基于并联自抗扰VSC的直驱风电场并网系统次同步振荡抑制策略
Subsynchronous oscillation mitigation strategy based shunt active disturbance rejection VSC for direct-drive wind farm grid-connected system
摘要
Abstract
In order to solve the problem of sub-synchronous oscillation(SSO)in direct-drive wind farm grid-connected systems,an SSO mitigation strategy based on shunt active disturbance rejection voltage source converter(VSC)is proposed.Using the advantages of strong anti-interference ability and high adaptability of linear active disturbance rejection control,a linear active disturbance rejection controller is proposed to replace PI control module of parallel VSC to estimate and compensate SSO disturbance of direct-drive wind farm grid-connected system,and the external disturbance has little influence on the suppression effect.The theoretical analysis is verified based on PSCAD/EMTDC simulation,and the results show that the proposed shunt active disturbance rejection VSC sub-synchronous oscillation suppression strategy can effectively suppress the SSO of the system under different working conditions,and has strong robustness.关键词
