Studies On Comparison Of Models And Calculation Results In BPA And PSS/E And Data Interface Program Developing

Power system simulation is the foundation of power system designing, planning andoperation. It has become the essential tool to research the power system dynamiccharacteristics. Along with the introduction of overseas power system simulation software, itbecomes the necessity to study similarities and differences between them and the originalsoftware, and develop software data interface program. This article does the main work asfollow: Research the similarities and differences of generator model and load model betweenpower system simulation software PSS/E and BPA and carry on the model parametertransformation;contrast the simulation results of BPA and PSS/E, and carry on the erroranalysis by using the power system simulation error indicator, which full prove the validationof model transmission of the two software;develop the data interface program of BPA andPSS/E, and transmit the North-China power grid data from BPA format to PSS/E format,which get close results in simulation.
