Wind and solar mutual compensating system for greenhouse

Abstract

The invention discloses a wind and solar energy mutual compensating system for a greenhouse. The wind and solar mutual compensating system comprises a wind power device, an optoelectronic device, a storage battery and a wind and solar mutual compensating controller. In the system, output parameters of the wind power device and the optoelectronic device are detected and then inputted in the wind and solar mutual compensating controller to be processed; an electronic switch is controlled to be turned on or turned off according to the processing result and the energy demand of the greenhouse; and finally, any one of the wind power device, the optoelectronic device or the battery is chosen to supply power to the greenhouse. The system realizes the complex utilization of the wind and the solar; the wind and solar mutual compensating system also effectively increases the sufficient energy proportion of the greenhouse and the utilization rate of green energy; and at the same time, the application field of the field greenhouse is expanded.

Description

Technical field [0001] The invention belongs to the field of energy supply for greenhouses, and its outstanding feature is that it can comprehensively and efficiently utilize local wind energy and light energy, and synergistically provide energy for electric equipment in the greenhouse. Background technique [0002] At present, a single greenhouse system powered by wind power and photovoltaics has the application of providing electric energy for the greenhouse. Its advantages are relatively low cost and simple system structure, but its disadvantages are also obvious, that is, in general, a single wind energy or It is because the photovoltaic power generation equipment cannot always have sufficient energy input, that is to say, the energy supply system works for a relatively high proportion of time under the condition of insufficient input energy, so that the greenhouse is in a situation of no power supply or insufficient power supply Down. At the same time, the single energ...
