Description

Technical Field

[0001] This invention relates to the field of lighting control technology, and in particular to a method for staggered start-up control of LED lamps. Background Technology

[0002] The field of lighting control technology involves the regulation and management of lighting equipment. Core aspects include brightness control, switching control, timing control, and coordinated control of multiple lamps. This technology encompasses not only traditional control methods for incandescent and fluorescent lamps but also the control technology for LED lamps, which have been widely adopted in recent years. LED lamps, with their high efficiency and low energy consumption, have gradually become an important component of modern lighting systems. Therefore, control methods for LED lamps, especially load management in large-scale lighting systems, have become a research hotspot in the field of lighting control. Research on lighting control technology aims to achieve energy efficiency optimization, extended lamp lifespan, and rational allocation of power system load. Traditional LED lamp staggered start-up control methods refer to scheduling the start-up and shutdown times of LED lamps to avoid peak power loads caused by multiple lamps starting simultaneously. Traditional solutions use timed switching or current detection technology, employing a central control system to start multiple LED lamps in batches, ensuring that the lamp start-up process does not cause excessive impact on the power grid in a short period. The method controls the start-up time through a power management module or uses current sensing devices to adjust the switching status of the lamps in real time, thereby effectively distributing the start-up load, avoiding the concentration of grid load, and ensuring the stable operation of the lighting system.

[0003] Existing peak-shaving start-up control methods mainly rely on timed switches or current detection to start lamps in batches. This approach still cannot effectively prevent concentrated grid load when faced with a large number of lamps starting, and the dynamic changes in current are not responded to in real time or precisely adjusted. Traditional solutions rely on central control to schedule lamp start-up timing, but cannot flexibly adjust the start-up sequence based on the load stability, starting current, and voltage fluctuations of lamps in different areas. This leads to excessive concentration or uneven load distribution during peak load periods. Existing technologies fail to fully consider the physical connection paths between lamps and cannot accurately control current regulation during the start-up process, thus affecting equipment lifespan, causing grid load fluctuations, and reducing overall load management efficiency. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and propose a method for staggered start-up control of LED lamps.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a method for controlling the staggered start-up of LED lamps, comprising the following steps:

[0006] S1: Obtain information on power grid load fluctuation characteristics, lamp distribution location and lamp starting current changes. Combine the starting current value in the current sampling period with the trend of the previous period to analyze the peak starting load and filter out areas with stable load, and generate a table of stable lamp starting load areas.

[0009] S4: Based on the area path adaptation relationship group, retrieve the current current value of the path and the set safety target current, adjust the lamp start-up sequence level of the area in the list in the current cycle according to the deviation direction, and obtain the lamp pre-configuration start-up sequence control instruction set.

[0010] As a further embodiment of the present invention, the lamp start-up load stability area table includes an area number, a load stability interval identifier, and a lamp distribution characteristic coupling value; the lamp priority start-up list includes a response delay parameter, a time interval limit value, and a start-up priority label; the area path adaptation relationship group includes a physical connection path identifier, a current reference interval, and a voltage stability judgment value; and the lamp pre-configuration start-up sequence control instruction set includes a start-up sequence level code, a current adjustment direction, and a periodic configuration parameter.

[0011] As a further aspect of the present invention, the steps of establishing the lamp start-up load stability zone table are as follows:

[0012] S111: Acquire power grid load fluctuation characteristics data, lamp distribution location information and lamp start-up current change information, perform ratio calculation of start-up current value and sampling period, identify regional start-up load peak value, and generate regional start-up load peak value sequence;

[0013] S112: Call the regional load peak sequence, compare the regional load peak difference with the set stability threshold period by period, filter the time period where the continuous difference is lower than the load stability threshold, extract the corresponding regional number and time window, and obtain the load stability segment index set.

[0014] S113: Based on the starting load stable zone index set, filter the regions with load stability characteristics as manageable regions, mark the controllable interface and the regions with predictable starting load trends, and generate a lamp starting load stable zone table.

