Problems solved by technology

The current output by the wind turbine is rectified by the wind turbine controller and then directly connected to the busbar of the battery. When the output voltage of the wind turbine is low, the wind turbine cannot be separated from the battery, so that the battery feeds back current to the wind turbine. Complementary solar powered systems cause serious damage

Embodiment 1

[0014] A wind-solar complementary solar power supply system, such as figure 1 As shown, it includes: solar panel, fan system, fan input board, solar controller, storage battery. It is used to control the power generation status of the solar panel, control the charging and discharging of the battery, control the opening and closing of the load power supply circuit of the wind-solar complementary solar power supply system, and collect the voltage and current of the battery; the output circuit of the fan controller is passed through The fan input board is connected to the solar controller; when the output voltage of the fan controller is lower than the battery voltage, the fan input board automatically cuts off the current loop of the wind generator.

[0015] Through the additional fan input board, when the output voltage of the wind generator is lower than the battery voltage, the wind generator can be disconnected from the battery, so as to avoid serious damage to the wind-sola...

Embodiment 2

[0017] Wind-solar complementary solar power supply system, such as figure 1 , figure 2 , including: 4 solar panels (U1, U2, U3, U4), two fan systems, solar controllers, two batteries B1, B2, the fan system includes a wind generator, and the AC output of the wind generator is sorted into DC The fan controller; the solar controller is respectively connected with the power input board of the solar panel and the batteries B1 and B2.

Abstract

The invention provides a wind-solar compensation type solar energy power supply system which comprises a solar cell panel, a fan system, a solar energy controller, a storage battery, a fan controller and a fan input board of the solar energy controller, wherein the fan system comprises a wind driven generator and a fan controller which rectifies alternating current output by the wind driven generator into direct current; the solar energy controller is respectively connected with the solar-cell panel and the storage battery and used for controlling the power generating state of solar-cell panel and the charging and discharging of the storage battery as well as controlling the wind-solar compensation type solar energy power supply system to load the on and off of a power supply loop and acquire the voltage and the current of the storage battery; the fan input board is used for automatically switching off the current loop of the wind driven generator when the output voltage of the fan controller is lower than storage battery voltage so as to prevent the storage battery from back sinking current to the wind driven generator and avoid the serious damage to the wind-solar compensation type solar energy power supply system.

Description

【Technical field】 [0001] The invention relates to a hybrid power supply system, in particular to a wind-solar complementary solar power supply system. 【Background technique】 [0002] In recent years, with the urgent demand for natural energy applications in various countries, more and more solar energy and wind energy have been extended to various fields, and wind-solar complementary solar power supply systems have emerged as the times require. The wind-solar complementary solar power supply system is composed of solar panels, fan systems, solar controllers, and batteries. The wind turbine system includes a wind turbine and a wind turbine controller. The solar controller is used to control the solar panel, control the charging and discharging of the battery, and control the opening and closing of the current output of the system. The current output by the wind turbine is rectified by the wind turbine controller and then directly connected to the busbar of the battery. When...
