基于模糊控制的风电场无功补偿

Department of Wind Farm Reactive Power Compensation Based on the Fuzzy Control

由于风能的间歇性和不确定性使风力发电机组发出的功率不稳定,这样会影响到风能的电压,引起风电场的电压波动,最终导致电网的无功能力下降。因此,为了稳定风电场的电压,解决风电场的无功功率不足的问题,提出了一种将模糊控制应用于风场无功补偿的方法。这种方法介绍了模糊推理的整个模糊控制技术,并对无功补偿进行仿真。仿真结果表明模糊控制技术可以对风电场电压、无功进行补偿。

Due to the intermittent and uncertainty of wind power from the wind turbine is not stable, it affects the wind power voltage, causes the voltage fluctuation of wind farm, eventually resulting in a decline in the reactive ability of the power grid. Therefore, in order to the voltage stability of wind farms, solve the problem of insufficient reactive power of wind farm, this paper proposes a fuzzy control method which is applied to reactive power compensation for wind field. This method introduces fuzzy reasoning of the fuzzy control technology, and the simulation of reactive power compensation. The simulation results show that the fuzzy control technology can be carried out on the wind farm voltage and reactive power compensation.
