Title Model Comparison and Development of Data
Interface Program between BPA and PSS/E
Abstract
Power system simulation is the foundation of power system designing, planning and operation. It has become the essential tool to research the power system dynamic characteristics. Along with the introduction of overseas power system simulation software, it becomes the necessity to study similarities and differences between them and the original software, and develop software data interface program. This article does the main work as follow: Research the similarities and differences of generator model and load model between power system simulation software PSS/E and BPA and carry on the model parameter transformation; contrast the simulation results of BPA and PSS/E, and carry on the error analysis by using the power system simulation error indicator, which full prove the validation of model transmission of the two software; develop the data interface program of BPA and PSS/E, and transmit the Jiang Su power grid data from BPA format to PSS/E format, which get close results in simulation.
Key words: Power system simulation generator model load model data interface program
