Description

Technical Field

[0001] This invention relates to the field of DC power supply technology, specifically a programmable DC power supply process operation parameter adjustment and compensation system. Background Technology

[0002] Programmable DC power supplies are widely used in many fields such as electronic equipment testing, new energy research and development, and aerospace. The accuracy and stability of their output parameters are crucial to the performance evaluation of equipment and the reliable operation of systems.

[0003] In actual operation, programmable DC power supplies are subject to interference from various factors. Changes in ambient temperature can cause the parameters of the internal electronic components of the power supply to drift, thereby affecting the stability of the output voltage and current. Fluctuations in the mains voltage can also directly affect the power supply input, causing the output parameters to deviate from the preset values. In addition, dynamic changes in the load, such as the sudden connection or disconnection of the load, or frequent changes in the load size, can cause instability in the power supply output, resulting in voltage drops or overshoot.

[0004] How to make appropriate adjustments and compensations to the DC power supply based on the real-time operating data of the DC power supply's input and output during operation, so as to make the DC power supply operate more safely and efficiently, is the problem we need to solve. To this end, we now provide a programmable DC power supply process operating parameter adjustment and compensation system. Summary of the Invention

[0005] The purpose of this invention is to provide a programmable DC power supply process operating parameter adjustment and compensation system.

[0006] The objective of this invention can be achieved through the following technical solution: a programmable DC power supply process operating parameter adjustment and compensation system, comprising:

[0007] The DC power supply module includes an input unit, an output unit, and an adjustment unit. The input unit converts external AC power into corresponding DC power, and the output unit connects to the power user to transmit the DC power to the power user. During the process of the output unit outputting DC power to the power user, the adjustment unit dynamically adjusts and compensates the parameters of the output DC power.

[0008] A programmable module is used to preset the basic operating parameters of the DC power supply, including rated current, rated voltage, output loss coefficient, and to construct a dynamic operating model based on the operating data of the DC power supply module.

[0009] The data acquisition module is used to acquire the operating data of the DC power supply module, including the AC power input by the input unit and the current output by the output unit.

[0010] The parameter analysis module is used to analyze the operating status of the DC power supply based on the constructed dynamic operation model, and to determine whether the DC power supply is operating abnormally and whether the output DC power is compatible with the power demand of the user.

[0011] The adjustment and compensation module is used to adjust the operating data of the DC power supply when there is an abnormality in its operation, and to compensate for the DC power output when the DC power output does not match the demand of the power consumption end.

[0012] Furthermore, the process of building a dynamic runtime model using programmable modules is as follows:

[0013] Create corresponding component nodes for each component of the DC power module, and generate corresponding virtual connection lines for each component node according to the connection relationship between each component in the DC power module. Connect each component node through the virtual connection lines to obtain the initial simulation model of the DC power module.

[0014] The obtained operational data is imported into the corresponding component nodes, and a corresponding visualization of data changes is generated in each component node based on the imported operational data.

[0015] Introduce the basic operating parameters of the DC power supply into the visualized data change chart, and generate the corresponding standard data range in the visualized data change chart based on the introduced basic operating parameters of the DC power supply.

[0016] The visualization data change graphs of each component node are imported into the corresponding component node in the initial simulation model, and the simulation is run on each component node to obtain the corresponding dynamic operation model. Based on the constructed dynamic operation model, the operating status of the DC power supply is analyzed.

[0017] Furthermore, a coordinate system of time with respect to the corresponding running data is constructed based on the running data within the corresponding component nodes, and a corresponding change curve is generated based on the running data;

[0018] By mapping each change curve onto a coordinate system, a visual data change graph corresponding to each component node can be obtained.

[0019] Furthermore, for the input unit, the visualization data change map of the component node corresponding to the input unit is marked, and a time window of fixed duration is set in the visualization data change map. The duration of the time window is T, and the time window consists of the current moment and the previous moment with an interval of T from the current moment.

[0020] Current and voltage variation curves within the calibration time window;

[0021] The visual data change graphs corresponding to the input unit include AC current change curves and AC voltage change curves;

[0022] The generated DC voltage change curve and DC current change curve are compared with the corresponding standard data range. If the DC voltage change curve and DC current change curve are within the corresponding standard data range, it indicates that the input unit is operating normally.

[0023] If any point in time or segment of the DC voltage and DC current change curves within the time window exceeds the standard data range, it indicates that the input unit is malfunctioning. In this case, a corresponding input adjustment command is generated and sent to the adjustment compensation module.

[0024] Furthermore, for the output unit, the visualization data change diagram of the corresponding component node of the output unit is marked;

[0025] The system acquires the demand information from the power consumption terminal through the output unit, and generates corresponding demand voltage change curves and demand current change curves in the visualized data change graph based on the demand information from the power consumption terminal.

