Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
In one embodiment, as shown in fig. 1, there is provided a data center power control method, which can be applied to a power control apparatus of a data center, including the steps of:
s102: and under the condition that a preset discharging time interval is reached, controlling the first UPS to start discharging until the residual electric quantity of the first UPS reaches a first discharging threshold corresponding to the current power utilization mode.
It should be appreciated that a UPS power source is a type of power conversion device. The utility power/generator is used as AC input energy source, and provides stable and reliable AC power supply for key load or sensitive load through proper conversion and regulation. The UPS power supply consists of an energy storage device and a conversion device, and when the commercial power is normal, the conversion device is used for stabilizing the commercial power and supplying power to the load, and simultaneously, the energy storage device is used for storing energy; when the mains supply fails, the energy storage device is used as an input energy source, and the power can still be continuously supplied to the key load until the mains supply is recovered or the generator is started to supply power or the energy storage is exhausted; and when the UPS equipment fails, the commercial power temporarily directly supplies power to the load through the bypass. The UPS is able to power the load without interruption in the event of a mains or a failure of the UPS's own equipment.
It should be understood that, in the embodiments of the present application, the data center power control method performs power control under the condition that the utility power is in normal operation, so the subsequent embodiments are all embodiments under the condition that the utility power is in normal operation unless otherwise specified.
It should be understood that the discharging time interval is a set time range in which the power supply can perform a control operation, where the control operation may include discharging, standby, charging, and the like, and the discharging time interval may be manually set time, or may be time in which devices such as a controller are automatically set according to a certain electricity usage rule, which is not particularly limited in this application.
In a preset discharging time interval, the first UPS power supply should perform discharging operation according to an electricity utilization mode corresponding to the current time during discharging, wherein the electricity utilization mode is a mode for controlling the power supply according to electricity utilization requirements and user requirements, and a control rule of the electricity utilization mode is to control the charging and discharging processes of the UPS power supply according to limiting conditions such as the residual capacity of the UPS power supply and a discharging threshold value, so that the UPS power supply is controlled to achieve an effect wanted by a user.
Optionally, as an embodiment, the monitoring device detects that the current time is within a discharge time interval, and controls the first UPS power source to discharge according to a current power supply mode of the UPS power source and a first discharge threshold corresponding to the power supply mode, until the residual electric quantity in the first UPS power source is reduced to the first discharge threshold.
Optionally, as an embodiment, the UPS power source is composed of a UPS, a control unit, a charging monitoring unit, and a discharging monitoring unit, where the control unit is used to control charging and discharging of the UPS battery and UPS switching, the charging monitoring unit is used to monitor a charging state of the battery, and the discharging monitoring unit is used to monitor a discharging state of the battery.
Alternatively, as an embodiment, the power source for charging and discharging includes not only a UPS power source, but also other mobile power sources, backup batteries, etc. that can be charged and discharged, which is not limited in detail in the embodiment of the present application.
S104: then, the second UPS power supply is controlled to start discharging until the residual electric quantity of the second UPS power supply reaches a second discharging threshold value corresponding to the current power utilization mode or the discharging time interval expires; the current power utilization mode comprises a peak power utilization mode or an off-peak power utilization mode, and the total discharge amount adjusted based on a first discharge threshold value and a second discharge threshold value corresponding to the peak power utilization mode is larger than the total discharge amount adjusted based on the first discharge threshold value and the second discharge threshold value corresponding to the off-peak power utilization mode.
It should be appreciated that the first UPS and the second UPS are two power sources, and the second UPS is controlled to discharge after the first UPS finishes discharging. The first UPS power supply and the second UPS power supply are sequentially discharged, potential safety hazards that the two UPS power supplies can cause electric energy waste and discharge simultaneously can be prevented, for example, when the two UPS power supplies discharge simultaneously, overload electric energy can be output to a load to cause electric energy waste, when the electric energy of the two UPS power supplies is consumed, if mains supply interruption occurs, the UPS power supplies do not have enough electric energy to provide standby electric energy.
The power consumption mode corresponding to the discharge of the second UPS power supply is controlled to be the same as the power consumption mode corresponding to the discharge of the first UPS power supply.
It should be understood that if the second UPS is controlled to discharge and the current time is within the discharge time interval, then the second UPS is controlled to discharge to the second discharge threshold; if the second UPS is controlled to discharge and the current time is outside the discharge time interval, that is, the discharge time interval expires, the discharging operation of the second UPS is stopped. If the current time runs from the discharge time interval to outside the discharge time interval, the control operation corresponding to the current power mode should be stopped, and the control operation may include charging, discharging, standby, and the like.
