摘　　要：大容量并网风力发电对电网影响日益明显,配网侧接入风力发电后负荷特性描述问题成为研究重点。在提出定量分析指标的基础上,以统计规律法为检验方法,分析不同运行方式风力发电对综合负荷特性的影响力,并验证异步电机并联静态负荷的广义负荷模型对含风力发电的负荷特性描述能力;指出风力发电对负荷特性的主要影响因素为接入容量与接入位置,并比较两种因素对负荷特性的影响力。The influence of the large scale wind power in the power system is increasingly obvious.How to describe the load characteristic considering wind power becomes more important.Based on the proposed quantitative indicators and using the general theory of statistics,this paper analyzes the impact of different operation modes of wind power on the comprehensive load characteristic,and verifies the descriptive ability of generalized composite load model of asynchronous machine in parallel with static load on load characteristic considering wind power generation.That the main influence factors of load characteristic are the capacity and the location of the wind power is pointed out,and the impact of the two factors in load characteristic are compared.
