Embodiment Construction

[0035] The invention provides a method for collecting power quality data of electric power users based on economic evaluation. The method specifies the data to be collected for evaluating the economic loss of power quality, and proposes a feasible data collection method and a processing method for the collected data. Specifically guide power users to collect data before conducting power quality problem loss assessment. The collection of power quality data based on economic losses has a direct impact on the evaluation of economic losses caused by power quality problems for power users. This method proposes a comprehensive and accurate data collection range and processing method through detailed decomposition, induction and summary of power quality data of power users, which can lay a foundation for power users to quantitatively evaluate losses caused by power quality problems.

[0036] The present invention will be described in further detail below in conjunction with specific ...

Abstract

The invention provides a power consumer power quality data collection method based on economic evaluation. The method includes S1), determining user-oriented power quality problem classification, and defining collection ranges of power consumer power quality data according to sensitivity of electric equipment to power quality; S2), determining specific power quality technical data required to be collected according to the collection ranges of different power consumer power quality data; S3) for actual conditions of power consumers, collecting the power quality technical data by a simulating calculation method or a field measurement method; S4), subjecting the collected power quality technical data to statistical treatment. The power consumer power quality data collection method can lay the foundation for evaluation of production losses caused by power quality problems of the power consumers.

Description

technical field [0001] The invention belongs to the field of power quality, and in particular relates to a method for collecting power quality data of power users based on economic evaluation. Background technique [0002] With the rapid development of society, people have higher and higher requirements for power supply. Power disturbances may cause industrial users' equipment to stop running, operate unsteadily or make mistakes, reduce efficiency or shorten life, etc., and then affect (or completely interrupt) the production process or service activities, resulting in economic losses. With the complexity of industrial loads and the improvement of user demand levels, the importance of power quality in demand-side management has become increasingly prominent. Power quality may cause user equipment outage, operation error, efficiency reduction or life shortening, etc., which will bring huge economic costs to users and greatly affect the effective and economical utilization of...
