Referring to FIG. 1, Fig. 1 is a kind of implementation flow chart of busbar voltage control method in the present invention, this method is applied to
In ups system, comprising the following steps:
Step S101: load current and busbar voltage are obtained.
Load current and busbar voltage can be obtained by controller, specifically, can be by correlation detecting circuit or sensing
Device carries out the detection of load current and busbar voltage, and will test result and be sent to controller.Such as it can directly pass through electricity
Current transformer detects load current, for another example can first detect associated voltage amount and then calculate load current.
Step S102: when the load current got reaches preset no-load current, by preset unloaded busbar voltage
Value controls busbar voltage as aim parameter, so that busbar voltage reaches unloaded bus voltage value.
After obtaining load current and busbar voltage, controller can be determined according to the size of load current
Corresponding aim parameter realizes the control to busbar voltage.
Controller can be based on closed loop feedback control, so that busbar voltage reaches mesh when carrying out the control of busbar voltage
Scalar, certainly, the value of the aim parameter are determined by controller according to the size of load current, that is to say, that the aim parameter
It is the variable quantity influenced by the size of load current.
Specifically, controller will be by preset zero load when the load current got reaches preset no-load current
Bus voltage value is as aim parameter, to control busbar voltage.
It should be pointed out that load current is to have reached zero load naturally when load current is equal to preset no-load current
Electric current.But in practical applications, it is contemplated that the factors such as detection accuracy also will be considered that negative when load current is close to no-load current
It carries electric current and has reached no-load current.That is, a range can be set, when the size of load current meets this range, just it is considered as
Preset no-load current is reached, certainly, the value of the range can be set according to the actual situation.For in step S103
It is such that the load current of description, which reaches preset full-load current also,.Such as in a kind of specific occasion, preset full-load current
For 100A, it is contemplated that detection accuracy, when detecting load current is 99.8A, controller can determine that load current reaches
Preset full-load current.
The value of unloaded bus voltage value can also be set previously according to actual needs, but it should be recognized that should
Value is it is required that occur zero load to when fully loaded mutation, the minimum of busbar voltage also wants > 311V, that is, extreme feelings are occurring
When the dynamic electric voltage transition of condition, busbar voltage still has enough energy support output voltage stabilizations in 220V.
In a specific embodiment, according to experimental data and theory analysis, unloaded bus voltage value is preset as
380V, such setting enable to that zero load is occurring to when fully loaded mutation, and the minimum of busbar voltage is also above 311V.
Step S103: when the load current got reaches preset full-load current, by preset fully loaded busbar voltage
Value controls busbar voltage as aim parameter, so that busbar voltage reaches fully loaded bus voltage value；Wherein, unloaded bus electricity
Pressure value is greater than fully loaded bus voltage value.
It, can be by preset fully loaded bus voltage value when the load current that controller is got reaches preset full-load current
As aim parameter, busbar voltage is controlled.Preset fully loaded bus voltage value has lower than preset unloaded bus voltage value
Conducive to raising full load efficiency.In a specific embodiment, according to experimental data and theory analysis, preset fully loaded bus
Voltage value is 360V, is enabled in full load, and ups system can have higher full load efficiency, while the busbar voltage of 360V,
Even if can also have enough energy support output voltage stabilizations in 311V when line loss is larger.
Using technical solution provided by the embodiment of the present invention, be applied in ups system, comprising: obtain load current with
And busbar voltage；When the load current got reaches preset no-load current, using preset unloaded bus voltage value as
Aim parameter controls busbar voltage, so that busbar voltage reaches unloaded bus voltage value；When the load current got reaches
When to preset full-load current, busbar voltage is controlled using preset fully loaded bus voltage value as aim parameter, so that female
Line voltage reaches fully loaded bus voltage value；Wherein, unloaded bus voltage value is greater than fully loaded bus voltage value.
In the scheme of the application, control bus voltage reaches aim parameter, this aim parameter is not a fixed value, but
It is determined by load current.Specifically, that is, load current reaches preset no-load current when ups system is under light condition
When, the application can give a higher aim parameter, i.e. control bus voltage reaches unloaded bus voltage value.And work as ups system
Under full load condition, i.e., when load current reaches preset full-load current, the application understand control bus voltage be in one compared with
Low value, i.e., fully loaded bus voltage value.Since in a fully loaded state, busbar voltage is lower fully loaded bus voltage value, also
The case where being not in reduction full load efficiency in the prior art.And when uprushing if there is zero load to fully loaded situation, this Shen
Although please scheme can control bus voltage from higher unloaded bus voltage value switch to lower fully loaded bus voltage value, cut
Change the certain delay of process naturally occurring, this is also meaned that, occur dynamic electric voltage transition this during, busbar voltage is also
It is held in higher unloaded bus voltage value.Since busbar voltage is maintained at a higher numerical value, even if dynamic has occurred
Voltage transient, the stabilization that bus also still has enough energy to support output voltage.Therefore, the scheme of the application is in reply dynamic electric
When pressing transition, full load efficiency has been taken into account.
