Power Vector System Simulation Design Based on MATLAB Difference Frequency Control

High voltage transmission is a complex process, because partial discharge and various problems of lines will produce current response of different frequency, so it needs vector synthesis in different time and space. In this paper, based on the theory of vector synthesis, through the SIMULINK module of MATLAB software voltage is simulated, we obtain the coupling graph and vector synthesis graph of different voltage. From the curve we can see that before vector synthesis, the voltage has different frequencies and the peak output values, after vector synthesis, the voltage has stable frequency and peak output values, with good transmission effect. It provides the theoretical reference for the research on high voltage power system.
