Design and Implementation of Human-Machine Interface of LVRT Simulation Test System of Wind Turbines

The increasing of installed capacity of large wind power generators requires the system of LVRT(low voltage ride through) ability. It is costly and time consuming to develop a physical device for LVRT test. Based on modular design idea, the LVRT simulation model of wind power was established by Matlab/simulink, and the simulation-testing system of wind turbine LVRT based on graphical user interface is designed by GUI programming environment provided by Matlab. The GUI and Simulink data exchange technology is used to achieve the parameter setting, the real-time display of waveform and data, fault partition and deviation calculation, etc. The results show that the system is easy to operate and strong human-computer interacted, and it can get the high credibility simulation data, intuitive graph curve as well as the test report in accordance with the standards, which provides a software platform with low cost and high reference value.