[0015] As a further aspect of the present invention, the step of obtaining the priority start list of lamps specifically includes:

[0016] S211: Call the lamp start-up load stable area table, extract the corresponding area number, time interval and original response delay, identify the area number to match each data item, and establish a set of area start-up parameters;

[0017] S212: Based on the set of regional startup parameters, sort the original response delays in ascending order, filter the regional sequence of response delays, and obtain a startup response sorting list;

[0018] S213: Call the startup response sorting list, compare the regional time interval with the set time interval upper limit, remove regions whose time interval exceeds the upper limit, and generate a lamp priority startup list.

[0019] As a further aspect of the present invention, the step of obtaining the regional path adaptation relationship group specifically includes:

[0020] S311: Call the lamp priority start list, capture the real-time current monitoring value and voltage detection device measurement value in the candidate lamp group, summarize the real-time current value and voltage value of the area, and generate the area environmental status parameters;

[0021] S312: Based on the environmental state parameters of the area, and by comparing the current value, voltage value and the safety reference value range, areas that meet the environmental restoration conditions are selected to obtain a set of usable areas for environmental control;

[0022] S313: Call the set of available environmental control areas, map the area number and connection channel according to the physical connection path between the list area and the lighting group, calculate the adaptation value of the area path, and obtain the area path adaptation relationship group.

[0023] As a further aspect of the present invention, the step of obtaining the lamp pre-configuration start-up sequence control instruction set specifically includes:

[0024] S411: Based on the area path adaptation relationship group, collect the real-time current value of the path in the current cycle, match the safety target current corresponding to each path, merge the current value and the target value according to the path number, and generate a path current offset data group.

[0025] S412: Call the path current offset data group, determine the deviation direction between the current current value of each path and the safety target current, and classify the status into exceeding the standard and meeting the standard according to the positive and negative signs of the deviation value, and obtain the current deviation direction identifier set;

[0026] S413: Based on the current deviation direction identifier set, locate the list area connected by the corresponding path, adjust the start-up sequence level of the regional lamps in the current cycle, calculate the adjustment coefficient of the start-up sequence level of the regional lamps in the current cycle, and obtain the lamp pre-configuration start-up sequence control instruction set.

[0027] As a further aspect of the present invention, the method further includes step S5:

[0028] S5: Call the pre-configured start-up sequence control instruction set of the lamps, compare the path delay data in the recovery sequence with the fluctuation rate of the current regulation signal, perform matching and filtering based on path characteristics and key time points, and output the batch start-up path and synchronous recovery table of the lamps.

[0029] The table of batch start-up paths and synchronous recovery for lighting fixtures includes path delay coefficients, synchronous setting time points, and current response characteristics.

[0030] As a further aspect of the present invention, the steps of the batch start-up path and synchronization recovery table for the lamps are specifically as follows:

[0031] S511: Call the lamp pre-configuration start-up sequence control instruction set, extract the path delay change at key time points based on the path delay data in the recovery sequence, identify the path delay fluctuation characteristics, and perform correlation analysis with the current regulation signal fluctuation rate to obtain the path delay fluctuation correlation coefficient.

[0032] S512: Based on the path delay fluctuation correlation coefficient and combined with the path characteristic parameters, perform a matching judgment operation on the path performance at key time points, filter the set of paths that meet the synchronization conditions, and obtain the synchronization path judgment value range.

[0033] S513: Call the synchronization path determination value range and compare it with the synchronization area parameters in the current adjustment signal to determine the optimal path and corresponding area parameters for batch starting of lamps, and output the batch starting path and synchronization recovery table of lamps.

[0034] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0035] In this invention, by real-time analysis of power grid load fluctuation characteristics, lamp starting current changes, and response delays, areas with relatively stable loads can be accurately identified and lamp starting timing optimized. This avoids power surges during large-scale startups and improves the operational stability of lighting facilities. By prioritizing lamp starting time intervals and response delays, lamps with sensitive and stable loads can be started first, reducing load peaks during startup. Simultaneously, real-time monitoring of current and voltage and dynamic adjustment of path adaptation relationships ensure the safety of the startup process and the accuracy of current control. This effectively avoids load concentration and uneven distribution problems, achieving optimized load management and extended equipment lifespan. Attached Figure Description

[0044] Example 1

[0045] Please see Figure 1 This invention provides a technical solution: a method for controlling the staggered start-up of LED lamps, comprising the following steps:

[0046] S1: Obtain information on power grid load fluctuation characteristics, lamp distribution location and lamp starting current changes. Combine the starting current value in the current sampling period with the trend of the previous period to analyze the peak starting load and filter out areas with stable load, and generate a table of stable lamp starting load areas.

