Description

Technical Field

[0001] The present application relates to the technical field of power supply and distribution scheduling, and specifically to a power distribution control method and system, and electronic equipment for multiple power supply areas. Background Art

[0002] In the context of the coordinated advancement of new urbanization and new infrastructure construction, the power Internet of Things (IoT) faces multi-dimensional load management challenges. Especially when multiple power supply areas simultaneously carry out large-scale projects such as subway tunnel excavation and prefabricated component production, the construction equipment presents the load characteristics of "high load use and high frequency use", resulting in power fluctuations of up to megawatts in the regional power grid. This strong time-varying load not only causes power quality problems such as voltage flicker and harmonic pollution, but also poses a severe test to the reliability of regional power supply. The static load prediction algorithm used by the traditional distribution control system is difficult to adapt to the dynamic coupling relationship between the commissioning status of equipment on the construction site and the power demand, and often causes the dual resource mismatch problem of overload tripping and capacity redundancy.

[0003] In the existing technology, although some methods try to adjust the power supply strategy by monitoring the power load, these methods often lack the refined management of specific power equipment, especially the power demand prediction and regulation capabilities of temporary high-power power equipment such as power equipment. In addition, the existing power distribution control system usually relies on historical data for prediction and cannot respond to sudden changes in power demand at the construction site in real time, resulting in a slow response speed of the power supply system, which is difficult to meet the real-time and flexibility requirements of modern construction sites for power supply.

[0004] Therefore, how to monitor and predict the power demand of electrical equipment in the power supply area in real time, and dynamically adjust the power distribution strategy for construction sites in the power supply area according to actual conditions to improve the power consumption stability of the power supply area is a technical problem that needs to be solved in this field. Summary of the invention

[0027] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] Figure 1 The figure shows a schematic diagram of the method steps of a power distribution control method for multiple power supply areas provided by an embodiment of the present application. The present application provides a power distribution control method for multiple power supply areas. In one embodiment, as Figure 1 As shown, the power distribution control method for multiple power supply areas includes: Step 110: Collect the number of construction sites in multiple power supply areas.

[0029] In this step, the upper control system of power distribution controls the power dispatch of each power supply area in the city, and can intelligently dispatch the power and electric energy of each power supply area in the city, and pre-plan multiple power supply areas consisting of construction sites in the city, that is, the area covered by the power supply area only includes construction sites, and does not include other power consumption scenarios. For the collection of the number of construction sites, the number of construction site areas in the power supply area is set in the city's planning data, or the number of construction sites in each power supply area is monitored and identified through the city's Skynet system.

[0030] Step 120: Mark the power supply area where the number of construction sites is greater than a first preset number as an area to be compensated.

[0031] In this step, the number of construction sites in each power supply area is set to be collected once a day or several days. When the number of construction sites in some power supply areas is too large to exceed the first preset number, it indicates that the power consumption and power load of these power supply areas are large. A large number of electrical equipment need to be powered and charged in each construction site in the area to be compensated. These power supply areas are marked as areas to be compensated, and it may be necessary to compensate for electricity for all construction sites in the power supply area later.

[0032] Step 130: Monitor the change data of the electrical equipment at each construction site in the area to be compensated within a first preset time period.

[0033] In this step, the entrance and exit of the construction site are equipped with induction gates that can be used to collect and upload the entry and exit data of the construction site. The central control system of the construction site will also record the entry and exit data of the electrical equipment, and the change data will be obtained by aggregating multiple data sources. The first preset time period is set to half a day or a day, and the change data of the electrical equipment entering the construction site is continuously monitored within half a day or a day. The change data includes the number, model, type, etc. of electrical equipment entering all construction sites in the area to be compensated. The electrical equipment referred to in this application includes high-power electrical equipment such as new energy cranes, new energy excavators, new energy rotary drilling rigs, charging piles, and power supply piles.

[0034] Step 140: based on the change data, if the increasing trend of the number of electrical equipment at the construction site within the second preset time period is greater than the preset trend, the construction site is marked as a target construction site, and the power distribution parameters corresponding to each electrical equipment in the target construction site are retrieved.

