[embodiment]
Below in conjunction with embodiment and contrast accompanying drawing the present invention is explained further details.
Electronic equipment is a combining inverter in this embodiment.Control method is equally applicable to the electronic equipment that UPS, communication power supply etc. need the certain temperature range of work with device.Like Fig. 1, a kind of method of regulating the electronic equipment power output may further comprise the steps:
1) acquisition step: the actual value of the interior environment temperature when gathering combining inverter work.
2) comparison step: the peak of the interior environment temperature of actual value of gathering and combining inverter permission work is compared.
Wherein, the peak of the interior environment temperature of combining inverter permission work can obtain through heat test.If obstructed overheat test, general also directly the higher limit of the temperature of the radiator permission work of the power device of power taking subset as above-mentioned peak.The peak that obtains the interior environment temperature of combining inverter permission work through heat test in this embodiment is 70 degree.
3) regulating step: the power output of regulating combining inverter work according to comparative result.If actual value is higher than peak, then reduce the power output of combining inverter work at present; If actual value is lower than peak, the power output of the combining inverter work at present that then raises; If actual value equals peak, then keep the power output of combining inverter work at present.
The peak of the interior environment temperature of combining inverter permission work is 70 degree in this embodiment.During adjusting; Present output power like combining inverter is P1, and the actual value of the temperature of collection is higher than 70 degree, if current power adjustments amplitude is △ P1; Then regulate the back power output and be set at P1* (1-△ P1), return the adjustment process of entering power output next time then.In like manner; Power output like the combining inverter work at present is P2, and the actual value of the temperature of collection is lower than 70 degree, if the current amplitude of accommodation is △ P2; Then regulate the back power output and be set at P2* (1+ △ P2), return the adjustment process of entering power output next time then.Like this, after regulating several times, the actual value of the interior environment temperature of combining inverter will finally be stabilized near peak 70 degree, and power output remains unchanged, and adjustment process finishes.In the time of near the temperature actual value is stabilized in 70 degree, has just avoided combining inverter to work in and be higher than the situation that 70 degree might burn.And the temperature actual value finally be stabilized in 70 the degree after; The power output of combining inverter work at present also maintains the performance number of temperature stabilization correspondence when 70 spend; This value is the higher output power value of a corresponding maximum temperature value, has therefore also reached the big as far as possible purpose of power output when allowing electronic device works.
Regulate power output and can realize that the amplitude of accommodation that the power adjustments amplitude of setting is converted into the corresponding work electric current gets final product through this operating current of regulating electronic equipment.
Introduce several kinds of methods of setting the amplitude of accommodation of present output power as follows:
The control of A stepping.Set base and power adjustments step-length when regulating, before acquisition step, also comprise determining step: judge whether base arrives when regulating:, then get into acquisition step if arrive; If the arrival of base when regulating is then waited in no show.Base and power adjustments step-length are all set according to the variations in temperature of the electronic equipment of testing (being combining inverter in this embodiment) and the corresponding relation (temperature inertia) of power output variation during adjusting.If the temperature inertia of combining inverter is big, base and power adjustments step-length relative set are bigger when then regulating; If the temperature inertia of combining inverter is little, base and power adjustments step-length relative set are less when then regulating.As when regulating, set that base is 2 minutes when regulating, setting power is regulated the variation variable power 5% that step-length is per 5 degree of temperature; The temperature peak is 70 degree; If the current temperature actual value that records is 75 degree, then the power output amplitude of accommodation is for reducing by 5%, whenever at a distance from entering adjusting next time in 2 minutes; If the current temperature actual value that records is 80 degree, then the power output amplitude of accommodation is for reducing by 10%, whenever at a distance from entering adjusting next time in 2 minutes; If the current temperature actual value that records is 65 degree, then the power output amplitude of accommodation is for raising 10%, whenever at a distance from entering adjusting next time in 2 minutes.When regulating step-length according to the corresponding relation setting power of variations in temperature that tests out combining inverter and power output variation; As in the corresponding relation being every variation 6 degree of temperature; Power just changes 10%, and then setting power is regulated the variation variable power 10% that step-length is per 6 degree of temperature.The control method of stepping control control simplyr, but control mode is not so good as the rapidity and the sensitivity of following control method.
