Control cabinet for digital current transformation transmission and current conversion distribution based on direct-current power supply

Abstract

The invention relates to a control cabinet for digital variable-current transmission and commutation power distribution based on a direct-current power supply, which is characterized in that the direct-current power supply of a multi-energy complementary centralized power generation field charges and stores energy to DC1, DC2, DC3 and DCn storage battery packs (1) through a confluence energy storage and protection device (2); the energy management matrix machine (3) is used for managing and supplying a direct-current power supply to the direct-current power supply conversion module (4) and the power supply conversion and transmission processor assembly (5) according to a time sequence and presetting an operation control mode of the direct-current power supply conversion module (4); comprising the following steps: starting a vacuum circuit breaker M1 to drive a motor (22) to close an intelligent GK1 vacuum circuit breaker (19), connecting an alternating current power supply output by a direct current power supply conversion module (4) to an intelligent high-voltage protection device (20) and a boost autotransformer (21), and outputting a higher-grade high-voltage power supply; a vacuum circuit breaker M2 is started to drive a motor (26) to close an intelligent GK2 vacuum circuit breaker (27), and the intelligent GK2 vacuum circuit breaker (27) is connected to a commutation power distribution device (31) to distribute power to an intelligent micro-grid.

Description

technical field [0001] The invention relates to the field of "a control cabinet for digital variable current transmission and power conversion distribution based on DC power supply", which solves the dilemma of using multi-energy complementary new energy as the main energy source and prioritizing energy consumption. Background technique [0002] Most of the existing off-grid inverter technologies are UPS power supplies. Its disadvantages are: the off-grid inverter's energy storage and conversion technology is simple and its power is limited, and its output power is limited to the power consumption of a single load on site for a limited time, and it is not suitable to send it out. Contents of the invention [0003] In order to overcome the above-mentioned defects, the present invention provides "a control cabinet based on digital variable current transmission and commutation power distribution based on DC power supply", which changes the technical method of power conversion...
