[0001] The present application relates to the technical field of production power supply, and in particular to a power supply system for a production workshop. Background Art

[0002] With the continuous improvement of production requirements and production safety, in addition to production equipment, production workshops are also equipped with supporting video surveillance systems, emergency lighting systems, access control systems, fire protection systems and other workshop equipment. In order to ensure that the workshop equipment can continue to operate in the event of a power outage, it is necessary to provide backup power supply for each workshop equipment to ensure that each workshop equipment can operate safely and reliably in the event of a power outage.

[0003] At present, production workshops generally use UPS (Uninterruptible Power Supply) for backup power supply. However, due to the limitations of battery technology, UPS load is small. When there are a large number of workshop equipment, UPS can only provide emergency power supply in a short time and cannot meet the safe downtime requirements of workshop units, so there are certain safety risks.

[0004] To solve the above problems, production workshops with major safety risks are generally equipped with diesel generator sets to achieve backup power supply through diesel generator sets. However, diesel generator sets need to be manually started by technicians on site in the workshop according to the size of the critical operating load. When an emergency power outage occurs, if the diesel generator set is not started in time, there will be major safety risks.

[0034] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0035] In some embodiments, Figures 1 to 3 As shown, the present application provides a production workshop power supply system, including: a UPS device 100, a diesel generator device 200, a backup power supply on-off device 300 and a control device 400. Among them, the UPS device 100 refers to a power supply device based on an uninterruptible power supply, including at least one uninterruptible power supply. The diesel generator device 200 refers to a power supply device based on a diesel generator set, including at least one diesel generator set. It can be understood that the number of uninterruptible power supplies and the number of diesel generator sets can be determined according to actual conditions, and this document does not impose specific restrictions on this. In some examples, the diesel generator device 200 may include multiple diesel generator sets, and the diesel generator sets may have a data transmission function and have the ability to automatically start and stop according to instructions. In other examples, the uninterruptible power supply may have an Internet of Things function and support the same frequency, voltage and phase function.

[0036] The backup power supply on-off device 300 is used to control the electrical connection between the UPS device 100 and the workshop equipment, and the electrical connection between the diesel generator device 200 and the workshop equipment. Among them, the workshop equipment refers to the equipment in the production workshop that needs to be connected to the backup power supply, including but not limited to production equipment (such as machine tools, lifting equipment, welding equipment, etc.), video monitoring systems, emergency lighting systems, fire protection systems, access control systems, etc. In some examples, the UPS device 100 and the diesel generator device 200 of the present application can adopt a three-phase four-wire system and support 380V / 220V workshop equipment.

[0037] The backup power supply on-off device 300 is respectively connected to each uninterruptible power supply and each diesel generator set, and is used to connect the workshop equipment. It can be understood that when the backup power supply on-off device 300 is in a closed state, the uninterruptible power supply and the diesel generator set can supply power to each workshop equipment. When the backup power supply on-off device 300 is in an open state, the uninterruptible power supply and the diesel generator set cannot supply power to the workshop equipment.

[0038] The control device 400 refers to a device with data processing and control functions, and is the operation and analysis center of the power supply system of the production workshop, and can be used to undertake the operation of the uninterrupted algorithm model. The specific implementation of the control device 400 can be determined according to the actual method, and this document does not make specific restrictions on this. In some examples, the control device 400 may include a central processing unit.

[0039] The control device 400 is respectively connected to the backup power supply on-off device 300, each uninterruptible power supply and each diesel generator set. The control device 400 can determine whether the production workshop has a power outage. When the power outage is detected in the production workshop, the UPS device 100 and the diesel generator set are started respectively, and a closing control signal is sent to the backup power supply on-off device 300 to control the backup power supply on-off device 300 to close. In this case, the UPS device 100 and the diesel generator 200 can supply power to the workshop equipment to achieve uninterrupted power supply.

[0040] Specifically, when the UPS device 100 includes multiple uninterruptible power supplies and multiple uninterruptible power supplies are needed for backup power supply, in order to enable each uninterruptible power supply to output voltages with the same frequency, voltage and phase to ensure the quality of the backup power supply, the control device 400 can start at least one uninterruptible power supply according to a preset UPS start-up sequence.

