The Power Quality Evaluation Method Based on the Matter-Element Comprehensive Evaluation Method

Abstract:

As for the pricing by electrical energy quality and the decision of rewards and penalties based on the examination at assessment point, Comprehensive evaluation on power quality is one of the principal foundations. To analysis and evaluate electric power quality for electric power company is a focus research at present. In this paper, the power quality evaluation model based on the matter-element extension theory is applied to power quality evaluation service. For power quality evaluation system of the characteristics of the complexity and incompatibility between various indicators hierarchies, this paper applied the theory of matter-element extension constructing Matter-element model, and identified level of power quality of power supply company through the calculation of weight and the correlation service. Taking GanSu Grid Company as an example to evaluate power supply quality, the results show that the evaluation results of power quality evaluation method based on the matter-element evaluation method are more objective, more precise and more reasonable.
