摘要/Abstract

摘要： 研究了风电场分别通过电压源型高压直流输电（VSC-HVDC）和交流输电（HVAC）2种方式并网的问题;基于dq同步旋转轴变换的VSC-HVDC的数学模型,设计了两端换流站的控制策略;在电力仿真软件DIgSILENT/PowerFactory中建立了风电场的2种（AC、DC）并网接入方式模型,针对受端换流站交流母线短路故障工况进行了仿真验证,分析了风电场母线电压、输出功率、风力机转速以及风电场当地负荷的功率等电气量响应情况。结果表明：在故障扰动情况下,VSC-HVDC对提高风电场当地负荷用电可靠性、风电场母线电压、抑制风电机组输出功率波动以及避免风电机组转矩不平衡引起的发电机超速效果最佳,设计的控制方案有效可行。

Abstract: Two integration modes including voltage source converters(VSC-HVDC) and AC transmission(HVAC) are studied for wind farms. Based on the VSC-HVDC dynamic model which is built in dq synchronous frame, a control strategy is designed for the converter stations on both ends. Two wind farm integration models (AC and DC) are built in DIgsilent/Power Factory and the conditions of the AC bus short-circuit fault at the receiving converter station are simulated and verified by the models. Based on the simulation, the local load power, bus voltage, output power and the speed of generators of the wind power system are then studied. The results demonstrate that the VSC-HVDC can improve voltage, reduce the oscillation of active power and avoid over-speeding during system fault. The control strategies are proved to be feasible.

Key words: VSC-HVDC, wind farm, control strategy, wind power, local load, system fault, transient stability, simulation analysis
