Research on Grid Impact Suppression in Hydraulic Wind Turbine
摘要
Abstract
Taking a hydraulic wind turbine as the research obj ect,mathematical models for wind turbine,fixed displacement pump�variable displacement motor of hydraulic system,synchronous genG erator and excitation system were established,for the problem of grid impact in hydraulic wind turG bine.The mathematical models for impulse current and impact torque were derived.A suppression method for grid impact in hydraulic wind turbine was proposed,by the combination of generator speed control,excitation voltage control and quasi�synchronization monitoring.Using 30 kV�A hydraulic wind turbine simulation platform as the simulation and experimental foundation,the grid impact supG pression was researched.Simulation and experimental results show that the grid impact suppression proposed has good control effect for impulse current and impact torque,achieving the flexible grid�connection for generator.关键词
