Building harmonic compensation method, terminal equipment and storage medium

Abstract

The invention relates to a building harmonic compensation method, terminal equipment and a storage medium. The method comprises the steps: setting a centralized compensation module on a centralized power supply end line of a building, setting a local compensation module on a line of each room, and setting compensation controllers, used for controlling whether the corresponding compensation modules conduct compensation or not, on the centralized power supply end line and the line of each room; collecting the harmonic content of each line through the compensation controllers; when the harmonic content of the line of the centralized power supply end is smaller than a set harmonic threshold value, enabling the compensation controller to control the centralized compensation module to stop harmonic compensation, and otherwise, enabling the compensation controller to control the centralized compensation module to perform harmonic compensation; enabling the compensation controller on the line of each room to control whether the local compensation modules to perform harmonic compensation or not according to the harmonic contents on the lines where the compensation controllers are located. Full-automatic control over harmonic compensation is achieved, and energy consumption and manpower input in the aspects of management, operation and maintenance are reduced.

Description

technical field [0001] The invention relates to the technical field of harmonic detection, in particular to a building harmonic compensation method, terminal equipment and a storage medium. Background technique [0002] With the development of science and technology and economy, various types of electricity demand have higher and higher standards for power quality. If the long-term use of electric energy deviates from the index, it will cause serious consequences such as equipment damage, power efficiency decline, and economic losses. Therefore, Harmonic control is an essential part of today's power system. Under the needs of users, more and more non-linear devices such as energy-saving lamps, TVs, computers, and switchgears are inevitably connected to the building power system. These devices will be used as harmonic sources in the power grid to generate Harmonic pollution affects power quality. [0003] Building harmonics will greatly affect the power efficiency and power...

Problems solved by technology

However, usually because of the different loads in different time periods, the amount of harmonics contained in the line voltage will also be different. The centralized filter configured in the power distribution room of the building may not be able to meet the harmonic filtering accuracy requirements of all time periods. In some Although the time period can achieve a certain harmonic suppression benefit, it cannot meet the requirements of the public power grid for power quality

[0004] In the traditional system, facing the changing harmonic environment within a day, the manpower invested in supervision is a big problem. First of all, the accuracy and response time of manual operation cannot be compared with program control, and long-term work may appear slow. Operation or even misoperation will cause the power quality to decline, and in severe cases, it will even lead to the reduction of equipment life and damage
