The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.In addition,, in each embodiment of described the utility model, involved technical characterictic just can combine mutually as long as do not form each other conflict.
Fig. 1 shows the modular construction of the propulsion of ship load simulating device that the utility model provides, and for convenience of explanation, only shows the part relevant to the utility model, and details are as follows:
In the utility model, propulsion of ship load simulating device comprises controller 10, torque sensor 11, motor 12, inverter 13, the first collector 14, the second collector 15, the first gate-controlled switch K1 and the second gate-controlled switch K2; Motor 12 is connected with outside propelling unit 2, by propelling unit 2 drive motor 12, works; The input end of torque sensor 11 is connected to the coupling end that described motor 12 is connected with propelling unit 2; The first input end of controller 10 is for being connected with described propelling unit 2, and the second input end of controller 10 is connected to the mouth of described torque sensor 11; The 3rd input end of controller 10 is connected to the mouth of described the first collector 14, and the four-input terminal of controller 10 is connected to the mouth of the second collector 15; The first gate-controlled switch K1, inverter 13 and the second gate-controlled switch K2 are connected between motor 12 and outside utility grid 3 successively; The control end of the first gate-controlled switch K1 is connected to the first mouth of controller 10, and the control end of the second gate-controlled switch K2 is connected to the second mouth of controller 10; The input end of the first collector 14 is connected to the coupling end that inverter 13 is connected with the second gate-controlled switch K2, and the input end of the second collector 15 is connected to the coupling end that the second gate-controlled switch K2 is connected with utility grid 3.
Advance simulation while carrying out, by controller 10, export a setting speed signal to propelling unit 2, make it by setting speed operation drive motor 12 generating output direct supplys, then controller 10 is controlled the first gate-controlled switch K1 closure and is powered to inverter 13; After inverter 13 work, controller gathers inverter by the first collector 14 and the second collector 15 and exchanges outgoing side and utility grid electric quantity signal, through data analysis, controls gate-controlled switch K2 combined floodgate after inverter and AC network reach condition for parallel connection.After grid-connected success, inverter 13 and motor 12 will be born a part of network load, this Time Controller 10 gathers cardan shaft torque signals by torque sensor 11, and under this rotating speed, answer the moment of specified output to compare this signal and propelling unit 2, form closed loop control, if actual value moment control inverter 13 frequencies less than normal rise, increase load, if actual moment control inverter 13 frequencies bigger than normal decline, reduce load.Propelling unit actual output torque is consistent with rated moment adjustment the most at last, realizes and advances load simulation function.
In the utility model, because dynamo generator has, response is fast, overload torque is large, be easy to control and the high feature of reliability, so adopt dynamo generator as load motor 12 in the utility model.Wherein, dynamo generator can have multiple, and the DC generation unit of formation can be connected by cable with inverter.
In the utility model, controller 10 is for controlling the increase of propelling unit rotating speed and reducing, be responsible for receiving the collection output signal of torque sensor 11, the first collector 14 and the second collector 15 simultaneously, after data processing, realize combined floodgate, separating brake and the torque-feedback of gate-controlled switch.Torque sensor 11 is for gathering torque signals on cardan shaft, and can adopt model is the chip realization of JN338-A.Motor 12 can adopt QDTY-21-4 type DC generation unit.Inverter 13 can adopt NHI-NB-I type inverter.The first collector 14 exchanges outgoing side electric quantity signal for gathering inverter, and can adopt model is the electric quantity collector realization of NHI-CJ-AC.The second collector 15 is for gathering utility grid electric quantity signal, and can adopt model is the electric quantity collector realization of NHI-CJ-AC.The first gate-controlled switch K1 and the second gate-controlled switch K2 all can adopt circuit breaker to realize.
In the utility model, when the resisting moment on DC generation arbor is worked with propelling unit, resisting moment is consistent.Now only needing to adjust DC generation unit outgoing current is to export torque on capable of regulating dynamo generator group axle, thereby adjusts propelling unit output torque and horsepower output.Consider that the operation of actual marine propuision system is can inverted running, require the DC generation unit armature current can be reverse.On cardan shaft, be provided with torque sensor, measured torque feed back to that propelling unit and input speed given value convert and torque value compare, to form closed loop moment controlling system.During system works, propelling unit band dynamotor rotary electrification.The output circuit breaker (i.e. the first gate-controlled switch K1) of this Time Controller control dynamo generator closes a floodgate, and inverter is started working.Controller is by gathering and comparing inverter AC and utility grid voltage, frequency and phase signal, control inverter and utility grid parallel operation.When after the input of propelling unit tach signal, by transformation calculations, draw the corresponding torque value of this rotating speed, system compares it and torque value of feedback, if actual feedback is less than input value, the controller inverter AC output frequency that raises, grid-connected inverters bears utility grid load and becomes large, increases dynamo generator outgoing current, thereby increases output torque; If otherwise actual feedback is greater than input value, controller reduces inverter AC output frequency, and grid-connected inverters bears utility grid load and diminishes, and reduces dynamo generator outgoing current, thereby reduces output torque.
The propulsion of ship load simulating device that the utility model provides can be installed on various places flexibly, can reappear propeller characteristic.For marine propeller provides axle load true to nature, not only considered the characteristic of propulsion system itself, also considered the impact of propelling unit rotating speed on propulsion system.
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 domain of the present utility model.
