摘要
为了实现将轻型高压直流输电系统应用于海上风电传输,从轻型直流输电系统原理与特性入手,通过其数学等效电路图推导出有功、无功功率表达式,在此基础上分析了其换流器的3种基本控制方式.结合交流输电和传统直流输电系统,分析了轻型直流输电系统的性能优势,分别从技术角度与经济角度分析了将轻型直流输电技术应用于海上风电系统的可行性,并研究了相关工程案例.
In order to apply VSC-HVDC system on offshore wind farm,the principle and characteristics of VSC-HVDC system is analyzed.Through its mathematical equivalent circuit,active power and reactive power formulation are deduced.Based on the formulation,three basic control modes of inverter are analyzed.Combined with AC power and traditional HVDC system,advantaged performance of VSC-HVDC system is analyzed.From the terms of technology and economy,the feasibility of applying VSC-HVDC system on offshore wind farm is analyzed and the relevant engineering cases are studied.