[0035] In this step, the power distribution parameters correspond to the types of electrical equipment, and the length of the second preset time period is less than the length of the first preset time period. When the rising trend of the number of on-site equipment in a construction site in the area to be compensated is greater than the preset trend, it can be determined that the number of electrical equipment in the construction site in the area to be compensated is gradually increasing and the increase is large, and it is necessary to start power compensation for the construction site, and mark the construction site as the target construction site, that is, it is necessary to start power compensation for the target construction site. The preset trend can be set as the slope corresponding to the rising speed of the number of on-site equipment over time is 1.2, 1.3, or 1.4. If the slope of the number of on-site equipment rising over time is greater than 1.2, 1.3, or 1.4, it is determined that the rising trend is greater than the preset trend, and it is necessary to start power compensation scheduling for the target construction site. The power distribution parameters correspond to the types of electrical equipment, and the length of the second preset time period is less than the length of the first preset time period. For example, the first preset time period is set to 24 hours, and the second preset time period is set to 6 hours. The second preset time period is mainly used to judge the trend of changes in the number of electrical equipment at each construction site. The power distribution parameters are pre-set and related to the parameters of the power-consuming equipment, that is, the power distribution parameters are strongly correlated with the electrical property parameters of the power-consuming equipment. The higher the power consumption corresponding to the type of power-consuming equipment, the larger the power distribution parameters. For example, the power distribution parameters of new energy cranes are 1.4, the power distribution parameters of new energy excavators are 1.3, the power distribution parameters of new energy rotary drilling rigs are 1.4, the power distribution parameters of charging piles are 1.5, and the power distribution parameters of power supply stations are 1.6. The above parameters are only examples, and the corresponding relationship can be pre-set according to actual conditions or expert advice. Heavy equipment with poor mobility, such as new energy cranes, new energy excavators, and new energy rotary drilling rigs, generally work continuously for many days or even weeks on the construction site. Their mobility is poor, so they will be charged and powered on at the construction site. Therefore, it is necessary to compensate for electricity to the target construction site.

[0036] Step 150: Obtain the continuous operation duration of each electrical equipment in the target construction site within a preset reference time period, and obtain a power distribution correction coefficient according to the continuous operation duration.

[0037] In this step, the power distribution correction coefficient increases with the increase of continuous operation duration. The power distribution parameters are further corrected to match the actual working conditions of the power equipment on the construction site. The power distribution correction coefficient increases with the increase of continuous operation duration. The preset reference time period is set as needed, and is generally set to a 2-hour time period or a 3-hour time period. The longer the continuous operation duration, the longer the high-load operation time of the power equipment, so further coefficient correction is required, that is, the larger the power distribution correction coefficient is obtained. The correspondence between the continuous operation duration and the power distribution correction coefficient is preset. The continuous operation duration is 1 hour, and the corresponding power distribution correction coefficient is 1.1; the power distribution correction coefficient increases by 0.03 for every 1 minute increase in the continuous operation duration. In some embodiments, if the electric equipment stops working for less than 10 minutes during operation, it is not considered as stopped operation, but still considered as continuous operation. For example, if the electric equipment stops working for 1 hour and then continues to work for 3 minutes, the accumulation of continuous operation time will not be interrupted, but the accumulation of continuous operation time will continue until the electric equipment stops working for more than 10 minutes. This is because the electric equipment stopping working for less than 10 minutes can be considered as a temporary adjustment, rather than interrupting continuous operation. The setting of this step makes the power distribution correction coefficient strongly correlated with the continuous operation time, so that the longer the high-load operation time of the electric equipment is, the more power distribution adjustment is obtained.

[0038] Step 160: Correct the power distribution parameters corresponding to each power-consuming device based on the power distribution correction coefficient to obtain the power distribution compensation coefficient corresponding to each power-consuming device.

