Problems solved by technology

In the building, the wiring specification based on (green power supply) DC is not considered. Even if some electrical equipment adopts DC power supply, it must be powered by a separate transformer rectifier regulator and connected with an external dedicated wire.

Description

technical field [0001] The invention relates to a power supply system, in particular to an intelligent power supply system with solar energy as the main power supply. Background technique [0002] At present, most of the solar power generation systems are large-scale power stations, which are relatively expensive, and basically rely on national policy subsidies to survive. my country's current power generation and power supply system is dominated by black energy—large-scale AC power grids, supplemented by green energy (solar power, etc.). Solar power generation is to convert sunlight into electrical energy (low-voltage DC power) through photovoltaic cells. In order to be able to incorporate it into the AC grid, the DC power must first be converted into AC power (frequency 50Hz) through an inverter, and then boosted through a transformer. In order to stabilize the voltage and adjust the stable phase through special equipment, it can be synchronized with the grid, that is, gr...
