Abstract

A DC / AC hybrid and off-grid energy rout device is disclosed, It mainly consists of distributed power interface, bidirectional AC power interface, unidirectional DC power output interface, sensor signal interface, energy storage battery interface, unidirectional AC power output interface, energy router control module, energy meter (10, 16), grid-connected transfer switch, off-grid transfer switch,multi-MPPT-DC / DC module, bidirectional DC / AC module, A switch power supply / rectifier module is compose of, in accordance with that signal interface of the sensor, distributed power interface, Data transmitted by the energy storage battery interface, Through the detection and control of the unidirectional DC power output interface and the bidirectional AC power connection interface by the energy router control module, the multi-path AC / DC hybrid off-grid active power supply and distribution for different loads and different periods is realized, the structure of the micro-grid is optimized, andthe clean energy access ratio and the active distribution capacity are improved.

Description

technical field [0001] This patent is an AC / DC hybrid and off-grid energy router device, which is suitable for a micro-grid composite power supply system with AC / DC hybrid power supply. For example, for communication base stations with existing mains power supply, it can realize multi-path AC and DC hybrid and off-grid active power supply and distribution with different loads and different time periods with the mains AC bus and the internal DC bus of the base station. Background technique [0002] An energy router used in electric energy occasions, also known as an electric energy router, refers to a device that can realize multi-directional flow of energy and active control of power flow; as a distributed power supply, reactive power compensation equipment, The intelligent interfaces of energy storage devices and loads should flexibly manage the dynamic power within the regional power grid and the entire distribution network under the premise of ensuring power quality. The...
