Capacity Configuration and Coordinated Operation of A Hybrid Wind Farm With FSIG-Based and PMSG-Based Wind Farms During Grid Faults - 2017

ABSTRACT:

This paper mainly proposes a capability configuration strategy for a hybrid wind farm with mounted-speed induction generator (FSIG)-primarily based and permanent magnet synchronous generator (PMSG)-primarily based wind farms during grid faults. In this paper, FSIG-primarily based wind farm realizes low voltage ride through (LVRT) with the associated control of nearby PMSG systems as StatComs to produce the specified reactive power. By establishing the mathematical model of hybrid wind farm containing network parameters, the operation characteristics of the FSIG-primarily based wind farm throughout grid faults are analyzed very well. Based on the characteristics and the critical clearing time of FSIG-based wind farm, a novel capability configuration methodology for the hybrid wind farm is proposed to calculate the required reactive power of FSIG-based mostly wind farm for a LVRT operation. Based on the capacity configuration result, the minimum installed capacity of PMSG-based mostly wind farm may be determined. Taking into account the impact of reactive power compensation capacity and grid transmission line parameters, the coordinated LVRT capability of the hybrid wind farm is then analyzed. Finally, simulation and experimental results demonstrate the effectiveness of the proposed capacity configuration method and the coordinated operation performance of the hybrid wind farm respectively.
