Study on Joint Application of New SFCL and STATCOM in Wind Power Integrated System
A new superconducting fault current limiter(SFCL)and static synchronous compensator(STATCOM)are jointly applied to solution of three-phase short-circuit fault voltage dips in wind power integrated system.By establishing a simulation model,three scenarios are set up in terms of voltage stability improvement and short-circuit current suppres-sion,and the scenarios are compared with each other.It can be concluded that in terms of voltage stability improvement,new SFCL and STATCOM have the best combined control effect,and in terms of short-circuit current suppression,new SFCL alone has the best control effect.Considering both aspects,the combined control of new SFCL and STATCOM has the best effect on improving transient stability of wind power integrated system,which can not only reduce bus voltage dip,but also suppress fault short-circuit current and maintain transient stability.
