Description

Technical Field

[0001] The invention relates to the technical field of direct current power supplies, in particular to a programmable direct current power supply process operating parameter adjustment and compensation system. Background Art

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

[0003] During actual operation, programmable DC power supplies are subject to interference from a variety of factors. Ambient temperature fluctuations can cause parameter drift in the power supply's internal electronic components, affecting the stability of the output voltage and current. Grid voltage fluctuations can also directly affect the power supply input, causing output parameters to deviate from preset values. Furthermore, dynamic load changes, such as sudden connection or disconnection of loads and frequent changes in load size, can cause power supply output instability, resulting in voltage drops or overshoots.

[0004] How to make appropriate adjustments and compensation for the DC power supply according to the real-time operating data of the DC power supply input and output during operation, so as to make the operation of the DC power supply safer and more efficient, is a problem we need to solve. To this end, we now provide a programmable DC power supply process operation parameter adjustment and compensation system. Summary of the Invention

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

[0006] The object of the present invention can be achieved by the following technical solution: a programmable DC power supply process operation parameter adjustment and compensation system, comprising:

[0007] The DC power supply module includes an input unit, an output unit, and a regulating unit. The input unit converts external AC power into corresponding DC power, and then connects to the power consumption end through the output unit to transmit the DC power to the power consumption end. During the process of the output unit outputting the DC power to the power consumption end, the regulating unit dynamically adjusts the output DC power and performs parameter compensation.

[0008] A programmable module for presetting basic operating parameters of the DC power supply, including rated current, rated voltage, and output loss factor, and for constructing a dynamic operating model based on operating data of the DC power supply module;

[0009] A data acquisition module, configured to obtain operating data of the DC power supply module, wherein the operating data includes the alternating current 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 to determine whether the operation of the DC power supply is abnormal and whether the output DC power is compatible with the needs of the power 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 the operation of the DC power supply, and to compensate the DC power output by the DC power supply when the DC power output by the DC power supply does not match the demand of the power consumption end.

[0012] Furthermore, the process of constructing a dynamic operation model by the programmable module is as follows:

[0013] Create corresponding component nodes for each component of the DC power supply module, and generate corresponding virtual connection lines for each component node based on the connection relationship between the various components in the DC power supply module. Use the virtual connection lines to link the component nodes to obtain the initial simulation model of the DC power supply module;

[0014] Import the acquired operating data into the corresponding component nodes, and generate corresponding visual data change graphs in each component node according to the imported operating data;

[0015] Introducing basic operating parameters of the DC power supply into the visual data change graph, and generating corresponding standard data ranges in the visual data change graph according to the introduced basic operating parameters of the DC power supply;

[0016] The visualized data change diagram of each component node is imported into the corresponding component node in the initial simulation model, and each component node is simulated 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 operating data is constructed according to the operating data in the corresponding component node, and a corresponding change curve is generated according to the operating data;

[0018] Map each change curve into the coordinate system to obtain a visual data change diagram corresponding to each component node.

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

[0020] Calibrate the current change curve and voltage change curve within the time window;

[0021] The visual data change graph corresponding to the input unit includes the AC current change curve and the AC voltage change curve;

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

[0023] If any time point or curve segment of the DC voltage change curve and the DC current change curve within the time window exceeds the standard data range, it means that the input unit is operating abnormally, and a corresponding input adjustment instruction is generated and sent to the adjustment compensation module.

[0024] Furthermore, for the output unit, the visual data change graph of the component node corresponding to the output unit is marked;

[0025] Obtaining demand information of the power consumption end through the output unit, and generating corresponding demand voltage change curve and demand current change curve in the visual data change graph according to the demand information of the power consumption end;

[0026] Set the data evaluation cycle in the visual data change graph;

[0027] Compare the demand voltage change curve and the demand current change curve within the data evaluation period with the rated voltage and rated current respectively. If the voltage corresponding to any point of the demand voltage change curve is higher than the rated voltage, or if the voltage corresponding to the demand current change curve is higher than the rated voltage, or if the current corresponding to the demand current change curve is higher than the rated current, it means that the DC power supply cannot meet the power demand of the power consumption end, and then generate corresponding warning information, and send the warning information to the adjustment unit. The adjustment unit disconnects the output unit from the power consumption end according to the warning information;

[0028] If the voltages corresponding to the demand voltage change curves are not higher than the rated voltage, and the currents corresponding to the demand current change curves are not higher than the rated current, it means that the DC power supply can meet the power demand of the power consumption end. The adjustment and compensation module then evaluates the performance degradation of the DC power supply and compensates the power consumption end according to the performance degradation of the DC power supply.

