风电场无功补偿装置改造方案

Reform Scheme of Reactive Power Compensation Devices in Wind Farm

对内蒙古太旗贡宝拉格风电场的无功功率特性进行了研究并取得如下成果:计算风电场无功损耗以及风电并网运行后的系统潮流,确定风电场由于损耗所需要安装的无功补偿容量;研究治理三相不平衡所需要的无功补偿容量和装置类型;根据实际情况确定风电场综合无功补偿配置,提出综合无功补偿的调节策略。实践表明,该方案有效地解决了风电场无功损耗和三相不平衡问题,具有较高的理论价值。

This paper investigates reactive power characteristics of GongBaoLage wind power station in Taiqi,Inner Mongolia and obtains the achievements as follows：Calculates reactive power loss and load flow in power systems after the generator is combined to the grid to determine the reactive power compensation capacity in the wind farm,which needs to be installed due to the loss;Studies the reactive compensation capacity and device type needed in the governance unbalanced three-phase current needed;According to the actual situation,determines integration allocation of the reactive power compensation.It also puts forward the comprehensive reactive-power compensation adjustment strategy.Practice shows that this scheme can effectively solve the reactive power loss and unbalanced three-phase power in the wind farm and the theory has high value.
