[0090] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0091] The embodiments of the present application provide a method for configuring power supply for a distribution box based on grid integration. The execution subject of the method for configuring power supply for a distribution box based on grid integration includes, but is not limited to, at least one of electronic devices such as a server and a terminal that can be configured to execute the method provided in the embodiments of the present application. In other words, the method for configuring power supply for a distribution box based on grid integration can be executed by software or hardware installed on a terminal device or a server device, and the software can be a blockchain platform. The server includes, but is not limited to, a single server, a server cluster, a cloud server, or a cloud server cluster.

[0092] Reference Figure 1 FIG2 is a flow chart of a method for configuring a power distribution box based on grid integration according to an embodiment of the present invention. In this embodiment, the method for configuring a power distribution box based on grid integration includes:

[0093] S1. Receive a power configuration instruction, and identify a distribution box based on the power configuration instruction, wherein the distribution box includes: a main input terminal and a main output terminal, and the main input terminal is connected to the new power input terminal, the reserve power input terminal, and the mains input terminal, wherein the reserve power input terminal is connected to the pre-built reserve power supply via a pre-built cable, the new power input terminal is initially in the on state, and the reserve power input terminal and the mains input terminal are initially in the off state.

[0094] It should be explained that the power configuration instruction is an instruction issued by an electrical technician. For example, Xiao Zhang is an electrical technician who needs to configure the input terminals from different power sources in the distribution box. Therefore, Xiao Zhang issues a power configuration instruction, and the power configuration instruction contains a specific number or code, so the corresponding distribution box can be identified by the specific number or code. The distribution box is a device for distributing and managing electricity. The total input terminal refers to: the main power terminal in the distribution box that is connected to multiple upper power input terminals (such as: new power input terminal, reserve power input terminal and mains input terminal) and is responsible for receiving electric energy from the upper power source (such as: new power supply, reserve power supply and public power grid). The total output terminal refers to: the distribution bus in the distribution box that is connected to various electrical equipment and distributes electric energy to various electrical equipment. The new power input refers to the circuit breaker in the distribution box connected to the new energy power generation equipment via wires. The opening and closing of this circuit breaker controls the transmission or cessation of power from the new energy power generation equipment to the distribution box. The reserve power input refers to the circuit breaker in the distribution box connected to the pre-built reserve power supply via wires. The mains power input refers to the circuit breaker in the distribution box connected to the public power grid via wires. The power in the public power grid is provided by the local power station. The reserve power supply is a stored energy source that provides temporary power support in the event of a main power outage, ensuring the continued operation of critical equipment.

[0095] For example, the new energy power generation equipment is a solar photovoltaic system, and the new energy power generation equipment is connected to the distribution box via a cable. When the new energy power generation equipment is connected to the distribution box, the electricity generated by the new energy power generation equipment can be directly supplied to the user load or used with the reserve power supply. It can also charge the reserve power supply when the load's demand for electricity is small. The reserve power supply is a battery energy storage system, and the reserve power supply is connected to the distribution box via a cable. The connection between the reserve power supply and the distribution box can provide a continuous power supply when the new energy power generation equipment is insufficient or the load fluctuates greatly. The public power grid is an electric power system managed by the government or power company. The distribution box is connected to the public power grid via an incoming cable. The connection between the public power grid and the distribution box can provide a stable and reliable power supply to the distribution box when the new energy power generation equipment is insufficient or the reserve power supply is insufficient.

[0096] It should be understood that the embodiment of the present invention connects the new energy power generation equipment, the reserve power supply and the public power grid to the distribution box, and adjusts the opening status of the new power input terminal, the reserve power input terminal and the mains input terminal, so that when the distribution box corresponds to different load conditions, one or more of the new power generation equipment, the reserve power supply and the public power grid can simultaneously transmit electric energy to the distribution box, thereby ensuring stable power supply and improving power utilization.

[0097] S2. Identify a power management mechanism, wherein the power management mechanism includes: an electric power analyzer, a temperature sensor, and a battery monitoring system.

[0098] It should be explained that the power management mechanism is a device that integrates an electric power analyzer, a temperature sensor, and a battery monitoring system. The electric power analyzer is a multifunctional power meter. Optionally, an Acrel APM830 can be used as the multifunctional power meter. It is used to collect the voltage, current, power, power factor, and frequency of the total input terminal. The technology for collecting the voltage, current, power, power factor, and frequency of the total input terminal is existing technology and will not be described in detail here. The temperature sensor is a sensor used to measure the surface temperature of the output terminal. The battery monitoring system is a BMS battery system used to monitor and manage the battery status of the reserve power supply. The battery status includes but is not limited to: power supply voltage, power supply temperature, and power supply charge. The electric power analyzer is pre-installed at a first specific location on the total input terminal, the temperature sensor is pre-installed at a second specific location on the total output terminal, and the battery monitoring system is pre-installed at a third specific location on the reserve power supply. The first specific location, the second specific location, and the third specific location are pre-set by the electrical technician corresponding to the distribution box.

