摘要

电压无功灵敏度参数的准确性直接决定风电场自动电压控制（AVC）性能,其偏差将导致控制性能劣化,无法保障并网电压质量。因此该文提出一种风电场AVC子站电压无功灵敏度自主感知及控制参数自适应跟随方法。首先分析影响风电场并网点电压无功灵敏度的关键因素。由此,提出一种考虑运行方式和线路长度修正的风电场AVC子站电压无功灵敏自主感知方法,通过风电场AVC实时量测数据,在线计算风电场并网点电压无功灵敏度。其次,基于前述灵敏度自主感知方法,根据调节过程中电压变化特征提出一种AVC控制参数自适应跟随方法,改善风电场电压控制中存在的多次调节无法进入死区、电压振荡等问题。最后,在Matlab/Simulink中搭建某风电汇集区域的仿真模型,验证所提方法的准确性与有效性。

Abstract

The accuracy of voltage and reactive power sensitivity parameters directly determines the performance of wind farm automatic voltage control（AVC）. Deviation in these parameters leads to degraded control performance and an inability to ensure grid-connected voltage quality. To address this,this paper proposes a method for autonomous sensing of voltage and reactive power sensitivity and adaptive control parameter tracking in AVC sub-stations of wind farms. Firstly, the key factors affecting the voltage and reactive power sensitivity of wind farms are analyzed. Therefore, a method for autonomous sensing of voltage and reactive power sensitivity of wind farm AVC sub-stations considering operation modes and line length correction is proposed. Through real-time measurement data of wind farm AVC, the voltage and reactive power sensitivity of the wind farm grid connection point is calculated online. Secondly, based on the proposed sensitivity-based autonomous sensing method, an AVC control parameter adaptive following method is proposed based on the characteristics of voltage changes during the adjustment process to improve the problems of multiple adjustments failing to enter the dead zone and voltage oscillation in wind farm voltage control. Finally, a simulation model of a wind power collection area is built in Matlab/Simulink to verify the accuracy and effectiveness of the proposed method.