[0026] Set the data evaluation period within the visualized data change chart;

[0027] The demand voltage change curve and demand current change curve within the data evaluation period are compared with the rated voltage and rated current, respectively. If the voltage corresponding to any point on the demand voltage change curve is higher than the rated voltage, or the voltage corresponding to the demand current change curve is higher than the rated voltage, or the current corresponding to the demand current change curve is higher than the rated current, it indicates that the DC power supply cannot meet the power demand of the user. The corresponding warning information is then generated and sent to the regulating unit. The regulating unit disconnects the output unit from the user based on the warning information.

[0028] If the voltages corresponding to the demand voltage change curves are all not higher than the rated voltage, and the currents corresponding to the demand current change curves are all not higher than the rated current, it means that the DC power supply can meet the power demand of the user. Then, the adjustment and compensation module evaluates the performance degradation of the DC power supply and performs power supply compensation to the user based on the performance degradation of the DC power supply.

[0029] Furthermore, the process by which the adjustment and compensation module evaluates the performance degradation of the DC power supply includes:

[0030] Based on the demand voltage change curve and the demand current change curve, generate the corresponding expected output voltage change curve and expected output current change curve of the DC power supply.

[0031] Based on the output voltage and output current of the obtained output unit, the corresponding actual output voltage change curve and actual output current change curve are generated respectively.

[0032] Then, at the end of each data evaluation cycle, the power supply attenuation coefficient Gs of the DC power supply is obtained;

[0033] Set the power supply attenuation coefficient threshold G0;

[0034] When Gs < G0, it indicates that the DC power supply is functioning normally and no action is required.

[0035] When Gs≥G0, it indicates that the DC power supply performance is degraded, and a power supply compensation command is generated.

[0036] Furthermore, the adjustment and compensation module marks any time point or curve segment of the DC voltage change curve and DC current change curve within the time window that exceeds the standard data range according to the input adjustment command, and obtains the difference between the maximum current value and the maximum voltage value that exceed the standard data range and the standard data range. Based on the obtained difference, the corresponding AC voltage and AC current are adjusted accordingly so that the converted DC voltage and DC current are within the standard data range.

[0037] Furthermore, when the DC power output from the DC power supply is mismatched with the demand at the power consumption end, the adjustment and compensation module performs power supply compensation for the DC power output, which includes:

[0038] Based on the obtained power supply attenuation coefficient of the DC power supply, at the beginning of the next data evaluation cycle, corresponding correction coefficients are generated for the basic operating parameters of the DC power supply.

[0039] The basic operating parameters of the DC power supply are then updated based on the correction coefficient to obtain the updated output loss coefficient.

[0040] Based on the updated output loss coefficient, new expected output voltage change curves and expected output current change curves are generated. Based on the average difference between the actual output voltage change curves and actual output current change curves within the current data evaluation period and the new expected output voltage change curves and expected output current change curves, the corresponding compensation voltage value and compensation current value are obtained. Based on the obtained compensation voltage value and compensation current value, power supply compensation is performed on the power consumption terminal of the DC power supply.

[0041] Compared with the prior art, the beneficial effects of the present invention are:

[0042] By combining the input and output operating data of the DC power supply with its basic operating parameters, a corresponding dynamic operating model is constructed for the DC power supply. This allows for dynamic simulation of the DC power supply's operation. Based on the simulation results, the deviation between the actual and theoretical operating data of the DC power supply's input and output is analyzed, and the basic operating parameters of the DC power supply are corrected. This reduces the probability of the DC power supply being in an abnormal operating state, improving the operational safety of the DC power supply. Simultaneously, based on the difference between the DC power supply's output and the power required by the user, corresponding adaptive power supply compensation is performed at the user end, thereby improving the operating efficiency of the DC power supply. Attached Figure Description

[0043] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments recorded in this invention. For those skilled in the art, other drawings can be obtained based on these drawings.

[0044] Figure 1 This is a schematic diagram of the present invention;

[0045] Figure 2 This is a schematic diagram of the dynamic operation model of the present invention. Detailed Implementation

[0046] The solutions described in the embodiments of the present invention are intended to solve the technical problems of DC power supply operation safety and efficiency in the prior art, and the overall approach adopted is as follows:

[0047] The system acquires the operating data of the DC power supply module and constructs a dynamic operating model based on the basic operating parameters of the DC power supply. The operating status of the DC power supply is analyzed through the constructed dynamic operating model to determine whether the DC power supply is operating abnormally and whether the output DC power is compatible with the power demand. When the DC power supply is operating abnormally, the operating data of the DC power supply is adjusted to ensure that the abnormality of the DC power supply does not affect the power demand. When the output DC power of the DC power supply is not compatible with the power demand of the power demand, the output DC power of the DC power supply is compensated.

