[0002] The distribution cabinet is an important equipment for power distribution and protection in the power system. It is widely used in various power supply places such as industry, commerce and residence. Its main function is to convert high-voltage electric energy into low-voltage electric energy suitable for downstream equipment, and provide corresponding protection, control and monitoring functions; the distribution unit in the distribution cabinet contains key components such as transformers, circuit breakers, load control equipment, measuring instruments, etc.; the design requirements of the 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 distribution unit has received widespread attention. By independently packaging and controlling each functional module, the maintainability and flexibility of the equipment can be improved, and the overall efficiency of the distribution system can be optimized.

[0003] The existing technology still has many shortcomings in the design of distribution units of distribution cabinets; most of the existing distribution cabinets adopt traditional static control methods, and lack a dynamic response mechanism to real-time changes in environmental factors such as temperature and humidity; the distribution unit is greatly affected by changes in temperature and humidity during operation. Too high or too low temperature and humidity will not only affect the working efficiency of the components, but may also cause early failure of the equipment; and 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 distribution cabinet control method usually relies on preset temperature and humidity thresholds, and lacks intelligent adjustment and early warning functions based on real-time data. It is impossible to adjust the operating status in time when the load fluctuates greatly, and 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-mentioned background technology.

[0032] Calculate at time point T a The comprehensive current data and comprehensive voltage data of the temperature adjustment component and the humidity adjustment component 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 |;

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0067] See also Figure 1 In the first embodiment of the present invention, a method for modular design and control of a power distribution unit of an intelligent power distribution cabinet is provided, and the method comprises the following steps:

[0068] Step S1: setting functional areas for the power distribution unit of the intelligent power distribution cabinet, wherein 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 acquires temperature data and humidity data based on a time series.

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

[0070] The time in a day is evenly divided into A time points, and a time acquisition sequence is constructed, denoted as TI = {T a |a∈[1,A]}, where T a represents the ath time point, A represents the total number of time points; respectively, time point T a The temperature data and humidity data of the intelligent power distribution cabinet sensed by the environment sensing functional area are recorded as WD (T a ) and SD(T a ).

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

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

[0073] The intelligent control function area is preset with an optimal temperature range and an optimal humidity range, and the temperature data WD(T a ) and humidity data SD(T a ) is compared with the optimal temperature range and the optimal humidity range, and according to the comparison result, the intelligent power distribution cabinet is controlled to operate within the optimal temperature and humidity range, 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 increase the temperature.

[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 dehumidification 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 for the dehumidification and humidification of humidity, at each time point, only a single power adjustment will be performed, because at a single time point, the temperature is either greater than the highest temperature in the optimal temperature range, or less than the lowest temperature in the optimal temperature range, or between the lowest temperature in the optimal temperature range and the highest temperature in the optimal temperature range, so either the power of the cooling element inside the functional module is adjusted to cool down, or the power of the heating element inside the functional module is adjusted to heat up, and the humidity is adjusted in the same way 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 functional module to cool down, and adjust the power of the dehumidification element inside the functional module to dehumidify; 2. Adjust the power of the cooling element inside the functional module to cool down, and adjust the power of the atomization element inside the functional module to humidify; 3. Adjust the power of the heating element inside the functional module to heat up, and adjust the power of the dehumidification element inside the functional module to dehumidify; 4. Adjust the power of the heating element inside the functional module to heat up, and adjust the power of the atomization element inside the functional module to humidify.

[0079] Step S3: Calculate the power generated by the component during operation; and calculate the comprehensive current data and the comprehensive voltage data of the component based on the power.

[0080] Specifically, the operation mode of the power regulation functional area is as follows:

[0081] Based on step S2, the elements of the intelligent control functional area are obtained, and the power generated by the elements during operation is calculated, as follows:

[0082] The optimal temperature range and the optimal humidity range are respectively recorded as [WD min ,WD max and [SD min ,SD max ], where WDmin Indicates the lowest temperature within the optimal temperature range, WD max Indicates the highest temperature within the optimal temperature range, SD min Indicates the lowest humidity within the optimal humidity range, SD max Indicates the highest humidity within the optimal humidity range.

[0083] The power generated by the cooling element during operation is calculated using the following formula:

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

[0085] Among them, S fan represents the power generated by the cooling element when in operation, S now represents the base power of the cooling element, k fan Indicates the proportional coefficient of the power and temperature change of the preset cooling element.