[0047] S2: Call the lamp start-up load stable area table, extract the corresponding lamp start-up time interval and original response delay in the area, sort by response delay and exclude areas where the time interval exceeds the upper limit, and generate a lamp priority start-up list;

[0048] S3: Call the list of lamps to be started first, collect the real-time current monitoring value and voltage detection device measurement value in the candidate lamp group, compare and filter the area that meets the safety benchmark value range, and obtain the area path adaptation relationship group through the physical connection path mapping between the list area and the lamp group;

[0049] S4: Based on the regional path adaptation relationship group, retrieve the current current value of the path and the set safety target current, adjust the lamp start sequence level of the region in the current cycle according to the deviation direction, and obtain the lamp pre-configuration start sequence control instruction set.

[0051] The table of stable load zones for luminaire startup includes zone number, stable load zone identifier, and luminaire distribution characteristic coupling value. The list of priority luminaire startup includes response delay parameters, time interval limit values, and startup priority labels. The zone path adaptation relationship group includes physical connection path identifier, current reference range, and voltage stability judgment value. The luminaire pre-configuration startup sequence control instruction set includes startup sequence level code, current adjustment direction, and periodic configuration parameters. The luminaire batch startup path and synchronization recovery table includes path delay coefficient, synchronization setting time point, and current response characteristics.

[0052] Please see Figure 2 The specific steps for creating the lighting fixture start-up load stability zone table are as follows:

[0053] S111: Acquire power grid load fluctuation characteristics data, lamp distribution location information and lamp start-up current change information, perform ratio calculation of start-up current value and sampling period, identify regional start-up load peak value, and generate regional start-up load peak value sequence;

[0054] Data on power grid load fluctuation characteristics, lamp distribution location information, and current changes during lamp startup are acquired. Real-time load data of the power grid within a specified area is obtained from the Supervisory Control and Data Acquisition (SCADA) system. This data is collected with a fixed sampling period of 500 milliseconds and includes time series of active power (kW) and reactive power (kVAR). The power grid load of a certain urban road section is 500kW before lighting is started in the evening, and fluctuates over time. The precise geographic coordinates, rated power, and physical feeder numbers of all lamps in the area are obtained from the Geographic Information System (GIS) database. Area A contains 200 150W LED streetlights distributed across two... On different feeders, intelligent current sensors installed at each lamp or lamp convergence point continuously monitor the transient current response of the lamp after receiving the start command at a sampling interval of 100 milliseconds, recording the entire current change curve from zero to a steady state. For example, at the moment of start-up, the current of a 150W LED lamp rapidly rises from 0A to 2.5A within the first 50 milliseconds, and then gradually stabilizes to 0.68A within the next 150 milliseconds. The maximum current value in the current change curve at the moment of lamp start-up is determined as the start-up current value. For example, the start-up current value of the aforementioned LED lamp is 2.5A. This maximum current value occurs between 0 and 200 milliseconds after the start command is issued, and its selection is based on... Based on the experimental analysis of the starting characteristics of a large number of different types of lamps, it was found that the peak current within this time window can effectively characterize the instantaneous impact intensity of the lamp on the power grid. The starting current value is compared with a set sampling period, such as 0.1 seconds, to calculate the starting current rise rate of a single lamp. The formula is: Starting current rise rate = Starting current value / Sampling period. For the aforementioned LED lamp, its starting current rise rate is 2.5A / 0.1s = 25A / s. According to a preset geographical area division, the starting current rise rates of all lamps located in the same area are aggregated. For example, in area A, if 100 lamps start simultaneously, the total starting current rise rate in area A is... The current rise rate is 100 × 25 A / s = 2500 A / s. By comparing historical data and empirical values, the highest growth rate of the grid load on that day is compared with the rise rate of the aggregated starting current. If the aggregation rate exceeds 1.5 times the growth rate of the grid load on that day, it is determined to be the peak value of the regional starting load. For example, if the highest growth rate of the grid load on that day is 1500 A / s, and the aggregation rate of region A is 2500 A / s, which exceeds 1.5 times, then 2500 A / s is identified as the peak value of the regional starting load. The identification process is continuous and is performed once every 5 minutes. The peak values ​​of the regional starting load identified at different time points are arranged in chronological order to generate a sequence of regional starting load peak values.

