Solar power generation high-voltage direct-current centralized-power-supply LED street lamp system

Abstract

The invention provides a solar power generation high-voltage direct-current centralized-power-supply LED street lamp system, which includes an LED single lamp module, a DC bus, an AC bus, a solar power grid-connected inversion device, and a high-voltage direct-current centralized-power-supply device. The LED single lamp module includes a solar cell panel, an LED street lamp, and an intelligent single lamp controller. The solar cell panel generates electricity via the intelligent single lamp controller, the DC bus, and the solar power grid-connected inversion device. The high-voltage direct-current device provides a high-voltage direct-current power source for an LED street lamp via the DC bus. The street lamp system related in the invention can generate electricity; one two-core cable is shared in power generation of the solar cell plate and high-voltage direct-current power supply; and the investment cost of the street lamp system is reduced. Furthermore, the street lamp system ensures the light-lamp rate via high-voltage direct-current power supply.

Description

technical field [0001] The invention relates to the field of street lamp design, in particular to an LED street lamp system for solar power generation high voltage direct current centralized power supply. Background technique [0002] The current LED street lamp system adopts the technology of three-phase four-wire AC power supply, single lamp and single power supply. Most street lamp cables use 5-core cables, which account for more than 30% of the investment cost of street lamp systems. [0003] However, the current solar street light system is limited by expensive batteries with limited lifespan, and the application cost is high; at the same time, in order to ensure the lighting rate in rainy weather, the capacity of solar panels and batteries are equipped with high capacity, and the resource utilization rate is usually low, resulting in It is a big waste, and it is still difficult to guarantee the lighting rate in extreme weather. [0004] The current street lamp depart...
