兼顾抑制超速脱网和无功支撑的双馈风电机组高电压穿越控制策略
High Voltage Ride-through Control Strategy of Wind Turbine With Doubly-fed Induction Generator Considering Suppression of Being Tripped-off From Grid due to Overspeed and Reactive Power Support
摘要
Abstract
With the increasing penetration of wind power,the grid-connected guidelines of countries worldwide require wind turbines with doubly-fed induction generators(DFIG)to own high voltage ride-through(HVRT)capability.Adopting the traditional HVRT control strategy,wind turbines with DFIG may be tripped off the grid due to overspeed during HVRT.For this problem,according to the requirements of the Chinese national standard,firstly,based on the rotor motion equation of DFIG,the approximate calculation formula for the minimum stator active power reference of DFIG without being tripped off from the grid due to overspeed is derived.Secondly,according to the power constraints of DFIG,the mechanism of being tripped off from the grid due to the overspeed of the wind turbine with DFIG under the traditional control strategy during HVRT is clarified.The range of stator voltage swell of wind turbine with DFIG causing tripped-off from the grid due to overspeed under the traditional control strategy is derived.On this basis,an HVRT control strategy with setting stator active power reference of DFIG first combined with grid-side converter(GSC)is proposed to prevent wind turbine with DFIG from being tripped off from the grid and providing reactive power support to the power grid.Based on PSCAD/EMTDC simulation software,the HVRT simulation models of a 1.5MW wind turbine with DFIG and a wind farm composed of wind turbines with DFIGs are constructed,respectively.The simulation results are compared and analyzed between the proposed control strategy and the traditional control strategy,which verifies the effectiveness of the proposed control strategy.关键词