[0029] Furthermore, the process of evaluating the performance degradation of the DC power supply by the regulating and compensating module includes:

[0030] Generate a corresponding estimated output voltage change curve and estimated output current change curve of the DC power supply according to the required voltage change curve and the required current change curve;

[0031] Generate corresponding actual output voltage change curve and actual output current change curve respectively according to the obtained output voltage and output current of the current output by the output unit;

[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 means that the DC power supply performance is normal and no treatment is required;

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

[0036] Furthermore, the adjustment and compensation module marks any time point or curve segment of the DC voltage change curve and the DC current change curve within the time window that exceeds the standard data range according to the input adjustment instruction, 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. According to 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 by the DC power supply does not match the demand of the power consumption end, the adjustment and compensation module performs power supply compensation on the DC power output by the DC power supply, including:

[0038] According to the obtained power supply attenuation coefficient 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.

[0039] Then, the basic operating parameters of the DC power supply are updated according to the correction coefficient to obtain an updated output loss coefficient;

[0040] Based on the updated output loss coefficient, a new expected output voltage change curve and an expected output current change curve are generated. According to the average of the differences between the actual output voltage change curve and the actual output current change curve in the current data evaluation period and the new expected output voltage change curve and the expected output current change curve, the corresponding compensation voltage value and compensation current value are obtained. According to the obtained compensation voltage value and compensation current value, power supply compensation is performed on the power consumption end of the DC power supply.

[0041] Compared with the prior art, the present invention has the following beneficial effects:

[0042] By combining the input and output operating data of the DC power supply with the basic operating parameters of the DC power supply, a corresponding dynamic operating model is constructed for the DC power supply, thereby dynamically simulating the operation of the DC power supply. According to the simulation results, the deviation between the actual operating data and the theoretical operating data of the DC power supply input and output is analyzed, and then the basic operating parameters of the DC power supply are corrected, thereby avoiding the probability of the DC power supply being in an abnormal operating state and improving the operating safety of the DC power supply. At the same time, according to the difference between the output of the DC power supply and the power supply required by the power consumption end, corresponding adaptive power supply compensation is performed on the power consumption end, thereby improving the operating efficiency of the DC power supply.

Obviously, the drawings described below are only some embodiments described in the present invention. For ordinary technicians in this field, other drawings can also be obtained based on these drawings.

[0045] Figure 2 It is a schematic diagram of the dynamic operation model of the present invention. DETAILED DESCRIPTION

[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. The overall concept adopted is as follows:

[0047] The operating data of the DC power supply module is obtained, and a dynamic operating model is constructed in combination with 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 operation of the DC power supply is abnormal and whether the output DC power is compatible with the needs of the power user. When there is an abnormality in the operation of the DC power supply, the operating data of the DC power supply is adjusted so that the abnormality of the DC power supply does not affect the power user. When the DC power output by the DC power supply does not match the needs of the power user, the DC power output by the DC power supply is compensated for.

[0048] like Figure 1 As shown, the programmable DC power 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. During the specific implementation process, the input unit converts the external input AC power into the corresponding DC power, and then connects to the power consumption end through the output unit to transmit the DC power to the power consumption end. In the process of the output unit outputting the DC power to the power consumption end, the adjustment unit dynamically adjusts the output DC power and compensates the parameters.

[0050] The programmable module is used to preset 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 a dynamic operation model based on the operation data of the DC power module;

[0052] The data acquisition module is composed of several data acquisition terminals and is used to obtain 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 to determine whether the operation of the DC power supply is abnormal and whether the output DC power is compatible with the needs of the power 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 the operation of the DC power supply so that the abnormality of the DC power supply will not affect the power consumption end, and to compensate for the DC power output by the DC power supply when the DC power output by the DC power supply does not match the demand of 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 inputted from the input unit is marked as U sr , the alternating current is recorded as i sr And the DC voltage after the AC is converted to DC is recorded as U zr , the DC current is recorded as I zr ; The output voltage of the current output by the output unit is recorded as U sc , the output current is recorded as I sc ;

[0056] For basic operating parameters: record the rated voltage as U ed , the rated current is recorded as I ed , the output loss coefficient is recorded as Gp ed .