[0055] S112: Call the regional load peak sequence, compare the regional load peak difference with the set stability threshold period by period, filter the time period where the continuous difference is lower than the load stability threshold, extract the corresponding regional number and time window, and obtain the load stability segment index set.

[0056] The system invokes the aforementioned regional load peak sequence, which contains the peak load values ​​of multiple regions at different time points. For example, the peak load of region A is 2500 A / s at time T1, 2350 A / s at time T2, 2300 A / s at time T3, 2280 A / s at time T4, and 2270 A / s at time T5. The system compares this sequence periodically based on a preset load stability threshold. This load stability threshold is set based on statistical analysis of historical load fluctuation data of the power grid. For example, by calculating the standard deviation of hourly load data over the past year, it is found that under normal operating conditions, the short-term load fluctuation range is within 5% of the rated load. Considering the characteristics of lighting load, the load stability threshold is set to ensure that the absolute value of the peak difference is no greater than 3% of the regional load peak, i.e., 0.03 × the regional load peak. For example, for a peak load of 2500 A / s, the stability threshold is 2500 × 0.03 = 75 A / s. The system calculates... The difference between regional load peaks in adjacent periods (e.g., every 5 minutes) within the sequence is calculated, and its absolute value is compared with a set stability threshold. For example, |T2 peak - T1 peak| = |2350 - 2500| = 150 A / s, greater than 75 A / s; |T3 peak - T2 peak| = |2300 - 2350| = 50 A / s, less than 75 A / s; |T4 peak - T3 peak| = |2280 - 2300| = 20 A / s, less than 75 A / s; |T5 peak -T4 peak value|=|2270-2280|=10A / s, less than 75A / s. Filter out time periods where the difference between peak load values ​​is consistently below the load stabilization threshold. For example, from T3 to T5, the peak difference is consistently below 75A / s. This time period is identified as a period where the load tends to stabilize. Extract the corresponding region number (e.g., region A) and the precise time window (e.g., [T3, T5]). Compile this information into a load stabilization segment index set.

[0057] S113: Based on the index set of stable start-up load segments, filter areas with stable load characteristics as manageable areas, mark controllable interfaces and areas with predictable start-up load trends, and generate a table of stable start-up load areas for lighting fixtures.

[0058] Based on the aforementioned index set of stable load segments, which contains multiple region numbers and corresponding load stabilization time windows (e.g., region A's stabilization time window is [T3, T5], and region B's is [T4, T6]), load stabilization characteristics are filtered for each region in the index set. The criterion for determining load stabilization characteristics is that within a specified time window, the fluctuation range of the region's peak load at startup does not exceed 1% of its average peak load, and this stable state lasts for at least 30 minutes. For example, if region A's average peak load at startup within the [T3, T5] time window is 2283.3 A / s, and its fluctuation range is...

[0059] |2300-2270| = 30 A / s, which is lower than 2283.3 × 0.01 = 22.83 A / s, thus failing to meet the fluctuation range standard. If the fluctuation range is within 1% and lasts for more than 30 minutes, the area is marked as having load stability characteristics and is therefore identified as a manageable area. For example, if the actual monitored average peak value of area A is 2280 A / s, the fluctuation range is within 20 A / s, and it remains stable for 45 minutes, then area A is confirmed as a manageable area. After identifying manageable areas, the controllability interface and predictable start-up load trend of the area are further marked. The controllability interface refers to the fact that the control module of the lighting fixtures in the area supports remote command transmission and status feedback. For example, the DALI (Digital Addressable Interface) of area A... The (address lighting interface) gateway can receive and execute start / stop commands and upload real-time status and current data of the lamps. Predictable start-up load trend refers to the obvious regularity of historical start-up load data in the area. For example, by performing time series analysis on the data of the past 30 days in area A, it was found that the peak start-up load in the evening is within the same date and time period of each week, with a peak value deviation of no more than 2% and a start-up duration fluctuation of less than 5 minutes. This indicates that its start-up load trend is highly predictable. Information on areas with load stability characteristics, controllable interfaces, and predictable start-up load trends, such as area A, whose controllable interface is the DALI protocol and whose predictable start-up load trend deviation is less than 2%, is compiled into a lamp start-up load stable area table.