[0048] like Figure 1 As shown, the programmable DC power supply process operation parameter adjustment and compensation system includes a DC power supply module, a programmable module, a data acquisition module, a parameter analysis module, and an adjustment and compensation module.

[0049] The DC power supply module includes an input unit, an output unit, and an adjustment unit. In the specific implementation process, the input unit converts the external AC power into the corresponding DC power, and then the output unit connects to the power consumption terminal to transmit the DC power to the power consumption terminal. During the process of the output unit outputting DC power to the power consumption terminal, the adjustment unit dynamically adjusts and compensates the parameters of the output DC power.

[0050] The programmable module is used to preset the basic operating parameters of the DC power supply, which include rated current, rated voltage, and output loss coefficient.

[0051] It is also used to build dynamic operation models based on the operating data of DC power supply modules;

[0052] The data acquisition module consists of several data acquisition terminals, which are used to acquire the operating data of the DC power supply module. The operating data includes the AC power input by the input unit and the current output by the output unit.

[0053] The parameter analysis module is used to analyze the operating status of the DC power supply based on the constructed dynamic operation model, and to determine whether the DC power supply is operating abnormally and whether the output DC power is compatible with the power demand of the user.

[0054] The adjustment and compensation module is used to adjust the operating data of the DC power supply when there is an abnormality in its operation, so that the abnormality of the DC power supply will not affect the power consumption end, and to compensate the DC power output of the DC power supply when the DC power output is not compatible with the power consumption end.

[0055] In another embodiment of the present invention, it is necessary to mark the basic operating parameters and operating data of the DC power supply involved. For example, for the operating data: the AC voltage of the AC power input from outside the input unit is denoted as U. sr Alternating current is denoted as i sr And the DC voltage after AC is converted to DC is denoted as U. zr DC current is denoted as I zr The output voltage of the current output by the output unit is denoted as U. sc The output current is denoted as I. sc ;

[0056] For basic operating parameters: The rated voltage is denoted as U. ed The rated current is denoted as I. ed The output loss coefficient is denoted as Gp. ed .

[0057] like Figure 2 As shown: In another embodiment of the present invention, the process of the programmable module constructing the dynamic running model is specifically as follows:

[0058] Create corresponding component nodes for each component of the DC power module, and generate corresponding virtual connection lines for each component node according to the connection relationship between each component in the DC power module. Connect each component node through the virtual connection lines to obtain the initial simulation model of the DC power module.

[0059] The obtained operational data is imported into the corresponding component nodes. Within each component node, a corresponding visualization of data change is generated based on the imported operational data. In the specific implementation process, the component nodes are also equipped with link ports, which are associated with the corresponding visualization of data change. The visualization of data change can be brought up by clicking the link port.

[0060] Introduce the basic operating parameters of the DC power supply into the visualized data change chart, and generate the corresponding standard data range in the visualized data change chart based on the introduced basic operating parameters of the DC power supply.

[0061] For example: If the running data in the component node corresponding to the input unit is AC voltage and AC current, then a time coordinate system with respect to current and voltage is constructed, and corresponding AC voltage change curves and AC current change curves are generated based on AC voltage and AC current, as well as corresponding DC voltage change curves and DC current change curves are generated based on DC voltage and DC current.

[0062] By mapping each change curve to a coordinate system, a visual data change graph corresponding to the input unit is obtained;

[0063] Then, based on the rated current and rated voltage, corresponding current threshold lines and voltage threshold lines are generated in the coordinate system as the standard data range for this visualization data change graph;

[0064] The adjustment unit and output unit also import the corresponding operating data and basic operating parameters in a similar manner, except that there are slight differences in the specific data. Those skilled in the art can make corresponding adjustments, which will not be elaborated here.

[0065] Import the visualization data change graphs of each component node into the corresponding component node in the initial simulation model, and run the simulation on each component node to obtain the corresponding dynamic running model.

[0066] In another embodiment of the present invention, after the construction of the dynamic operation model of the DC power supply is completed, the operation status of the DC power supply is analyzed according to the constructed dynamic operation model, and the operation of the DC power supply is judged according to the analysis results to determine whether there is any abnormality in the operation of the DC power supply.

[0067] Example: For an input unit, the visualization data change graph of the corresponding component node of the input unit is marked, and a time window of fixed duration is set in the visualization data change graph. The duration of the time window is T, and the time window consists of the current moment and the previous moment with an interval of T from the current moment.

