Embodiment
As Fig. 1, the present invention is a kind of compact conformation, the wind-driven generator parallel network reverse integral controller simultaneously possessing braking and invert function, and comprise main control unit 1, main control unit 1 control connection has deceleration of electrons module 2 and inverter module 3.Described deceleration of electrons module 2 is for doing the operation of short circuit or releasing short circuit to blower fan generator; And power to described inverter module 3 for closing or recovering generator; Described inverter module 3 flows to external electrical network for the electric power exported by generator; Described main control unit 1 is for controlling disconnection or the connection of deceleration of electrons module 2.
As a specific embodiment, physical circuit of the present invention is as Fig. 2, main control unit 1 is containing monitoring modulars such as generator voltage, line voltage, phase place, frequency, grid cut-off, grid-connected voltage, electric current, power, and what be connected with main control unit 1 has generator maximal power tracing module 4, inverter module 3, anti-islanding units 5, generator state monitoring module 6 and communication module 7; Communication module 7 adopts RS485 communication module, and outer computer can carry out communication by RS485 communication module and controller of the present invention, and same communication module 7 can also adopt other communications protocol such as RS232.
This controller also has AC/DC transducer 8 and Anti-surging device 9, AC/DC transducer 8 connects generator maximal power tracing module 4 and generator state monitoring module 6 respectively.Anti-surging device 9 is arranged between the output of wind-driven generator 12 and AC/DC transducer 8, shields.
At the output loop of wind-driven generator 12, also be connected with deceleration of electrons module 2 and manual braking device 11, deceleration of electrons module 2 is also connected on main control unit 1 and is controlled by it, for accepting the order of main control unit 1, implementing short circuit or remove the operation of short circuit to wind-driven generator.Manual braking device 11, adopts hand switch, for manual operation to the short circuit of wind-driven generator 12 or releasing short circuit.
In the course of work, when wind-driven generator 12 generates electricity, manual braking device 11 is in releasing short-circuit condition, and the relay switch that main control unit 1 controls deceleration of electrons module 2 inside disconnects; Direct current is converted to alternating current through AC/DC conversion, inverter module 3 by electric energy successively, and under the control of main control unit 1, direct current changes out the alternating current meeting grid requirements through inversion, eventually passes the output of anti-islanding units 5 and enters electrical network 10.