[0060] Please see Figure 3 The specific steps to obtain the list of priority lighting fixtures are as follows:

[0061] S211: Call the table of stable load areas for lamp startup, extract the corresponding area number, time interval and original response delay, identify the area number to match each data item, and establish a set of area startup parameters;

[0062] The table of stable load zones for luminaire startup is accessed to obtain detailed information about the zones. This table records zones with stable load characteristics, controllable interfaces, and predictable startup load trends. For example, zone A, numbered "R001," has a stable time window of [18:00, 18:45], a controllable interface using the DALI protocol, and a predictable startup load trend deviation of less than 2%. The table also includes the raw response delay obtained through historical startup log analysis. The raw response delay refers to the time interval between sending the startup command and the actual startup of the luminaire. This delay data is obtained by averaging the differences between the command issuance time and the start time of the luminaire current change in historical records. For example, by analyzing the historical start-up records of lighting fixtures in area A, the average original response delay is calculated to be 500 milliseconds. Each area number is identified and matched with the data in the table. For example, for area R001, its number "R001", time interval [18:00, 18:45], and original response delay of 500 milliseconds are extracted. The extracted information is used as the area number as the primary key to create a series of data entries, for example, {area number: "R001", time interval: "[18:00, 18:45]", original response delay: 500ms}. The set of data entries is used to form the area start-up parameter set.

[0063] S212: Based on the set of regional startup parameters, sort the original response delays in ascending order, filter the regional sequence of response delays, and obtain the startup response sorting list;

[0064] Based on the set of regional activation parameters, which includes multiple regional numbers, time intervals, and original response delays (e.g., region R001 (500ms), region R002 (300ms), and region R003 (800ms), the regions are sorted in ascending order of their original response delays. This sorting is based on the order of the original response delay values ​​from smallest to largest. For example, after sorting the above regions, we get R002 (300ms), R001 (500ms), and R003 (800ms). The purpose of this sorting is to prioritize regions with faster activation response speeds in order to achieve faster response times during overall load adjustment. Through this sorting operation, a sequence of regions with response delays from smallest to largest is selected. For example, the selected region sequence is R002, R001, and R003. The delay time of each region is now clear. This sorted region sequence is then organized into an activation response sorting list. This list clearly shows the activation response priority of different regions, providing a basis for subsequent adjustments to the activation sequence of lighting fixtures.

[0065] S213: Call the startup response sorting list, compare the regional time interval with the set time interval upper limit, remove regions whose time interval exceeds the upper limit, and generate a list of lamps to be started first;

[0066] The system invokes a startup response sorting list, which contains a sequence of regions ordered by their original response delay in ascending order, along with their corresponding response delays and time intervals. For example, the first region in the list is R002, with a time interval of [18:05, 18:50] and an original response delay of 300ms; the second region is R001, with a time interval of [18:00, 18:45] and an original response delay of 500ms. The time interval for each region in the list is compared to a preset upper limit. This upper limit is set based on a comprehensive consideration of the power grid load dispatch strategy and adjustability margin. For example, through analysis of the maximum instantaneous impact load that the power grid system can withstand, combined with historical startup data, it has been verified that the upper limit of the time interval is set to 60 minutes (3600 seconds). The upper limit is designed to limit the duration of the impact on the power grid during the startup of a single area, ensuring the stable operation of the power grid. The time interval [18:05, 18:50] of area R002 is checked, and its duration is 45 minutes, which is less than 60 minutes; the time interval [18:00, 18:45] of area R001 is checked, and its duration is 45 minutes, which is less than 60 minutes. If the duration of the time interval of an area exceeds this upper limit, for example, if the time interval of R004 lasts for 70 minutes, then the area will be removed from the list. The screening process ensures that only those areas whose startup time window is within the controllable range are included in the priority startup category. The list is checked item by item, and areas that do not meet the time interval requirements are removed. The remaining areas after screening and their information are sorted to generate a priority startup list of lighting fixtures.

