An Electricity Information Acquisition System with Surplus Current Monitoring Function

Abstract

An electricity consumption information collection system with residual current monitoring function, including the main station level, the general protection level on the low-voltage side of the distribution station area, and the intermediate protection level between the general protection level and users. The main station level has interconnection The front-end computer and server; the general protection level has a first-level residual current action protector and a public transformer terminal, and the intermediate level has a second-level residual current action protector, and the second-level residual current action The residual current information and operating status information are transmitted to the public transformer acquisition terminal, and the first-stage residual current action protector transmits the residual current information and operating status information to the public transformer collection terminal through the 485 bus, and the public transformer collection terminal communicates with the front-end computer , which is used to upload the collected residual current information and operating status information to the server, and can receive and forward the server’s control instructions to control the action of the first and second level residual current operated protectors.

Description

technical field [0001] The invention relates to a power consumption information collection system. Background technique [0002] The power consumption information collection system of power users is a system for collecting, processing and real-time monitoring of power consumption information of power users, realizing automatic collection of power consumption information, abnormal measurement monitoring, power quality monitoring, power consumption analysis and management, and related information release , distributed energy monitoring, information interaction of intelligent electrical equipment and other functions. At present, power supply enterprises have established a complete electricity consumption information collection system, installed and used various intelligent terminals such as electricity consumption information collection terminals and smart meters, and realized the voltage and current of power users by using modern wireless data communication technology and comp...

AI Technical Summary

Problems solved by technology

However, the residual current in the distribution station area, which is an important data for electricity safety, has not been collected in a centralized and automatic manner. The installation rate, commissioning rate and operation status of protectors cannot realize comprehensive remote automatic monitoring and management