B sets according to ratio (P) control mode, and then the amplitude of accommodation of present output power is Kp* △ t, and wherein Kp is the first power adjustments ratio, and △ t is the difference between current actual value and the peak; The first power adjustments ratio Kp sets according to the corresponding relation of variations in temperature that tests out combining inverter and power output variation; Choose through experiment test; Both required electronic equipment finally can be operated under the safety condition, power output is a higher level when requiring electronic equipment finally to work again.During adjusting, as to set the first power adjustments ratio Kp be 2%, and the actual value of the temperature of current collection is C, and then the power adjustments amplitude is K=2%* ︱ C-70 ︱, according to the relevant value that raises or reduce present output power of the amplitude of accommodation.Because ratio control mode is the value of real-time regulated present output power, so the mode of its relative stepping control is quicker.
C sets according to integration (I) control mode; If currently be adjusted to the n time adjusting, n is the integer more than or equal to 1, and then the amplitude of accommodation of present output power is Ki* (Δ t1+ Δ t2+ ... + △ ti+ ... + △ tn); Wherein Ki is the second power adjustments ratio; Actual value when △ ti is the i time adjusting deducts the difference of peak, 1≤i≤n, and i is an integer.The second power adjustments ratio Ki sets according to the corresponding relation of variations in temperature that tests out combining inverter and power output variation; Choose through experiment test; Both required electronic equipment finally can be operated under the safety condition, power output is a higher level when requiring electronic equipment finally to work again.After choosing the second power adjustments ratio Ki, during adjusting, if currently be adjusted to the 1st adjusting, the actual value of sample temperature is 80, △ t1=80-70=10, and the then current amplitude of accommodation is Ki*10; When the 2nd time is regulated, currently be adjusted to the 2nd adjusting, the actual value of sample temperature is 75, △ t2=75-70=5, the then current amplitude of accommodation is Ki*10+Ki*5; When the 3rd time is regulated, currently be adjusted to the 3rd adjusting, the actual value of sample temperature is 65, △ t3=65-70=-5, the then current amplitude of accommodation is Ki*10+Ki*5+Ki* (5); And the like.Because the current amplitude of accommodation of integral control mode has comprised the aforementioned amplitude of accommodation repeatedly, so its control mode is except that having real-time, and its amplitude of accommodation is also more accurate.
D sets according to proportional integral (PI) control mode, establishes the current the n time adjusting that be adjusted to, and n is the integer more than or equal to 1; Then the amplitude of accommodation of present output power is Kp* △ tn+Ki* (△ t1+ △ t2+ ... + △ ti+ ... + △ tn); Wherein Kp is the first power adjustments ratio, and Ki is the second power adjustments ratio, and the actual value when △ ti is the i time adjusting deducts the difference of peak; 1≤i≤n, and i is an integer.The selection principle of the first power adjustments ratio Kp and the second power adjustments ratio Ki is the same: promptly set according to the corresponding relation of variations in temperature that tests out combining inverter and power output variation; Choose through experiment test; Both required electronic equipment finally can be operated under the safety condition, power output is a higher level when requiring electronic equipment finally to work again.The control mode of proportional integral is with the advantage of ratio control mode and integral control mode.
E is except the controlling schemes of the amplitude of accommodation of the setting present output power of above description, and other can realize the control mode of negative feedback control arbitrarily can also to adopt PID (PID) control, PREDICTIVE CONTROL, fuzzy control etc.
This embodiment also comprises a kind of device of regulating the electronic equipment power output.As shown in Figure 2, the device of regulating the electronic equipment power output comprises control module 100, acquisition module 200, comparison module 300 and adjustment module 400.The output of control module 100 connects the input of acquisition module 200; The output of acquisition module 200 connects the first input end of comparison module 300; The peak Tmax of the interior environment temperature of second input input electronic equipment permission work of comparison module 300; The output of comparison module 300 connects the input of adjustment module 400, and the feedback end of adjustment module 400 connects the feedback input end of acquisition module 200.
The startup acquired signal of acquisition module 200 reception control modules 100 inputs or adjustment module 400 are after the enabling signal once more of feedback end input; The actual value of the interior environment temperature when gathering electronic device works, and actual value is input to the first input end of comparison module 300.
The device of the adjusting electronic equipment power output in this embodiment, after regulating several times, the actual value of the interior environment temperature of electronic equipment will finally be stabilized near the peak, and power output remains unchanged.In the time of near the temperature actual value is stabilized in peak, just avoided electronic device works in being higher than the situation that peak might burn.And after the temperature actual value finally stablizes peak; The power output of electronic equipment work at present also maintains the performance number of temperature stabilization correspondence when peak; This value is the higher output power value of a corresponding temperature peak, has therefore also reached the big as far as possible purpose of power output when allowing electronic device works.
