[0002] With the continuous development of technology, uninterruptible power supply (UPS) is increasingly used in various fields, especially in situations where high reliability of power supply is required. Therefore, the training of UPS operation and maintenance personnel is particularly important. Traditional UPS operation training mainly relies on paper or electronic documents and occasional opportunities to operate real equipment, but these methods often have many limitations and shortcomings.

[0003] At present, UPS operation training is mainly carried out in two ways: one is by reading the "UPS User Manual" or training materials provided by the manufacturer, including PPT, short videos, etc.; the other is the simple "UPS Standard Operating Procedures" written by UPS users themselves. These materials provide basic operating guidelines for operators. However, the accumulation of actual operating experience mostly relies on paper talk, and the opportunities to actually operate UPS are very limited.

[0029] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention.

[0030] The present invention uses a programmable logic controller (PLC)\touch screen programming software to develop all functions of a simulated UPS. The program can be simulated and run on a computer, downloaded to a PLC\touch screen, or deployed to the cloud for use. It can simulate and operate on the touch screen without the need for actual external input and output of physical quantities.

[0031] The present invention adopts PLC programming, which has better real-time response than other third-party simulation software. For example, when the user clicks the interface button, the pop-up speed of its window is very fast. Its internal logic cycle execution speed is very fast, and it can usually reach a response time of milliseconds or even microseconds. This efficient real-time response capability ensures that in industrial automation applications, PLC can quickly adjust and control the production process. PLC is usually equipped with a special hardware accelerator or processor, and these hardware optimizations make PLC more efficient in processing complex logic and arithmetic operations. Compared with third-party software simulation that relies on general-purpose processors, PLC's hardware support provides it with stronger real-time performance. PLC programming environment usually provides a rich function library and instruction set, which is optimized specifically for industrial control needs.

[0038] Specifically, Figure 3 The figure shows a schematic diagram of the operation interface of the virtual simulation system of the uninterruptible power supply device provided by the present invention. Taking a certain brand of UPS-5000E parallel system as an example, in the simulation system, 4 UPS operation objects are included.

Entering the operation interface of the system, there are 4 UPS simulation operation objects in the screen, and each UPS simulation operation object includes buttons such as the main input switch, bypass input switch, maintenance bypass switch, internal output switch, battery switch, common functions and system information.

[0039] At the bottom of the interface is the alarm display window, which is used to generate corresponding prompts based on errors in the operating environment, such as prompting low battery voltage protection, or when an error is clicked or a switch that should be clicked is not clicked, prompting an alarm that the corresponding switch is not closed, etc.

[0040] Confirm that all UPS switches (including maintenance bypass switch) are in the off state, adjust the UPS simulated input voltage to 400V (line voltage), adjust the simulated output power to below 500KW, and set the UPS output voltage to 220V and frequency to 50HZ (setting is required for the first simulation, the output voltage and frequency are mainly used for synchronous static bypass, so that the system output can switch smoothly).

[0041] S220: Based on the initialized virtual simulation system of the uninterruptible power supply device, receive a power on / off instruction for any uninterruptible power supply simulation operation object, and dynamically display the power on / off simulation result in an interface according to the power on / off instruction.

