A method for power grid-connected power generation based on wind-solar integrated power generation circuit lights

Abstract

The invention discloses a wind and light integrated power generation street lamp-based power supply power grid-connected power generation method. The method includes the steps of street lamp grouping, direct current output, primary rectification, secondary rectification, waveform adjustment, grid-connected power generation and the like. With the wind and light integrated power generation street lamp-based power supply power grid-connected power generation method of the invention adopted, wind and light-integrated street lamps for urban lighting can be managed in a centralized manner; when the lighting of the street lamps is realized, excess electricity can be incorporated into a national power grid safely and effectively; the defect of incapability of satisfying requirements of industrial and domestic electricity utilization and realizing large-area and long-distance power supply caused by the narrow application range of traditional wind and light integrated power generation can be eliminated; and the comprehensive utilization rate of wind and light integrated street lamp power generation can be improved, the use cost of the wind and light integrated street lamp power generation can be reduced, and alleviation of urban power supply stress can be facilitated.

Description

technical field [0001] The invention relates to a grid-connected power generation method for a power supply grid based on a wind-solar integrated power generation circuit lamp, and belongs to the technical field of grid-connected power generation.

[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.
