Description

Technical Field

[0001] The present invention relates to the technical field of design control, and particularly to a modular design control method and system for a power distribution unit of an intelligent power distribution cabinet. Background Art

[0002] A power distribution cabinet is an important device for power distribution and protection in a power system, and is widely used in various power supply places such as industry, commerce and residence. Its main function is to convert high-voltage electrical energy into low-voltage electrical energy suitable for downstream equipment, and provide corresponding protection, control and monitoring functions; the power distribution unit in the power distribution cabinet includes key components such as transformers, circuit breakers, load control devices, measuring instruments, etc.; the design requirements of the power distribution unit can ensure the stable and safe operation of the power system under load fluctuations and environmental changes; in recent years, the modular design of the power distribution unit has received extensive attention. By independently encapsulating and controlling each functional module, the maintainability and flexibility of the equipment can be improved, and the overall efficiency of the power distribution system can be optimized.

[0003] There are still many deficiencies in the existing technology for the design of the power distribution unit of the power distribution cabinet; most of the existing power distribution cabinets adopt traditional static control methods, lacking a dynamic response mechanism for real-time changes in environmental factors such as temperature and humidity; the power distribution unit is greatly affected by temperature and humidity changes during operation. Too high or too low temperature and humidity will not only affect the working efficiency of components, but may also cause early failures of the equipment; moreover, the existing technology fails to effectively combine temperature and humidity data with power load regulation, resulting in the inability to make precise adjustments under real-time environmental changes; in addition, the existing power distribution cabinet control methods usually rely on preset temperature and humidity thresholds, lacking intelligent adjustment and early warning functions based on real-time data, and unable to adjust the operating state in a timely manner when the load fluctuates greatly, there is a risk of equipment overload or unstable operation. Summary of the Invention

[0004] The purpose of the present invention is to provide a modular design control method and system for a power distribution unit of an intelligent power distribution cabinet to solve the problems raised in the above background art.

[0005] To solve the above technical problems, the present invention provides the following technical solutions:

[0006] Modular Design Control Method for the Power Distribution Unit of an Intelligent Power Distribution Cabinet. This method includes the following steps: Set functional areas for the power distribution unit of the intelligent power distribution cabinet. The functional areas include an environmental perception functional area, an intelligent control functional area, and a power regulation functional area. The environmental perception functional area obtains temperature data and humidity data based on time series. Based on the temperature data and the humidity data, the intelligent control functional area controls the operation of the components in the intelligent power distribution cabinet to adjust the optimal temperature and humidity range. Calculate the power generated by the components during operation. Based on the power, calculate the comprehensive current data and comprehensive voltage data of the components. Based on the comprehensive current data and comprehensive voltage data, calculate the comprehensive power and operation impact degree of the components. Preset a threshold value, analyze and output a warning to the intelligent control functional area.

[0007] As a preferred solution of the modular design control method for the power distribution unit of the intelligent power distribution cabinet of the present invention, the operation mode of the environmental perception functional area is specifically as follows:

[0008] Divide the time within a day evenly into A time points, construct a time acquisition sequence, denoted as TI = {T a |a ∈ [1, A]}, where T a represents the a-th time point, and A represents the total number of time points. Respectively, record the temperature data and humidity data of the intelligent power distribution cabinet sensed by the environmental perception functional area at time point T a as WD(T a ) and SD(T a ).

[0009] As a preferred solution of the modular design control method for the power distribution unit of the intelligent power distribution cabinet of the present invention, the operation mode of the intelligent control functional area is specifically as follows:

[0010] The intelligent control functional area presets an optimal temperature range and an optimal humidity range. Respectively, compare the temperature data WD(T a ) and humidity data SD(T a ) sensed by the environmental perception functional area with the optimal temperature range and the optimal humidity range. According to the comparison results, control the intelligent power distribution cabinet to operate within the optimal temperature and humidity range, specifically as follows:

[0011] If the temperature data WD(T a ) is greater than the maximum temperature within the optimal temperature range, the intelligent control functional area operates the cooling element to lower the temperature.