[0086] For example, assuming that the base power S of the cooling element now is 5, the change ratio coefficient is 0.7, WD(T a ) is 27, WD max =25, and the power S generated by the cooling element during operation is calculated by substituting it into the formula fan =5+0.7×2=6.4.

[0087] The power generated by the heating element when in operation is calculated using the following formula:

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

[0089] Among them, S heat represents the power generated by the heating element when in operation, P now represents the base power of the heating element, k heat Indicates the preset proportional coefficient of the heating element's power and temperature.

[0090] For example, assuming that the base power P of the heating element now is 4, the change ratio k heat 0.85, WD min is 21, WD(T a ) is 18, and the power S generated by the heating element during operation is calculated by substituting it into the formulaheat =4+0.85×3=6.55.

[0091] The power generated by the dehumidification element during operation is calculated using the following formula:

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

[0093] Among them, D dehumid represents the power generated by the dehumidification element during operation, k dehumid Indicates the proportional coefficient of the power and humidity of the preset dehumidification element.

[0094] For example, assuming the change proportionality factor k dehumid is 0.75, SD(T a ) is 28, SD max =25, and the power D generated by the dehumidification element during operation is calculated by substituting it into the formula dehumid =0.75×3=2.25.

[0095] The power generated by the atomizing element during operation is calculated using the following formula:

[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, k humid Indicates the preset proportional coefficient of the power and humidity of the atomizing element.

[0098] For example, assuming the change proportionality factor k humid is 0.95, SD(T a ) is 17, SD min =22, and the power D generated by the atomizing element during operation is calculated by substituting it into the formula humid =0.95×5=4.75.

[0099] Furthermore, at time point T a When the temperature adjustment element is in operation, the power generated by the temperature adjustment element and the power generated by the humidity adjustment element are respectively recorded as S i and D j , where S i ∈[S fan ,S heat ], D j ∈[D dehumid,D humid ].

[0100] Calculate at time point T a The comprehensive current data and comprehensive voltage data of the temperature adjustment component and the humidity adjustment component are 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] Among them, I(T a ) indicates that at time point T a The comprehensive current data of the temperature adjustment element and the humidity adjustment element, β 1 Indicates the preset power S i and power D j The comprehensive power-to-current conversion factor, β 2 Indicates the preset power S i and power D j The power to current conversion factor of the difference, V(T a ) represents the time point T a The comprehensive voltage data of the components that adjust the temperature and the components that adjust the humidity.

[0104] For example, assuming 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 =D dehumid =0.75×3=2.25, substitute it 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;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, the comprehensive power and operation impact of the component are calculated; a threshold is preset, and an analysis is performed and an early warning is output to the intelligent control functional area.

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

[0107] Based on time point T a The comprehensive current data of the temperature adjustment element and the humidity adjustment element I(T a ) and comprehensive voltage data V(T a ), calculate the time point T a The combined power of the temperature adjustment component and the humidity adjustment component is calculated as follows:

[0108] CP(T a )=I(T a )×V(T a );

[0109] Among them, CP(T a ) represents the time point T a The combined power of the components that adjust the temperature and the components that adjust the humidity.

[0110] For example, it is known that 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 ), calculated at time point T a The influence of the temperature adjustment element and the humidity adjustment element on the operation of the functional module is calculated as follows:

[0112]

[0113] Among them, OID(T a ) indicates that at time point T a The influence of the temperature adjusting element and the humidity adjusting element on the operation of the functional module.

[0114] For example, assuming that the total power CP(T a ) is 30, and the running impact is obtained by substituting it into the formula

[0115] Furthermore, a preset operation impact threshold τ is set. If the operation impact 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 functional module, and an early warning is issued to the intelligent control functional area to stop the operation of the elements.

[0116] If the operation impact OID (T a )<τ, it is determined that the temperature adjusting element and the humidity adjusting element have little influence on the operation of the functional module, and no warning is issued to the intelligent control functional area, and the operation of the elements continues.

[0117] For example, assuming that the operation impact threshold τ is 0.4, the operation impact 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 functional module, and an early warning is issued to the intelligent control functional area to stop the operation of the elements.

[0118] Let a=a+1, return to step S2, iterate the time points, and perform dynamic control management according to the intelligent control functional area and the power regulation functional area.
