Photovoltaic power generation common-network anti-backflow heat storage control device and method based on remote control

Abstract

The invention relates to a photovoltaic power generation common-network anti-reflux heat energy storage control device and method based on remote control. The control device comprises a heat energy storage main controller module, a driving module connected with the controller module, a touch screen serving as a human-computer interaction display control interface and a GPRS communication module for viewing and detecting dynamic conditions in a networking manner, wherein the main control module drives an H bridge consisting of IGBT in the driving module by controlling a CPLD chip to generate PWM time sequence so as to output direct current for heating a heat energy device. According to the method, the micro-grid system of the power network of small-sized factories and home users shared by solar photovoltaic power generation and commercial power is used in the occasions with fixed hot water demand time, relevant electric quantity is detected, analysis guarantees that no redundant electric quantity flows into the commercial power on the premise of utilizing the solar photovoltaic power generation to the maximum extent, troubles of a large amount of wiring are omitted, and the clean energy heat energy storage device is heated, so that reverse current is prevented from being generated.

Description

technical field [0001] The present invention relates to the technical field of anti-backflow control, in particular to a control device and method for anti-backflow thermal energy storage based on remote control photovoltaic power generation common network. Background technique [0002] Part of the existing technology is to control the conduction or shutdown of the switch circuit through the logic control circuit of the electrical component to achieve the purpose of controlling the anti-backflow; the other part is to monitor the current and voltage of the network side through the voltage and current measurement and control instrument Sending excess electric energy into the grid and taking remedial measures to prevent backflow when excess electric energy enters the grid is an after-the-fact remedy. And the online performance is not well considered, and the network expansion function is lacking. [0003] The existing anti-backflow technology is to detect the voltage and curre...
