Detailed Description
Exemplary embodiments of the present disclosure are described below with reference to the accompanying drawings, in which various details of the embodiments of the disclosure are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
A power supply system 1 for a data center according to an embodiment of the present disclosure is described below with reference to fig. 1.
As shown in fig. 1, a power supply system 1 for a data center according to an embodiment of the present disclosure includes a high voltage dc power supply module 10 and a backup power supply module 20.
Specifically, the high-voltage dc power supply module 10 is configured to convert the input ac power into dc power with a first preset voltage and transmit the dc power to the dc bus 1 a. The standby power module 20 includes a plurality of standby power submodules 20a connected to the dc bus 1a and arranged in parallel, the standby power submodules 20a include a battery pack 21 and a converting unit 22, and the converting unit 22 switches between an input flow direction and an output flow direction to switch the battery pack 21 between a charging state and a discharging state. The conversion unit 22 is always in the output flow direction, and converts the output voltage of each battery pack 21 into the second preset voltage.
The high-voltage dc power supply module 10 has an ac input connected to the mains supply and a dc output connected to the dc bus 1 a. The high-voltage direct-current power supply module 10 converts alternating current into direct current with a first preset voltage, and then outputs the direct current to the direct-current bus 1 a. The direct current bus 1a is connected with the load equipment, so that direct current with first preset voltage supplies power to the load equipment through the direct current bus 1 a.
In one particular example, the high voltage DC power module 10 may include an alternating current transformer and an alternating current/direct current Converter (AC/DC Converter) arranged in series. The alternating current transformer is used for converting the input 220V alternating current into 380V alternating current and transmitting the 380V alternating current to the alternating current/direct current converter; the alternating current/direct current converter is used for converting 380V alternating current into direct current with first preset voltage and transmitting the direct current to the direct current bus 1 a. The first preset voltage may be 270V.
The standby power module 20 is used for supplying power to the load device through one or more standby power submodules 20a of the standby power module 20 when the commercial power is cut off or the high-voltage direct-current power module 10 fails, so as to play a role of emergency power supply, ensure the power supply reliability of the power supply system 1 and further ensure the working stability of the data center.
In the embodiment of the present disclosure, the number of each battery pack 21 can be flexibly configured according to the system requirement and the battery freshness, and as long as the voltage level of the battery pack 21 meets the requirement, the dc bus 1a can be accessed through the converting unit 22.
The battery pack 21 may include a plurality of batteries connected in series, and the degree of freshness or the size of the plurality of batteries may be the same or different. For example, the battery pack 21 may be composed of a mixture of new lead-acid batteries, old lead-acid batteries, new lithium batteries, old lithium batteries, and the like.
It can be understood that, in the case that the converting unit 22 is in the input flow direction, the direct current transmitted to the direct current bus 1a by the high voltage direct current power supply module 10 is transmitted to the battery pack 21 through the converting unit 22, so that the battery pack 21 is in the charging state. When the converter unit 22 is in the output flow direction, the dc power output from the battery pack 21 is transmitted to the dc bus 1a via the converter unit 22 and supplies power to the load device, so that the battery pack 21 is in a discharge state.
In one particular example, the conversion unit 22 may be a bidirectional direct current/direct current Converter (DC/DC Converter). The bidirectional DC/DC converter can realize bidirectional flow of DC electric energy and regulate the current and/or voltage of the output DC. More specifically, in the case where the bidirectional dc/dc converter is in the output flow direction, that is, in the state where the battery pack 21 is discharged, the bidirectional dc/dc converter may regulate the voltage of the direct current output from the battery pack 21 to the second preset voltage. For example, the voltage output by the battery pack 21 is regulated to a constant voltage dc of 260V, which is a dc voltage between 200V and 300V. In the case where the bidirectional dc/dc converter is in the input flow direction, that is, the battery pack 21 is in the charging state, the bidirectional dc/dc converter may limit the dc current input to the battery pack 21, that is, adjust the input current of the battery pack 21, thereby adjusting the charging current of the battery pack 21.
According to the power supply system 1 for the data center of the embodiment of the present disclosure, by setting the standby power module 20 connected to the dc bus 1a, when the commercial power is cut off or the high voltage dc power module 10 fails, the load device may be powered by the plurality of standby power submodules 20a of the standby power module 20, so that the power supply reliability of the power supply system 1 is improved, and the working stability of the data center using the power supply system 1 is improved.
