考虑风电场无功调节能力的无功电压控制分区方法研究
|
摘要
分析双馈型风电机组(DFIG)风电场的P-Q容量曲线,提出同时考虑区域电气距离和区域内静态无功平衡的含风电场电力系统无功电压控制分区方法,对处理含DFIG方案,并结合New-England 39节点系统来验证方法的有效性。在无功控制分区过程中引入负荷被控空间的概念,采用先无功源节点聚类,后负荷节点归类的两阶段无功控制分区方法,有效解决了因风电有功出力影响其无功容量而带来的分区连通性和无功平衡问题。
Reasonable and effective partition is the premise to realize regional reactive power/voltage control. In this paper,the P-Q capacity curve of doubly fed induction generator(DFIG)wind farm was analyzed,and the reactive power/voltage control partitioning model of power system with wind farm was created considering both region electrical distance and static reactive power balance. For reactive power/voltage control partitioning of power system with wind farm,a comprehensive treatment method was presented and tested on New-England 39 bus system to verify its effectiveness. In the partitioning process,the concept of load controlled space was introduced,reactive power source nodes were firstly clustered,and load nodes were then classified in the second stage,effectively solving the connectivity problem caused by coupling of active power and reactive power output of wind farm.
