串并联型风电场机组的过电压协调控制
Coordination Control of Over-voltage for Turbines in Series-parallel Wind Farm
摘要
Abstract
When the wind turbines in the same series branch are operating at different wind speeds,the use of the tradi?tional maximum power point tracking(MPPT)control strategy will lead to over-voltage and over-modulation. To solve this problem,an over-voltage coordination control strategy with MPPT is proposed for the turbines in a series-parallel wind farm. By properly setting the upper limit of direct current(DC)voltage Umax,the output power from turbines at high wind speeds can be coordinated by combining the power-voltage coordination control,which ensures that the DC voltage of turbines can be restricted within a safety range in any operation state. A simulation model was established in the Mat?lab/Simulink platform,and the simulation result were compared between the traditional over-voltage control methods and the proposed strategy in this paper,proving that the proposed strategy was reliable and effective.关键词
