Independent wind power generating protection apparatus

Abstract

The invention discloses an independent wind power generating protection apparatus. The apparatus comprises a PSoC controller, a wind turbine generator system used for converting wind energy into electric energy and a storage battery used for storing superfluous electric energy converted from wind power. The input end of the PSoC controller is connected with a keyboard input circuit, a wind speed acquisition sensor, a first voltage acquisition circuit and a second voltage acquisition circuit, and the output end of the PSoC controller is connected with a liquid crystal display circuit, a first transistor switch circuit and a second transistor switch circuit; and the output end of the wind turbine generator system is successively connected with a surge protection electric power part, a power conversion circuit, a DC / DC conversion circuit, the first transistor switch circuit, the storage battery, the second transistor switch circuit, a DC / AC conversion circuit and a second load circuit, and the output end of the DC / DC conversion circuit is connected with a first load circuit. The independent wind power generating protection apparatus has the advantages of novel design, simple structure, high overcurrent protection and high practicality.

Description

technical field [0001] The invention belongs to the technical field of wind power generation, and in particular relates to an independent wind power generation protection device. Background technique [0002] The continuous development of society, environmental protection, the development of new energy sources, and low-carbon life are all the problems we are facing today. In response to the call, we will vigorously develop wind power generation, convert wind energy into electrical energy, and store the electrical energy in batteries to supply loads. , using a single-chip microcomputer to control the charge and discharge state of the battery to maximize efficiency, the random fluctuation of wind speed and the nonlinearity of wind power conversion efficiency of wind turbines make the wind power fluctuate violently, and the user's power demand is also time-varying, which makes the independent The severe mismatch between supply and demand of wind power system will easily lead to...

Problems solved by technology

Because wind power generation is located in a desolate and uninhabited area, the environment is relatively harsh. In addition, because it is outdoors and faced with thunderstorms, it has a great impact on wind power generation. Therefore, the current market lacks a protection device that can protect wind power generation against lightning weather, avoid lightning and large current breakdown damage, and minimize losses. To develop such protectors, very valuable