[0042] According to a virtual simulation method of an uninterruptible power supply device provided by the present invention, an on / off instruction for any uninterruptible power supply simulation operation object is received, and an interface dynamic display of the on / off simulation result is performed according to the on / off instruction, which specifically includes: receiving a switch on instruction for turning on a corresponding switch in an on / off simulation module 110 for any uninterruptible power supply simulation operation object, generating a switch on input parameter according to the switch on instruction, running a simulation on process of the corresponding switch according to the switch on input parameter, obtaining a switch on output parameter, and performing an interface dynamic display of the switch on simulation result according to the switch on output parameter; receiving a power on function selection instruction, generating a switch on input parameter according to the power on function selection instruction, and performing an interface dynamic display of the switch on simulation result according to the switch on output parameter; Select instructions to run the single-machine inverter startup process or the parallel inverter startup process, and dynamically display the startup operation simulation results on the interface; or receive a shutdown function selection instruction, simulate the operation of the single-machine inverter shutdown process or the parallel inverter shutdown process according to the shutdown function selection instruction, and dynamically display the shutdown operation simulation results on the interface; receive a switch closing instruction for the corresponding switch in the shutdown on / off simulation module 110 for any uninterruptible power supply simulation operation object, generate a switch closing input parameter according to the switch closing instruction, run the simulation of the shutdown process of the corresponding switch according to the switch closing input parameter, obtain the switch closing output parameter, and dynamically display the switch closing simulation result on the interface according to the switch closing output parameter.

[0043] Specifically, there are 4 ways to turn the machine on and off.

[0044] (1) Simulate the startup operation of a single UPS: In the interface of the operation simulation system, select any UPS operation object, turn on the UPS static bypass input or main input switch, the UPS starts, the static bypass input changes color (such as from gray to green), and the rectifier starts with a delay. Click the interface to turn on the battery switch, and the battery starts charging with a delay. Click the interface to turn on the UPS internal output switch, click UPS common functions, select single-machine inverter startup, click confirm, the UPS switches from static bypass to inverter operation, and the single-machine startup operation is completed.

[0045] (2) Simulate single UPS shutdown operation: In the operation simulation system interface, select any UPS operation object, click the UPS common function button, select the single inverter shutdown option, click confirm, the UPS inverter stops running and switches to static bypass operation (if there is a load, the maintenance bypass switch can be turned on). Then click to turn off the UPS internal output switch, click to turn off the battery switch, click to turn off the main switch, click to turn off the static bypass input, and the UPS shutdown process simulation is completed.

[0046] (3) Simulate UPS parallel system startup operation: Click to turn on the static bypass input of each UPS, and each UPS will start up, and the static bypass input will turn green; click to turn on the main input switch of each UPS, and the UPS rectifier will start with a delay; click to turn on the battery switch of each UPS, and the UPS battery will be charged with a delay; click to turn on the internal output switch of each UPS, click the common function button on any UPS and select the parallel inverter startup option, click confirm in the pop-up window, and the UPS will uniformly switch from static bypass to inverter operation. You can also realize parallel startup by selecting the single inverter startup operation of each UPS according to the load size.

[0047] (4) Simulate UPS parallel system shutdown operation: Click the common function button on any UPS and select the parallel inverter shutdown option. Click Confirm in the pop-up window. The UPS will switch from inverter to static bypass operation (if there is a load, the maintenance bypass switch can be turned on). Click to turn off each UPS internal output switch, click to turn off each UPS battery switch, click to turn off each UPS bypass input switch, and click to turn off each UPS main input switch. You can also select each UPS single inverter shutdown operation to achieve parallel shutdown according to the load size.

[0048] Receive a fault simulation instruction for any uninterruptible power supply simulation operation object, and dynamically display the fault simulation result interface according to the fault simulation instruction.

[0049] According to a virtual simulation method of an uninterruptible power supply device provided by the present invention, a fault simulation instruction for any uninterruptible power supply simulation operation object is received, and an interface dynamic display of the fault simulation result is performed according to the fault simulation instruction, which specifically includes: receiving a fault simulation instruction for any uninterruptible power supply simulation operation object; generating corresponding fault simulation input parameters according to the fault simulation instruction and transmitting them to the fault simulation module 120, the fault simulation module 120 simulating the corresponding uninterruptible power supply fault process according to the fault simulation input parameters to obtain corresponding fault simulation output parameters; and dynamically displaying the fault simulation result on the interface according to the fault simulation output parameters.

