Abstract

Wind power grid integration via fractional frequency transmission system is an effective approach to large-scale longdistance transmission of wind power, which could solve the problem of limited transmission distance of industrial frequency AC cable and save the investment cost of offshore platforms when applied to offshore wind power. Generator-side converter could also achieve the maximum wind power capture for each generator. This paper describes the principles of the FFWPS (Fractional Frequency Wind Power System) with generator-side converter, and analyzes the frequency characteristics of the system with simulation models. Simulations of variable wind speed state and LVRT is conducted, which verifies the feasibility and efficiency of the system.
基于pmsg的分频风力发电系统
分频输电系统整合风电并网是实现风电大规模远距离传输的有效途径,可解决工频交流电缆传输距离有限的问题,并可在海上风电中应用,节约海上平台投资成本。发电机侧变流器也可以实现每台发电机最大的风力捕获。本文介绍了带发电机侧变流器的分频风力发电系统的工作原理,并用仿真模型分析了该系统的频率特性。对变风速状态和LVRT进行了仿真,验证了系统的可行性和有效性。
