Coordinated Control of Reactive and Active Power for Direct-Drive Wind Farm
针对因风速扰动、负荷变化等引起的缓慢且幅度较大的电压波动,提出了一种基于直驱式风电场的功率协调控制策略。通过调节桨距角降低有功出力,从而增加风电场无功功率的调节能力,维持风电场出口电压水平,从而预防或避免由于电压偏差较大引起风电机组进入低电压穿越模式,造成其对电网更大的冲击。仿真结果表明,上述方法能够合理协调控制风电场的有功和无功出力,有效为风电场出口电压提供无功支持,从而维持接入点电压的稳定性。
In allusion to slow and considerable voltage fluctuation caused by wind speed disturbance, load variation and so on, a power coordination control strategy for direct-drive wind farms was proposed. Through decreasing active power output by adjusting pitch angle, the ability of adjusting reactive power of direct-drive wind farm was enhanced and the output voltage level of direct-drive wind farm could be maintained, thus it could be prevented or avoided for win…查看全部>>
