Method for monitoring voltage quality

Abstract

The invention relates to a method for monitoring voltage quality. The method comprises the following steps of: firstly acquiring voltage quality data of various voltage grades in a regional power grid, analyzing and judging a power supply voltage quality index by analyzing the data and using different measures, and providing a corresponding adjusting scheme. According to the invention, the data relevant to the voltage quality and other auxiliary real-time date in the whole regional grid are comprehensively collected and used, so that aims of comprehensive analysis, judgment and management at an overall information processing level are fulfilled; and the voltage quality is reasonably and effectively monitored according to overall situation and consideration and through deep date mining from points to surfaces. According to the analysis and judgment flow of the method, an open decision support library, a fixed analysis model and an artificial intelligence model structure are provided, and the uniform analysis and individual analysis are combined, so that the method is applicable to adaptability analysis occasions.

Description

Technical field: [0001] The invention relates to the field of voltage quality control, in particular to a voltage quality monitoring method. Background technique: [0002] With the improvement of rural economic level, the development of rural urbanization and industrialization, especially the problem of voltage quality, which is dominated by the phenomenon of "low voltage", has become a common problem and needs to be solved systematically. Although the power company has continuously invested a lot of manpower and material resources to improve the voltage quality level of the entire power grid to a new level, especially the high-level backbone network. But for power grids in remote areas, voltage quality has always been an unsolved problem. [0003] At present, in the planning, design, construction, production and maintenance of the power grid, various technical management methods have been tried to solve the voltage quality problem, mainly including the following aspects: u...

At the same time, for systemic problems, some areas also conduct special voltage quality monitoring by configuring voltage monitors with wireless upload functions, harmonic monitoring devices, etc. As a result, the system is in an isolated and partial monitoring state, and there is no organic integration of relevant voltage quality monitoring data and information in other existing automation systems in the entire regional distribution network for comprehensive analysis and joint control to form a unified voltage quality decision support. The purpose of voltage quality monitoring and decision support for the entire regional distribution network
