文章基于装机总容量为49 .5 MW的某达坂城实验风电场为研究对象,根据风电场实测数据计算不同有功和无功出力、风电场的无功损耗和母线电压波动情况. 为了让风电场不同容量直驱式机组的无功能够充分发挥出来,文章提出了恒功率因数无功控制方案,建立相关模型,通过仿真论证该方案的可靠性与实用性. 实验结果表明直驱式风电机组的风电场能够充分利用风电机组的无功容量,减少母线汇集点无功补偿容量,基本能满足风电场的无功损耗,提高了母线电压的稳定性和安全性,具有较好的经济效益.

This paper takes an experiment wind farm in Dabancheng of the total capacity of 49 .5 MW as the research object, according to measured data of the wind farm to calculate reactive power loss and bus voltage fluctuations of wind farm with different active and reactive power output.In order to make the direct-drive wind turbine of reactive power of different capacity give full play, the reactive power control scheme of constant power factor is proposed in this paper.We establish the related model and demonstrate the reliability and the practicability of the project through the simulation .The experimental results show that the wind farm of the direct drive wind turbines can make full use of the reactive power capacity of wind turbines to reduce reactive compensation capacity of the bus collection point, and it can satisfy reactive power loss of the wind farm, and improves the stability and safety of bus voltage and it has good e-conomic benefit.
