Abstract

The present invention provides an area electric energy quality integration assessment system. The assessment system comprises an electric energy assessment system module, a weight calculation module, a single monitoring point electric energy quality assessment module based on cloud inference and an area electric energy quality assessment module. The present invention further provides the assessment method of the area electric energy quality integration assessment system. The area electric energy quality integration assessment method and system construct a cloud inference assessment model through building the electric energy quality assessment system and performing cloud processing of the electric energy quality assessment index grade threshold value to realize the indetermination division of the electric energy quality classification grade boundary, and employ the subjective and objective integration weighting method to effectively solve the problems that the subjective factor influence is big, the calculation is complex and the assessment object is observation point non-area in the electric energy quality integration assessment. The assessment method provided by the invention can complete the mapping conversion of the electric energy quality integration assessment from quantification input to qualitative inference and then to the quantification output, and therefore, the assessment process is more reasonable, and the assessment result is more credible.

Description

technical field [0001] The invention relates to the technical field of power quality monitoring, and more specifically, to a method and system for comprehensive evaluation of regional power quality. Background technique [0002] As a special commodity, electric energy has the characteristics that it cannot be stored in large quantities for a long time and involves the three parties of generation, supply and consumption at the same time. Therefore, the evaluation of power quality cannot completely depend on the power production enterprise, and the opinions of the power supply party and the power consumer should also be considered comprehensively. In addition, with the gradual improvement of the user-side power quality monitoring network, the power quality needs to be objectively and reasonably evaluated for the regional power grid, highlighting the differences in the power quality of each monitoring point in the region, and taking corresponding measures based on the evaluation...
