摘要
对基于恒速风电机组的风电场并网过程进行了分析并提出了改善措施。在DIgSILENT/PowerFactory中建立了恒速风电机组风电场的等值模型,分析了大规模风电场并网时对系统的影响。研究结果表明,对于接入弱系统的大规模风电场,为了减小风电机组并网所带来的冲击和避免系统电压失稳,应对同时并网的风电机组的数量有所限制。
The interconnection process of fixed speed wind turbines based wind farm with power grid is analyzed and related improving measure is put forward. By use of DIgSILENT/PowerFactory software, an equivalent model of wind farm based on fixed speed wind turbines is built up, by which the influence of the interconnection process on power grid is researched. Research results show that for large-scale wind farm interconnected with weak power grid, in order to decrease the impact of the interconnection process on power grid and avoid voltage instability of power grid, the numbers of fixed speed wind turbines, which are interconnected with the power grid at the same moment, should be restricted.
