Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is elaborated.
Internal combustion engine in oil-electric engine group can be Diesel engine, it is also possible to be petrol engine, no matter what is
Planting engine, being required for heat radiation in its course of work, therefore oil-electric engine group is provided with cooling system, needs the parts of heat radiation
Possible more than one, therefore cooling system includes the coolant that at least one tunnel circulates, the cylinder sleeve of such as engine needs heat radiation,
Then arranging a road coolant to dispel the heat to cylinder sleeve, remaining needs the parts of heat radiation similar, and coolant circulates to be taken away and need to dispel the heat
The heat of parts, thus give the heat radiation of this parts, but now the temperature of coolant will rise, and therefore also needs the heat of coolant
Quick diffusing, in air, includes at least one heat sink for this cooling system, its respectively with each road coolant one_to_one corresponding,
Each heat sink includes several radiator fans, for a corresponding road coolant cooling.Coolant be typically than
The bigger liquid of heat capacity ratio, water is the most frequently used coolant, when water is used as coolant, is referred to as cooling water.
It is respectively provided with temperature sensor in the pipeline of each road coolant, such as PT100 thermocouple sensor, it is used for detecting
The temperature of coolant, naturally it is also possible to use other technologies means to detect the temperature of coolant, this is prior art, at this not
Launch explanation.The oil-electric engine group control method of the present embodiment is mainly, after oil-electric engine group starts, and each cooling
The radiator fan of device does not first start, and monitors the temperature of each road coolant respectively, if the temperature of certain road coolant is in default temperature
When more than degree threshold value, now just start the radiator fan with this corresponding heat sink of road coolant, allow radiator fan to this road
Coolant is lowered the temperature.Each heat sink only runs with the temperature of a corresponding road coolant for condition, and each road cools down
The preset temperature threshold value of liquid is also not quite similar, and for example, gives a road coolant (calling jacket water in the following text) of the cylinder sleeve heat radiation of engine, cylinder
The temperature threshold that set water is preset is 45 DEG C, then when the temperature only at jacket water rises to 45 DEG C, and the corresponding cooling with jacket water
Radiator fan in device just can be by control startup optimization, and no matter the temperature of other road coolants is preset either with or without reaching corresponding
Whether temperature threshold, impact all without to the startup of the radiator fan in heat sink corresponding with jacket water.Give respectively
Each road coolant arranges temperature threshold, and whether triggers phase as condition more than preset temperature threshold value using the temperature of coolant
Radiator fan startup optimization in the heat sink answered, the purpose of this measure is to allow radiator fan together not start with generating set, from
And avoid generating set startup stage load excessive and cause internal combustion engine easily stop working and starting current excessive to generator
Group causes bigger impact, during because the temperature threshold of coolant determines the startup of radiator fan in corresponding heat sink
Machine, so the temperature threshold presetting to each road coolant is most important, if temperature threshold is too low, will allow radiator fan too early
Starting, generating set startup stage thus giving increases excessive load；If temperature threshold is too high, radiation air will be allowed
Fan starts too late, it is impossible in time to coolant cooling, make certain parts of generating set the situation that heat gathers occur.Therefore,
The temperature threshold preset to each road coolant should be suitable, and the radiator fan in corresponding heat sink both will not have been allowed to start too early
Increase excessive load to generating set, the radiator fan startup optimization too late in corresponding heat sink also will not be allowed to cause sending out
The corresponding component of group of motors occurs that heat gathers, the too high situation of temperature.It should be noted that due to the temperature of each road coolant
Being not quite similar, respective temperature threshold is also different, and the radiator fan in each heat sink also will not start simultaneously, at generator
Group arrives the period between normal work after starting, it is also possible to allow a small amount of radiator fan startup optimization, as long as generating will not be given
The too big load of unit increase.
In a further embodiment, it is also possible to generating set is normally worked as start radiator fan condition it
The temperature of one, Ji Mou road coolant is more than corresponding preset temperature threshold value and generating set normally works the two condition together
Shi Dacheng, just starts the radiator fan in corresponding heat sink.Herein, generating set normally works and refers to its output voltage
Reach normal level, can have been judged by detecting its output voltage whether generating set completes to start to start normal work.