Furthermore, by providing the conversion unit 22 in the backup power supply sub-module 20a, the output voltage of each battery pack 21 in the discharge state can be uniformly adjusted to the second preset voltage, so that the battery pack 21 can be composed of a plurality of batteries with different ages, for example, all the old batteries or old and new batteries can be used, and the output voltage of the battery pack 21 can be ensured within the voltage regulation range of the conversion unit 22. Therefore, the power supply system 1 of the embodiment of the present disclosure realizes the reuse of the old battery, and meets the complex and variable requirements such as capacity expansion, thereby reducing the equipment cost and facilitating the construction of a low-carbon and environment-friendly data center.
In one embodiment, the second predetermined voltage is less than the first predetermined voltage.
In one specific example, the first preset voltage may be 270V, and the second preset voltage may be 260V.
It can be understood that, by setting the output voltage of each standby power supply sub-module 20a to be less than the output voltage of the high-voltage dc power supply module 10, in the case of normal power supply of the utility power supply and normal operation of the high-voltage dc power supply module 10, although the converting unit 22 is in the output flow direction, the battery pack 21 does not supply power to the load device through the dc bus 1a, that is, the battery pack 21 is not in the discharge state. Under the condition that the commercial power supply is abnormal or the high-voltage direct-current power supply module 10 works abnormally, the output voltage of the high-voltage direct-current power supply module 10 cannot reach the first preset voltage, and under the condition that the output voltage of the high-voltage direct-current power supply module 10 is smaller than or equal to the second preset voltage, the standby power supply submodule 20a supplies power to the load equipment through the direct-current bus 1a, namely, the battery pack 21 is in a discharge state at the moment.
Through the embodiment, under the condition that the commercial power is cut off or the high-voltage direct-current power supply module 10 works abnormally, the battery pack 21 of the standby power supply module 20 can automatically supply power to the load device, so that the control logic of the discharge of the standby power supply module 20 is simplified, the discharge instantaneity of the standby power supply module 20 is improved, the seamless connection of the main power supply and the standby power supply is realized, and the continuous and stable operation of the electric equipment of the data center is ensured.
In one embodiment, the backup power module 20 further includes a protocol conversion unit for converting a default communication protocol of each battery in the battery pack 21 into a preset communication protocol.
When the battery pack 21 uses batteries of different specifications, the default communication protocol of the batteries differs depending on the manufacturer of the batteries of different specifications, and therefore it is difficult to ensure that each battery in the battery pack 21 can communicate with the management module 30.
In a specific example, a default communication protocol of a certain battery in the battery pack 21 is a CAN bus (Controller Area Network) protocol, a preset communication protocol adopted by the management module 30 may be a Modbus communication protocol (a serial communication protocol), and the protocol conversion unit is configured to convert the CAN bus protocol into the Modbus communication protocol to implement communication between the battery pack 21 and the management module 30.
With the above embodiment, the battery pack 21 may employ a plurality of batteries of different specifications, and communication between the battery pack 21 and the management module 30 is realized. Thereby, the configuration flexibility of the battery pack 21 is improved, so that the compatibility of the power supply system 1 is improved, which is advantageous for further reducing the equipment cost of the power supply system 1.
In one embodiment, the power supply system 1 further comprises a management module 30, the management module 30 being in communication with the battery pack 21 and the transformation unit 22. The management module 30 is configured to: collecting the working parameters of the battery pack 21 and sending a switching signal to the conversion unit 22 corresponding to the battery pack 21. The management module generates a corresponding switching signal according to the operating parameter of the battery pack 21, and the switching signal is used to switch the conversion unit 22 corresponding to the battery pack 21 from an output flow direction to an input flow direction.
The Management module 30 may employ a Battery Management System (BMS). The management module 30 communicates with each battery pack 21 and each transformation unit 22 of the standby power sub-module 20a to receive the operation parameters of each battery pack 21 and send control signals to the transformation unit 22 according to the operation parameters of the battery pack 21 to control the transformation unit 22 to switch to the input flow direction or the output flow direction and/or control the output current and the output voltage of the transformation unit 22.
The operating parameter of the battery pack 21 may include at least one of a current parameter, a voltage parameter, an internal resistance parameter, a temperature parameter, and a capacity parameter.