[0067] Please see Figure 4 The specific steps for obtaining the regional path adaptation relationship group are as follows:

[0068] S311: Call the list of priority lighting fixtures, capture the real-time current monitoring value and voltage detection device measurement value in the candidate lighting fixture group, summarize the real-time current value and voltage value of the area, and generate the area environmental status parameters;

[0069] The system retrieves the list of priority lighting fixtures to be activated, obtaining information about the areas included in the priority activation list. For example, the list might include areas R001 and R002. Area R001 covers a group of lighting fixtures on Nanjing Road, while area R002 covers a group of lighting fixtures on Chongqing Road. Real-time current monitoring and voltage detection devices deployed within the candidate lighting fixture groups synchronously capture the real-time current monitoring values ​​and voltage measurement values ​​of the lighting fixture group circuits. Current monitoring values ​​are collected at a frequency of 100 milliseconds using devices such as Hall effect sensors, and voltage measurement values ​​are collected at the same frequency using voltage transformers. For example, at a specific monitoring moment, the real-time current monitoring value of the lighting fixture group in area R001 is 25A, and the real-time voltage measurement value is 220V, while the value of the lighting fixture group in area R002 is... The real-time current monitoring value of the lamp group is 30A, and the real-time voltage measurement value is 218V. The real-time current and voltage values ​​of all monitored lamp groups in the same area are summarized. If there are multiple independent lamp group circuits in an area, the average or sum of all circuits is taken. For example, if area R001 contains two lamp group circuits, the first circuit has a current of 15A and a voltage of 220V, and the second circuit has a current of 10A and a voltage of 220V, then the summarized real-time current value of area R001 is 25A and the real-time voltage value is 220V. The summarized data, such as 25A and 220V for area R001, are used to generate the area environmental status parameter, which reflects the current power load and power supply quality of the area.

[0070] S312: Based on the regional environmental status parameters, and by comparing the current value, voltage value and the safe reference value range, select areas that meet the environmental restoration conditions to obtain a set of usable areas for environmental control;

[0071] Based on the regional environmental status parameters, which include the aggregated real-time current and voltage values ​​for each region, for example, the real-time current value for region R001 is 25A and the real-time voltage value is 220V; the real-time current value for region R002 is 30A and the real-time voltage value is 218V. The current and voltage values ​​are compared according to a preset safety reference range. The safety reference range is determined based on the State Grid operation specifications, the safe operating range of lighting equipment, and historical data analysis. For example, experimental verification shows that the most stable and safe operation occurs when the grid voltage is maintained between 210V and 235V and the regional current does not exceed 80% of the rated maximum current. Therefore, the voltage safety reference range is set to [210V, 235V], and the current safety reference range is set to [0A, 80A] (assuming the rated maximum current for this region is 10A). If 0A is the current value and 80% is the voltage value, then the environmental status parameters of each region are evaluated to determine whether the current and voltage values ​​are within their corresponding safe reference value ranges. For example, for region R001, the real-time current value of 25A is within the range of [0A, 80A], and the real-time voltage value of 220V is within the range of [210V, 235V]. Therefore, region R001 meets the environmental recovery conditions. For region R002, the real-time current value of 30A is within the range of [0A, 80A], and the real-time voltage value of 218V is within the range of [210V, 235V]. Therefore, region R002 also meets the environmental recovery conditions. Through this comparison process, all regions that meet the environmental recovery conditions are selected and the regions are aggregated into a set of environmental control available regions. This set represents a list of regions that can currently be started up with minimal impact on the power grid.

[0072] S313: Invoke the available environmental control area set, map the area number and connection channel according to the physical connection path between the listed areas and the lighting groups, using the formula:

[0073]

[0074] Calculate the adaptation value of the regional path to obtain the regional path adaptation relationship group;

[0075] Where M represents the adaptation value of the regional path, u represents the number of connection channels under the a-th regional path, and L aj This represents the physical path length of the j-th connecting channel in the a-th region path. E represents the average physical path length of all connecting channels under the path of region a. aj The physical path equivalent length coefficient represents the j-th connecting channel in the a-th region path;