It should be understood that the current electricity mode may be a peak electricity mode or an off-peak electricity mode, and the method for judging the current electricity mode may be to determine whether the current electricity mode is the peak electricity mode according to electricity consumption conditions in a certain period of time, and if electricity consumption requirements in a certain period of time in the period of time are high or electricity prices are expensive, determine that the period of time is a peak period of electricity consumption, and the period of time matches the peak electricity mode; if the electricity demand is low or the electricity price is low in a certain time period in the time period, determining the time period as the off-peak electricity consumption period, wherein the time period is matched with the off-peak electricity consumption mode.
It should be understood that the UPS power source corresponding to the peak power consumption mode should provide more power for the load, so as to reduce the input power of the utility power, and finally alleviate the pressure of the utility power, or in a period of relatively expensive power price, the UPS power source should continuously output the internally stored power, thereby saving power and achieving the effect of reducing the power cost.
The UPS power source corresponding to the off-peak power consumption mode should reduce power supply, stop power supply, or charge, thereby reducing discharge of the UPS power source, or should continuously store power of the utility power during a period when the power price is low, so as to discharge when the power price is high.
Thus, the total amount of discharge adjusted by the first and second discharge thresholds corresponding to the peak power usage mode is greater than the total amount of discharge adjusted based on the first and second discharge thresholds corresponding to the off-peak power usage mode.
According to the data center power supply control method, the discharging is conducted in the preset discharging time interval, the specific discharging mode is determined according to the discharging time interval, the discharging is controlled in different modes, the discharging quantity is controlled through the discharging threshold value, the discharging quantity is guaranteed to be more in peak periods, less in off-peak periods, the electric energy resource is not wasted, the safety of the whole standby power supply system is guaranteed through the separated discharging of the first UPS power supply and the second UPS power supply, and therefore the data center power supply control method can achieve the effect of improving the electric energy resource utilization rate under the condition that the safety of the data center power supply is guaranteed.
In one embodiment, before the controlling the second UPS power source to begin discharging thereafter, the method further includes: and switching the first UPS power supply into a charging state until the residual electric quantity of the first UPS power supply reaches a first charging threshold corresponding to the current power utilization mode.
It should be appreciated that, in order to further ensure the power supply safety of the two UPS power sources, it is considered that after the first UPS power source is discharged, the first UPS power source enters a charging state and charges the remaining power of the first UPS power source to a first charging threshold corresponding to the current power consumption mode, where if the current power consumption mode is a peak power consumption mode, the first charging threshold is a charging threshold corresponding to the peak power consumption mode, and if the current power consumption mode is an off-peak power consumption mode, the first charging threshold is a charging threshold corresponding to the off-peak power consumption mode.
It should be appreciated that the first charge threshold should not be less than the first discharge threshold, and that the difference between the first charge threshold and the first discharge threshold may be used as the amount of power charged by the first UPS after the first UPS power source is discharged to the first discharge threshold.
It should be appreciated that the first charge threshold for the same first UPS power source in the peak power mode should be less than the first charge threshold in the off-peak power mode.
It should be appreciated that after the first UPS power source discharges, the second UPS power source can provide power at this time, and the second UPS power source can meet the power consumption requirement of the load, and after the first UPS power source charges to the first charging threshold, the second UPS power source discharges at this time, so that it can be ensured that in the whole time period, one power source of the first UPS power source or the second UPS power source can always cope with an emergency condition, and emergency power supply is provided.
Optionally, as an embodiment, after the first UPS power source discharges the remaining power to the first discharge threshold, the remaining power of the first UPS power source is charged to the first charge threshold according to the first charge threshold corresponding to the current power utilization mode.
In this embodiment, through the above steps, the first UPS power source can be controlled to perform charging operation after discharging through the first charging threshold, and the charged electric quantity is controlled, so that charging of the first UPS power source is controlled, and the second UPS power source stores the electric quantity, and the effect of improving the power supply safety of the two UPS power sources in the discharging process is achieved.
In one embodiment, after controlling the second UPS power source to begin discharging, further comprising: and under the condition that the residual electric quantity of the second UPS power supply reaches a second discharge threshold corresponding to the current power utilization mode and the discharge time interval does not expire, switching the second UPS power supply into a charging state until the residual electric quantity of the second UPS power supply reaches a second charge threshold corresponding to the current power utilization mode or the discharge time interval expires.
