不同风电场模型对风电场电压的影响评估
Assessment on the effect of different kinds of wind farm models on wind farm voltage
摘要
Abstract
At present, the simulation calculation for practical power system is usually carried out by regarding the wind farm as one wind power unit. Along with the increase of the grid connected wind power capacity, the error caused by simulation calculation on one equivalent wind turbine should not be neglected, the error may result in the misoperation of the internal protecting device in the wind farm. The paper carried out the detailed comparison on the effect of different kinds of wind farm models on wind farm voltage, and gave the quantitative index. By means of computer simulation analysis, several conclusions are drawn: different kinds of wind farm models make different effects on voltage of wind farm and point of common coupling (PCC). When regard the constant speed induction motor based wind farm as one wind power generator, the average calculation error of the phase voltage at the terminal of the wind farm could reach a value of 16.776%. As a result, for guaranteeing the simulation accuracy and the right operation of the wind farm protection device, it should regards the wind farm as several wind power units when carrying out the simulation on power system.关键词