In a kind of specific embodiment of the invention, further includes:
It is corresponding according to preset voltage and current when the load current got is greater than no-load current and is less than full-load current
Relationship controls busbar voltage as aim parameter for bus voltage value corresponding to current load current, so that female
Line voltage reaches currently determining aim parameter.
In the aforementioned embodiment, dynamic electric voltage transition has been carried out to this situation the most extreme is fully loaded with for zero load
Protection, has combined full load efficiency.In this kind of embodiment, it is contemplated that ups system can also work the undercapacity the case where, when
When load is uprushed, a degree of dynamic electric voltage transition can also occur, such as semi-load uprush to fully loaded.Therefore, this kind of embodiment party
In formula, when the load current got is greater than no-load current and is less than full-load current, controller also can be according to preset voltage
Electric current corresponding relationship determines the aim parameter corresponding to present load current, and then controls busbar voltage.
Certainly, the setting of voltage and current corresponding relationship, it is desirable to be able to cope with dynamic electric voltage transition and take into account efficiency.Such as
In a specific embodiment, the bus voltage value in voltage and current corresponding relationship and be linear corresponding pass between load current
System, and bus voltage value and load current are negatively correlated.
It is still 380V with hollow load bus voltage value above convenient for description, fully loaded bus voltage value is said for being 360V
It is bright.That is, for controller using 380V as aim parameter, control bus voltage is 380V, in full load, controller control in zero load
Busbar voltage is 360V.And when zero load is between fully loaded, controller according to preset voltage and current corresponding relationship, will with it is current
Load current corresponding to bus voltage value busbar voltage is controlled as aim parameter.In this kind of embodiment, voltage
It is linear corresponding relation between bus voltage value and load current in electric current corresponding relationship, and bus voltage value and load current
It is negatively correlated.That is, the bus voltage value corresponding to load current is lower, i.e. controller with the raising of load current
The aim parameter determined is lower.
And it is pointed out that each voltage value in the voltage and current corresponding relationship is usually below preset zero load
Bus voltage value is above preset fully loaded bus voltage value.Such as unloaded bus voltage value is 380V, is fully loaded with bus voltage value
For 360V, in zero load between fully loaded, bus voltage value in voltage and current corresponding relationship is from 380V to 360V and load current
It is linear corresponding.
In a kind of specific embodiment of the invention, the corresponding relationship between bus voltage value and load current is to pass through
The corresponding relationship that following two step determines:
First step: being N number of subinterval by this interval division of no-load current to full-load current, and each subinterval is equal
For continuum, N is positive integer and N >=2；
Second step: being directed to each subinterval, configures corresponding voltage value for the subinterval, wherein the subinterval
When lower current limit is lower, the voltage value of configuration is higher.
In view of in aforementioned embodiments, voltage and current corresponding relationship is linear corresponding relation, although being conducive to carry out female
Line voltage accurately controls, but load current variation it is smaller when, it is also possible to need constantly to carry out the adjusting of busbar voltage.Therefore
It is N number of subinterval by this interval division of no-load current to full-load current in this kind of embodiment, so that changing in load current
When smaller, it may not be necessary to which the adjusting for excessively carrying out busbar voltage advantageously reduces adjustment cost.
For example, no-load current to this section of full-load current is 0A to 100A, every 20A is divided into a subinterval.For
This 5 subintervals, when being greater than 0 less than or equal to 20A, the voltage value of configuration is 376V, when being greater than 20 less than or equal to 40A, configuration
Voltage value is 372V etc..Certainly, it should be noted that when dividing subinterval, can be evenly dividing, it can also be non-homogeneous stroke
Point.The difference of the voltage value of adjacent interval configuration, can be the same or different, not influence implementation of the invention.
In a kind of specific embodiment of the invention, further includes:
When the load current got exceeds full-load current, and duration exceeds preset first duration, exported
Carry prompt information.
Since load current exceeds full-load current, and duration is longer, that is, has exceeded preset first duration, this kind of reality
Applying the controller in mode, just output overloading prompt information advantageously reduces so that related personnel notices the situation in time
Failure risk.Certainly, in portioned product, power supply can also be automatically cut off to further decrease after overloading certain time length
Overload risk.
