Description
Technical field
The utility model relates to a kind of long distance control system, particularly a kind of synchronous excitation motor long distance control system.
Background technology
Because high voltage synchronous machine has advantage at operational reliability and aspects such as plant maintenance, power factor, controllability, weak magnetic compare, and for large-size machine, has trended towards adopting synchronous motor.Synchronous motor is a kind of alternating current generator commonly used, and characteristics are: during steady-state operation, relation of constant n=ns=60f/p is arranged between the rotating speed of rotor and the mains frequency, ns is called synchronous rotational speed.If the frequency of electrical network is constant, then the rotating speed perseverance of synchronous motor is irrelevant with the size of load for constant during stable state.All adopt synchronous motor as power like the powerful device in the industries such as high power gas transmission & distribution station force feed machine, air compressor, conveying water pump on the commercial Application, use one of power-equipment more widely so synchronous motor is each industrial trade.
At present, the operation of state's inner synchronous machine adopts switchboard electric brake direct control basically, if will it be applied in inflammable and explosive occasion, just must adopt explosion-proof technology.But existing synchronous motor does not have monitoring function, is prone to cause danger, and can not satisfy people's requirement.
Summary of the invention
It is a kind of easy to use, safe that the purpose of the utility model just is to provide, and has the synchronous excitation motor long distance control system of monitoring function.
To achieve these goals; The technical scheme that the utility model adopts is such: the synchronous excitation motor long distance control system of the utility model; Comprise synchronous motor, control module, power excitation module and automatic exciting regulator, the output terminal of controller connects the output terminal of power excitation module, and the output terminal of power excitation module connects the input end of automatic exciting regulator; The output terminal of automatic exciting regulator connects synchronous motor; The output terminal of said synchronous motor connects the input end of a switchboard, the input end of the output terminal link control module of switchboard, and the output terminal of control module also connects a monitor supervision platform.
As preferably, said monitor supervision platform is connected through the DH485 network with control module.
As preferably, said control module is connected through the RS485 interface with switchboard.
As preferably, said control module is the PLC controller.
Compared with prior art, the advantage of the utility model is: this supervisory system combines the function that the power excitation is regulated and monitored automatically, makes the operator not only can carry out remote monitoring to high voltage synchronous machine at Control Room; And can monitor in real time the operation of synchronous motor; Operation conditions trend is provided, and functions such as service data inquiry possess the management function to synchronous motor simultaneously; Make synchronous motor not have slip, adjusting speed accuracy is high.Control module is the PLC controller; Adopt the PLC logic control mode to guarantee that the excitation of synchronous motor starts; Avoided exempting from causing the phenomenon of electric motor starting failure because of rotor-position is out of one's reckoning; Overcome the shortcoming that the output power of synchronous motor can not be regulated voluntarily, improved the synchronous motor reliability of operation.