[0050] Specifically, UPS fault simulation: Common UPS fault settings include power module fault, rectifier unit fault, inverter unit fault and battery pack fault. By clicking the fault simulation button to trigger the fault, the UPS will respond accordingly. Clicking the power module fault and battery pack fault triggers a general alarm, which does not affect the UPS operation. Clicking the rectifier unit fault will cause the UPS to switch to battery discharge mode to ensure continuous power supply; clicking the inverter unit fault will cause the faulty UPS to exit inverter operation for parallel systems; if it is a single UPS system, it will switch to static bypass operation.

[0051] There are also some UPS response simulations under certain conditions: When the UPS output power exceeds 125% of the rated power, the system will delay switching to static bypass operation to protect the equipment.

[0052] If the UPS input voltage exceeds the range of ±15%, the UPS will switch to battery discharge mode; when the voltage returns to normal, the UPS will automatically switch back to rectifier operation.

[0053] During battery discharge, if the voltage is lower than 420V, the UPS will switch to static bypass operation; for a parallel system, if the battery discharge voltage of a single UPS is lower than 420V, the UPS will exit operation.

[0054] When the maintenance bypass is closed during UPS inverter operation, a UPS system fault will be triggered, causing the UPS to shut down due to inverter failure.

[0055] If the load exceeds 125% of the rated value when the UPS is switched or reduced, the system will switch to static bypass to protect the equipment.

[0056] Receive the charge / discharge instruction for any uninterruptible power supply simulation operation object, and dynamically display the interface of the charge / discharge simulation result according to the charge / discharge instruction.

[0057] According to a virtual simulation method of an uninterruptible power supply device provided by the present invention, a charge / discharge instruction for any uninterruptible power supply simulation operation object is received, and an interface of a charge / discharge simulation result is dynamically displayed according to the charge / discharge instruction, which specifically includes: receiving a charge switch on instruction for any uninterruptible power supply simulation operation object, generating a charge switch on input parameter according to the charge switch on instruction and transmitting it to a charge / discharge simulation module 130, wherein the charge / discharge simulation module 130 simulates the uninterruptible power supply charging process according to the charge switch on input parameter, obtains a charge output parameter, and an interface of a charge simulation result is dynamically displayed according to the charge output parameter; or receiving a discharge switch on instruction for any uninterruptible power supply simulation operation object, generating a discharge switch on input parameter according to the discharge switch on instruction and transmitting it to the charge / discharge simulation module 130, wherein the charge / discharge simulation module 130 simulates the uninterruptible power supply discharge process according to the discharge switch on input parameter, obtains a discharge output parameter, and an interface of a discharge simulation result is dynamically displayed according to the discharge output parameter.

[0058] Specifically, the UPS discharge and equalization charge functions are simulated.

[0059] In terms of UPS discharge function simulation: When the main output switch of the UPS is disconnected, or the manual discharge test button of the UPS is pressed, or the automatic discharge button of the UPS is turned on, the system will trigger the discharge process of the UPS battery. During the battery discharge process, if the battery discharge voltage drops below 420V, the system will perform corresponding protection actions to ensure safety. In particular, when the automatic discharge button of the UPS is turned on, this will activate the periodic discharge test function of the UPS to verify the performance and life of the battery.

[0060] In terms of UPS equalization function simulation: When the manual equalization charge switch or automatic equalization charge switch of the UPS is turned on, the equalization charge function of the UPS will be started. In the automatic equalization charge mode, the system will determine the start conditions of equalization charge or whether periodic equalization charge is required, and automatically switch from equalization charge to floating charge when appropriate. In the manual equalization charge mode, manual operation is required to switch from equalization charge to floating charge, which provides more flexibility and allows users to adjust the charging strategy according to actual conditions.

[0061] Receive a mode switching instruction for any uninterruptible power supply simulation operation object, and dynamically display the interface of the mode switching simulation result according to the mode switching instruction.

[0063] Specifically, UPS mode switching simulation.