[0039] In this step, the power distribution correction coefficient and the power distribution parameter are multiplied to obtain the power distribution compensation coefficient. For example, the power distribution parameter of the new energy crane is 1.4, and the continuous operation time is 1.5 hours, corresponding to the power distribution correction coefficient of 1.2, and the final power distribution compensation coefficient is 1.68.

[0040] Step 170: retrieve the reference power consumption corresponding to each electrical equipment in the target construction site.

[0041] In this step, the reference power is the power consumption of the power-consuming equipment in the last preset unit time. The preset unit time can be set to 1 hour, 2 hours, or 3 hours. For example: if the preset unit time is 1 hour, a new energy crane consumes 40 degrees of electricity in the past hour, then the reference power of the new energy crane is 40 degrees; if a power supply pile consumes 100 degrees of electricity in the past hour, then the reference power of the power supply pile is 100 degrees; if a new energy excavator consumes 50 degrees of electricity in the past hour, then the reference power of the new energy excavator is 50 degrees.

[0042] Step 180: Obtain the distribution control power of the area to be compensated for the target construction site based on the power distribution compensation coefficients and power reference power of all power-consuming equipment in the target construction site.

[0043] In this step, the distribution compensation coefficient and the reference power are multiplied to obtain the distribution compensation amount for a single power-consuming device. For example, if the reference power is 100 degrees and the distribution compensation coefficient is 1.68, the distribution control power corresponding to the power-consuming device is 168 degrees. Then, the distribution compensation amounts corresponding to all power-consuming devices are added together to obtain the distribution control power of the target construction site.

[0044] Step 190: The area to be compensated distributes the regulated power to the target construction site for storage or use.

[0045] When applied, this embodiment can intelligently regulate the power distribution of multiple power supply areas. By monitoring and analyzing the number of construction sites in each power supply area and the in-and-out data of power equipment, the target construction site with high power load is identified, and power compensation is performed for the power equipment in the target construction site. The power distribution parameters are adjusted and corrected according to the changes in the number of power equipment entering the site and the duration of continuous operation, and the power distribution compensation coefficient of each power equipment is calculated. Combined with the power reference power corresponding to the type, the power distribution compensation required for each power equipment in the target construction site is calculated. Finally, the power distribution compensation amounts of all power equipment in the target construction site are superimposed to obtain the required power distribution and control power for the entire target construction site, thereby realizing the precise allocation and optimized management of power resources. This method improves the efficiency of power dispatching, ensures the stability of power supply, and is particularly suitable for power supply scenarios of new energy power equipment. Traditional power distribution strategies are mainly based on historical data for power distribution, and cannot calculate and perform predictive power distribution based on real-time data. However, this application can learn the actual power load situation of a construction site based on the real-time data of a construction site in a certain power supply area, so as to perform predictive compensation power distribution for the target construction site to avoid power outages in the area to be compensated due to high-load power consumption at the construction site. The larger the distribution control power calculated for the target construction site, the greater the real-time power consumption of the target construction site, and the probability of power consumption at the target construction site increases accordingly, thereby performing predictive power compensation. The compensated distribution control power can be used directly or stored in an electric energy storage device.

[0046] Figure 2 FIG. 1 is a schematic diagram of a specific method and steps for obtaining change data. In one embodiment, Figure 2 As shown, step 130 includes: Step 131, obtaining the import and export image data of the Skynet monitoring system of the construction site (import and export) within a first preset time period.

[0047] Step 132: Calculate the change data of the electrical equipment entering the construction site in the import and export image data based on image recognition.

[0048] This embodiment realizes the automation and intelligent management of construction site import and export monitoring. The Skynet monitoring system automatically collects image data within a specific time period, and uses image recognition technology to analyze these data, thereby automatically identifying and calculating the data information of the electrical equipment entering and leaving the construction site. For example, the monitoring equipment at the construction site entrance and exit monitored that 10 charging piles were transported into the construction site within 1 day. It not only improves the efficiency of data collection and reduces human errors, but also provides step 140 with real-time and accurate data trends on the flow of on-site quantity changes. In addition, the change data of the electrical equipment can be further confirmed or corrected through the equipment acceptance form stored in the central control system of the construction site.

