综合量化评估电能的质量,是衡量电能质量优劣与电价制定的依据之一,有利于实现按质论价、优质优价的购电原则.为了综合评估电能质量,根据电能质量评估的实质,提出基于遗传算法的Shepard插值理论用于电能质量的评估,并构建了电能质量综合评估的Shepard模型(SP模型).对于模型中的非线性优化问题,采用加速遗传算法来解决,取得了很好的效果.实例计算结果表明,SP用于电能质量综合评估,其评估结果更为客观、合理.

The synthetic quantified evaluation for power quality is one of the gist to weigh excellent or inferior of the power quality, and this is propitious to realize the electricity-purchase principle of discussing the price according to quality and high quality high price, thereby serve as to build the equitable electric power market. The problem of power quality evaluation is a desiderate problem. Also world countries have establish a series of the power quality standards, but this standards can only used to confirm the power quality is eligibility or not, can not confirm the power quality is exce...
