| 摘 要： | 分别针对江苏沿海110 kV和220 kV 2个典型并网型风电场,利用PSASP建立场内电气微观模型.结合2009年夏季电网背景情况进行仿真,研究了稳态下风电场无功功率与有功功率、机端功率因数的关系.根据仿真结果可知,当风电场采用定功率因数运行时,并网点的无功功率并没有随着有功功率呈现线性增长,而是先增加到最大值后再减...

| Abstract: | The microscopic model is built with PSASP for typical 110 kV and 220 kV grid-connected coastal wind farms respectively.Simulations are carried out based on the actual power grid data of 2009’s summer to study the relationship between the reactive power and the active power for different DFIG power factors.Results show that,when the wind farm operates in the mode of fixed power factor and along with the increase of active power,the reactive power at the connection point increases to its maximum first,then decreases.Sometimes it even absorbs the reactive power from external grid.Comparison between the simulative results and the statistics of online monitoring system proves the rationality of the built models. |
