A method for grid-connected power generation based on solar street lamp power supply system

Abstract

The invention discloses a method for grid-connected power generation based on a solar street lamp power supply system, and the method comprises the following steps: street lamp grouping, primary rectification, DC output, secondary rectification, waveform adjustment, and grid-connected power generation. The method can be used for the centralized management of solar street lamps for urban lighting; can enable residual power to be safely and effectively inputted into a national power grid while meeting street lamp illumination; irons out defects that conventional solar street lamp generation is small in application range, cannot meet the industrial and lift power utilization demands and cannot meet the requirements of large area and remote power supply; improves the comprehensive utilization rate of solar street lamp power generation, reduces the utilization cost of solar street lamp power generation, and facilitates the alleviation of urban power supply.

Description

technical field [0001] The invention relates to a grid-connected power generation method based on a solar street lamp power supply system, which belongs to the technical field of grid-connected power generation. Background technique [0002] At present, in the national power grid, three sine wave alternating currents are the main power supply methods. However, with the advancement of solar power generation technology, the shortage of power supply in the national grid and the strengthening of people's awareness of environmental protection, on the one hand, in order to meet the needs of urban night lighting, on the other hand On the one hand, in order to reduce the pressure on urban power supply, solar street lighting systems have been widely promoted and used. With the increase in the number of solar street lights used, the total amount of solar power generation has also increased rapidly, and has become an important source of urban power supply. Its power supply potential is...

[0002] At present, in the national power grid, three sine wave alternating currents are the main power supply methods. However, with the advancement of solar power generation technology, the shortage of power supply in the national grid and the strengthening of people's awareness of environmental protection, on the one hand, in order to meet the needs of urban night lighting, on the other hand On the one hand, in order to reduce the pressure on urban power supply, solar street lighting systems have been widely promoted and used. With the increase in the number of solar street lights used, the total amount of solar power generation has also increased rapidly, and has become an important source of urban power supply. Its power supply potential is huge, but because the distribution of solar street lights is relatively loose, and the electricity generated is all direct current, it is difficult for a single solar street light to effectively meet the needs of industrial and domestic electricity consumption, although multiple solar street lights can be used for joint power supply , but because the power generated by solar street lamps is direct current, it still cannot directly meet the needs of most electrical equipment, and the current technology cannot realize long-distance transmission of low-voltage direct current. Therefore, it greatly limits the power supply potential of the solar street lamp system.
