摘要: |
双馈风电机组(DFIG)机群的拓扑结构对风电场无功优化有较大影响。分析了DFIG的无功出力极限,将DFIG作为风电场连续无功源,计及风电场有载调压变压器分接头设置对DFIG机端电压的影响。以风电场内部有功损耗最小为优化目标建立风电场无功优化模型。最后,以丹麦HornsRev1离岸风电场为例,采用粒子群优化算法对所建立的无功优化模型进行求解。仿真结果验证了所提优化控制策略的安全性和经济性。 |

Abstract: |
The topology of doubly fed induction generators (DFIGs) has a greater impact on optimal reactive power dispatch (ORPD) problem within wind farm. The reactive power limits of DFIG are analyzed, DFIGs are regarded as continuous reactive power sources participating reactive power compensation within wind farm and the impact of on-load tap changing transformers (OLTCs) tap on DFIG terminal voltage is considered. The optimal reactive power dispatch model within a wind farm is formulated with an objective of minimizing active power loss. Finally, the problem of optimal reactive power dispatch within HornsRev1 wind farm in Denmark is formulated and a particle swarm optimization (PSO) algorithm is proposed to get the optimal solution. The test results demonstrate the security and economy of the proposed method in achieving optimal solution. |