[0012] If the temperature data WD(T a ) is less than the minimum temperature within the optimal temperature range, the intelligent control functional area operates the heating element to raise the temperature.

[0013] If the humidity data SD(Ta ) If it is greater than the maximum humidity within the optimal humidity range, the intelligent control function area operates the dehumidifying element to dehumidify.

[0014] If the humidity data SD(T a ) is less than the minimum humidity within the optimal humidity range, the intelligent control function area operates the atomizing element to humidify.

[0015] It should be noted that for the heating or cooling of temperature and the dehumidifying and humidifying of humidity, at each time point, only a single type of power adjustment will be performed. Because at a single time point, the temperature is either greater than the highest temperature within the optimal temperature range, less than the lowest temperature within the optimal temperature range, or between the lowest temperature and the highest temperature within the optimal temperature range. Therefore, either the power of the cooling element inside the function module is adjusted to cool down, or the power of the heating element inside the function module is adjusted to heat up. The adjustment method of humidity is the same as above. Therefore, at each time point, a total of four temperature and humidity power adjustment methods will be generated: 1. Adjust the power of the cooling element inside the function module to cool down and adjust the power of the dehumidifying element inside the function module to dehumidify; 2. Adjust the power of the cooling element inside the function module to cool down and adjust the power of the atomizing element inside the function module to humidify; 3. Adjust the power of the heating element inside the function module to heat up and adjust the power of the dehumidifying element inside the function module to dehumidify; 4.

[0027] Among them, D dehumid represents the power generated by the dehumidifying element during operation, and k dehumid represents the preset coefficient of change of the power of the dehumidifying element with humidity.

[0028] Calculate the power generated by the atomizing element during operation, and the calculation formula is as follows:

[0029] D humid =k humid ×(SD min -SD(T a ));

[0030] Among them, D humid represents the power generated by the atomizing element during operation, and khumid Represents the change ratio coefficient of the power of the preset atomization element to the humidity.

[0031] As a preferred solution of the modular design control method of the power distribution unit of the intelligent power distribution cabinet described in the present invention, at time point T a The power generated by the element for adjusting the temperature during operation and the power generated by the element for adjusting the humidity during operation are respectively denoted as S i and D j , where S i ∈[S fan , S heat , D j ∈[D dehumid , D humid .

[0032] Calculate the comprehensive current data and comprehensive voltage data of the element for adjusting the temperature and the element for adjusting the humidity at time point T a , and the formulas are as follows:

[0033] I(T a ) = β 1 ×(S i + D j ) + β 2 ×|S i - D j |;

[0034] V(T a ) = μ 1 ×(S i + D j ) + μ 2 ×|S i - D j |;

[0035] Among them, I(T a ) represents the comprehensive current data of the element for adjusting the temperature and the element for adjusting the humidity at time point T a , β 1 represents the comprehensive power-to-current conversion coefficient of the preset power S i and the power D j , β 2 represents the power-to-current conversion coefficient of the difference between the preset power S i and the power D j , V(T a ) represents the comprehensive voltage data of the element for adjusting the temperature and the element for adjusting the humidity at time point T a .

[0036] As a preferred solution of the modular design control method of the power distribution unit of the intelligent power distribution cabinet described in the present invention, the specific process of the dynamic control is as follows:

[0037] Based on the time point T a the combined current data I(T a ) and combined voltage data V(T a ) of the component for adjusting temperature and the component for adjusting humidity at the time point T a calculate the combined power of the component for adjusting temperature and the component for adjusting humidity at the time point T

[0038] CP(T a ) = I(T a ) × V(T a );

[0039] wherein, CP(T a ) represents the combined power of the component for adjusting temperature and the component for adjusting humidity at the time point T a .

[0040] Based on the combined power CP(T a ), calculate the influence degree of the component for adjusting temperature and the component for adjusting humidity on the operation of the function module at the time point T a , and the calculation formula is as follows:

[0042] wherein, OID(T a ) represents the influence degree of the component for adjusting temperature and the component for adjusting humidity on the operation of the function module at the time point T a , and P(T a ) represents the reference power value at the a-th preset time point T a .

