Detailed Description
The technical solution of the present application is further described in detail with reference to the drawings and specific embodiments of the specification.
As shown in fig. 1, the present embodiment provides an electric power system including:
a first type power module 110 for supplying power to a first type load, wherein the first type power module 110 comprises:
a first transformer 111 connected to an external power source for transforming a voltage provided by the external power source;
an Uninterruptible Power Supply (UPS) 112 connected to the rear end of the first transformer 111;
a second type power module 120 for supplying power to a second type of load, wherein the second type power module 120 includes:
and a second transformer 121 for transforming the voltage provided by the external power source.
The power system provided by the embodiment is provided with two types of power modules for supplying power to the load. The two types of power modules have different structures, configuration parameters and power supply modes.
The structural differences can be embodied in: the first type of power module 110 and the second type of power module 120 may include different electronic components, for example, the first type of power module 110 may have a UPS112 relative to the second type of power module 120.
The configuration parameters may be different in that: the first type of power module 110 and the second type of power module 120 each include a transformer, but include different types of transformers, and/or the first type of power module 110 and the second type of power module 120 include different capacities of transformers, and so on.
The power supply mode can be embodied in different ways: the first type power module 110 supplies power to the first type load through the UPS, and the second type power module 120 does not include the UPS112, but directly supplies power to the second type load after transforming a voltage provided by an external power source through the second transformer 121.
In some embodiments, the first type power module 110 includes a first transformer 111 and a UPS112 connected to the first transformer 111, and the UPS112 may directly supply power to the first type load.
The external power source connected to the first transformer 111 may be mains power.
In this way, when the power system supplies power, the first type power module 110 and the second type power module 120 can be flexibly deployed according to the type of the load to be connected. The second type of power module 120 saves at least the UPS112 relative to the first type of power module 110, thereby reducing at least the number of UPSs 112 and the hardware cost of the UPS112 when two power modes are set in the power system relative to a single power system including only the first type of power module 110.
In this embodiment, the second transformer 121 of the second type current module is directly connected to the second type load through the power line, and switching devices such as STS and/or ATS are not required to be provided due to the distributed power supply design. Thus, the power system provided by the embodiment also saves switching devices such as STS and/or ATS.
In some embodiments, the first type of load comprises: and the input load is powered by double power supplies such as IT or network. The IT loads include, but are not limited to: various IT devices.
The second type of load comprises: a first refrigeration load. At this point, the first type of power module is dedicated to powering the IT load, while the second type of power module is dedicated to powering the first refrigeration load.
In other embodiments, the first type of load comprises: an IT load and a second refrigeration load for providing refrigeration to the IT load.
In some embodiments, the first-type load includes N IT loads, and 2N first-type power modules respectively supply power to the N IT loads; and 2 first-class power modules supply power to one path of IT load.
At this time, the second type of load includes: and the N +1 paths of first refrigeration loads respectively supply power to the first refrigeration loads through the N +1 second power models.
For example, if N is 4, the first-type load includes 4 IT loads, and 8 first-type power modules respectively supply power to 4 cooling loads, where one of the IT loads is supplied with power by 2 first-type power modules. Meanwhile, the second type of load includes N +1 paths of the first refrigeration load. And one path of the first refrigeration load is used for refrigerating one path of IT load. Thus, the N +1 paths of first refrigeration loads share one path of backup refrigeration load. And if one path of refrigeration load is abnormal, the first refrigeration load of the backup path is started.
In other embodiments, the first type of load may have a refrigeration load, which is referred to as the second refrigeration load in this embodiment.
In addition, the second type of load is provided with a backup cooling load of the second cooling load, and such a load may be referred to as a third cooling load in this embodiment.
The first type of refrigeration load is one of any refrigeration load. These refrigeration loads may be fans or the like that provide refrigeration for IT loads.
In other embodiments, the second type of load comprises:
the second type of load comprises: and the third refrigeration load is used for performing refrigeration backup on the second refrigeration load and the office operation load.
In some embodiments, the second type of load may include some non-IT loads in addition to the third cooling load, for example, the non-IT loads may include, but are not limited to, office operation loads. In some embodiments, the second type of load may include any other load that is not powered by the UPS112, in addition to the third refrigeration load.
It is worth noting that: the second refrigeration load of the first class of loads and the third refrigeration load of the second class of loads may be directed to the same refrigeration appliance. If the power supply of the first-class power module 110 is abnormal, the refrigeration equipment A connected to the first-class current module is abnormal in refrigeration; at this time, if the refrigeration equipment a is further connected to the second type power module 120, the second type power module 120 is started to start supplying power to the refrigeration equipment a, the power supply abnormality of the refrigeration equipment a is removed, and the refrigeration equipment a can supply power normally again. In this way, through the introduction of one of the second-type power modules 120, the N +1 power supply of the refrigeration load is realized under the condition that the refrigeration load is not increased.