In a specific example, when any one of the battery packs 21 is in a discharging state, the management module 30 controls the conversion unit 22 corresponding to the battery pack 21 to switch from the output flow direction to the input flow direction according to the collected voltage parameter of the battery pack 21 when the voltage parameter is less than or equal to the preset voltage threshold value, so as to charge the battery pack 21.
In other examples of the present disclosure, the management module 30 may further control the conversion unit 22 corresponding to any battery pack 21 to switch to the input flow direction or the output flow direction, or control the output current of the conversion unit 22 in the input flow direction according to the current parameter, the internal resistance parameter, the temperature parameter, or the capacity parameter of the battery pack 21.
According to the above embodiment of the present disclosure, the management module 30 is provided to communicate with each battery pack 21 and the conversion unit 22, and the management module 30 can control the current flow direction of the corresponding conversion unit 22 according to the operating parameter of the battery pack 21, thereby realizing the control of charging or discharging the battery pack 21. Therefore, real-time monitoring of the operating parameters of the plurality of battery packs 21 is achieved, and the switching of the operating states of the battery packs 21 can be achieved by controlling the conversion units 22 corresponding to the battery packs 21, so that the controllability of the operating modes of the plurality of standby power supply sub-modules 20a is improved, and the power supply reliability of the power supply system 1 is further improved.
In one embodiment, the operating parameters of the battery pack 21 include capacity parameters. Management module 30 is further configured to:
when the capacity parameter of any of the battery packs 21 in the discharge state meets the first threshold condition, a switching signal is transmitted to the conversion unit 22 corresponding to the battery pack 21. The switching signal is used to switch the conversion unit 22 corresponding to the battery pack 21 from the output flow direction to the input flow direction.
Illustratively, the first threshold condition may be 95% of the nominal capacity of the battery pack 21. When the capacity parameter of any battery pack 21 in the discharge state is less than or equal to 95% of the rated capacity of the battery pack 21, the management module 30 sends a switching control signal to the conversion unit 22 corresponding to the battery pack 21 to switch the conversion unit 22 from the output flow direction to the input flow direction, so that the high-voltage direct-current power supply module 10 supplies power to the battery pack 21 through the direct-current bus 1a to enable the battery pack 21 to enter the charge state.
Through the above embodiment, when the capacity parameter of the battery pack 21 meets the preset condition, the battery pack 21 can be charged by controlling the current flow direction of the converting unit 22, thereby ensuring that the capacity of the battery pack 21 is maintained in a usable state, and improving the power supply stability of the standby power module 20.
In one embodiment, when the capacity parameter of any battery pack 21 in the charging state meets the preset capacity value, the management module 30 sends a switching signal to the conversion unit 22 corresponding to the battery pack 21, so that the conversion unit 22 corresponding to the battery pack 21 is switched from the input flow direction to the output flow direction, thereby stopping charging the battery pack 21 and avoiding overcharging the battery pack 21.
In one embodiment, the operating parameters of the battery pack 21 include voltage parameters. Management module 30 is further configured to:
when the voltage parameter of any of the battery packs 21 in the discharge state satisfies the second threshold condition, a switching signal is transmitted to the conversion unit 22 corresponding to the battery pack 21. The switching signal is used to switch the conversion unit 22 corresponding to the battery pack 21 from the output flow direction to the input flow direction.
For example, the calibrated voltage parameter of the battery pack 21 may be 200V to 300V, and the second threshold condition may be 180V. When the voltage parameter of any battery pack 21 in the discharge state is less than or equal to 180V, the management module 30 sends a switching control signal to the conversion unit 22 corresponding to the battery pack 21, so that the conversion unit 22 switches from the output flow direction to the input flow direction, and the high-voltage direct-current power supply module 10 supplies power to the battery pack 21 through the direct-current bus 1a, so that the battery pack 21 enters the charge state.
Through the above embodiment, when the voltage parameter of the battery pack 21 meets the preset condition, the battery pack 21 can be charged by controlling the current flow direction of the converting unit 22, thereby ensuring that the capacity of the battery pack 21 is maintained in a usable state, and improving the power supply stability of the standby power module 20.
