风电并网对电力系统暂态稳定的影响

Influence of wind power integration on power system transient stability

随着社会经济的快速发展,作为一种重要的可再生资源,风力发电已成为当前发电技术最成熟、最具开发潜力的发电技术。在实际应用中,由于大规模开发风力资源、单一风电场装机容量不断提高,电网系统中风电占比日益增加。随着风电的不断接入,电网系统原潮流分布发生了变化,受风速随机与间歇性影响,其输出功率有一定的波动性,严重影响到电网电压的稳定。因此,在开发与规划风电场建设中,风电并网对电力系统电压稳定性的影响做深入研究,意义深远。

With the rapid development of social economy,as a kind of important renewable resources,wind power generation technology has become the most mature,the most development potential of power generation technology.In practical applications,due to the large scale development of wind resources,a single wind farm installed capacity,power grid system,the increasing proportion of wind power.With the continuous wind power access,the distribution of the original power flow of the grid system has changed,and the output power of the wind speed is affected by random and intermittent,and its output power has a certain volatility,which seriously affects the stability of the power grid voltage.Therefore, in the development and planning of wind farm construction,wind power grid connected to the power system voltage stability of the impact of in-depth study,far-reaching significance.