[0064] Multiple operation modes are implemented in the UPS simulation system, and these modes can be switched freely, including rectification main circuit operation mode, bypass operation mode, battery discharge mode and maintenance bypass mode.

[0065] Rectification main circuit operation mode: UPS mainly converts AC power into DC power through a rectifier to supply the load.

[0066] Bypass operation mode: When a fault occurs inside the UPS or maintenance is required, the system will automatically or manually switch to bypass operation mode. At this time, the AC power is directly supplied to the load to ensure a stable power supply.

[0067] Battery discharge mode: In the event of a utility power outage, the UPS will switch to battery discharge mode, providing uninterrupted power to the load through the built-in battery pack.

[0068] Maintenance bypass mode: When the UPS needs to be repaired or maintained, it can be switched to maintenance bypass mode. At this time, the AC power is directly supplied to the load through the maintenance bypass, and the main components inside the UPS are isolated to facilitate safe maintenance work.

[0069] Receive the protection simulation instruction for any uninterruptible power supply simulation operation object, and dynamically display the protection simulation result interface according to the protection simulation instruction.

[0070] According to a virtual simulation method of an uninterruptible power supply device provided by the present invention, a protection simulation instruction for any uninterruptible power supply simulation operation object is received, and an interface of a protection simulation result is dynamically displayed according to the protection simulation instruction, specifically comprising: receiving a protection simulation instruction for any uninterruptible power supply simulation operation object; generating protection simulation input parameters according to the protection simulation instruction and transmitting them to a protection simulation module 150, wherein the protection simulation module 150 simulates the protection process of the uninterruptible power supply according to the protection simulation input parameters to obtain protection simulation output parameters; and dynamically displaying an interface of the protection simulation result according to the protection simulation output parameters.

[0071] Specifically, the protection simulation function of the virtual simulation method of the uninterruptible power supply device is very comprehensive, mainly including voltage over-limit protection, power over-limit protection, operation error protection and other aspects.

[0072] In terms of voltage overlimit protection, the system can simulate the protection mechanism of the uninterruptible power supply when the voltage is too high or too low. When the voltage exceeds the safe range, the simulation system will trigger the corresponding protection measures to ensure that the power supply equipment is not damaged, and dynamically display this protection process through the interface.

[0073] Power over-limit protection is the monitoring and protection of power supply output power. When the power output of the power supply exceeds its rated value, the simulation system will respond in time and simulate the actual protection action, such as reducing the output power or cutting off the power supply, to avoid equipment overload damage. This process will also be dynamically displayed on the interface for users to understand intuitively.

[0074] In addition, the method also includes an operation error protection function. When the user makes an error operation, such as setting the power supply parameters incorrectly or executing an improper operation process, the simulation system will identify these errors and simulate corresponding protection measures. It can not only prevent damage to the equipment in actual operation, but also help users recognize and correct their own wrong operations through dynamic feedback of the interface.

[0075] Through these specific protection simulation functions, a comprehensive simulation and demonstration is provided for the operation of the uninterruptible power supply, which greatly enhances the user's understanding and mastery of the operation of the power supply equipment.

[0076] Receive a parameter viewing instruction for any uninterruptible power supply simulation operation object, and dynamically display the interface of the parameter viewing simulation result according to the parameter viewing instruction.

[0077] According to a virtual simulation method of an uninterruptible power supply device provided by the present invention, a parameter viewing instruction for any uninterruptible power supply simulation operation object is received, and an interface of the parameter viewing simulation result is dynamically displayed according to the parameter viewing instruction, which specifically includes: receiving a parameter viewing instruction for any uninterruptible power supply simulation operation object; generating parameter viewing input parameters according to the parameter viewing instruction and transmitting them to a parameter viewing simulation module 160, wherein the parameter viewing simulation module 160 simulates the uninterruptible power supply parameter viewing process according to the parameter viewing input parameters to obtain parameter viewing output parameters; and dynamically displaying the interface of the parameter viewing simulation result according to the parameter viewing output parameters.

