[0002] A power distribution room is usually set up in an enterprise to distribute power to all electrical equipment in the enterprise. When supplying power to large electrical equipment such as motors, the electric energy output from the power distribution room needs to pass through a series of power transformation and distribution systems first, so that the electric energy can be transmitted to the motor through the transmission line. In this process, there is a certain loss of electric energy. Therefore, it is necessary to provide a power integration system that can not only supply power to large electrical equipment, but also realize on-site storage of electric energy, and then localize the power supply to improve energy utilization and achieve motor energy saving, and realize storage and distribution integration.

[0025] A distribution room is usually set up in an enterprise to distribute power to all electrical equipment in the enterprise. In existing solutions, enterprises are often powered by external power grids or external energy storage systems, and for safety reasons, the distribution room is usually a certain distance away from large electrical equipment. When supplying power to large electrical equipment such as motors, the electric energy output by the distribution room needs to pass through a series of power transformation and distribution equipment in order to transmit the electric energy to the motor through the transmission line. In this process, there is a certain loss of electric energy, which reduces the energy utilization rate. Furthermore, if the distribution room and the centralized energy storage system are damaged, the entire enterprise will be out of power, and the maintenance cost will be too high, which will cause a relatively large safety hazard to some key core equipment. Therefore, it is necessary to provide a power integration system that can not only supply power to large electrical equipment, but also store electricity locally on site to improve the power supply stability of core electrical equipment and reduce the energy consumption of electrical equipment.
[0026] See also Figure 1 The present application provides a power integration system 100, which includes: a connecting copper bus 110, a distribution subsystem 120, a storage subsystem 130 and a fireproof partition wall 140, wherein the connecting copper bus 110 is used to be electrically connected to an external power grid; the distribution subsystem 120 is electrically connected to the connecting copper bus 110 to distribute the electric energy input from the external power grid to an external power-consuming device 210 to supply power to the power-consuming device 210; the storage subsystem 130, the connecting copper bus 110 and the distribution subsystem 120 are connected in series in sequence, and the storage subsystem 130 includes an energy storage device 131 for storing electric energy and supplying power to the distribution subsystem 120; the fireproof partition wall 140 is arranged between the distribution subsystem 120 and the storage subsystem 130, and is used to separate the storage subsystem 130 and the distribution subsystem 120.
[0027] It can be understood that the energy storage subsystem 130, the connecting copper bus 110 and the distribution subsystem 120 are connected in series in sequence, and the external power grid can supply power to the external electrical equipment 210 through the connecting copper bus 110 and the distribution subsystem 120, and the external power grid can also supply power to the energy storage device 131 of the energy storage subsystem 130 through the connecting copper bus 110, and the energy storage device 131 then supplies power to the external electrical equipment 210 with the stored electrical energy from the connecting copper bus 110 and the distribution subsystem 120.
[0028] In this embodiment, the power integration system 100 includes a connecting copper bus 110, a distribution subsystem 120 and a storage subsystem 130. The external power grid can be electrically connected to the distribution subsystem 120 by connecting the copper bus 110 to supply power to the distribution subsystem 120. Compared with the solution in which the energy storage system supplies power to the distribution room of the entire enterprise, the power integration system 100 provided in the embodiment of the present application has a smaller load and can be set near the external power equipment 210, so that the distribution subsystem 120 directly distributes the electric energy input from the external power grid to the external power equipment 210, without the need for a transformer to transform the voltage input from the external power grid. In this process, the conversion of electric energy can be reduced, which is beneficial to reducing the energy loss of the power integration system 100 during the power distribution process and improving energy utilization. Furthermore, if some components in the distribution subsystem 120 and the storage subsystem 130 of the power integration system 100 are damaged, it will only affect the external power-consuming equipment 210 electrically connected to the distribution subsystem 120, and the impact area is relatively small, which is conducive to improving the efficiency of troubleshooting problems, reducing maintenance costs, and improving the performance of the power integration system 100. Furthermore, during the off-peak period, the external power grid can not only directly supply power to the distribution subsystem 120, but also be electrically connected to the storage subsystem 130 by connecting the copper bus 110, so as to input the excess power of the external power grid into the energy storage device 131. During the peak period, the power integration system 100 preferentially uses the power stored in the energy storage device 131, and the energy storage device 131 supplies power to the distribution subsystem 120, and the distribution subsystem 120 distributes the power stored in the energy storage device 131 to the external power-consuming equipment 210. The power integration system 100 can utilize the price difference between the off-peak period and the peak period to provide sufficient power to the external power-consuming equipment 210 while reducing the power supply cost, thereby improving the performance of the power integration system 100. On the other hand, it also reduces the power loss of the external power grid during the off-peak period, reduces the power load of the external power grid during the peak period, and improves the performance of the power integration system 100. Furthermore, the power integration system 100 also includes a fireproof partition wall 140, and the fireproof partition wall 140 is arranged between the storage subsystem 130 and the distribution subsystem 120. When one of the storage subsystem 130 and the distribution subsystem 120 has a dangerous event such as a fire due to excessive temperature, the fireproof partition wall 140 can protect the other, thereby improving the safety performance of the power integration system 100. The power integration system 100 has high energy utilization and energy-saving effects. It can not only distribute electricity to external power-consuming equipment 210 efficiently, but also realize localized power storage. While reducing the electricity costs of external power-consuming equipment 210, it improves the stability of the power integration system 100 in supplying power to the power-consuming equipment 210 and reduces the energy consumption of the power-consuming equipment 210.
[0029] It can be understood that in the terminology of the present application, "valley time period" refers to the time period when there are fewer electricity users and the external power grid has sufficient power supply, and "peak time period" refers to the time period when there are more electricity users and the external power grid has insufficient power supply. Usually, the electricity price during the peak time period is higher than the electricity price during the valley time period.
[0030] Optionally, the power integration system 100 includes a grid-connected component 170 , and the grid-connected component 170 is used to electrically connect the power distribution subsystem 120 and the power storage subsystem 130 .
[0031] In some embodiments, the energy storage subsystem 130 further includes an energy management unit 132 , which is electrically connected to the energy storage device 131 and is used to monitor the storage capacity of the energy storage device 131 . The energy management unit 132 is also used to manage the charging and discharging of the energy storage device 131 .
[0032] It can be understood that the energy management unit 132 is used to manage the charging and discharging of the energy storage device 131 , and the energy management unit 132 can be used to control the energy storage device 131 to start charging, stop charging, start discharging or stop discharging.
[0033] In this embodiment, the energy management unit 132 is used to monitor the storage capacity of the energy storage device 131. When the storage capacity of the energy storage device 131 is large, the energy management unit 132 can control the energy storage device 131 to start discharging to provide power to the power distribution subsystem 120. When the storage capacity of the energy storage device 131 is small, the energy management unit 132 can control the energy storage device 131 to stop discharging and control the energy storage device 131 to start charging. When the energy storage device 131 is fully charged, the energy management unit 132 can control the energy storage device 131 to stop charging. The energy management unit 132 manages the charging and discharging of the energy storage device 131 according to the storage capacity of the energy storage device 131 to avoid overcharging or over-discharging of the energy storage device 131, and can avoid accidents such as fire caused by excessive temperature of the energy storage device 131, which is conducive to improving the safety performance of the power integration system 100. In addition, the energy management unit 132 can realize intelligent management of the charging and discharging of the energy storage device 131, so that the energy storage device 131 can store full electric energy during the off-peak period and supply power to the distribution subsystem 120 during the peak period, thereby improving the utilization rate of energy.
[0034] Optionally, the energy management unit 132 is further used to monitor the power consumption of the energy storage device 131 in different time periods to form a power consumption curve of the energy storage device 131 according to the power consumption, so as to control the charging and discharging process of the energy storage device 131.
[0035] It can be understood that the energy management unit 132 is used to control the charging power, charging time period, discharging power and discharging time period of the energy storage device 131.
[0036] In some embodiments, the energy storage subsystem 130 further includes a metering unit 133, which is located between the energy distribution subsystem 120 and the energy storage device 131, and the energy distribution subsystem 120, the metering unit 133 and the energy storage device 131 are connected in series in sequence; the metering unit 133 is used to measure the amount of electricity flowing through the metering unit 133.
[0037] Optionally, in some embodiments, the metering unit 133 is a bidirectional meter.
[0038] It can be understood that the amount of electricity flowing through the metering unit 133 includes the amount of electricity flowing from the connecting copper bus 110 to the energy storage device 131, that is, the amount of electricity stored in the energy storage device 131 by the external power grid, and the amount of electricity flowing through the metering unit 133 also includes the amount of electricity flowing from the energy storage device 131 through the connecting copper bus 110 and then flowing to the distribution subsystem 120, that is, the amount of power supplied by the energy storage device 131 to the distribution subsystem 120.
[0039] In this embodiment, the power distribution subsystem 120, the metering unit 133 and the energy storage device 131 are connected in series in sequence, and the metering unit 133 is used to measure the amount of electricity flowing through the metering unit 133 to monitor the power usage and power consumption of the energy storage device 131, so as to obtain the storage capacity of the energy storage device 131, and further, to facilitate the energy management unit 132 to manage the charge and discharge of the energy storage device 131. The metering unit 133 can dynamically measure the amount of electricity flowing through the metering unit 133 to dynamically detect the charge and discharge state of the energy storage device 131, strengthen the monitoring and management of the charge and discharge process of the energy storage device 131, and is conducive to improving the safety performance of the power integration system 100.
[0040] In some embodiments, the storage subsystem 130 also includes a protection unit 134, which is located between the distribution subsystem 120 and the energy storage device 131. The distribution subsystem 120, the protection unit 134 and the energy storage device 131 are connected in series in sequence. When there is an overvoltage between the distribution subsystem 120 and the energy storage device 131, the protection unit 134 protects the energy storage device 131.
[0041] It can be understood that, in the terminology of the present application, "overvoltage" refers to a voltage whose root mean square value of an AC voltage exceeds 10% of a rated voltage, and the rated voltage refers to an optimal voltage for the energy storage device 131 to work normally for a long time.
[0042] In this embodiment, the energy storage subsystem 130 also includes a protection unit 134. When there is an overvoltage between the energy storage device 131 and the connecting copper bus 110, the energy storage device 131 will be damaged. When the protection unit 134 identifies the overvoltage, it can discharge the strong current generated by the overvoltage to the outside, and limit the overvoltage to the voltage range that the energy storage device 131 can withstand, so that the energy storage device 131 is not damaged by the overvoltage, thereby ensuring the function of the energy storage device 131 to store electrical energy and supply power to the distribution subsystem 120, which is beneficial to prolonging the service life of the power integration system 100.
[0043] Optionally, the protection unit 134 is a surge protection device. In the terminology of the present application, "surge" refers to a momentary overvoltage.
[0044] It can be understood that when the protection unit 134 and the metering unit 133 are simultaneously arranged between the power distribution subsystem 120 and the energy storage device 131, the protection unit 134 and the metering unit 133 are arranged at intervals; in some embodiments, the protection unit 134 is arranged closer to the energy storage device 131 than the metering unit 133; in other embodiments, the protection unit 134 is arranged farther away from the energy storage device 131 than the metering unit 133.
[0045] In some embodiments, the power distribution subsystem 120 includes a switch assembly 121 and at least one power distribution component 122 , and the connecting copper bus 110 , the switch assembly 121 and the power distribution component 122 are sequentially connected in series.
[0046] In the power distribution subsystem 120 provided in this embodiment, the connecting copper bar 110, the switch assembly 121 and the power distribution component 122 are connected in series in sequence. In other words, the switch assembly 121 is arranged between the connecting copper bar 110 and the power distribution component 122, and the switch assembly 121 is used to control the on and off of the electrical connection circuit of the connecting copper bar 110 and the power distribution component 122 to achieve power distribution to the external power equipment 210. When the switch assembly 121 is in a closed state, the connecting copper bar 110 and the power distribution component 122 are in a conducting state. During the peak power period and when the power storage device 131 has a relatively full storage capacity, the power distribution component 122 can receive the electric energy stored in the energy storage device 131 and supply power to the external power equipment 210; during the valley power period or when the power storage device 131 has insufficient storage capacity, the power distribution component 122 can receive the electric energy input from the external power grid and supply power to the external power equipment 210. When the switch assembly 121 is in an open state, the connecting copper bus 110 and the power distribution component 122 are in a disconnected state, and the power distribution component 122 cannot supply power to the external power-consuming device 210. The switch assembly 121 implements control of the power distribution program of the power distribution subsystem 120.
[0047] In some embodiments, there are multiple distribution components 122, and the switch assembly 121 includes a main switch 1211 and multiple sub-switches 1212. One end of the main switch 1211 is electrically connected to the connecting copper bus 110, and the other end of the main switch 1211 is electrically connected to the multiple sub-switches 1212 respectively. The end of each sub-switch 1212 facing away from the main switch 1211 is electrically connected to one distribution component 122, and different sub-switches 1212 are electrically connected to different distribution components 122.
[0048] It can be understood that multiple sub-switches 1212 are connected in parallel.
[0049] It can be understood that the sub-switches 1212 correspond one-to-one to the power distribution components 122 .
[0050] In this embodiment, the opposite ends of the main switch 1211 are connected to the connecting copper bar 110 and the sub-switch 1212, respectively. When the main switch 1211 and the sub-switch 1212 are both in the closed state, the connecting copper bar 110 and the power distribution components 122 corresponding to the sub-switch 1212 are turned on, so that the power distribution components 122 can receive power from the external power grid or the energy storage device 131 to supply power to the external power-consuming device 210. When the main switch 1211 or the sub-switch 1212 is in the open state, the connecting copper bar 110 and the power distribution components 122 corresponding to the sub-switch 1212 are in the disconnected state, and the power distribution components 122 cannot supply power to the external power-consuming device 210. The main switch 1211 and the sub-switch 1212 cooperate to realize independent control of each power distribution component 122, thereby improving the system adjustability of the power distribution subsystem 120 and further improving the performance of the power integration system 100.
[0051] In the terminology of the present application, "plurality" means greater than or equal to two, and may be but is not limited to two, three, four, five, six or seven, etc.
[0052] In some embodiments, the power distribution component 122 includes at least one sub-assembly (not shown), and the sub-assembly is selected from one of a circuit breaker, a contactor, and a relay.
[0053] As used herein, "at least one" means one or more.
[0054] In this embodiment, the power distribution component 122 includes at least one sub-accessory, which can be determined according to the type of the external power-consuming equipment 210. The at least one sub-accessory is used to protect and control the external power-consuming equipment 210, so as to transmit the electric energy transmitted by the storage subsystem 130 or the external power grid to the sub-accessory, and then distribute it to the power-consuming equipment 210, so as to power the power-consuming equipment 210.
[0055] In some embodiments, the power integration system 100 also includes a fireproof box 150, which encloses a receiving cavity 151. The fireproof partition wall 140 is arranged in the receiving cavity 151 to separate the receiving cavity 151 into a first receiving sub-cavity 152 and a second receiving sub-cavity 153. The first receiving sub-cavity 152 is used to receive the electronic storage system 130, and the second receiving sub-cavity 153 is used to receive the electronic distribution system 120.
[0056] It can be understood that the fireproof partition wall 140 is connected to the fireproof box 150 .
[0057] In this embodiment, the fireproof partition wall 140 divides the fireproof box 150 into a first receiving sub-chamber 152 and a second receiving sub-chamber 153, so as to divide the receiving chamber 151 into two mutually isolated chambers. When a fire occurs in one of the storage sub-system 130 or the distribution sub-system 120 due to excessive temperature or the like, the storage sub-system 130 and the distribution sub-system 120 can be prevented from affecting each other. In addition, the fireproof box 150 can also protect the external electrical equipment 210 around the power integration system 100, thereby improving the safety performance and usability of the power integration system 100.
[0058] See also Figure 2 In some embodiments, the energy storage subsystem 130 further includes a liquid cooler 160 , and the liquid cooler 160 is used to dissipate heat from the energy storage device 131 .
[0059] In this embodiment, the liquid cooler 160 is disposed in the first receiving sub-cavity 152 to dissipate heat for the energy storage device 131, so that the energy storage device 131 can be kept within a normal temperature range, thereby preventing the energy storage device 131 from being overheated due to dissipating more heat during the charging and discharging process, thereby helping to extend the service life of the energy storage device 131, and then helping to extend the service life of the power integration system 100.