[0041] In some examples, the control device 400 may first power on an uninterruptible power supply and obtain the voltage, frequency and phase of the first powered-on uninterruptible power supply as a reference. Then, the control device 400 may power on the second uninterruptible power supply, and the two uninterruptible power supplies are connected to the network for information synchronization and coordination until the second powered-on uninterruptible power supply is successfully synchronized with the first powered-on uninterruptible power supply in voltage, frequency and phase. If the second powered-on uninterruptible power supply is successfully synchronized, the control device 400 may power on the third uninterruptible power supply and synchronize the third powered-on uninterruptible power supply according to the aforementioned process, and so on, until the power-on synchronization of M uninterruptible power supplies is completed and the cloudification of multiple uninterruptible power supplies is realized. Among them, M can be the preset number of power supplies used.

[0042] For diesel generator sets, since they use AC to supply power externally, in order to reduce disturbances to the power supply network, the diesel generator sets need to be synchronized in phase, frequency, and phase angle first, and then put into use after synchronization. Therefore, when multiple diesel generator sets need to be started, multiple diesel generator sets need to be put into use gradually to avoid causing disorder in the power grid system and damage to equipment in the production workshop.

[0043] Based on this consideration, the control device 400 of the present application can start at least one diesel generator set according to a preset generator start-up number and a preset generator start-up sequence, so as to gradually put the diesel generator sets into the power supply system.

[0044] In some examples, the control device 400 can also be connected to the workshop power supply line switch, protection equipment, electrical instrument and workshop equipment respectively, so as to network the workshop power supply line switch, protection equipment, electrical instrument and workshop equipment to form an uninterruptible power supply system for the production workshop, and uniformly allocate and manage them. The control device 400 can obtain the equipment data of all working equipment in the workshop, and allocate the networked UPS according to the workload of the workshop, and allocate the operation of the workshop generator set according to the power consumption of the entire workshop.

[0045] Furthermore, in some examples, the control device 400 may be connected to the UPS device 100, the diesel generator device 200, the workshop electrical module and the workshop equipment respectively via industrial Ethernet. To ensure disturbance-free power switching, the communication rate of the industrial Ethernet may be less than 10ms.

[0046] It should be noted that the production workshop power supply system provided in this application is not only suitable for production workshops, production plants, and factories, but also for control rooms, information rooms, data centers, monitoring centers and other scenarios with high requirements for power supply stability, and has the advantage of wide applicability.

[0047] In the present application, the UPS device 100 and the diesel generator device 200 can provide emergency power supply that can meet the safety downtime requirements for the workshop equipment. At the same time, the control device 400 can be connected to the backup power supply on-off device 300, each uninterruptible power supply and each diesel generator set respectively, and when a power outage in the production workshop is detected, at least one uninterruptible power supply and at least one diesel generator set are automatically started, and the backup power supply on-off device 300 is automatically controlled to close. In this way, the uninterruptible power supply and the diesel generator set can be put into use as soon as possible, thereby reducing the safety risk of the production workshop.

[0048] In some embodiments, the UPS device 100 may include M+N uninterruptible power supplies connected in parallel, where M is the number of power supplies in use, N is the number of power supplies in reserve, and both M and N are preset positive integers.

[0049] In this embodiment, M+N backup can be achieved, that is, M uninterruptible power supplies are working and N uninterruptible power supplies are standby. When some uninterruptible power supplies in the UPS device 100 fail and the number of uninterruptible power supply failures is not greater than N, the control device 400 can enable the standby uninterruptible power supply to ensure that the power supply of the UPS device 100 is not affected.

[0050] This embodiment can improve the stability of the uninterruptible power supply by adopting the M+N uninterruptible power supply solution. This embodiment can concentrate the uninterruptible power supplies scattered in the production workshop in one production workshop. Since the uninterruptible power supply needs to replace the battery every 3 to 5 years to restore its performance, when the total number of uninterruptible power supplies is reduced, the number of batteries supporting the production workshop is reduced accordingly, thereby reducing maintenance costs.

[0051] In some embodiments, the UPS device 100 may also include multiple static switches, which are connected to multiple uninterruptible power supplies in a one-to-one correspondence, so that the uninterruptible power supplies are connected to the backup power supply on-off device 300 through the static switches. That is, each uninterruptible power supply is connected to its corresponding static switch, and the static switches connected to any two uninterruptible power supplies are not the same static switch. Each static switch is connected to the backup power supply on-off device 300. In this way, when the backup power supply on-off device 300 is closed, the output of the uninterruptible power supply can be connected to the power supply network through the static switch.