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

[0058] Create corresponding component nodes for each component of the DC power supply module, and generate corresponding virtual connection lines for each component node based on the connection relationship between the various components in the DC power supply module. Use the virtual connection lines to link the component nodes to obtain the initial simulation model of the DC power supply module;

[0059] Import the obtained operating data into the corresponding component node, and generate a corresponding visual data change graph in each component node based on the imported operating data. In the specific implementation process, the component node is also provided with a link port, which is associated with the corresponding visual data change graph. The visual data change graph can be called up by clicking the link port;

[0060] Introducing basic operating parameters of the DC power supply into the visual data change graph, and generating corresponding standard data ranges in the visual data change graph according to the introduced basic operating parameters of the DC power supply;

[0061] For example, if the operating data in the component node corresponding to the input unit is AC voltage and AC current, 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 according to the AC voltage and AC current, and corresponding DC voltage change curves and DC current change curves are generated according to the DC voltage and DC current;

[0062] Map each change curve into the coordinate system to obtain a visual data change graph corresponding to the input unit;

[0063] Then, according to the rated current and rated voltage, the corresponding current threshold line and voltage threshold line are generated in the coordinate system as the standard data range of the visual data change graph;

[0064] The adjustment unit and the 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] The visualized data change diagram of each component node is imported into the corresponding component node in the initial simulation model, and each component node is simulated to obtain the corresponding dynamic operation model.

[0066] In another embodiment of the present invention, after the dynamic operation model of the DC power supply is constructed, the operation state of the DC power supply is analyzed according to the constructed dynamic operation model, and it is determined whether the operation of the DC power supply is abnormal based on the analysis result;

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

[0068] Calibrate the current change curve and voltage change curve within the time window;

[0069] It can be seen that the AC current change curve and the AC voltage change curve in the visual data change diagram corresponding to the input unit are AC current and AC voltage, and the input unit needs to convert AC power into DC power;

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

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

[0072] For an output unit, marking a visual data change graph of a component node corresponding to the output unit;

[0073] Obtaining demand information of the power consumption end through the output unit, and generating corresponding demand voltage change curve and demand current change curve in the visual data change graph according to the demand information of the power consumption end;

[0074] Set the data evaluation cycle in the visual data change graph;

[0075] Compare the demand voltage change curve and the demand current change curve within the data evaluation period with the rated voltage and rated current respectively. If the voltage corresponding to any point of the demand voltage change curve is higher than the rated voltage, or if the voltage corresponding to the demand current change curve is higher than the rated voltage, or if the current corresponding to the demand current change curve is higher than the rated current, it means that the DC power supply cannot meet the power demand of the power consumption end, and then generate corresponding warning information, and send the warning information to the adjustment unit. The adjustment unit disconnects the output unit from the power consumption end according to the warning information;

[0076] If the voltages corresponding to the demand voltage change curves are not higher than the rated voltage, and the currents corresponding to the demand current change curves are not higher than the rated current, it means that the DC power supply can meet the power demand of the power consumption end. The adjustment and compensation module then evaluates the performance degradation of the DC power supply and compensates the power consumption end according to the performance degradation of the DC power supply.

[0077] In another embodiment of the present invention, the process of the regulating and compensating module evaluating the performance degradation of the DC power supply includes:

[0078] According to the required voltage change curve and the required current change curve, the corresponding DC power supply output voltage change curve Uy is generated sc (t) and expected output current change 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 of the output unit is U according to the current outputted by the output unit. sc , output current I sc Generate the corresponding actual output voltage change curve U sc (t) and actual output current change curve I sc (t);

[0080] At the end of each data evaluation cycle, the power supply attenuation coefficient of the DC power supply is obtained, recorded as Gs, where:

[0081]

[0082] Among them, T p The duration of the data evaluation cycle;

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

[0084] When Gs<G0, it means that the DC power supply performance is normal and no treatment is required;

[0085] When Gs≥G0, it indicates that the DC power supply performance is attenuated, and a power supply compensation instruction 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 the DC current change curve within the time window that exceeds the standard data range according to the input adjustment instruction, and obtains the maximum current value and the difference between the maximum voltage value and the standard data range that exceed 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, when the DC power output by the DC power supply does not match the demand of the power consumption end, the process of the adjustment and compensation module performing power supply compensation on the DC power output by the DC power supply 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, and the correction coefficient is 1-Gs;

[0089] Then the basic operating parameters of the DC power supply are updated according to the correction coefficient;

[0090] For example: For 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, a new expected output voltage change curve and an expected output current change curve are generated. According to the average of the differences between the actual output voltage change curve and the actual output current change curve in the current data evaluation period and the new expected output voltage change curve and the expected output current change curve, the corresponding compensation voltage value and compensation current value are obtained. According to the obtained compensation voltage value and compensation current value, power supply compensation is performed on the power consumption end of the DC power supply.

Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention.