In some embodiments, the first transformer 111 comprises:
the first input port is connected with an external power supply and used for receiving power supply of the external power supply;

and the first voltage transformation module is respectively connected with the first input port and the first output port and used for converting the input voltage provided by the external power supply into the required output voltage and outputting the output voltage from the first output port.
In other embodiments, if the first type of load further comprises a second refrigeration load, the first converter 111 further comprises:
the second output port is directly connected with a third refrigeration load in the first class of loads and used for supplying power to the second refrigeration load;
the first voltage transformation module is respectively connected with the first input port, the first output port and the second output port, and is configured to convert an input voltage provided by the external power supply into a required output voltage and output the output voltage from the first output port and the second output port.
In some embodiments, the second transformer 121 includes:
the second input port is connected with an external power supply and used for receiving power supply of the external power supply;
the third output port is directly connected with the first refrigeration load or the third refrigeration load in the second type of load and used for supplying power to the first refrigeration load or the third refrigeration load in the second type of load;
and the second voltage transformation module is respectively connected with the second input port and the third output port, and is used for converting the input voltage provided by the external power supply into the required output voltage and outputting the required output voltage to the first refrigeration load or the third refrigeration load through the third output port.
In other embodiments, the second transformer 121 further comprises:
and a fourth output port, connected to the rear end of the second transformer module, and connected to a non-IT load or a non-UPS 112 power supply load in the second class of loads, for transmitting the output voltage provided by the second transformer module to the non-IT load or the non-UPS 112 power supply load.
In other embodiments, the capacity of the first transformer 111 is greater than the capacity of the second transformer 121.
The first transformer 111 needs not to be provided with the second transformer 121 having a large capacity because IT needs to supply power to the first type load having a large power consumption, such as the IT load, and the capacity of the first transformer 111 is set to be larger, and the second type load is a load having a low power consumption including the second type load. In the embodiment, the capacity of the second transformer 121 is lower than that of the first transformer 111, so that on one hand, the size of the second type power module 120 can be reduced, and the hardware cost of the second type power module 120 can be reduced.
In some embodiments, the first power module 110 further comprises:
one end of the first power distribution device is connected to the first transformer 111, and the other end of the first power distribution device is directly connected to the IT load and the second refrigeration load of the first type of load.
The power distribution equipment may include various forms of power distribution devices, such as a Switch Board (SB).
The first distribution device may be used for the provision of power provided by the first transformer 111; for example, the power provided by the first transformer 111 is distributed to the IT loads and another portion of the power is provided to the second cooling loads. The power or capacity of the first transformer 111 is not less than the sum of the power of the IT load and the second cooling load.
In other embodiments, the first type of load comprises: one IT load and two of the second refrigeration loads;
the two first-class power modules 110 are configured to supply power to the same IT load of the first-class loads, and the two first-class power modules 110 supply power to different second cooling loads of the first-class loads.
The two first type power modules 110 power the same IT load, thus forming a 2N backup of the IT load power.
Meanwhile, two second refrigeration loads are configured for one IT load, so that the second refrigeration loads for refrigerating the IT load are synchronously switched when the first type power module 110 for switching the power supply of the IT load is switched.
If the second refrigeration load is abnormal in refrigeration, the second type power module 120 can be controlled to start to supply power, so that the third refrigeration load enters a working state and can replace the abnormal second refrigeration load to start refrigeration; thus, a backup of N +1 is achieved for the refrigeration load.
Therefore, under the conditions of simple structure and few used devices of the power system, the IT load and the refrigeration load still respectively realize 2N backup and N +1 backup, and simultaneously ensure the power supply reliability of the power system.
In some embodiments, as shown in fig. 2, the first power module 110 further includes:
a first generator 113 connected in parallel with the external power source for generating power when the external power source is abnormally supplied;
and/or the presence of a gas in the gas,
the second type of power module 120 further comprises:
and a second generator 122 connected in parallel with the external power source and configured to generate power when the external power source is abnormally supplied.
In the present embodiment, a generator is disposed in each of the first type power module 110 and/or the second type power module 120; the generator may generate power to provide pre-transformation power input to the first transformer 111 and/or the second transformer 121 instead of the external power source when the external power source is abnormal.
In some embodiments, the first generator 113 and the second generator 122 may be the same generator. In still other embodiments, the first generator 113 and the second generator 122 are different generators, for example, the power generated by the first generator 113 is greater than the power generated by the second generator 122.
