Fig. 1 is a structural representation of the present invention;
Fig. 2 is a main program flow chart;
Fig. 3 is the driftage flow chart.
Embodiment:
Below in conjunction with accompanying drawing, the invention will be further described by embodiment.
In an embodiment; a kind of little wind-powered electricity generation control gear; comprise SC system controller, wind energy controller, yaw system, strong wind protective system, Over Current Protection System; SC system controller is carried out the data command exchange by local interface and remote interface; controller of fan is gathered wind speed, wind direction, cabin direction, the voltage and current signal of blower fan and is sent into SC system controller; SC system controller is controlled each link of blower fan group at the data that collect; by the yaw system operation of going off course, protect by strong wind protective system, Over Current Protection System.
SC system controller is controlled the movement process of wind power generating set.After powering on, the running software of SC system controller can be divided into following several stages:
(1) initialization: SC system controller is each chip of initialization inside at first, guarantees the proper functioning of master chip.Then, unit is placed holding state, load main Operational Limits and system protection limit value simultaneously, move each measuring unit and sensor, the misdata when abandoning measuring unit and just having started working, after several seconds, each measuring unit promptly can be realized accurate measurement.
(2) self check: SC system controller places holding state with unit, moves each measuring unit and fault detection unit, if the fault of recording is then carried out error protection, and after pending fault is eliminated, the operation that can enter next stage.
(3) commencement of commercial operation: SC system controller is after self check finishes to confirm there is not fault; unit is placed automatic running state; the control command of the comprehensive determinant program of each measuring unit of circular flow, fault detection unit, protection action, exercises mechanism (comprise Yawing mechanism, braking mechanism, the mechanism of untying the mooring rope) is sent subroutine then, thereby realizes the control to unit.
1, fault treatment: Fault Diagnosis one is the size according to unit electric part measured value, the 2nd, and according to the switching signal that is installed in the sensor feedback of each critical piece of blower fan.Carry out integrated treatment having detected various faults.The standby fault is eliminated the back and is continued all do not have fault in the 30min, and the current fault state of scavenge system is automatic running state, otherwise keeps original state constant.
2, driftage function: the actuator of driftage function is a yaw motor, and the action command of yaw motor is sent by SC system controller.(1) wind speed stably is not less than certain value (as 3m/s), when wind speed is too low, though wind energy conversion system be in over against the direction of facining the wind, wind energy conversion system also can not generate electricity by way of merging two or more grid systems, this time, driftage was not only nonsensical, and can consume the electric power of electrical network because of the action of yaw motor.(2) be not in the process of untying the mooring rope, because the harm of winding fault is huge, so it is more important than driftage to untie the mooring rope; In addition, when untying the mooring rope, the cabin is to turn at least 10 minutes, thus be certain in this process the signal that wind direction does not align occur, and at this time system is in the machine halt trouble state and does not generate electricity by way of merging two or more grid systems at all, driftage need not yet.
3, the function of untying the mooring rope: the actuator of the action of untying the mooring rope also is a yaw motor, and the condition of the action of untying the mooring rope is: (1) had taken place to cross the winding fault, or the winding fault has taken place when wind speed is no more than certain value (as 10m/s).(2) twining fault is as judgment basis according to the cabin direction angle.As at wind speed less than 8m/s, the cabin direction angle is greater than 3000 ° or during less than 600 °.Because when being in winding, as twining down and to cause a serious accident again.So in case detected the winding fault, master controller is reported fault, ensuing yaw maneuver is under an embargo, thereby has prevented that cable from further twining.
4, strong wind protective function: the condition of strong wind protection action is: when wind speed surpasses definite value (as 10m/s), makes 90 ° of blower fan and wind deflections, prevents that the blade rotating speed is too fast, thus the protection generator.
5, motor overload protective function: the condition of motor overload protection action is: at alternating current (a.c.) during greater than motor full power electric current; make blower fan and wind deflection several angle; under the situation that satisfies the full power generating, prevent that the blade rotating speed is too fast, thus the protection generator.
