Simulation of Wind Turbine Based on Cascade Form High-voltage Inverter

设计了一套基于级联型变流器的风力发电系统模拟装置。该装置的模型以风力机能量转换原理为基础,通过风力发电变流器控制异步电机模拟实际的风力机。该装置满足了双馈发电机在各种状态下研发的需要,可以方便的用于实验室条件下的风电技术的研究。

A wind turbine simulator with the same characteristics of speed as those of the actual wind turbines has been designed. The mathematic model is based on the energy conversion principle of wind turbine and it simulates the actual wind turbine through the high-voltage inverter which controls an asynchronous machine. It satisfies the need of the research for the operation states when the generator works in variable speed and it makes the research on the wind power technology convenient in the laboratory conditions.
