摘要:针对风电场并网电压源直流输电系统,在αβ坐标系下VSC-HVDC系统离散化数学模型基础上,结合瞬时功率理论和空间矢量脉冲宽度调制,提出了一种适用于VSC-HVDC系统的新开关表的直接功率控制。其中,风电场侧采用定有功功率和无功功率,电网侧采用定直流电压和无功功率,利用MATLAB/Simulink搭建相应的仿真模型,通过对有功、无功阶跃突变工况的仿真分析,验证了该方案的有效性和可行性,为风电场并网电压源高压直流输电系统提供了一种可行的控制方案。
According to the grid connected voltage source DC transmission system in wind farm, the discrete mathe- matical model VSC-HVDC system in reference frame is derived. A novel direct power control strategy in the voltage sourced converter is proposed based on instantaneous power theory and space vector pulse width modulation in the pa- per. Constant active and reactive power controller is used in the wind farm side, and a constant DC voltage and con- stant reactive power controller is used in the grid-side. A case of two-terminal VSC-HVDC system for grid connection of wind farms is developed in MATLAB/Simulink. The simulation results show the effectiveness and feasibility of the proposed control methods which provide a viable control solution in voltage sourced converter based high voltage direct current systems for offshore wind farm.