[0049] Figure 3 The figure shows a schematic diagram of specific method steps when the rising trend of the number of entries is greater than the preset trend. Figure 3 As shown, step 140 includes: Step 141: within a first preset time period, equally divide the first preset time period into a plurality of time periods as a plurality of second preset time periods.

[0050] Determine whether the increase in the number of entry points in the adjacent second preset time period is greater than the preset difference. If so, execute step 142: Step 142: Retrieve power distribution parameters of the electrical equipment.

[0051] This embodiment refines the change in the number of on-site equipment, and can further finely manage and analyze the in-and-out data of power equipment, as well as an intelligent response mechanism based on these data. The first preset time period is equally divided into multiple second preset time periods, so that the time is finely divided, so that the monitoring of the number of power equipment on-site is more detailed, and a more accurate time frame is provided for subsequent data analysis. By comparing the rising difference in the number of on-site equipment between adjacent second preset time periods with the preset difference, real-time monitoring of the dynamics of the on-site power equipment is achieved. The increasing trend of the number of power equipment on-site can be automatically identified. If the increasing trend is greater than the preset trend, it can be determined that the number of power equipment on the construction site is gradually increasing and the increase is large, and it is necessary to start power compensation for the construction site, and the construction site is marked as a target construction site.

[0052] Figure 4 The figure shows a schematic diagram of the specific method steps for retrieving the duration of continuous operation. Figure 4 As shown, step 150 includes: Step 151: Obtain operating parameters of the electrical equipment within a single standard operating time after entering the construction site.

[0053] Step 152: retrieve the continuous operation duration from the operating condition parameters.

[0054] In this embodiment, a single standard operation time of the electrical equipment is preset, and the single standard operation time is two hours, three hours or half a day, which refers to a standard operation time of the electrical equipment at the construction site within a single working day. During a single standard operation time, the electrical equipment may perform high-load operations continuously or intermittently. During the operation of the electrical equipment, the on-board computer of the electrical equipment will record various operating parameters, including the continuous operation time.

[0055] Figure 5 The figure shows a schematic diagram of the specific method steps for accumulating the continuous operation time. Figure 5 As shown, step 152 includes: Step 1521: Obtain the load operation duration of the electrical equipment during a single standard operation duration, when the electrical equipment performs a construction site operation with an execution power greater than a preset power.

[0056] Step 1522: Accumulate the load operation duration within a single standard operation duration to obtain the continuous operation duration.

[0057] In this embodiment, the determination of the continuous operation duration within a single standard operation duration is further refined, that is, the electrical equipment will accumulate the continuous operation duration only when it is greater than the preset power, that is, the load operation duration begins to be recorded when it is greater than the preset power, and the load operation duration corresponding to the high power is continuously accumulated to finally obtain the continuous operation duration. Specifically, electrical equipment that performs work exceeding the preset power is identified as high-power operation, such as excavators performing high-load excavation work, cranes performing high-load lifting work, charging piles performing high-power charging, and power supply piles performing high-power power supply, while low-power basic functions (such as low-power actions such as driving, rotation, counterweight adjustment, etc.) will not be calculated into the continuous operation duration, which further enables the power distribution correction coefficient corresponding to the continuous operation duration to more accurately match the actual working conditions of the electrical equipment.

[0058] Figure 6 FIG. 1 is a schematic diagram of the method steps for correcting the reference power used. Figure 6 As shown, after step 170, the method further includes: Step 1701: Obtain a reference power correction coefficient according to the continuous operation duration. In this step, the reference power correction coefficient is greater than 1 and increases as the continuous operation duration increases.

[0059] Step 1702: Correct the reference power based on the reference power correction coefficient.

[0060] Based on step 1701 and step 1702, step 180 includes: Step 181: Obtain the distribution control power for the power equipment in the area to be compensated based on the distribution compensation coefficient and the corrected reference power.