[0043] Preset an operation influence degree threshold τ. If the operation influence degree OID(T a ) > τ, it is determined that the component for adjusting temperature and the component for adjusting humidity have a great influence on the operation of the function module, and a warning is sent to the intelligent control function area to stop the operation of the component.

[0044] If the operation influence degree OID(T a ) < τ, it is determined that the component for adjusting temperature and the component for adjusting humidity have a small influence on the operation of the function module, and no warning is sent to the intelligent control function area, and the operation of the component continues.

[0045] Let a = a + 1, return to the intelligent control function area, perform iteration of time points, and perform dynamic control management according to the intelligent control function area and the power adjustment function area.

[0066] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0067] Please refer to Figure 1 , in the first embodiment: A control method for the modular design of the power distribution unit of an intelligent power distribution cabinet is provided, and the method includes the following steps:

[0068] Step S1: Set functional areas for the power distribution unit of the intelligent power distribution cabinet, and the functional areas include an environmental perception functional area, an intelligent control functional area, and a power regulation functional area; the environmental perception functional area obtains temperature data and humidity data based on a time series.

[0069] Specifically, the operation mode of the environmental perception functional area is as follows:

[0070] Divide the time within a day evenly into A time points, construct a time acquisition sequence, denoted as TI = {T a |a ∈ [1, A]}, where T a represents the a-th time point, and A represents the total number of time points; respectively denote the temperature data and humidity data of the intelligent power distribution cabinet sensed by the environmental perception functional area at the time point T a as WD(T a ) and SD(T a ).

[0071] Step S2: Based on the temperature data and the humidity data, the intelligent control functional area controls the operation of the components in the intelligent power distribution cabinet to adjust the optimal temperature and humidity range.

[0072] Specifically, the operation mode of the intelligent control functional area is as follows:

[0073] The intelligent control functional area presets an optimal temperature range and an optimal humidity range, and respectively takes the temperature data WD(T a ) and humidity data SD(T a)Compare with the optimal temperature range and the optimal humidity range, and control the intelligent power distribution cabinet to operate within the optimal temperature and humidity range according to the comparison results, as follows:

[0074] If the temperature data WD(T a ) is greater than the maximum temperature within the optimal temperature range, the intelligent control function area operates the cooling element to cool down.

[0075] If the temperature data WD(T a ) is less than the minimum temperature within the optimal temperature range, the intelligent control function area operates the heating element to heat up.

[0076] If the humidity data SD(T a ) is greater than the maximum humidity within the optimal humidity range, the intelligent control function area operates the dehumidifying element to dehumidify.

[0077] If the humidity data SD(T a ) is less than the minimum humidity within the optimal humidity range, the intelligent control function area operates the atomizing element to humidify.

[0078] It should be noted that for the heating or cooling of temperature and the dehumidifying and humidifying of humidity, at each time point, only a single type of power adjustment will be performed. Because at a single time point, the temperature is either greater than the highest temperature within the optimal temperature range, less than the lowest temperature within the optimal temperature range, or between the lowest temperature and the highest temperature within the optimal temperature range. Therefore, either the power of the cooling element inside the function module is adjusted to cool down, or the power of the heating element inside the function module is adjusted to heat up. The adjustment method for humidity is the same as above. Therefore, at each time point, a total of four temperature and humidity power adjustment methods will be generated: 1. Adjust the power of the cooling element inside the function module to cool down and adjust the power of the dehumidifying element inside the function module to dehumidify; 2. Adjust the power of the cooling element inside the function module to cool down and adjust the power of the atomizing element inside the function module to humidify; 3. Adjust the power of the heating element inside the function module to heat up and adjust the power of the dehumidifying element inside the function module to dehumidify; 4. Adjust the power of the heating element inside the function module to heat up and adjust the power of the atomizing element inside the function module to humidify.

[0079] Step S3: Calculate the power generated when the component is operating; based on the power, calculate the comprehensive current data and comprehensive voltage data of the component.

