Accompanying drawing explanation
Fig. 1 is schematic block circuit diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail.
As shown in Figure 1, the utility model provides oil-well rig diesel-generator set control system, and it comprises isochronous controller, excitation voltage regulation device, PLC processor, parameter acquisition module, speed controller and main disconnector.
Testing signal is sent to isochronous controller by described parameter acquisition module, comprises output voltage Detecting element, current measuring element and rotating speed Detecting element, and the information of collection is sent to storage stores.Processing signals is sent to PLC processor, speed controller and excitation voltage regulation device by isochronous controller.Control signal is sent to diesel generating set by excitation voltage regulation device and speed controller, and processing signals is passed to main disconnector and speed controller by PLC processor, and PLC processor is connected with indicator, and the working state of system is shown.
When unit operation, PLC processor is according to the start stop switch input state of control cabinet, and output command adapted thereto, to speed controller, allows diesel engine be operated in successively idling and rated velocity state.Set up when the voltage of generator, after voltage measurement element detects 600V voltage, now generator is reached the standard grade; Speed controller detects the rotating speed of controlling diesel engine, the voltage of excitation voltage regulation device control generator output, then under the control of isochronous controller module and PLC processor, send signal to throttle actuator and the field coil of diesel engine, make the state of diesel engine work at needs.In the whole process of generator operation, isochronous controller also receives the signal of voltage detector component, current measuring element and rotating speed Detecting element of monitoring generator set in real time, makes electric current, voltage, busbar voltage and diesel engine speed that it can Real-Time Monitoring generator.When occurring overvoltage/undervoltage, cross under-frequency, overcurrent etc., isochronous controller output trouble signal, to PLC processor, allows its output make main disconnector separating brake, reaches the object of protection diesel engine and generator.
When set grid-connection, the isochronous controller mould of unit to be reached the standard grade detects the gap of local frequency, voltage and reached the standard grade machine class frequency, voltage, and sends analog bias signals and to speed controller and the excitation voltage regulation device of this control cabinet, its output signal is adjusted in real time.After frequency, voltage are consistent respectively, send reclosing command to PLC processor, the parallel operation of PLC processor control breaker closing.After reaching the standard grade, several isochronous controllers pass through load distribution end port communications each other, and control signal is exported to speed controller and excitation voltage regulation device by twisted-pair feeder.Speed controller is controlled the rotating speed of diesel engine according to control signal, makes it to reach meritorious balanced requirement; Excitation voltage regulation device is adjusted the voltage of generator output according to control signal, makes it to reach the requirement of idle equilibrium.
Although by reference to the accompanying drawings embodiment of the present utility model is described in detail, should not be construed as the restriction of the protection domain to this patent.In the described scope of claims, the various modifications that those skilled in the art can make without creative work and distortion still belong to the protection domain of this patent.
