Distributed new energy direct-current power supply device system

Abstract

The invention discloses a distributed new energy direct-current power supply device system, and relates to the technical field of direct-current power supply. The system is formed by connecting new energy, an accumulator, a direct-current load, a selector switch, an inverter, a rectifier, an electric quantity metering device, a grid-connected control device and a public power grid. The new energyis a solar power generation device and a wind power generation device with direct-current output. The accumulator is a battery, a capacitor, a super capacitor or a graphene super capacitor. The direct-current load is a refrigerator, an air conditioner, a washing machine and an alternating-current and direct-current dual-purpose electric appliance based on direct-current frequency conversion. The invention discloses a distributed new energy direct-current power supply device system based on development opportunity of a 'distributed+energy storage' technology and development of technologies of refrigerators, air conditioners, washing machines and alternating-current and direct-current dual-purpose electric appliances based on direct-current frequency conversion. According to different powersupply actual conditions, modular configuration, fixation or movement and other modes are implemented, and a new technical material basis is provided for improving the utilization efficiency of new energy and reducing energy consumption and product cost.

Description

technical field [0001] The invention relates to the technical field of DC power supply, in particular to a distributed new energy DC power supply device system. Background technique [0002] If solar photovoltaics wants to enter every aspect of life, it must cooperate with home appliance companies to develop civilian products. The research and development and production of solar electrical appliances undoubtedly provide the possibility for low-carbon environmental protection, energy saving, emission reduction, and cost reduction. At the same time, it is also a breakthrough in the home appliance industry. important opportunity. [0003] According to the forecast of the International Energy Agency, photovoltaics will gradually become the cheapest way of generating electricity by 2030. The overall prosperity of photovoltaics depends on distributed power generation. Distributed energy technology is an important development direction of the world's energy technology in the ...