[0061] In this embodiment, a reference power correction coefficient that is strongly correlated with the duration of continuous operation is used to correct the reference power consumption, so that the corrected reference power consumption is strongly correlated with the duration of continuous operation, thereby further making the final distribution control power correlated with the duration of continuous operation, that is, the longer the duration of continuous operation, the more distribution control power is obtained. When applied, the corresponding relationship between the duration of continuous operation and the reference power correction coefficient is preset. The duration of continuous operation is 1 hour, and the corresponding reference power correction coefficient is 1.1; the distribution correction coefficient increases by 0.1 for every 0.5 hour increase in the duration of continuous operation.

[0062] Figure 7 FIG. 1 is a schematic diagram of a specific method for calculating the additional power distribution. Figure 7 As shown, after step 180, the power distribution control method for multiple power supply areas further includes: Step 1801: retrieve the historical power consumption data of the power-consuming equipment within a preset historical power consumption period.

[0063] Step 1802: Analyze the average daily power consumption of the power-consuming equipment in a preset historical power consumption period based on the historical power consumption data.

[0064] Step 1803: Obtain an electricity consumption ratio based on the average daily electricity consumption and the reference power consumption of the electrical equipment.

[0065] Step 1804: Obtain a corresponding additional power distribution compensation coefficient according to the power ratio; the additional power distribution compensation coefficient increases as the power ratio increases.

[0066] Step 1805: Obtain the additional distribution power according to the additional distribution compensation coefficient and the reference power.

[0067] When this embodiment is applied, first, the historical power consumption data of the power equipment in the preset historical power consumption period is retrieved, and then the historical power consumption data is analyzed to determine the average daily power consumption of the power equipment in the preset historical power consumption period, and then an electricity ratio is calculated based on the average daily power consumption of the power equipment and the reference power consumption, and an additional distribution compensation coefficient is obtained based on the electricity ratio, and the coefficient is proportional to the electricity ratio, and finally the additional distribution power is calculated based on the additional distribution compensation coefficient and the reference power consumption. This embodiment can dynamically adjust the distribution compensation by analyzing the historical power consumption data of the power equipment to improve the rationality and efficiency of power allocation and supply. By calculating the additional distribution compensation coefficient and the additional distribution power, a more accurate power distribution that is strongly correlated with the historical power consumption data can be provided for the area to be compensated, thereby improving energy utilization efficiency and reducing costs. A coefficient k is set between the additional distribution compensation coefficient and the power ratio to set the corresponding relationship between the two, and k is determined according to the type of power equipment. For example, the average daily electricity consumption of a new energy crane is 50 kWh, and the reference power is 40 kWh. The power ratio is 1.25, and the coefficient k is set to 0.3. The corresponding additional distribution compensation coefficient is 0.375, and the additional distribution power for the power equipment is 15 kWh. For another example, the average daily electricity consumption of the power supply pile is 800 kWh, the reference power is 100 kWh, the power ratio is 8, and the coefficient k is 0.35. The corresponding additional distribution compensation coefficient is 2.8, and the reference power is 100 kWh. The additional distribution power for the power equipment is 280 kWh.

[0068] Figure 8 FIG. 1 is a schematic diagram of a specific method for calculating redundant power distribution compensation power. In one embodiment, Figure 8 As shown, the power distribution control method for multiple power supply areas also includes: Determine whether the number of construction sites in the power supply area has increased to more than a second preset number. If so, execute step 200: Step 200: Calculate the average number of electrical equipment at construction sites within the power supply area.

[0069] Step 210: Obtain redundant power distribution compensation power according to the average quantity and the minimum power consumption reference power.