[0076] The available environmental control area set is invoked to obtain a list of areas that meet the environmental restoration conditions, such as areas R001 and R002. Based on the physical connection paths between the listed areas and the lighting fixture groups, each area number is mapped to its specific connection channel in the power grid. The connection channel refers to the power transmission path from the substation to the lighting fixtures, including components such as cables, switches, and distribution boxes. For example, the lighting fixtures in area R001 are connected to sub-channel C1 of feeder L1, with a physical path length L1_C1 of 500 meters. The lighting fixtures in area R002 are connected to sub-channel C2 of feeder L2, with a physical path length L2_C2 of 600 meters. Considering the impact of different cable materials, cross-sectional areas, and laying methods on signal transmission and power loss, an equivalent physical path length factor E is introduced. aj This coefficient is obtained through experimental measurements and calculations of the resistance, reactance, and transmission loss of different types of cables in actual laying environments. For example, E for copper core cables... aj =1.0, Aluminum core cable E aj =1.2, overhead line

[0077] E aj =0.9, in a certain area path, L aj This represents the physical path length of the j-th connecting channel in the region. For example, region R001 contains two connecting channels: channel 1 has a physical length of 500 meters, and channel 2 has a physical length of 450 meters. This represents the average physical path length of all connecting channels under the path in this region. For example, the average length of region R001 is (500+450) / 2 = 475 meters. u represents the number of connecting channels under the path in the a-th region. For example, region R001 has 2 connecting channels. aj E represents the physical path equivalent length coefficient of the j-th connecting channel in the a-th region path. For example, if channel 1 in region R001 is a copper core cable, E a1 =1.0, Channel 2 is an aluminum core cable, E a2 =1.2, using the formula The adaptation value of the regional path is calculated by multiplying the deviation between the physical path length of each connection channel and the average physical path length of the regional path by the corresponding equivalent length factor. This comprehensively quantifies the complexity and electrical characteristics of the physical path. E represents the degree of deviation of a single channel length from the average length. aj We weight these values ​​to obtain the overall fit value for the entire regional path. Example calculation: For region R001, its connection channel information is as follows:

[0078] Channel 1 (L) a1 =500m, E a1 =1.0);

[0079] Channel 2 (L) a2 =450m, E a2 =1.2);

[0080] Average channel length

[0081] The fitness value of region R001 is: M R001 =|500-475|×1.0+|450-475|×1.2=55;

[0082] The calculation results show that the path fit value of region R001 is 55. A lower M value indicates that the physical length distribution of the connecting channels in the region is relatively uniform and the equivalent length coefficient is low, which means that the path structure is more regular and the electrical loss and signal transmission delay are relatively small. This fit value is calculated for each region that meets the conditions. The calculated regional path fit values ​​are organized into regional path fit relationship groups in the form of regional number and fit value pairs.

[0084] Connection Channel Physical path length (m) Physical path equivalent length coefficient Channel 1 500 1.0 Channel 2 450 1.2

[0085] As shown in Table 1, region R001 contains two connection channels. The physical path length and equivalent length coefficient of each channel are listed. These parameters are used to calculate the fit value.

[0086] Please see Figure 5 The specific steps for obtaining the lighting fixture pre-configuration start-up sequence control instruction set are as follows:

[0087] S411: Based on the regional path adaptation relationship group, collect the real-time current value of the path in the current cycle, match the safety target current corresponding to each path, merge the current value and the target value according to the path number, and generate the path current offset data group.

[0088] Based on the regional path adaptation relationship group, the path adaptation value and corresponding path number of each region are obtained. For example, the path adaptation value of region R001 is 55, and the path adaptation value of region R002 is 60. Real-time current values ​​for each path within the current cycle are collected by real-time monitoring equipment. These current values ​​are obtained through current transformers installed on the feeders of each path, with a collection frequency of once per second. For example, within the current cycle, the real-time current value of path R001 is 20A, and the real-time current value of path R002 is 28A. Simultaneously, according to the preset safe operation strategy and power grid load dispatch plan, a corresponding safe target current is matched for each path. The setting of the safe target current is based on a comprehensive determination of feeder carrying capacity, historical load curves, and instantaneous load fluctuation margin. For example, by monitoring the regional... The historical maximum safe current of the feeder located in area R001 was analyzed and verified through simulation. Its safe target current was set to 30A. For the feeder located in area R002, its safe target current was set to 35A. The target current values ​​are intended to ensure that the path can still operate stably under the impact of starting load. The current real-time current value and the corresponding safe target current are merged according to the path number. For example, for path R001, its current current value is 20A and the target current value is 30A; for path R002, its current current value is 28A and the target current value is 35A. The merged data, such as {path number: "R001", real-time current: 20A, target current: 30A}, is used to generate a path current offset data group. This data group intuitively reflects the deviation of each path current from its safe target value.

