Abstract

The invention relates to the field of power equipment energy consumption monitoring and energy-saving evaluation. The invention particularly relates to a quantitative analysis method for influence ofpower quality on capacitor comprehensive energy consumption. The method mainly comprises the following steps: (1) measuring and acquiring power quality data parameters of a capacitor from a power quality monitoring device; and (2) carrying out quantitative analysis and calculation according to capacitor energy consumption caused by harmonic waves, capacitor energy consumption caused by voltage deviation and capacitor energy consumption caused by three-phase unbalance degree. The method provides practical and effective help for quantitative analysis of capacitor energy consumption distributioncharacteristics, research and formulation of capacitor energy-saving measures and the like, and provides effective data support for analysis of capacitor energy consumption.

Description

technical field [0001] The invention relates to a quantitative analysis method for the influence of electric energy quality on the comprehensive energy consumption of capacitors, and belongs to the field of energy consumption monitoring and energy-saving evaluation of electric equipment. Background technique [0002] Energy saving and loss reduction is one of the development directions of the smart grid. As the main reactive power compensation device, power capacitors are used in large quantities in the power system, which plays an important role in improving the stability of the power system, improving power quality and reducing the loss of the power grid. important role. In recent years, with the wide application of power electronic equipment and inductive loads in the distribution network, the problem of insufficient reactive power in the power grid system has become increasingly prominent. To solve this problem, it is usually necessary to install reactive power compensat...
