Description
Technical field
The present invention relates to a kind of intelligent AC speed changing diesel generator group.
Background technology
Diesel generating set is lightweight, simple in structure with it, power density is widely used in greatly in all trades and professions, and in real world applications, all types of loads are divided into three major types, inductive load, resistive load, capacitive load
Wherein the most extensive with inductive load use, occupy the more than 70% of whole loads, such as motor, electricity-saving lamp, computer, communication class equipment.Although these inductive loads vary, divide and can be divided into two large class, the load of signal treatability and dynamic property loads according to function.Wherein dynamic property load has occupied the more than 80% of inductive load.Such as motor.Motor drives various loaded work pieces, according to Lenz's law---and faradic effect is always revolted and is caused faradic reason.The transient starting electric current of motor generally can reach 5-7 times of rated current, and single motor transient starting electric current is large again, but is negligible to the capacity of municipal electrical network.So the motor that connects municipal electrical network electricity consumption generally need not be considered the problem of starting current.But, if with the diesel generating set drive motor that generates electricity, the load of electric motor driven compressor of air conditioner or the large instant starting currents of this class of electric welding machine for particularly driving.The rated power of the diesel generating set of configuration will be than the large 3-5 of the rated power of load doubly.Because the capacity of diesel generating set is very limited to motor load.If the allocating power of unit is only larger than load rating power, instant starting currents is excessive so, and diesel engine cannot bear, then flame-out.The generator unit rated power of our general configuration than the large 3-5 of the rated power of motor load doubly in actual use.
In addition on the one hand, we most popular diesel generating set be that magnetic pole logarithm is the threephase alternator group of 4 grades, the frequency of three-phase diesel generating set output electric energy must remain on 50Hz, this just requires diesel engine speed must be stabilized in 1500RPM, according to horse-power formula P=9550*N*T, the power of diesel engine equals 9550 and is multiplied by rotating speed (N) and is multiplied by button square (T).The operable rotating speed of diesel engine for power generation is between 500-2200RPM, because the restriction of generating set frequency, the spendable rotating speed of diesel engine is between 900-1500, the maximum button square of diesel engine for power generation is at 1500RPM, the maximum button square of industrial diesel engine is at 1800RPM, same a Diesel engine (only has injection system difference, other is all the same), the diesel engine peak power output that engineering machinery is used is than diesel engine for power generation power large 15%-25%, in the time that low speed is unloaded, the diesel fuel consumption rate generator that engineering machinery is used is very low because of rotating speed by diesel engine fuel consumption low 10% in the time of zero load.
Because keep alternating current generator no matter be that zero load or the three-phase alternating current frequency of full load output all remain on 50Hz, so the power that Diesel engine is laid in like this can not be given full play of, in the time that generator is unloaded, because keep the rotating speed of 1500RPM, causing can not be with lower load running, thus many fuel consumption.
Although we configure the normal use that powerful diesel generating set can proof load, bring series of problems.After motor successfully starts, electric current revert to rapidly rated current, and this will cause the diesel generating set operation conditions in underloading for a long time, and this long-term low load with strong power can cause following problem:
(1) diesel generating set acquisition expenses is larger;
(2) the diesel generating set life-span shortens greatly;
(3) diesel generating set fuel consume increases, and causes operation cost huge.
Example:
There is motor-operated freezer compressor of a 7KW.50HZ.380V.3P.Rated current is about 12A, and transient starting current time is 60A.2S.
The diesel generating set rated power of load configuration must reach 21KW for this reason.Wherein diesel engine rated power must reach 22Kw (when 1500RPM) (maximum power is 24Kw (when 1500RPM)), can drive compressor normally to move.
If use transmission technology that remaining diesel engine 25% power is brought into play, can meet compressor and normally move for diesel engine rated power in the generating set of load configuration reaches 16.5Kw (when 1500RPM) (maximum power can reach 24Kw (when 2200RPM)) so.
In the situation that meeting equally bearing power demand, the diesel oil of the Diesel engine rated power 16.5Kw (when 1500RPM) of same brand (maximum power 24Kw (when 2200RPM)) will be cheaply than the Diesel engine price of rated power 22Kw (when 1500RPM) (maximum power 24KW (when 1500RPM)) nearly 25%.
When the rear oepration at full load of load starting success, the generating set dump power of 16.5KW (when 1500RPM) is 7KW.The engine dump power of 22KW is 2KW.16.5KW unit fuel consumption is 3.46L/h.The generating set fuel consumption of 22KW is 4.32L/h.Although the 0.68L fuel oil that expends per hour so more. do manual work identical.
Unit is due to long-term light running, burn deterioration.Can cause parts depreciation aggravation.Maintaining expense will increase greatly.
