A load monitoring device for power system

Abstract

The present invention provides a load monitoring device for power system, including a voltage sensor, a current sensor, a pre-processing chip, a single-chip microcomputer and a processing unit, the output end of the voltage sensor is connected to the input end of the pre-processing chip, the current sensor The output end of the preprocessing chip is connected with the input end of the preprocessing chip, the output end of the preprocessing chip is connected with the input end of the single-chip microcomputer, and the output end of the single chip microcomputer is connected with the input end of the processing unit; the present invention has the following beneficial effects: by The powerful computing and processing capabilities of the data processing module, high-speed computing to obtain the load status of the power system components, and automatically judge the power consumption mode and behavior of the circuit user in general and the power consumption mode and behavior of the circuit user in special circumstances The mapping rules between them can obtain the load status of the power system components under real conditions, and the load status can be transmitted to the Ethernet in time through the communication module, which is convenient for the staff to monitor.

Description

technical field [0001] The invention is a load monitoring device used in an electric power system, which belongs to the field of electric power. Background technique [0002] Load management refers to the improvement of users' electricity consumption behavior and electricity consumption mode through load adjustment technology, so as to reduce the maximum load of the power grid, achieve energy saving, reduce system installed capacity, and reduce power investment and operating costs. For example, the implementation of valley peak electricity price And tiered electricity prices to encourage users to avoid peak periods of electricity consumption. [0003] Load management is user-oriented, with the help of various economic and technical means, while ensuring the reliability of the power network, changing the shape of the system load curve to achieve different load management objectives, so as to serve the safe and economical operation of the power system. Generally, there are si...