[0078] Specifically, the UPS system contains a variety of key parameters, which reflect the working status and performance of each UPS module, including rectification parameters, battery parameters, inverter parameters, static bypass parameters, etc.

[0079] Rectification parameters: mainly reflect the working status of the rectifier. When the rectifier is not working, its input voltage, input current, input power and input frequency are all displayed as 0. However, once the rectifier starts running, these parameters will be displayed in real time and dynamically adjusted as the load power of the simulator changes. This dynamic change not only shows the working efficiency of the rectifier, but also provides users with real-time feedback on the power input status.

[0080] Battery parameters: reflect the status and performance of the UPS's built-in battery and are key indicators for evaluating whether the UPS can continue to provide power when the city power is interrupted.

[0081] Inverter parameters: reflect the efficiency and quality of the inverter in converting DC power into AC power, which is crucial to ensure that the UPS outputs stable and high-quality power.

[0082] Static bypass parameters: Pay attention to the working status of the bypass system. The bypass system is an important backup path to ensure continuous power supply when the UPS main system fails.

[0083] The realization of UPS simulation function mainly includes two core parts: PLC program design and touch screen configuration design. The following are the implementation steps: (1) First, clarify and formulate the simulation function requirements of UPS.

[0084] (2) Next, design the UPS configuration screen based on the proposed UPS simulation functions. In this step, select appropriate graphic elements to build an intuitive and user-friendly operation interface to ensure that users can complete all functions of the same UPS parallel system through one main screen, thereby greatly simplifying the simulation operation process.

[0085] (3) Then, design the PLC program according to the simulation function of the UPS. In this link, the core task is to build the action function block of the UPS. It should be noted that different series of UPS may require the design of different function blocks to meet their unique functional requirements. It is necessary to accurately determine the input and output parameter quantities of each function block and ensure that the actions of each UPS in the parallel system can be realized through these function blocks.

[0086] (4) Finally, associate the variables in the configuration screen with the variables in the PLC program. This enables dynamic changes in the screen content, thereby reflecting the operating status of the UPS system in real time.

[0087] The present invention effectively solves the programming limitations of paper and electronic training materials. Taking the UPS startup operation as an example, traditional training materials can often only provide a fixed operation sequence, such as closing the static bypass switch first, then closing the output switch or the main input switch, etc. However, on the UPS operation simulation system of the present invention, users can perform the startup operation just like operating a real UPS, thereby obtaining a more realistic experience.

[0088] The UPS operation simulation system provided by the present invention greatly increases the UPS operation opportunities, allowing users to practice operation at any time without relying on external input and output points. In addition, specific models or multiple models of UPS simulators can be provided according to user needs.

[0089] In actual UPS operation, operators are often reluctant to perform unconventional operations due to certain risks. However, on the UPS operation simulation system provided by the present invention, users can safely perform various operation attempts, because incorrect operations will not cause real losses, but will trigger the corresponding protection mechanism of the UPS.

[0090] Taking a certain brand of UPS as an example, it provides two buttons: single-machine inverter on / off and parallel inverter on / off. The use of these two buttons must be carefully selected, otherwise accidents may occur. Especially when the load exceeds the bearing capacity of a single UPS, shutting down each UPS one by one may cause the last UPS to automatically switch to static bypass; similarly, when starting up, if the load is too large, the first UPS may also automatically switch to static bypass operation, resulting in startup failure. These complex and high-risk operation scenarios are difficult to try in a real UPS environment, but on the UPS operation simulation system provided by the present invention, users can safely experience and understand these operations.

[0091] In addition, the UPS operation simulation system can easily realize scenarios that are difficult to trigger in real UPS, such as UPS input over-limit, UPS overload, etc. Through the simulation of these scenarios, users can have a deeper understanding of the properties and characteristics of UPS, so as to be more handy in actual operation.
