分析了大规模海上风电场的并网需求,比较了高压交流输电系统、基于电网换相换流器的高直流输电系统和电压源换流器的直流输电系统的技术特点,对系统损耗做了数值分析,从而得出各种输电系统的适用范围。
In this paper the grid-connected demand of large-scale offshore wind power was analyzed , and a detailed comparation is presented for three kinds of transmission technologies : HVAC ( high vohnge alternating current), HVDC(high vohnge direct current) based on line commutated converter(LCC), HVDC based on voltage source converter(VSC). The losses are made numerical analysis for gaining the application scope of various transmission systems.
