Abstract

When multiple paths of photovoltaic cells or wind generators are connected to a grid through a junction box, the output voltage and current are different due to the effects of the properties of various photovoltaic cells or wind generators and the environmental factors. The reflux phenomenon is generated during collection due to the relatively great difference to cause a partial short-circuit. Aiming at the factor, the invention provides a constant-flow and constant-voltage discharge buffering and collecting system employing capacitors and charge and discharge modules. The traditional inverted grid-connected mode is changed; a lead-acid storage battery which is relatively short in service life and pollutes the environment is abandoned; clean energy is utilized to the maximal extent; and meanwhile, the defect of partial short circuits of the photovoltaic cells or the wind generators, which output relatively low voltage when anti-inverted diode is utilized is avoided.

Description

technical field [0001] The invention relates to a solar or wind power generation system, in particular to an independent solar or wind power generation capacitive buffering and confluence system. Background technique [0002] When multiple photovoltaic cells or wind motors are connected to the grid through a combiner box, due to the nature of each photovoltaic cell or wind motor and the influence of environmental factors, there are differences in the output voltage and current. When this gap is large, it will lead to backflow phenomenon when converging, resulting in local short circuit. Contents of the invention [0003] The present invention aims at this factor and provides a constant current and constant voltage discharge buffer confluence system using a capacitor and a charging and discharging module. [0004] The technical solution of the present invention is to construct an independent solar or wind energy generating capacitive buffer confluence system, including pho...
