The utility model, for the axle generator of adjustable propeller (CPP) pattern and the ocean engineering vehicle automatic power plant of diesel engine generator hybrid power plant, provides more stable control system flexibly.This system is that every generating set configures a set of power controller (PCU), is every a set of electron speed regulator of adjustable propeller host configuration (ESC).Every cover power controller is responsible for the information about power of sampling, and connects by signal interconnection, to realize the intercommunication adjustment to every power of the assembling unit allocation manager.Require the electron speed regulator of adjustable propeller main frame can realize the adjustment on a large scale of engine speed and power output and stable, can realize again the fine setting of Remote speed-regulating signal to engine speed.
The control system the utility model proposes, the axle generator of realizing multiple pattern that can be flexible, easy and diesel engine generator turner condition, and more reliable and more stable, in design, production, debugging and use, there is larger change.
The utility model most importantly require the upper and lower limited range of the speed governing of adjustable propeller main frame should reach its rated speed ± 2%, electron speed regulator can be realized the adjustment on a large scale of engine speed and power output and stable, can realize again Remote the speed-regulating signal fine setting to engine speed, especially the latter.
Because of adjustable propeller main frame be generally constant under rated speed continuous service, after gear box no-load voltage ratio, axle generator output frequency is basicly stable in about 50Hz.If realize the also car frequency adjustment to axle generator, it is adjustable within the scope of 50Hz ± 1Hz that the fine setting scope of engine speed should at least meet axle generator output frequency.

Under adjustable mode, PCU corresponding to axle generator is according to the electrical network collecting and treat and generator frequency is analyzed, and can send rotating speed fine adjustment signal to main frame, makes to treat and the frequency of generator meets and car requirement.In the process that also car is adjusted, PCU also should adjust engine speed in real time by the generator output frequency collecting, output frequency is stabilized within the scope of 50Hz ± 0.3Hz, this has also guaranteed that main frame rotating speed under adjustable mode is basicly stable in 1% scope of rated speed, thereby advances power output not cause too large impact on boats and ships active force.
It is more than the control principle of this control system, because control system is at axle generator in short-term and under car or transfer load operating mode, can only to main frame own, carry out rotating speed fine setting, other are not affected substantially at net unit, process time is shorter, control operation is easy, even can complete between axle generator and axle generator in short-term and car and transfer load, the flexibility while greatly also having strengthened Ship Power Station change working.
The control system that the utility model provides contrasts the control system that existing adjustable propeller engine speed can not be finely tuned, and its operating mode processing time is consuming time short, easy and simple to handle, and will get well the vernier control performance of main frame, and stability is high.This control system has not only realized axle generator and has processed with the operating mode in parallel in short-term between diesel engine generator, and the operating mode in short-term also having realized between axle generator and axle generator is processed, and this is more flexible when the change working of power station.During trial voyage, by correlation test, in six, seven grades of waves, in the situation that boats and ships half speed of a ship or plane travels, the also car of axle generator and diesel engine generator, the also car between axle generator and axle generator was no longer than one minute, and energy smooth transfer unit load.
Those skilled in the art will readily understand; the foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