[0080] Specifically, the operation mode of the power adjustment function area is as follows:

[0081] Based on step S2, obtain the components operating in the intelligent control function area and calculate the power generated by the components during operation, specifically as follows:

[0082] Denote the optimal temperature range and the optimal humidity range as [WD min , WD max and [SD min , SD max , respectively, where WD min represents the lowest temperature within the optimal temperature range, and WD max represents the highest temperature within the optimal temperature range, and SD min represents the lowest humidity within the optimal humidity range, and SD max represents the highest humidity within the optimal humidity range.

[0083] Calculate the power generated by the cooling element during operation. The calculation formula is as follows:

[0084] S fan = S now + k fan × (WD(T a ) - WD max );

[0085] Where S fan represents the power generated by the cooling element during operation, S now represents the basic power of the cooling element, and k fan represents the preset proportionality coefficient of the power of the cooling element to the temperature change.

[0086] For example, assume that the basic power S now of the cooling element is 5, the proportionality coefficient is 0.7, WD(T a ) is 27, and WD max is 25. Substituting these values into the formula, the power S fan generated by the cooling element during operation is calculated as 5 + 0.7 × 2 = 6.4.

[0087] Calculate the power generated by the heating element during operation. The calculation formula is as follows:

[0088] S heat = P now + k heat × (WD min - WD(T a ));

[0089] Where S heat represents the power generated by the heating element during operation, P now represents the basic power of the heating element, and k heatRepresents the proportionality coefficient of the power of the preset heating element to the temperature change.

[0090] For example, assume the base power P of the heating element now is 4, the proportionality coefficient k heat is 0.85, WD min is 21, WD(T a ) is 18. Substitute into the formula to calculate the power S generated by the heating element during operation heat = 4 + 0.85×3 = 6.55.

[0091] Calculate the power generated by the dehumidifying element during operation. The calculation formula is as follows:

[0092] D dehumid = k dehumid ×(SD(T a ) - SD max );

[0093] Among them, D dehumid represents the power generated by the dehumidifying element during operation, and k dehumid represents the proportionality coefficient of the power of the preset dehumidifying element to the humidity change.

[0094] For example, assume the proportionality coefficient k dehumid is 0.75, SD(T a ) is 28, SD max is 25. Substitute into the formula to calculate the power D generated by the dehumidifying element during operation dehumid = 0.75×3 = 2.25.

[0095] Calculate the power generated by the atomizing element during operation. The calculation formula is as follows:

[0096] D humid = k humid ×(SD min - SD(T a ));

[0097] Among them, D humid represents the power generated by the atomizing element during operation, and k humid represents the proportionality coefficient of the power of the preset atomizing element to the humidity change.

[0098] For example, assume the proportionality coefficient k humid is 0.95, SD(T a ) is 17, SD min is 22. Substitute into the formula to calculate the power D generated by the atomizing element during operation humid = 0.95×5 = 4.75.

[0099] Further, at time point T a when the power generated by the component for adjusting temperature during operation and the power generated by the component for adjusting humidity during operation are respectively denoted as S i and D j , where S i ∈[S fan , S heat , D j ∈[D dehumid , D humid .

[0100] Calculate the comprehensive current data and comprehensive voltage data of the component for adjusting temperature and the component for adjusting humidity at time point T a as follows:

[0101] I(T a ) = β 1 ×(S i + D j ) + β 2 ×|S i - D j |;

[0102] V(T a ) = μ 1 ×(S i + D j ) + μ 2 ×|S i - D j |;

[0103] where I(T a ) represents the comprehensive current data of the component for adjusting temperature and the component for adjusting humidity at time point T a , β 1 represents the conversion coefficient from the comprehensive power of the preset power S i and the power D j to current, β 2 represents the conversion coefficient from the power difference between the preset power S i and the power D j to current, V(T a ) represents the comprehensive voltage data of the component for adjusting temperature and the component for adjusting humidity at time point T a .