In one embodiment, the operating parameters of the battery pack 21 include temperature parameters. Management module 30 is further configured to:
and sending a current adjusting signal to the conversion unit 22 corresponding to the battery pack 21 when the temperature parameter of any battery pack 21 in the charging state meets the preset temperature range. The management module generates a corresponding current adjusting signal according to the temperature parameter of the battery pack 21, and the current adjusting signal is used for adjusting the output current value of the conversion unit 22 corresponding to the battery pack 21 in the input flow direction.
Illustratively, the preset temperature range may be-10 ℃ to 60 ℃. In the case that the temperature of any battery pack 21 in the charging state is too high, i.e. the temperature parameter is close to the upper limit value of the preset temperature range of 60 ℃, the current value transmitted to the battery pack 21 by the conversion unit 22 is controlled to be reduced, so as to alleviate the situation that the temperature of the battery pack 21 is too high due to the too large charging current of the battery pack 21, and make the temperature of the battery pack 21 approach the middle value of the preset temperature range. In the case that the temperature of the temperature parameter of any one of the battery packs 21 in the charging state is too low, i.e., the temperature parameter is close to the lower limit value of the preset temperature range of-10 ℃, the current value supplied to the battery pack 21 by the control converting unit 22 is increased to increase the charging current of the battery pack 21 and increase the temperature rise of the battery pack 21, and the temperature of the battery pack 21 approaches the middle value of the preset temperature range.
The preset temperature range may be set according to an actual normal operating temperature range of the battery pack 21, which is not specifically limited in the embodiment of the present disclosure.
Through the above embodiment, the temperature parameter of the battery pack 21 can be monitored in real time while the battery pack 21 is charged, and the temperature of the battery pack 21 is controlled within a reasonable range, so that the charging stability of the battery pack 21 is improved, and the service life of the battery pack 21 is prolonged.
In one embodiment, management module 30 is further configured to:
when the temperature parameter of any one of the battery packs 21 in the charged state does not conform to the preset temperature range, a stop signal is transmitted to the conversion unit 22 corresponding to the battery pack 21. The stop signal is used to stop the operation of the conversion unit 22 corresponding to the battery pack 21.
Illustratively, in the case that the temperature parameter of any one of the battery packs 21 in the charging state is smaller than the lower limit value of the preset temperature range or larger than the upper limit value of the preset temperature range, the conversion unit 22 corresponding to the battery pack 21 is controlled to stop operating, so as to stop charging the battery pack 21.
Therefore, when the temperature of the battery pack 21 is abnormal, the conversion unit 22 corresponding to the battery pack 21 is controlled to stop working, so that the charging of the battery pack 21 can be stopped in time, thereby avoiding damage to the battery pack 21 due to overhigh or overlow temperature, and being beneficial to prolonging the service life of the battery pack 21.
In one embodiment, an on-off switch 40 is disposed between the conversion unit 22 and the dc bus 1a, and the on-off switch 40 is used for switching the on-off state between the standby power supply submodule 20a and the dc bus 1 a.
The on-off switch 40 may be applied to various technical solutions known to those skilled in the art now and in the future, as long as the conversion unit 22 can be connected to or disconnected from the dc bus 1a, which is not specifically limited in this disclosure.
In other examples of the present disclosure, an on-off switch 40 may be provided between the conversion unit 22 and the battery pack 21 to switch an on-off state between the conversion unit 22 and the battery pack 21.
With the above embodiment, the on-state of the standby power supply submodule 20a and the dc bus 1a can be disconnected by the on-off switch 40, so as to perform operations such as maintenance, installation, or maintenance on the battery pack 21.
In one embodiment, each backup power sub-module 20a further includes a sub-management module 30 in communication with the management module 30, the sub-management module 30 being configured to collect operating parameters of the battery pack 21 and transmit the operating parameters of the battery pack 21 to the sub-management module 30.
For example, the operation parameters of the battery pack 21 collected by the sub-management module 30 may include at least one of a current parameter, a voltage parameter, an internal resistance parameter, a temperature parameter, and a capacity parameter.
Further, the sub-management module 30 is also in communication with the corresponding conversion unit 22 of the battery pack 21, and controls the current flow direction of the corresponding conversion unit 22 according to the collected operating parameters of the battery pack 21, so as to switch the charging state and the discharging state of the battery pack 21.
Through the above embodiment, the sub-management module 30 can implement corresponding control over the transformation unit 22, so that the operational stability and reliability of the standby power supply sub-module 20a are further ensured through dual control of the management module 30 and the sub-management module 30.