[0052] Since the output of the uninterruptible power supply is connected to the power supply network using a static switch, it has the advantage of non-disruptive exit when equipment fails. If the uninterruptible power supply fails after startup, the switching state of the static switch connected to the uninterruptible power supply can be controlled to achieve non-disruptive exit of the faulty uninterruptible power supply, thereby reducing the impact of the faulty uninterruptible power supply on the workshop equipment.

[0053] Furthermore, in one example, the present application can utilize the Internet of Things technology to network multiple uninterruptible power supplies. The control device 400 can be connected to each uninterruptible power supply and each static switch, and obtain UPS information of each uninterruptible power supply. When an uninterruptible power supply fails, the failed uninterruptible power supply or the remaining uninterruptible power supplies can send fault information to the control device 400. The control device 400 can control the remaining normal uninterruptible power supplies to maintain phase-locked synchronization, and redistribute the load of the failed uninterruptible power supply, and automatically take the failed uninterruptible power supply offline from the parallel power supply system after the redistribution is completed.

[0054] In some embodiments, when determining that there is a power outage in the production workshop, the control device 400 detects the current workshop load of the production workshop according to a preset detection cycle, and performs load control on each uninterruptible power supply and each diesel generator set according to the current workshop load.

[0055] Taking into account that the units running in the production workshop are changing dynamically, the usage load of the production workshop (i.e., the workshop load) is also changing dynamically. In order to achieve the stability of the power supply network, reduce the power consumption of the workshop, and extend the power supply time of the backup power supply, this embodiment can dynamically increase or decrease the output load of the UPS device 100 and the diesel generator device 200 (i.e., the power supply load described in other embodiments of the present application).

[0056] Specifically, when it is determined that the production workshop is out of power, the control device 400 can periodically detect the current usage load of the production workshop according to the preset detection cycle and obtain the current workshop load. It can be understood that the cycle length of the preset detection cycle can be determined according to actual conditions, and this application does not impose specific restrictions on this. The control device 400 can detect the current usage load of the production workshop in any manner.

[0057] In one example, the electrical switches and electrical instruments used in the present application may have network transmission functions and remote switching capabilities, and the workshop equipment may have data transmission functions. The control device 400 may periodically collect the working data of each workshop equipment and determine the current usage load of the production workshop accordingly.

[0058] When the current workshop load is obtained, the control device 400 can perform load regulation on each uninterruptible power supply and each diesel generator set accordingly, so as to dynamically control the output load of the UPS device 100 and the diesel generator device 200.

[0059] In one example, when the current workshop load is obtained, the control device 400 can calculate the current power supply load according to the current workshop load, so as to balance the workshop power load and load allocation. It can be understood that the current power supply load is greater than the current workshop load, so that the power supply load has a certain redundancy, thereby reducing the power consumption of the workshop and reducing the safety risk of the production workshop. Exemplarily, the control device 400 can use the current workshop load as the base number and add a certain load loss to obtain the current power supply load. In order to ensure the balance of the workshop load, the control device 400 can use the Laplace algorithm, Fourier algorithm, demand coefficient algorithm, utilization coefficient algorithm and other algorithms of the power system to perform load balancing calculations to obtain the current power supply load.

[0060] When the current power supply load is obtained, the control device 400 can perform load control on each uninterruptible power supply and each diesel generator set according to the current power supply load, the preset UPS start-up sequence and the generator start-up sequence, so as to adjust the output load of the UPS device 100 and the diesel generator device 200 according to the current power supply load.

[0061] In this way, the power supply of the entire workshop can be managed and controlled, and the standby load of each uninterruptible power supply and each diesel generator set can be automatically adjusted according to the load changes of production equipment, saving production costs.

[0062] In some embodiments, the control device 400 is used to obtain the generator status data of each diesel generator set and the UPS status data of each uninterruptible power supply, and input the generator status data and UPS status data into a pre-trained diagnostic expert model to obtain a fault warning diagnosis result.

[0063] In this embodiment, a big data model can be used to form a self-diagnosis expert model, and the expert model can be used to monitor and warn the system itself to improve the operational reliability of the power supply system in the production workshop.

[0064] Specifically, the control device 400 is connected to each diesel generator set and each uninterruptible power supply, and can obtain the generator status data of each diesel generator set and the UPS status data of each uninterruptible power supply. The generator status data can be used to reflect the operating status of the diesel generator set, for example, it can include oil quantity data. The UPS status data can be used to reflect the operating status of the uninterruptible power supply.

[0065] The control device 400 can input each generator status data and each UPS status data into the diagnostic expert model, so that the diagnostic expert model can perform fault diagnosis and fault warning on the production workshop power supply system based on the received generator status data and UPS status data, and output the fault warning diagnosis result. It can be understood that the fault warning diagnosis result can be used to reflect whether there is a fault in the production workshop power supply system and / or whether the production workshop power supply system has a potential fault risk.

[0066] In some embodiments, the diesel generator 200 may include a generator monitoring module to monitor the generator status data of each diesel generator set through the generator monitoring module. Specifically, the generator monitoring module may be connected to the control device 400 to monitor the generator status data of each diesel generator set in real time and send the generator status data to the control device 400.

[0067] It is understandable that the generator monitoring module can be implemented in any manner, and the present application does not impose any specific limitation thereto. For example, the generator monitoring module can monitor the status of the diesel generator set through one or more sensors.

[0068] In some embodiments, the power supply system of the production workshop further includes an interactive terminal, which is connected to the control device 400. In one example, the interactive terminal can be connected to the control state through a signal network provided in the production workshop, and the interactive terminal can be used to run HMI (Human Machine Interface).

[0069] The control device 400 can determine whether the power supply system of the production workshop has a fault and / or whether there is a potential fault risk in the power supply system of the production workshop according to the fault warning diagnosis result output by the diagnostic expert model. If so, the control device 400 can generate a fault alarm message and push the fault alarm message to the interactive terminal to alarm through the interactive terminal. In this way, the workshop management personnel and technicians can be reminded in time to handle the fault, so as to improve the operational reliability of the system.

[0070] Furthermore, the HMI can display the operating status of the power supply system of the production workshop, and support the function of viewing operating data, abnormal alarming, and setting operating parameters. That is, the HMI can receive the system operating parameters set by the workshop management personnel, and can send the system operating parameters to the control device 400, so that the control device 400 performs power supply control based on the system operating parameters.

[0071] In one example, the workshop manager can start the workshop electrical module through the HMI to gradually access the electrical switches, electrical instruments, and electrical comprehensive protection. In addition, the workshop manager can pre-set the UPS start-up sequence, the number of generators to be started, and / or the generator start-up sequence through the HMI.

[0072] In one example, the workshop electrical module can automatically collect information on workshop switches, electrical instruments and protective devices, and monitor the workshop electrical circuit problems in real time based on the collected information, so that timely alarms can be issued when abnormalities occur.

[0073] In some embodiments, the backup power supply on-off device 300 may include at least two on-off modules, namely a main on-off module and a backup on-off module. The main on-off module is respectively connected to the control device 400, each uninterruptible power supply and each diesel generator set, and is used to connect the workshop equipment. The backup on-off module is respectively connected to the control device 400, each uninterruptible power supply and each diesel generator set, and is used to connect the workshop equipment.

[0074] In the event of a power outage in the production workshop, if the main on-off module can work normally, this application can use the main on-off module to power the workshop equipment. In the event of a power outage in the production workshop, if the main on-off module fails, this application can use the backup on-off module to power the workshop equipment. Figure 3 ,exist Figure 3 In the example, the main on-off module may include two circuit breakers arranged on the main power supply line, and the backup on-off module may include two circuit breakers arranged on the backup power supply line.

[0075] In this way, the power supply reliability of the production workshop power supply system can be further improved to further reduce the safety risks of the production workshop.

[0076] In some embodiments, the backup power supply on-off device 300 may also include a plurality of leakage circuit breakers, which are connected to each workshop equipment in a one-to-one correspondence. The leakage circuit breaker is connected between the main on-off module and the workshop equipment, and the leakage circuit breaker is also connected between the backup on-off module and the workshop equipment.

[0077] In this embodiment, a leakage circuit breaker can be configured on each user side, and one leakage circuit breaker is used to control one workshop equipment. When a workshop equipment fails, the leakage circuit breaker connected to the workshop equipment can promptly cut off the faulty equipment from the power supply network to prevent the faulty equipment from affecting the operation of all workshop equipment. In this way, the safety risk can be further reduced.