[0104] For example, assume that β 1 is 0.1, β 2 is 0.2, μ 1 is 0.6, μ 2 is 0.65, S i = S fan = 5 + 0.7×2 = 6.4, D j = Ddehumid = 0.75 × 3 = 2.25, substituting into the formula to calculate the comprehensive current data I(T a ) = 0.1 × 8.65 + 0.2 × 4.15 = 0.865 + 0.83 = 1.7; the comprehensive voltage data V(T a ) = 0.6 × 8.65 + 0.65 × 4.15 = 5.19 + 2.7 = 7.89.

[0105] Step S4: Based on the comprehensive current data and the comprehensive voltage data, calculate the comprehensive power and the operation influence degree of the component; preset a threshold, analyze and output a warning to the intelligent control function area.

[0106] Specifically, the specific process of the dynamic control is as follows:

[0107] Based on the time point T a the comprehensive current data I(T a ) and the comprehensive voltage data V(T a ) of the component for adjusting temperature and the component for adjusting humidity at the time, calculate the comprehensive power of the component for adjusting temperature and the component for adjusting humidity at the time point T a . The calculation formula is as follows:

[0108] CP(T a ) = I(T a ) × V(T a );

[0109] where CP(T a ) represents the comprehensive power of the component for adjusting temperature and the component for adjusting humidity at the time point T a .

[0110] For example, given I(T a ) = 0.1 × 8.65 + 0.2 × 4.15 = 0.865 + 0.83 = 1.7, V(T a ) = 0.6 × 8.65 + 0.65 × 4.15 = 5.19 + 2.7 = 7.89, CP(T a ) = 1.7 × 7.89 = 13.413.

[0111] Furthermore, based on the comprehensive power CP(T a ), calculate the operation influence degree of the component for adjusting temperature and the component for adjusting humidity on the function module at the time point T a . The calculation formula is as follows:

[0112]

[0113] where OID(T a ) represents at the time point T aAdjust the influence degrees of the temperature - adjusting element and the humidity - adjusting element on the operation of the function module. P(T a ) represents the reference power value at the preset a - th time point T a .

[0114] For example, assume that the comprehensive power CP(T a ) is 30. Substituting it into the formula, the operation influence degree is obtained

[0115] Furthermore, preset an operation influence degree threshold τ. If the operation influence degree OID(T a ) > τ, it is determined that the temperature - adjusting element and the humidity - adjusting element have a great influence on the operation of the function module. Then, a warning is sent to the intelligent control function area, and the operation of the elements is stopped.

[0116] If the operation influence degree OID(T a ) < τ, it is determined that the temperature - adjusting element and the humidity - adjusting element have a small influence on the operation of the function module. Then, no warning is sent to the intelligent control function area, and the operation of the elements continues.

[0117] For example, assume that the operation influence degree threshold τ is 0.4. Then, the operation influence degree OID(T a ) = 0.45 > τ = 0.4. It is determined that the temperature - adjusting element and the humidity - adjusting element have a great influence on the operation of the function module. Then, a warning is sent to the intelligent control function area, and the operation of the elements is stopped.

[0118] Let a = a + 1, return to step S2, perform time - point iteration, and perform dynamic control management according to the intelligent control function area and the power - regulation function area.

[0119] Please refer to Figure 2 . In the second embodiment: Provide a modular design control system for the power distribution unit of an intelligent power distribution cabinet. The system includes: an environment perception function module, a data management center, an intelligent control function module, and a power - regulation function module.

[0120] The output end of the environment perception function module is connected to the input end of the data management center. The output end of the data management center is connected to the input end of the intelligent control function module. The output end of the intelligent control function module is connected to the input end of the power - regulation function module.

[0121] The environment perception function module includes a temperature - humidity acquisition unit, which acquires the temperature data and humidity data of the intelligent power distribution cabinet through the temperature - humidity acquisition unit.

[0122] The acquired temperature data and humidity data are stored and managed through the data management center.

[0123] Control the operation of the components in the intelligent power distribution cabinet through the intelligent control function module, so that the intelligent power distribution cabinet operates within the optimal temperature and humidity range.

[0124] Obtain the operating power of the components in the intelligent control functional area through the power adjustment function module, perform dynamic control, and issue a warning to the intelligent control functional area.

[0125] The intelligent control function module further includes an optimal temperature and humidity adjustment unit:
