Electricity management terminal with power factor compensation function

Abstract

The invention relates to an electricity management terminal with power factor compensation function, which comprises a power supply unit for supplying power, a sampling unit for receiving real-time voltage signals and current signals on phase lines and a processing unit for performing data processing by using the voltage signals, the current signals and received control information of at least one electricity management unit and outputting corresponding control signals, wherein the data processing at least comprises the steps of calculating consumed electric energy value, active power, passive power and power factor value and outputting a power factor compensation control signal when the power factor value is not within a preset threshold range.

Description

technical field [0001] The present invention relates to a power consumption management terminal, in particular to a power consumption management terminal with a power factor compensation function. Background technique [0002] With the development of the economy, the dependence of various fields of the national economy on electric energy continues to increase. In order to measure the amount of electricity consumption and realize effective management of the electricity consumption site, power metering equipment has emerged as the times require, and has become an important part of the field of electric power technology. A hot direction of continuous innovation. [0003] Chinese patent application 200610132328.4, named as a load control and multi-channel time-sharing charging electric energy composite management system, which includes a main control module, a data acquisition module, a time module, a meter reading module, an execution module, a display module, a communication m...
