摘要
随着大规模风电接入电力系统及电力用户对电能质量的要求越来越严格,准确全面地对电能质量综合评估对实现风电场电能质量按质定价越来越具有重要意义。本文提出一种考虑分功率区间的风电场电能质量综合评估方法。首先,利用层次分析法对电能质量指标在分功率区间下的数据进行加权,并考虑短板效应对低指标权重放大;然后,以风电场规模及无功补偿设备容量配置作为输入数据,利用数据包络分析(data envelopment analysis,DEA)计算各风电场的电能质量综合评估结果;最后,某省网主要风电场电能质量DEA评估。结果表明,本文所提方法更准确全面。
With the development of the wind plant and more and more power customers are strict with power quality, comprehensive evaluations of power quality and improvement have become more and more important. A new power quality comprehensive evaluation method for wind plant considering fractional power section is proposed. Firstly, the hierarchy analysis is used to establish the hierarchical structure of the by fractional power section power quality index data, and each section data is weighted. Then, take the wind plant scale and reactive power compensation equipment capacity allocation as input data, the wind plant quality evalution result is proposed by data envelopment analysis （DEA） method. Last, the power quality evalution result of province wind plants show that the proposed method is more accurate and comprehensive.