[0099] S3. Based on the electric power analyzer in the power management mechanism, the voltage time sequence, current time sequence, power time sequence, power factor time sequence and frequency time sequence of the total input terminal in the distribution box are obtained.

[0100] In detail, the power analyzer in the power management mechanism and the acquisition of the voltage time sequence, current time sequence, power time sequence, power factor time sequence and frequency time sequence of the total input terminal in the distribution box include:

[0101] Start the electric power analyzer, take the start time of the electric power analyzer as the starting point and record the time in real time to obtain the analysis time;

[0102] Based on the preset measurement time interval and the electric energy power analyzer, the total input end is monitored until the analysis time reaches the preset analysis time threshold, and the voltage time series, current time series, power time series, power factor time series and frequency time series are obtained.

[0103] For example, if the power analyzer is started at 10:00:00, the time is recorded in real time starting at 10:00:00. At 10:00:01, the analysis time is 1 second, and at 10:00:02, the analysis time is 2 seconds. Optionally, the measurement interval is 0.2 seconds, and the analysis time threshold is 2 seconds. If the preset measurement time interval is 0.2s, the voltage, current, input power, power factor and frequency of the total input terminal are monitored separately every 0.2s using the electric power analyzer to obtain a voltage, a current, an input power, a power factor and a frequency. When the monitoring process is completed, all voltages, all currents, all input powers, all power factors and all frequencies obtained in the monitoring process are summarized to obtain multiple voltages, multiple currents, multiple input powers, multiple power factors and multiple frequencies. The multiple voltages are sorted in the order of acquisition time to obtain a voltage time series, and the multiple currents are sorted in the order of acquisition time to obtain a current time series, and the multiple input powers are sorted in the order of acquisition time to obtain a power time series, and the multiple power factors are sorted in the order of acquisition time to obtain a power factor time series, and the multiple frequencies are sorted in the order of acquisition time to obtain a frequency time series.

[0104] S4. Calculate power stability based on the voltage time sequence, current time sequence, power time sequence, power factor time sequence, and frequency time sequence.

[0105] Specifically, the calculation of power stability based on voltage time series, current time series, power time series, power factor time series, and frequency time series includes:

[0106] Calculating a power factor change according to a power factor time series, wherein the power factor time series includes n power factors;

[0107] Calculating an average voltage value based on a voltage time series, wherein the voltage time series includes n voltage values, and the average voltage value is an average of the n voltage values;

[0108] The voltage regulation index is calculated based on the power factor change and the average voltage value. The calculation formula is as follows:

[0110] Among them, V adj Indicates voltage regulation index, ΔPF indicates power factor change, U avg represents the average voltage value, and || represents the absolute value;

[0111] Obtain an average current value, an average power value, and a maximum frequency value based on a current time series, a power time series, and a frequency time series, wherein the current time series includes n current values;

[0112] The following operations are performed for each current value in the current time series:

[0122] Calculate power stability based on voltage regulation index, current response factor, and frequency deviation.

[0123] It should be explained that the voltage value and current value refer to: the voltage value of the total input terminal and the current value of the total input terminal measured by the electric power analyzer, respectively. The voltage regulation index reflects the degree to which the power factor changes with the voltage fluctuation when the voltage at the total input terminal fluctuates. The larger the voltage regulation index, the greater the degree to which the power factor changes with the voltage fluctuation. The average current value refers to: the average value of n current values. The current response coefficient reflects the response speed of the current to load fluctuations. The larger the current response coefficient, the slower the current response speed to load fluctuations. The average power value is the average value of the n power values ​​in the power time series, and the maximum frequency value is the maximum value of the n frequency values ​​in the frequency time series. The frequency deviation reflects the degree of influence of the frequency fluctuation of the total input terminal on the corresponding power of the total input terminal. The larger the frequency deviation, the greater the influence of the frequency fluctuation of the total input terminal on the corresponding power of the total input terminal.

