并网型风力发电系统电压稳定研究现状

风力发电作为目前应用最广泛的新能源,其接入电力系统后对电网电压稳定的影响得到了人们的广泛研究。由于风力发电不同于常规能源发电,所以影响并网型风力发电系统电压稳定的因素也和常规电力系统范畴内影响电压稳定的因素有所不同。分析研究并网型风力发电系统运行特性,了解其电压失稳机理,进一步为保证系统电压稳定以避免发生电压崩溃提出相应的控制策略,是当今学术界的一个重要研究方向。文中对上述问题的相关研究成果进行了综述,并做了相应总结。

Updated Research of Voltage Stability for Grid-Connected Wind Power System

Wind power generation is the most widely used new energy,its approaches to power system will probably greatly impact the voltage stability of power grid and which is receiving more attention in recent years.Due to the wind power generation is different from the conventional energy,the factors effecting voltage stability of the grid-connected wind power system are different from the scope of conventional power system.So it is very necessary to analyze the operating characteristics of grid-connected wind power system,and to understand the mechanism of voltage instability.In addition,how to implement affiliated strategies for grid-connected wind power system to ensure voltage stability and avoid voltage collapse is another important issue currently.This paper provides an overview to the relevant research issues related to the voltage stability of grid-connected wind power system and makes the appropriate conclusion.
