摘要
该文从风电场经直流送出系统模型出发,分析了换相失败下电网和风电场暂态电压特性及连续换相失败机理,并提出从无功补偿的角度来抑制换相失败后的暂态电压现象。最后,以某省风电场直流送出系统为例进行了仿真分析,特别针对连续换相失败场景下风电场的影响特性、送端系统暂态电压及抑制措施进行了仿真分析,并进行了理论验证。
Starting from the DC transmission system model of wind power,this paper explores the transient voltage characteristics of the power grid and wind farm,the mechanism of continuous commutation failure,and proposes the overvoltage suppression measures from the perspective of reactive power compensation.A provincial wind power DC transmission system is used as examples for the simulation analysis,the impact characteristics of the wind farm,the transient voltage and the suppression measures of the transmission system under continuous commutation failure are studied especially,and the theoretical verification is carried out.