[0124] In detail, the calculation of the power factor variation according to the power factor time sequence includes:

[0125] Extract the i-th power factor from the power factor time series, where the initial value of i is 1;

[0126] Determining an (i+1)th power factor based on the (i)th power factor, wherein the (i+1)th power factor is adjacent to the (i)th power factor in the power factor time sequence and lags behind the (i)th power factor;

[0127] The power factor change rate is calculated based on the i-th power factor and the i+1-th power factor. The calculation formula is as follows:

[0128]

[0129] in, Indicates the rate of change of power factor, PF i and PF i+1 are the i-th power factor and the i+1-th power factor respectively, || refers to the absolute value;

[0130] Integrate the power factor change rate into a power factor data packet, store the power factor data packet in a pre-built power memory to obtain an updated power memory, set I=i+1, take I as i, use the updated power memory as the power memory, and return to the step of extracting the i-th power factor from the power factor time series until I=n-1;

[0131] extracting a plurality of power factor change rates from an updated power memory;

[0132] Obtaining a maximum value and a minimum value based on multiple power factor change rates, wherein the maximum value and the minimum value are respectively the maximum power factor change rate and the minimum power factor change rate among the multiple power factor change rates;

[0133] The power factor change is calculated based on the maximum and minimum change values. The calculation formula is as follows:

[0134]

[0135] Where ΔPF represents the power factor change, Indicates the maximum value of the change, Indicates the minimum change.

[0136] For example, since the initial value of i is 1, the first-ranked power factor is extracted from the power factor time sequence to obtain the first power factor. Based on the first power factor, the second power factor is confirmed in the power factor time sequence. If the first power factor is 0.3 and the second power factor is 0.45, the power factor change rate is 0.5. The power factor change rate is integrated as data into a power factor data packet, and the power factor data packet is stored in the power memory to obtain an updated power memory. Then, the second power factor is extracted from the power factor time sequence. And so on. If there are 10 power factors in the power factor time sequence, until the ninth power factor is extracted and the updated power memory corresponding to the ninth power factor is obtained, all previously stored power factor data packets are extracted from the updated power memory to obtain multiple power factor data packets.

[0137] It should be noted that the power factor data packet stores data on the power factor rate of change, and the technology for integrating the power factor rate of change into the power factor data packet is prior art and will not be further described here. The power memory is used to store the power factor data packet, and the updated power memory is the power memory after the power factor data packet is stored. The power factor change reflects the degree of fluctuation of the total input power factor; the greater the power factor change, the greater the fluctuation of the total input power factor.

[0138] In detail, the calculation formula of the power stability is as follows:

[0139]

[0140] Where λ represents the power stability and tanh is the hyperbolic tangent function.

[0141] It should be explained that power stability reflects the stability of the power supply at the total input end. The greater the power stability, the more stable the power supply at the total input end.

[0142] S5. Calculate the load safety of the total output end in the distribution box based on the electric power analyzer and the temperature sensor.

[0143] In detail, the calculation of the load safety degree of the total output end in the distribution box based on the electric power analyzer and the temperature sensor includes:

[0144] Obtain load power timing based on measurement time interval, analysis time threshold, electric power analyzer and total output terminal;

[0145] Start the temperature sensor, take the time of starting the temperature sensor as the starting point and record the time in real time to obtain the temperature test time;

[0146] The temperature of the total output end is monitored based on the measurement time interval and the temperature sensor until the temperature test time reaches the preset temperature test threshold, and the load temperature timing is obtained;

[0147] Obtaining an average load temperature value and an average load power value based on the load temperature time series and the load power time series, wherein the load temperature time series includes n load temperature values, and the average load temperature value is an average value of the n load temperature values, wherein the load power time series includes n load power values, and the average load power value is an average value of the n load power values;

[0148] Calculate the load safety degree based on the average load temperature value and the average load power value. The calculation formula is as follows:

[0149]

[0150] Among them, ψ represents the load safety factor, Indicates the average load power value, Indicates the average load temperature value, T0 is the preset reference temperature.

[0151] It should be understood that the method of obtaining load power timing based on measurement time interval, analysis time threshold, electric power analyzer and total output end is the same as the method of obtaining power timing using measurement time interval, analysis time threshold, electric power analyzer and total input end, and will not be repeated here.

[0152] For example, if the preset measurement time interval is 0.2s, the temperature sensor is used to monitor the load temperature every 0.2s to obtain a load temperature. When the monitoring process ends, all load temperatures obtained during the monitoring process are summarized to obtain multiple load temperatures. The multiple load temperatures are sorted in the order of acquisition time to obtain the load temperature time series. If the temperature sensor is started at 10:00:00, 10:00:00 is used as the starting point and the time is recorded in real time. At 10:00:01, the temperature test time is 1 second, and at 10:00:02, the temperature test time is 2 seconds. Optionally, the temperature test threshold is 2s.