As shown in fig. 3, the present embodiment provides a control method of an electric power system, the method including:
step S110: the method comprises the steps of controlling a first type power module comprising a first transformer and an Uninterruptible Power Supply (UPS) connected to the rear end of the first transformer to supply power to a first type load;
step S120: the control module comprises a second transformer and a second type power module for supplying power to a second type load.
The control method of the power system provided in this embodiment may be a control method for controlling the current system.
In summary, the method provided by the present embodiment is to control the power system provided with the aforementioned first power module and second power module.
In this embodiment, the step S110 and the step S120 do not have a certain sequence, and the step S110 may be executed before the step S120, the step S120 may be executed before the step S110, or the step S110 and the step S120 may be executed.
In the embodiment of the invention, the first type of load is a main power supply load of the power system; or, the first type of load is a load with higher power consumption than the second type of load, and is a core power consumption module for supplying power to the power system.
In some embodiments, the step S110 may include: supplying power to a first type of load including an IT load using a first type of power module; and/or, the step S120 may include: and supplying power to a second type of load comprising the first refrigeration load by using a second type of power module.
In this embodiment, all refrigeration loads are powered by the second type of power module.
In other embodiments, the step S120 may include:
and if a second refrigeration load contained in the first type of load is abnormal, controlling the second type of power module to supply power to a third refrigeration load of the second type of load, wherein the third refrigeration load is a backup of the second refrigeration load.
In this case, the second type of load may be a load that needs to be supplied with power under certain circumstances. For example, when a second refrigeration load in the first class of loads has a working fault or is abnormally powered, the second power module is controlled to supply power to a third refrigeration load in the second class of loads to realize power supply backup.
In this embodiment, if the second refrigeration load is in an abnormal operation, the abnormal operation includes, but is not limited to, at least one of the following:
a failure of the second refrigeration load itself;
the power supply to the second cooling load is abnormal.
In short, if the second refrigeration load is abnormal, IT indicates that the second refrigeration load may not be able to perform normal refrigeration, and thus the second type power module is controlled to start power supply to the third refrigeration load, and thus the third refrigeration load enters an operating state to replace the abnormal third refrigeration load for refrigeration so as to maintain the temperature of the environment where the IT load is located.
In some embodiments, the method further comprises:
if the first-class load exceeds the current load capacity of the power system after capacity expansion, increasing the first-class power modules contained in the power system;
and the expanded load is supplied with power through the increased first class current load.
In this embodiment, since the power system includes the first-type power module and the second-type power module, when capacity expansion of the load is performed, the first-type power module or the second-type power module may be flexibly added according to the type of the load.
For example, if the first type of load exceeds the current load capacity of the power system, the first type of power module included in the power system may be added; and the second type of power module is not increased accordingly. And the more the first type of power modules are, the one the second type of power modules are maintained, the ratio of the power consumption capacity of the first type of load to the power supply capacity of the whole power system is continuously increased, and therefore the effective power supply efficiency of the power system is improved.
Several specific examples are provided below in connection with any of the embodiments described above:
example 1:
as shown in fig. 4, the present example provides an electric power system including: power module B and power module R; the power module B comprises a transformer, a low-voltage distribution B and a UPS; one output port of the low-voltage distribution cabinet is directly connected with the refrigeration equipment, and the other output port of the low-voltage distribution cabinet B is connected with the IT load through the UPS.
The two power modules B supply power for one path of IT load, and 2N backup of IT power supply is realized.
Meanwhile, each power module B supplies power to one path of refrigeration equipment, so that if the IT load is switched to the power module B supplying power, the refrigeration equipment for refrigerating the IT load is also switched.
The power module R includes: a transformer and a low-voltage distribution cabinet R; one output port of the low-voltage power distribution cabinet B directly supplies power to the refrigeration equipment, and the other output port of the low-voltage power distribution cabinet B supplies power to an office operation load.
IT can be seen that in the power system provided in this example, at least any one or more of the refrigeration equipment, the IT load, and the office operation load are directly connected to the output port of the power distribution cabinet or the output port of the UPS, and no switching device such as an ATS or STS is provided on the power transmission line.
In the power system shown in fig. 4, the capacity of the transformer of the power module B is 2000kVA as an example; for example, the capacity of the transformer in power module R is 400kVA, so the capacity of the transformer in power module R is smaller than the capacity of the transformer in power module B.
The power module B (corresponding to the aforementioned first type of power module) includes a transformer capacity that is not less than the power consumption capacities of the IT load and a cooling device (corresponding to the aforementioned cooling load).
The power module R (corresponding to the aforementioned second type of power module) contains a transformer having a capacity not less than the sum of the capacities of the office operation load and the cooling equipment (corresponding to the aforementioned cooling load).
