针对国家电网公司对风电场提出有功功率自动调节的要求,结合风电场风机的布置特点,采用拉格朗日函数,引入各台风机、电缆、变压器等参数和限制条件,通过计算电能在传输过程中电量损失最小,来确定各台发电机分配负荷的大小,达到向电网输送更多电量的目的。该策略在风电场经过实际应用,取得了较好的应用效果,证明了其可行性。
According to the requirements of State Grid Corporation of China (PRChina) for the automatic regulation of active power in wind farms, the parameters of wind turbines, cables and transformers are introduced by Lagrange function in combination with the layout of wind turbines in wind farms. The smallest loss of CLP, to determine the size of each generator load distribution, to achieve more power transmission to the power grid purposes. The strategy has been applied in wind farms and achieved good results, which proves its feasibility.
