并网风电系统功率因数校正技术的发展

Development of Power Factor Correction in Grid-connected Wind Power Generation System

风力发电已成为目前新能源发电技术中前景看好的新能源利用方式之一,随着风电规模的扩大,并网风电系统功率因数对电网的影响不容忽视,并网风电系统功率因数校正技术研究成为风电技术发展中的重要课题之一。从功率因数的定义出发,分析了并网风电系统中景响功率因数的原因和并网风电系统中的功率因数校正的原理,对各功率因数校正技术进行比较和分析,综述了并网风电系统中功率因数校正的现状及发展。

Wind power generation becomes one of the promising new energy generation technologies at the present time. With the cxpansion of the scale of wind power,the impact of power factor in grid-connected wind power system on the grid can not be ignored, so the power factor correction technology in grid-connected wind power sysytem becomes an important issue the development of wind power. This paper analyses some factors which have an effect on power factor in the system from the definition of the power factor, introduces some main principles for correcting the factor and compares and analyzs these power factor correction technologies. The development of this technologies is surveyed in the paper.
