It waits, is generated electricity using the air wind driven generator of high-pressure gas device storage, obtained electricity is sent in load winding.
The output winding of the wind-driven generator is connected with ad/da converter, and the ac input end of the ad/da converter connects
The wind-driven generator, the ac output end of the ad/da converter are connected in the load winding.
Since the voltage of the electric energy of wind-driven generator production is extremely unstable in said program, so needing ad/da converter
The electric energy that wind-driven generator produces is become into stable and identical with load winding voltage, is then connected in load winding.
The load winding is connected with the decision mechanism of monitoring load power consumption, and the output terminal of the decision mechanism is connected with control
System switch, control switch are serially connected in the current supply circuit of the air compressor.
In said program, when loading power consumption less than setting value, the decision mechanism is by controlling switch connection air
The current supply circuit of compressor；When loading power consumption higher than setting value, the decision mechanism, which passes through to control to switch, disconnects air pressure
The current supply circuit of contracting machine.
The output terminal of the decision mechanism is also associated with valve, which is located on the ventilating duct.
When connecting the current supply circuit of air compressor, closed by decision mechanism control valve；Disconnect air compressor
During current supply circuit, opened by decision mechanism control valve.
By controlling above-mentioned valve that wind-driven generator is made to work or stop, can also tune be reached by valve regulated wind speed
Save wind turbine power generation voltage.
The beneficial effects of the utility model：Substation need not expand can, in low power consumption, with regard to high pressure can be converted electrical energy into
Interior energy, and store, avoid waste of energy；Interior energy is converted to electric energy, and electric energy is connected to the grid by peak of power consumption, meets peak
Overload power utilization demand.
