Research on Building the Mathematical Model of Voltage Regulation System in Aero-power

The working principle and composition of voltage regulation system for 60kVA AC power are studied. Based on a series of experiments, the mathematical model is built successfully. Simulation and analysis are performed by using MATLAB's strong functions in model identification and numerical calculation, and the experimental waveform is presented subsequently. Both results agree well with theoretical analysis, which points out that when improving the steady-state characteristic, the exciting current feedback also has influence on the dynamic characteristic. Therefore the method of establishing model as well as the experimental result is proved to be correct. It will provide important theoretical foundation for parametric programming and performance analysis of voltage regulation system. In addition, it will have a certain reference to studying the control algorithm of digital voltage regulator.