[0070] In this embodiment, the second preset number is greater than the first preset number. This embodiment monitors the change in the number of construction sites in the power supply area, and when the number exceeds the second preset number, it is determined that the number of construction sites in the area to be compensated is very large, and the power load of the entire area is very large. The total number of all electrical equipment corresponding to all construction sites whose increasing trend of the number of on-site entry is greater than the preset trend is counted, and then the total number is divided by the number of construction sites whose increasing trend is greater than the preset trend, and the average number can be obtained in step 200. A minimum reference power is selected from all electrical equipment, and the redundant distribution compensation power is obtained by multiplying the average number and the minimum reference power to dynamically adjust the power distribution, so as to further ensure the adequacy and stability of the power supply without causing excessive compensation power. This embodiment helps to prevent power shortages by calculating the redundant distribution compensation power based on the average number when the number of construction sites increases significantly, thereby improving the reliability and flexibility of power supply.

[0071] The present application also provides a power distribution control system for multiple power supply areas. Fig. 9 The following is a schematic diagram of the system structure of the power distribution control system in multiple power supply areas. Fig. 9 As shown, the power distribution control system for multiple power supply areas includes: a data acquisition module 901, a power distribution coefficient analysis module 902 and a power distribution compensation module 903.

[0072] The data acquisition module 901 is configured to: collect the number of construction sites in multiple power supply areas; mark the power supply areas with a number of construction sites greater than a first preset number as areas to be compensated; and monitor the change data of electrical equipment at each construction site in the area to be compensated within a first preset time period.

[0073] The power distribution coefficient analysis module 902 is communicatively connected with the data acquisition module 901, and the power distribution coefficient analysis module 902 is configured as follows: based on the change data, if the upward trend of the number of power equipment at the construction site within the second preset time period is greater than the preset trend, the construction site is marked as a target construction site, and the power distribution parameters corresponding to each power equipment in the target construction site are retrieved; the power distribution parameters correspond to the types of power equipment, and the duration of the second preset time period is less than the duration of the first preset time period; the continuous operation duration of each power equipment in the target construction site within the preset reference time period is obtained, and the power distribution correction coefficient is obtained according to the continuous operation duration; the power distribution correction coefficient increases with the increase of the continuous operation duration; the power distribution parameters corresponding to each power equipment are corrected based on the power distribution correction coefficient, and the power distribution compensation coefficient corresponding to each power equipment is obtained.

[0074] The power distribution compensation module 903 is communicatively connected with the power distribution coefficient analysis module 902, and the power distribution compensation module 903 is configured as follows: retrieving the reference power corresponding to each power-consuming equipment in the target construction site; the reference power is the power consumption of the corresponding power-consuming equipment within the last preset unit time; obtaining the distribution control power of the target construction site by the area to be compensated based on the power distribution compensation coefficient and the reference power of all power-consuming equipment in the target construction site; the area to be compensated distributes the distribution control power to the target construction site for storage or use.

[0075] When applied, this embodiment can intelligently regulate the power distribution of multiple power supply areas. By monitoring and analyzing the number of construction sites in each power supply area and the in-and-out data of power equipment, the target construction site with high power load is identified, and power compensation is performed for the power equipment in the target construction site. The power distribution parameters are adjusted and corrected according to the changes in the number of power equipment entering the site and the duration of continuous operation, and the power distribution compensation coefficient of each power equipment is calculated. Combined with the power reference power corresponding to the type, the power distribution compensation required for each power equipment in the target construction site is calculated. Finally, the power distribution compensation amounts of all power equipment in the target construction site are superimposed to obtain the required power distribution and control power for the entire target construction site, thereby realizing the precise allocation and optimized management of power resources. This method improves the efficiency of power dispatching, ensures the stability of power supply, and is particularly suitable for power supply scenarios of new energy power equipment. Traditional power distribution strategies are mainly based on historical data for power distribution, and cannot calculate and perform predictive power distribution based on real-time data. However, this application can learn the actual power load situation of a construction site based on the real-time data of a construction site in a certain power supply area, so as to perform predictive compensation power distribution for the target construction site to avoid power outages in the area to be compensated due to high-load power consumption at the construction site. The larger the distribution control power calculated for the target construction site, the greater the real-time power consumption of the target construction site, and the probability of power consumption at the target construction site increases accordingly, thereby performing predictive power compensation. The compensated distribution control power can be used directly or stored in an electric energy storage device.
