developed. The main contents of this thesis are as follows:(1)Compare the power flow models between PSS/E and PSASP. The studied models are bus model, branch model, transformer model and load model. The model conversion relationship is gived.(2)Compare the dynamic models between PSS/E and PSASP. The studied models are generator model, excitation system model, governor model, stabilizer model, load model (load characteristic and motor model), SVC model and DFIG model. The model conversion relationship is gived.(3)A model conversion method based on custom pattern is put forward. The method is universal and easy to achieve.(4)A conversion program is developed using C++and XML, and it has passed the project acceptance.(5)The correctness of the model converting relationship and the practicability of the program are verified by simulation.