[0068] Current and voltage variation curves within the calibration time window;

[0069] It can be seen that the AC current change curve and AC voltage change curve in the visualization data change graph corresponding to the input unit are AC current and AC voltage, and the input unit needs to convert AC to DC.

[0070] The generated DC voltage change curve and DC current change curve are compared with the corresponding standard data range. If the DC voltage change curve and DC current change curve are within the corresponding standard data range, it indicates that the input unit is operating normally.

[0071] If any point in time or segment of the DC voltage change curve and DC current change curve within the time window exceeds the standard data range, it indicates that the input unit is operating abnormally. In this case, a corresponding input adjustment command is generated and sent to the adjustment compensation module.

[0072] For the output unit, the visualization data change graph of the corresponding component node of the output unit is marked;

[0073] The system acquires the demand information from the power consumption terminal through the output unit, and generates corresponding demand voltage change curves and demand current change curves in the visualized data change graph based on the demand information from the power consumption terminal.

[0074] Set the data evaluation period within the visualized data change chart;

[0075] The demand voltage change curve and demand current change curve within the data evaluation period are compared with the rated voltage and rated current, respectively. If the voltage corresponding to any point on the demand voltage change curve is higher than the rated voltage, or the voltage corresponding to the demand current change curve is higher than the rated voltage, or the current corresponding to the demand current change curve is higher than the rated current, it indicates that the DC power supply cannot meet the power demand of the user. The corresponding warning information is then generated and sent to the regulating unit. The regulating unit disconnects the output unit from the user based on the warning information.

[0076] If the voltages corresponding to the demand voltage change curves are all not higher than the rated voltage, and the currents corresponding to the demand current change curves are all not higher than the rated current, it means that the DC power supply can meet the power demand of the user. Then, the adjustment and compensation module evaluates the performance degradation of the DC power supply and performs power supply compensation to the user based on the performance degradation of the DC power supply.

[0077] In another embodiment of the present invention, the process by which the adjustment and compensation module evaluates the performance degradation of the DC power supply includes:

[0078] Based on the demand voltage change curve and the demand current change curve, the corresponding expected output voltage change curve Uy of the DC power supply is generated. sc (t) and the expected output current variation curve Iy sc (t); It should be noted that the expected output voltage change curve and the expected output current change curve are obtained based on the output loss coefficient of the DC power supply;

[0079] The output voltage is U based on the current output by the obtained output unit. sc Output current I sc Generate the corresponding actual output voltage change curves U respectively sc (t) and the actual output current variation curve I sc (t);

[0080] Then, at the end of each data evaluation period, the power supply attenuation coefficient of the DC power supply is obtained, denoted as Gs, where:

[0081]

[0082] Among them, T p For the duration of the data evaluation period;

[0083] Set the power supply attenuation coefficient threshold, denoted as G0;

[0084] When Gs < G0, it indicates that the DC power supply is functioning normally and no action is required.

[0085] When Gs≥G0, it indicates that the DC power supply performance is degraded, and a power supply compensation command is generated.

[0086] In another embodiment of the present invention, the adjustment and compensation module marks any time point or curve segment of the DC voltage change curve and DC current change curve within the time window that exceeds the standard data range according to the input adjustment command, and obtains the difference between the maximum current value and the maximum voltage value that exceeds the standard data range and the standard data range. Based on the obtained difference, the corresponding AC voltage and AC current are adjusted accordingly so that the converted DC voltage and DC current are within the standard data range, thereby protecting the DC power supply from damage.

[0087] In another embodiment of the present invention, the process of adjusting and compensating the DC power output by the DC power supply module when the DC power output does not match the demand at the power consumption end includes:

[0088] Based on the obtained power supply attenuation coefficient Gs of the DC power supply, at the beginning of the next data evaluation cycle, a corresponding correction coefficient is generated for the basic operating parameters of the DC power supply, with the correction coefficient being 1-Gs.

[0089] The basic operating parameters of the DC power supply are then updated based on the correction factor.

[0090] Example: For the rated voltage, the updated rated voltage is (1-Gs)U ed The updated rated current is (1-Gs)I ed The output loss coefficient is (1-Gs)G ped ;

[0091] Based on the updated output loss coefficient, new expected output voltage change curves and expected output current change curves are generated. Based on the average difference between the actual output voltage change curves and actual output current change curves within the current data evaluation period and the new expected output voltage change curves and expected output current change curves, the corresponding compensation voltage value and compensation current value are obtained. Based on the obtained compensation voltage value and compensation current value, power supply compensation is performed on the power consumption terminal of the DC power supply.
