An Intelligent Processing Method for Power Supply Quality Control of Electricity Distribution Networks

Abstract

With the continuous increase of high-power loads such as residential air conditioning and floor heating, the resulting load fluctuations and serious problems of voltage reduction at the end of the distribution lines have become increasingly prominent, which brings great challenges to the operation control and power quality management of power supply utilities. There need to be more intelligent, convenient, and effective solutions. This paper proposes an intelligent control scheme for power supply quality control of electricity distribution networks to solve this problem. A complete set of control devices are also designed in this paper. Multiple monitoring devices are installed on low-voltage distribution networks. This realizes effective monitoring of abnormal voltage data in the distribution network and compensates for the shortage of monitoring equipment in the low-voltage distribution network. Through the design of an intelligent two-way AC contactor, the alternative power supply can be automatically switched after equipment failure to achieve automatic voltage regulation. The intelligent and reliable system voltage regulation is realized by combining voltage regulation of transformer on-load tap changer, line reactive capacitors, and standby power supply. This scheme can save labor costs, ensures power supply quality and reliability of the distribution network, and has potential significance for improving power supply quality at the end of distribution lines.