It should be appreciated that, in order to further ensure the power supply safety of the two UPS power sources, it is considered that after the second UPS power source discharges, the second UPS power source enters a charging state and charges the remaining power of the second UPS power source to a second charging threshold corresponding to the current power consumption mode, where if the current power consumption mode is the peak power consumption mode, the second charging threshold is a charging threshold corresponding to the peak power consumption mode, and if the current power consumption mode is the off-peak power consumption mode, the second charging threshold is a charging threshold corresponding to the off-peak power consumption mode.
It should be appreciated that the second charging threshold should not be less than the second discharging threshold, and that the difference between the second charging threshold and the second discharging threshold may be used as the amount of power charged by the second UPS after the second UPS has discharged to the second discharging threshold.
It should be appreciated that the second charge threshold for the same second UPS power source in the peak power mode should be less than the second charge threshold in the off-peak power mode.
It should be appreciated that after the second UPS power source discharges, the first UPS power source can provide power at this time, and the first UPS power source can meet the power consumption requirement of the load, and after the second UPS power source charges to the second charging threshold, both UPS power sources store power at this time, so that it can be ensured that at least one of the first UPS power source or the second UPS power source can cope with an emergency condition and provide emergency power.
It should be understood that the currently ongoing operation needs to be stopped when the discharge time interval expires, which may be a charging operation, a discharging operation. Therefore, if the present time has resulted in expiration of the discharge time interval in the above step, the discharge operation of the second UPS power source is stopped, or the charging operation of the second UPS power source is stopped.
In this embodiment, through the above steps, the second UPS power source can be controlled to perform charging operation after discharging through the second charging threshold, and the charged electric quantity is controlled, so that charging of the second UPS power source is controlled, and the first UPS power source stores the electric quantity, thereby achieving the effect of improving the power supply safety of the two UPS power sources in the discharging process.
In one embodiment, after the switching the second UPS power source to the charging state, the method further includes: and returning to execute the step of controlling the first UPS to start discharging when the residual electric quantity of the second UPS reaches a second charging threshold corresponding to the current power utilization mode and the discharging time interval does not expire.
It should be appreciated that if the discharging time interval does not expire, the step of starting discharging the first UPS may be repeated, and after the first UPS is discharged to the first discharging threshold, the first UPS is controlled to be charged to the first charging threshold, and then the second UPS is discharged to the second discharging threshold according to the second discharging threshold, and after the second UPS is discharged to the second discharging threshold, the second UPS is controlled to be charged to the second charging threshold. Finally, the effect of cyclic charge and discharge is achieved.
In this embodiment, through the above steps, the charging and discharging operations of the first UPS power source and the second UPS power source can be cyclically implemented, so as to achieve the effect of continuously improving the electric energy utilization rate.
In one embodiment, before the first UPS power source is controlled to start discharging when the preset discharging time interval is reached, the method further includes: acquiring the current time; if the current time is in a preset high electricity price time interval or a high electricity demand time interval, determining that the current electricity consumption mode is the peak electricity consumption mode; otherwise, determining the current power utilization mode as the off-peak power utilization mode.
It should be appreciated that the present time can determine whether it is within the discharge time interval at this time, thereby determining whether a power control operation is required. In addition to the high electricity price time interval and the high electricity demand time interval, the peak electricity consumption mode and the off-peak electricity consumption mode may be set according to other demands, which are not particularly limited herein.
In this embodiment, through the above steps, the peak electricity consumption mode and the off-peak electricity consumption mode can be flexibly set, so as to achieve the effect of improving the flexibility of electric energy resource conversion.
In one embodiment, if the current time is within a preset high electricity price time interval or a high electricity demand time interval, determining that the current electricity consumption mode is the peak electricity consumption mode; otherwise, after determining that the current power consumption mode is the off-peak power consumption mode, the method further comprises:

It should be understood that the amount of charge of the UPS power source should be small and the amount of discharge should be large in the peak power mode, so as to ensure that the UPS power source discharges more and charges less; the charging amount of the UPS power supply in the off-peak power consumption mode should be large, and the discharging amount should be small, so that the UPS power supply is ensured to be charged more and discharged less.
In this embodiment, through the above steps, the electric quantity control under different power utilization modes can be controlled through the charging threshold and the discharging threshold, so as to achieve the effects of further improving the safety of the UPS power source and improving the electric energy utilization rate.
