Review of Fault Ride-through Strategies and Key Technologies for Offshore Wind Power Multi-terminal VSC-HVDC Transmission Systems
摘要
Abstract
With the rapid development of offshore wind power,VSC-HVDC has become an effective way for large-scale offshore power delivery.However,this technology also puts forward higher requirements on DC network stability and fault ride-through capability.This paper focuses on large-scale multi-terminal offshore wind power flexible transmission system,reveals the propagation mechanism of fault disturbances in wind farms,converter stations and flexible systems,and systematically combs through the latest research progresses of offshore wind power delivery system to achieve low-/high-voltage fault ride-through.It is reviewed that the multidimensional coordination technique combining control optimization and hardware protection configuration can effectively enhance the fault ride-through capability of the wind power system and improve the stability of the system,and the superiority of the multidimensional coordination technique is verified through the discussion of typical offshore wind power VSC-HVDC engineering cases.Finally,for the future research of VSC-HVDC fault ride-through technology,it is necessary to focus on following breakthroughs:constructing a full-domain nonlinear dynamic model to deeply analyze the fault behavior mechanism,thus laying a rigorous mathemati-cal foundation for the quantitative analysis of fault propagation paths and optimization of ride-through strategy;simultaneously,developing high-performance fault ride-through hardware equipment,focusing on the solution of engi-neering bottlenecks under extreme working conditions,and improving the system fault ride-through capability.关键词
