海上风力发电机组单机无功响应控制

Offshore Wind Turbine Stand-Alone Reactive Response Control

当前海上风力发电机组无功功率分配策略一般是根据0.95的功率因数进行上限设定,但目前各地电网需求无功上下限更高,且各风电场所处的位置电网质量差异,导致海上风力发电机组在无功调控时存在端电压超出正常的情况,因此需求风力发电机组具备更大容量的无功支持。通过优化风力发电机组无功功率算法,进一步挖掘机组可发无功潜力,满足电网需求,同时提升风力发电机组的电网适应性。

The current reactive power distribution strategy of offshore wind turbines is generally based on the upper limit setting of 0.95 power factor,but the current demand for reactive power in various regions is higher,and the quality of the power grid at the location of each wind power site is different,resulting in wind turbines During reactive power regulation,there is a situation that the terminal voltage exceeds the normal value,so the offshore wind turbine generator is required to have a larger capacity of reactive power support.By optimizing the reactive power algorithm of wind turbines,the potential of generating reactive power is further explored to meet the needs of the power grid,and at the same time,the grid adaptability of the wind turbines is improved.