[0153] It should be clarified that load temperature refers to the surface temperature of the output terminal. The load safety factor reflects the safety of the distribution box's total output terminal when distributing electrical energy. The greater the load safety factor, the safer the distribution box's total output terminal is. The reference temperature is a value set by electrical technicians based on historical data. Optionally, the average of the load temperatures of the total output terminals of multiple distribution boxes that have been in a safe state historically can be used as the reference temperature.

[0154] S6. Calculate the energy allocation rate based on power stability and load safety.

[0155] In detail, the calculation formula of the energy allocation rate is as follows:

[0156]

[0157] Among them, ω represents the energy allocation rate and e is a natural constant.

[0158] It should be explained that the energy configuration rate reflects the reliability of the current power configuration status of the distribution box. The higher the energy configuration rate, the higher the reliability of the power configuration status of the distribution box.

[0159] S7. Use the battery monitoring system to evaluate the energy storage efficiency of the reserve power source to obtain an energy reserve value.

[0160] Specifically, the battery monitoring system is used to evaluate the energy storage efficiency of the reserve power source to obtain the energy reserve value, including:

[0161] Use the battery monitoring system to obtain the power supply voltage, power supply temperature and power supply capacity of the reserve power supply;

[0162] The energy reserve value is calculated based on the power supply voltage, power supply temperature and power supply capacity. The calculation formula is as follows:

[0163]

[0164] Among them, B cb Indicates the energy reserve value, U cbIndicates the power supply voltage, T cb Indicates the power supply temperature, Q CB Indicates the power level.

[0165] It should be noted that the use of a battery monitoring system to obtain the reserve power supply's power supply voltage, power supply temperature, and power supply capacity is conventional technology and will not be further elaborated here. The power supply voltage refers to the voltage of the reserve power supply, the power supply temperature refers to the surface temperature of the reserve power supply, and the power supply capacity refers to the power supply capacity of the reserve power supply. The energy reserve value reflects the reserve power supply's ability to provide stable power. The larger the energy reserve value, the greater the reserve power supply's ability to provide stable power.

[0166] S8. Based on the energy configuration rate and energy reserve value, the distribution box is configured for grid integration to obtain the target distribution box. The target distribution box is used as the distribution box, and the process returns to the step of obtaining the voltage timing, current timing, power timing, power factor timing and frequency timing of the total input end of the distribution box based on the electric power analyzer in the power management mechanism, until the pre-built configuration end instruction is received to complete the power configuration of the distribution box.

[0167] It should be explained that the configuration end instruction is initiated by an electrical technician. For example, when the distribution box needs to be inspected or components need to be replaced, the power configuration cycle of the distribution box needs to be stopped. Therefore, the electrical technician initiates the configuration end instruction to end the power configuration of the distribution box.

[0168] For example, after obtaining the distribution box, return to the step of obtaining the voltage timing, current timing, power timing, power factor timing and frequency timing of the total input end based on the electric power analyzer and distribution box in the power management mechanism, and then obtain the voltage timing, current timing, power timing, power factor timing and frequency timing again for analysis, and then repeat the cycle of grid integration configuration of the distribution box, so as to adjust the status in near real time, thereby improving energy utilization.

[0169] Specifically, the grid integration configuration of the distribution box based on the energy configuration rate and the energy reserve value to obtain the target distribution box includes:

[0170] comparing the energy allocation rate with a preset allocation threshold;

[0171] If the energy configuration rate is greater than or equal to the configuration threshold, the distribution box is used as the target distribution box;

[0172] If the energy allocation rate is less than the allocation threshold, the energy reserve value is compared with the preset reserve threshold;

[0173] If the energy reserve value is greater than or equal to the reserve threshold, the reserve power input terminal is turned on to obtain the updated power input terminal, and the target distribution box is identified based on the updated power input terminal and the distribution box;

[0174] If the energy reserve value is less than the reserve threshold, the reserve power input terminal is opened to obtain the updated power input terminal, and the mains input terminal is opened to obtain the updated mains input terminal. The target distribution box is confirmed based on the updated power input terminal, the updated mains input terminal and the distribution box.

[0175] It should be explained that the updated power input terminal refers to the reserve power input terminal after it is turned on, and the updated mains input terminal refers to the mains input terminal after it is turned on.

