Problems solved by technology

Although this method is effective, on the one hand, the fan is still running at high speed, and continuing to charge will affect the life and safety of the wind turbine; on the other hand, the unloader is a DC load and a heat source, causing new inconveniences to users security factor, not a good practice

Embodiment Construction

[0017] The present invention will be further described below in conjunction with accompanying drawing.

[0018] Such as figure 2 As shown, the low-power electromagnetic deceleration and pressure-limiting wind-solar hybrid power generation system includes at least one wind power generator, at least one solar power generation component, an intelligent controller, a storage battery, and an inverter connected to an AC load. The wind power generation After the machine is rectified, it is connected in parallel with the solar power generation component, and is connected with the battery and the inverter through an intelligent controller. Connect with the intelligent controller; when the speed of the wind turbine exceeds the speed limit or the voltage of the battery exceeds the limit value, the intelligent controller sends an instruction to turn on the switch circuit, the electromagnetic eddy current reducer works, and the current generated by the wind turbine is fed back to the magn...

Abstract

The present invention relates to a small power electro-magnetism decelerate pressure-limiting scenery complementary power generation system, which adds a electro-magnetism backset decelerator on the basis of original power generation system, the decelerator is coaxially set the axis of the rotor of a wind power generator, and connects with a intelligent controller through a on-off circuit. The present invention adds a set of electro-magnetism backset decelerator on the basis of the power generation system, and realizes automatic deceleration through automatic control of a intelligent controller when a blower fan over speeds, or automatic pressure limitation when a accumulator cell over charges, to make rotate speed of a power generator and pressure of the accumulator cell never beyond the setting value whatever conditions the wind motor in, so as to keep it in secure and dependable working status always.

Description

technical field [0001] The invention relates to a power generation system, in particular to a low-power electromagnetic deceleration and pressure-limiting type wind-solar complementary power generation system. Background technique [0002] Such as figure 1 , the speed of the small wind turbine is proportional to the wind speed, the higher the wind speed, the faster the speed, and the output voltage of the wind turbine is proportional to the speed of the wind turbine, the faster the speed, the higher the voltage. [0003] Because the speed of conventional small wind turbines cannot be controlled timely and accurately, the output voltage of wind turbines varies greatly, sometimes far exceeding the allowable voltage range. Moreover, when the battery is overcharged, the working wind turbine cannot adjust its working state, which seriously affects the reliability and safety of the system. Some systems increase the DC discharge load for voltage control. On the one hand, the wind...