Further, when the temperature of certain road coolant rises to corresponding preset temperature threshold value, the cooling of this road is also not conveyed
Whole radiator fans in the corresponding heat sink of liquid all together startup optimization, but first startup optimization part radiator fan, so
The temperature of Hou Zaishigai road coolant rises situation and takes the circumstances into consideration to increase startup radiator fan, say, that according to this road coolant
Temperature variations adjusts the quantity with the radiator fan of operation in this corresponding heat sink of road coolant, makes this cooling fill
The quantity of the radiator fan putting middle operation raises with the temperature of this road coolant and increases, and reduces with described temperature and reduces.Institute
There is radiator fan all to run always, adjust the operation quantity of radiator fan, environmental protection and energy saving according to radiating requirements.Additionally,
Under this further technical scheme, said temperature threshold value can be set depending on concrete condition, if the output of generating set
Power is bigger, starts a small amount of radiator fan and is also not result in loading excessive, then also can lead to startup stage generating set
Cross arrange relatively low temperature threshold to allow a small amount of radiator fan generating set startup stage with regard to startup optimization, if energy
Reach mitigate generating set startup stage load so that internal combustion engine is not easy the purpose stopped working in this stage, visually have
Body situation arranges said temperature threshold value flexibly.
Specifically, the quantity allowing the radiator fan running in each heat sink becomes with the temperature of corresponding coolant respectively
Change and the scheme that changes it may be that preset multiple continuous print temperature range to every road coolant, corresponding one of each temperature range
With the quantity of radiator fan run in this corresponding heat sink of road coolant, control in this heat sink current run dissipate
The quantity of Hot-air fan is the quantity corresponding to the temperature range residing for the Current Temperatures of this road coolant.With jacket water and and cylinder sleeve
As a example by the corresponding heat sink of water, the preset temperature threshold value of jacket water is 45 DEG C, and the first temperature range is 45 DEG C-55 DEG C, second
Temperature range is 55 DEG C-70 DEG C, and the 3rd temperature range is 70 DEG C-85 DEG C, and the 4th temperature range is more than 85 DEG C, the temperature of jacket water
When degree rises to 45 DEG C, one of this heat sink radiator fan startup optimization；The temperature of jacket water continues to rise, and reaches 55 DEG C
When, the quantity of the radiator fan running in this heat sink increases to 2；The temperature of jacket water continues to rise, when reaching 70 DEG C,
The quantity of the radiator fan running in this heat sink increases to 3；The temperature of jacket water continues to rise, when reaching 85 DEG C, and should
Whole radiator fans all startup optimization in heat sink；If now the temperature of jacket water declines, when being brought down below 85 DEG C, should
The quantity of the radiator fan running in heat sink is reduced to 3；The temperature of jacket water continues to decline, when being brought down below 70 DEG C,
The quantity of the radiator fan running in this heat sink is reduced to 2；If now the temperature of jacket water rises again, rise to 70
DEG C when, the quantity of radiator fan run in this heat sink increases to again 3.Other coolants and corresponding heat sink
The course of work is in like manner.It is of course also possible to be set lower than the temperature range of preset temperature threshold value, but the temperature of coolant is in this temperature
During degree scope, the quantity of the radiator fan running in corresponding heat sink is 0.
In addition, the oil-electric engine group control method of the present embodiment is always according to can be properly functioning in each heat sink
The quantity of radiator fan draws the peak power output of generating set, limits the power output of generating set with this defeated in this maximum
Go out below power.Have radiator fan break down cannot properly functioning in the case of, internal combustion engine can be prevented because of the excessive work(of output
Rate causes generating heat in a large number and can not dispelling the heat in time, and now generator unit can also continue to power to the load, simply maximum work output
Rate is restricted, and after waiting until to complete power supply task, then shuts down and keeps in repair the radiator fan breaking down, from without
The work of generating set is interrupted in midway.
Method given herein, all or part of step therein can be by setting up functional module construction, by computer
Programmed instruction control computer system completes.These computer program instructions store in a computer-readable storage medium.
The above disclosed preferred embodiment being only the invention, can not limit present invention wound with this certainly
The interest field made, the equivalent variations therefore made according to the invention claim, still belong to the invention and covered