[0176] It is understandable that the identification of the target distribution box based on the updated power input terminal and the distribution box means that when it is confirmed that the electric energy of the reserve power supply flows into the main input terminal of the distribution box through the updated power input terminal, the distribution box at this time is the target distribution box. The identification of the target distribution box based on the updated power input terminal, the updated mains input terminal, and the distribution box means that when it is confirmed that the electric energy of the reserve power supply flows into the main input terminal of the distribution box through the updated power input terminal and the electric energy of the public power grid flows into the main input terminal of the distribution box through the updated mains input terminal, the distribution box at this time is the target distribution box.

[0177] It should be explained that the configuration threshold is a value set by the electrical technician based on historical power supply conditions, and is optionally set to 8%. The reserve threshold is a value set by the electrical technician based on historical reserve power conditions, and is optionally set to 0.4.

[0178] The present invention is to solve the problem described in the background technology. The present invention receives a power configuration instruction and identifies a distribution box based on the power configuration instruction, wherein the distribution box includes: a total input terminal and a total output terminal, and the total input terminal is connected to the new power input terminal, the reserve power input terminal and the mains input terminal, wherein the reserve power input terminal is connected to the pre-built reserve power supply through a pre-built cable, the initial state of the new power input terminal is the on state, and the initial state of the reserve power input terminal and the initial state of the mains input terminal are both the off state. It can be seen that the embodiment of the present invention connects the new energy, the reserve power supply and the mains power to the distribution box at the same time, thereby facilitating the subsequent switching of the new power input terminal, the reserve power input terminal and the mains input terminal. The power supply status of different power sources is configured in different situations, thereby improving the energy utilization efficiency of the power source corresponding to the distribution box, and then confirming the power management mechanism, wherein the power management mechanism includes: an electric power analyzer, a temperature sensor and a battery monitoring system. It can be seen that the embodiment of the present invention, by confirming the power management mechanism, is convenient for the subsequent use of the electric power analyzer, the temperature sensor and the battery monitoring system to automatically obtain the status of the total input terminal in the distribution box, the status of the total output terminal in the distribution box and the status of the reserve power supply corresponding to the distribution box, thereby improving the degree of automation of the power configuration of the distribution box, and obtaining the voltage timing, current timing, power timing and power timing of the total input terminal in the distribution box based on the electric power analyzer in the power management mechanism. Factor timing and frequency timing, it can be seen that the embodiment of the present invention monitors the voltage, current, power, power factor and frequency of the total input end over a period of time, so as to facilitate the subsequent evaluation of the stability of the electric energy provided by the total input end, and calculates the power stability according to the voltage timing, current timing, power timing, power factor timing and frequency timing. It can be seen that the embodiment of the present invention calculates the power stability by comprehensively considering the changes in voltage, current, power, power factor and frequency, and evaluates the stability of the electric energy provided by the total input end. The load safety of the total output end in the distribution box is calculated based on the electric power analyzer and the temperature sensor. It can be seen that the embodiment of the present invention evaluates the total output of the distribution box by obtaining the load power and load temperature of the total output end in the distribution box. The safety level of the terminal when distributing electric energy, so as to facilitate the subsequent calculation of the energy configuration rate according to the load safety, and calculate the energy configuration rate according to the power stability and load safety. It can be seen that the embodiment of the present invention evaluates the configuration effect of the power supply by comprehensively considering the power stability and load safety, improves the safety of the distribution box during operation, and uses the battery monitoring system to evaluate the energy storage efficiency of the reserve power supply to obtain the energy reserve value. It can be seen that the embodiment of the present invention evaluates the energy reserve value of the reserve power supply through the battery monitoring system, which facilitates the subsequent more accurate grid co-integration configuration of the distribution box according to the status of the reserve power supply, and performs grid co-integration configuration on the distribution box based on the energy configuration rate and the energy reserve value to obtain the target distribution box, and uses the target distribution box as the distribution box.Returning to the step of obtaining the voltage timing, current timing, power timing, power factor timing and frequency timing of the total input terminal in the distribution box based on the electric energy power analyzer in the power management mechanism, until the pre-built configuration end instruction is received, the power configuration of the distribution box is completed. It can be seen that the embodiment of the present invention returns to the step of obtaining the voltage timing, current timing, power timing, power factor timing and frequency timing of the total input terminal in the distribution box based on the electric energy power analyzer in the power management mechanism, thereby cyclically configuring the power supply according to the status of the distribution box, improving the real-time and automation level of the power configuration of the distribution box, and thus improving the safety of the distribution box during operation. Therefore, the present invention can improve the automation level of the power configuration of the distribution box, improve the safety of the distribution box during operation and the energy utilization efficiency of the power supply corresponding to the distribution box.
