Abstract

The invention provides a data file conversion method, and the method is applied to data file conversion, from PSD-BPA to PSS / E of electric power system simulation software. The method comprises the following steps of: reading a data file; identifying PSD-BPA data of the electric power system simulation software; converting load data; converting generator data; converting parallel capacitor data; converting converter bus data; converting circuit data; converting DC circuit data; converting transformer data; converting converter transformer data; converting DC system data; outputting a tidal data file; and respectively carrying out input according to above obtained results and tidal file format requirements in PSS / E simulation software so as to complete the conversion of the tidal data file. According to the method provided by the invention, the data file conversion, from PSD-BPA to PSS / E of the electric power system simulation software is realized, and a program is directly called under a PSS / E environment, so that the conversion can be adapted to a plurality of PSD-BPA input formats and is not limited to network size, the network data of large-scale electric power systems can be converted, the operation is convenient and simple, the conversion is rapid and the conversion result is correct.

Description

technical field [0001] The invention relates to a data file conversion method in the technical field of power system automation, in particular to a power system simulation software data file conversion method from PSD-BPA to PSS / E. Background technique [0002] Power system simulation analysis is an important method for power system planning and operation characteristic analysis, which provides a scientific basis for the safety, reliability and economy of power system dispatching and operation. There are many types of power system simulation software, and the functions of different software are quite different, which can meet different simulation needs. According to the different needs of the power system, appropriate software is selected for calculation and analysis, and more accurate calculation results can be obtained by using different software simulation calculations for the same problem. [0003] PSD-BPA software is a power system simulation software commonly used by ...
