Acquisition and Control system for electricity utilization information of electricity consumers

Abstract

The invention provides an acquisition and control system for electricity utilization information of electricity consumers. The acquisition and control system comprises loading control devices, electricity quality monitoring devices, control switches and electricity meters which are arranged at various electricity consumer ends, as well as an electric loading monitoring center arranged at the remote end, wherein each loading control device is provided with a first GPRS communication module; the loading control devices are in communication with the electric loading monitoring center via a GPRS network through the first GPRS communication modules; each loading control device is in electric connection with the corresponding control switch and a signal of the corresponding electricity meter. The control system has the structural characteristics that each loading control device is in electric connection with a serial communication port signal of the corresponding electricity quality monitoring device; the electricity quality monitoring device and the corresponding loading control device at the same electricity consumer end share a communication link, or the electricity quality monitoring device is controlled by the corresponding loading control device to be in communication with the electric loading monitoring center. The control system can reduce the communication operation cost of an electricity supply department, and improves accuracy and timeliness when electricity failure or electricity limitation is carried out during abnormal electricity utilization.

Description

technical field [0001] The invention relates to a system for collecting and controlling electricity consumption information of electric power users. Background technique [0002] At present, the power consumption information collection and control system of power users has been widely used in the power supply department. The structural block diagram of the power user information collection and control system currently used is as follows: figure 1 As shown, it is mainly composed of load control devices, power quality monitoring devices (PQMD), control switches, meters, and a power load monitoring center set at the remote end (usually in the power supply management department) installed on each user terminal side. The load control device is provided with a first GPRS communication module; the power quality monitoring device is provided with a second GPRS communication module. The current operating mode of the electricity consumption information collection and control system ...

AI Technical Summary

Problems solved by technology

[0003] In the current electricity consumption information collection and control system for power users, the load control device and power quality monitoring device of each user terminal are respectively connected through a GPRS communication link, that is, one user terminal adopts dual GPRS communication links and remote power load monitoring. Central communication; its disadvantages are: First, due to the large number of current power users, at the same time, a large number of power quality monitoring devices need to maintain online communication with the power load monitoring center, coupled with the instability of the network , which makes it very difficult for the power load monitoring center to collect the power quality information of all users in real time, completely and reliably; second, the power quality parameters of all users are calculated by the power load monitoring center and judge whether there is an abnormality, so that the power load The monitoring center is overwhelmed; the third is that when a certain client has abnormal power consumption, it needs to upload data through the power quality monitoring device of the client, and after the power load monitoring center calculates and processes the abnormal data, it sends a report to the load control device of the client. Control commands and other links, so that the response time from the client to the client's load control device is prolonged when the client detects abnormal electricity consumption, resulting in the problem of untimely processing; Fourth, the GPRS business of the communication department is billed according to the flow rate, and the dual GPRS communication link way to increase the operating costs of the utility
