Fig. 1 is the structural representation of the utility model electric power supply control system;
Among the figure: 1. wind-driven generator; 2. net electric module; 3. boost pressure controller; 4. off-load resistance box; 5. the complementary control cubicle of wind-powered electricity generation net electricity; 6. oil pumper variable frequency control cabinet; 7. oil pumper.
Embodiment
Describe the utility model in detail below in conjunction with accompanying drawing 1.
Referring to shown in Figure 1, the described electric power supply control system of the application comprises wind-driven generator 1, nets electric module 2, boost pressure controller 3, off-load resistance box 4, the complementary control cubicle 5 of wind-powered electricity generation net electricity.Boost pressure controller 3 is connected with wind-driven generator 1, off-load resistance box 4, the output of boost pressure controller 3 and the complementary control cubicle 5 of the electric module 2 access wind-powered electricity generation net electricity in parallel of net.Boost pressure controller 3 inner rectification modules will be direct current from the AC rectification of wind-driven generator 1, and its voltage clamped down at DC550V all the time by boost pressure controller 3, to system's rear end output voltage stabilization is the direct current of DC550V, during even wind-driven generator is in like this under the low wind speed, wind power hour also can guarantee the voltage of constant output.After boost pressure controller 3 will boost from the wind-powered electricity generation rectification of wind-driven generator, the constant voltage of output DC550V is to the complementary control cubicle 5 of wind-powered electricity generation net electricity, the complementary control cubicle 5 of wind-powered electricity generation net electricity links to each other with the electric module 2 of net simultaneously, its by rectification module with the net electric rectification, and and rectification after wind-powered electricity generation voltage connecting system in parallel simultaneously, and the net after rectification electricity and wind-powered electricity generation voltage compared, different according to the voltage height, select high-voltage power supply preferentially to the rear end electric.Because voltage is about about DC520V after the rectification of the electric module of net, and the voltage of wind-powered electricity generation is DC550V, so when wind-driven generator turns round, be that the voltage of wind-powered electricity generation is raised to the voltage that is higher than the net electricity, when the wind-powered electricity generation brake is not generated electricity, the voltage of net electricity just exceeds wind-powered electricity generation voltage naturally, this moment, system adopted the net piezoelectric voltage to electric, therefore realize that the preferential wind power generation that uses is to oil pumper variable frequency control cabinet 6 power supplies as the rear end load, the effect of net electricity to electric used in the running of control oil pumper 7 automatically when the windmill brake is stopped using.When wind speed was excessive, the wind-driven generator power output surpassed the use power of whole loads, and system start-up off-load resistance box 4 is laid down unnecessary electric weight by PWM mode (Pulse Width Modulation, pulse width modulation) by off-load resistance box 4.If wind-force continues to increase, the wind power of wind-driven generator 1 surpasses rated power, when surpassing safe speed of rotation, and the system start-up brake structure, wind-driven generator 1 stall is controlled oily machine load and is all adopted the net electric operation.
Preferable, the rated power of described wind-driven generator 1 is 30KW, when generated output surpasses 30KW, opens brake; The off-load electrical voltage point of boost pressure controller 3 is AC440V, and the off-load resistance box is 8 tunnel control HY-WBL-80K off-load casees; The complementary control cubicle 5 of wind-powered electricity generation net electricity is the complementary control cubicle of HY-WGHC-W20G30 wind net, quantity is one or more, so that simultaneously to complementary control cubicle 5 power supplies of one or more wind-powered electricity generation net electricity, power 30KW, the power of its wind-powered electricity generation that inserts in parallel, net electricity is set at 20KW, 30KW respectively.
The above is preferred embodiment of the present utility model only, is not that the utility model is done any pro forma qualification.Any change that is equal to, modification or differentiation etc. that all those skilled in the art utilize the technical solution of the utility model that the foregoing description is made all still belong in the scope of the technical solution of the utility model.