Example 2:
based on example 1, the present example provides another power system. The power system adopts a set of (2) small-capacity transformers, and a refrigerating device which is independently used for redundancy (+1) is split to supply power, so that two sets of +1 redundant refrigerating devices are formed; and 2N UPS power supplies are respectively arranged below each other set (2) of transformers, meanwhile, the refrigerating equipment is divided into 2 sets and respectively supplied with power by different transformers, the refrigerating capacity of the refrigerating equipment is matched with the IT load capacity of the UPS belt below the set of transformers, and thus a module is formed. And the refrigeration equipment adopts distributed power supply, so that the design of ATS can be omitted, and the cost is saved.
The power supply of N +1 and the redundancy of the refrigeration equipment are formed by supplying power to an additional set of refrigeration equipment through a single transformer. Therefore, each main power supply module can be continuously copied and expanded (as long as the commercial power capacity is enough).
Based on the above design change, from the utilization ratio of commercial power capacity, the patent scheme can improve the commercial power utilization ratio and the output of IT capacity. In summary, the power system provided in this example changes the 2N refrigeration equipment usage to N +1, and the excess power is used to generate IT loads.
And the ATS design is removed, and the complexity and the redundancy of the system are reduced.
The refrigeration and IT power supply architecture is optimized, and the capacity expansion can be continuously copied after the modular design.
After the 2N refrigeration equipment power consumption is changed into N +1, the utility power capacity can be more fully utilized, and more IT loads can be generated.
Example 3:
as shown in fig. 5, the present example provides an electric power system including:
a parallel operation power distribution cabinet of the generator; in fig. 5 the letter G indicates a high voltage generator;
a commercial power high-voltage power distribution cabinet A;
a commercial power high-voltage power distribution cabinet B;
power module B, including but not limited to power module B1 and power module B2 shown in FIG. 5;
the power modules R include the power module R1 and the power module R2 shown in fig. 5.
The power module B is a main power supply module; the power module R is a refrigeration power supply module.
When power supply expansion is performed, only the expansion of the main power supply module is required, for example, the expansion is performed from the main power supply module 1 and the main power supply module 1-1 corresponding to the power module B1 and the power module B2 to the main power supply module 1-N; on the other side, the main power supply module corresponding to the power module R2 for cooling and supplying power expands from the main power supply module 2 to the main power supply module 2-1 … … to the main power supply module 2-N.
As can be seen from fig. 5, the power system is divided into two parts, namely a left part and a right part, which can be referred to as a first part and a second part. A (small capacity) transformer supplies a redundant set of refrigeration equipment. According to the capacity of the transformer of the power system and the power consumption of various loads shown in fig. 5, the power consumption capacity ratio can be calculated as follows:
load to transformer capacity ratio: (1440+360)/2000 ═ 90%;
load to transformer capacity ratio: 360/400-90%;
the ratio of IT power consumption to refrigeration equipment power consumption is as follows: 1440:720(360x 2) ═ 2: 1.
Since the power supply module can be expanded to N continuously, the ratio of IT capacity to power capacity becomes 1440 × N/2000 × 2N +400, which is 35.3% when N is 5.
The power system of this example can increase the available IT capacity by 15% over the power systems provided in the related art by optimizing the refrigeration load distribution and modular grouping on a cost-effective basis, also at utility capacity.
The IT load and the refrigeration equipment are combined on the same transformer, but on the capacity of the capacity N, because no independent redundant transformer is responsible for the power supply of the redundant part of the refrigeration equipment, the legend is that 8 refrigeration equipment correspond to 4 paths of IT loads, and the corresponding relation is 7:4, therefore, the number of the transformers and the electrical switches can be reduced, and the occupied space of the electrical equipment is optimized.
Example 4:
as shown in fig. 6, the present example provides an electric power system including:
the first kind of power module specifically includes: the IT power module 1, the IT power module 2 and the like are special modules for supplying power to IT loads;
the second kind of power module specifically includes: and the refrigeration power module is specially used for supplying power to the refrigeration load.
The IT power module includes: transformer, voltage distribution and UPS, utilize UPS directly to supply power to IT load. The two IT power modules are used for supplying power to one IT load to form 2N power supply.
The refrigeration power module includes: transformer and low voltage distribution, etc. to supply power to the refrigeration load directly through low voltage distribution.
All refrigeration equipment are dispersed to different transformers independently and are supplied with power in a distributed mode N +1, and the power is used as a set of refrigeration power module and corresponds to a plurality of sets of IT power supply modules, so that refrigeration equipment with large monomer capacity (the number of the refrigeration equipment is relatively small) can be used, and the occupied space of the refrigeration equipment can be optimized. For the case of two-way powering, N +1 may be an even number.