[0089] S412: Call the path current offset data group, determine the deviation direction between the current current value of each path and the safety target current, and classify the status as exceeding the standard or meeting the standard according to the sign of the deviation value, and obtain the current deviation direction identifier set;

[0090] The path current offset data set is invoked. This data set contains the path number, real-time current value, and corresponding safe target current value for each path. For example, path R001 (real-time current 20A, target current 30A), path R002 (real-time current 28A, target current 35A). For each path in the data set, the deviation direction between its current current value and the safe target current is calculated. The deviation direction is obtained by subtracting the safe target current value from the real-time current value. For example, for path R001, the deviation value is 20A - 30A = -10A, and for path R002, the deviation value is 28A - 35A = -7A. The status of a path is distinguished by the sign of the deviation value. When the deviation value is negative, it indicates that the current is lower than the target current, and the path is in a compliant state or has a margin. When the deviation value is positive, it indicates that the current is higher than the target current, and the path is in an over-standard state. For example, the deviation value of path R001 is -10A, which is judged as compliant; the deviation value of path R002 is -7A, which is judged as compliant. Through this judgment process, each path is assigned a current deviation direction identifier, such as compliant or over-standard. The identifiers are collected into a current deviation direction identifier set, which clearly indicates the real-time health status of each path in terms of current load.

[0091] S413: Based on the current deviation direction identifier set, locate the corresponding path-connected list area, adjust the starting sequence level of the area lights in the current cycle, using the formula:

[0092]

[0093] Calculate the adjustment coefficient for the start-up sequence of regional lighting fixtures within the current cycle to obtain the set of control instructions for the pre-allocation of lighting fixture start-up sequence;

[0094] Where Q represents the adjustment coefficient for the start-up sequence of regional lighting fixtures in the current cycle, and P... i P represents the starting power value of the i-th lamp in the current cycle. avg This represents the average starting power of all lamps in the current period, in W. i S represents the priority weight factor of the i-th lamp in the current cycle. i represents the start-up delay time value of the i-th lamp in the current cycle, K represents the start-up delay time correction constant, R represents the dimensionless correction value associated with the regional environmental conditions in the current cycle, and n represents the total number of lamps participating in the adjustment in the current cycle.

[0095] Based on the current deviation direction identifier set, which contains the number of each path and its current deviation direction (e.g., path R001 (compliant), path R002 (compliant), the list areas connected to the paths are located. For example, path R001 connects to the luminaires in area R001, and path R002 connects to the luminaires in area R002. According to the current deviation direction of the path, the start-up sequence level of the corresponding area luminaires in the current cycle is adjusted. The start-up sequence level adjustment aims to prioritize the start-up of luminaires in areas where the current is compliant, and to delay or downgrade the start-up of luminaires in areas exceeding the standard. The specific adjustment is achieved by calculating an adjustment coefficient Q, where Q represents the area luminaire start-up sequence level adjustment coefficient in the current cycle, and P... i This represents the starting power value of the i-th lamp in the current cycle. This power value is obtained from the rated power of the lamp. For example, if the rated power of a lamp is 150W, P abg This represents the average starting power of all lights within the current period. For example, if there are 100 150W lights in the area, the average power is 150W. i This represents the priority weighting factor of the i-th luminaire in the current cycle. This weighting factor is determined based on the luminaire's importance, the priority of its location within the area, and its historical operational stability, and its value ranges from [0.5, 1.5]. For example, the weighting factor for luminaires on main roads is set to 1.2, and for secondary roads it is 0.8. i represents the start-up delay time value of the i-th lamp in the current cycle. This value is obtained by averaging historical data. For example, the start-up delay of a lamp is 0.3 seconds. K represents the start-up delay time correction constant, which is used to compensate for measurement errors and response uncertainties. Through multiple experiments, it is set to 0.1 seconds. R represents the dimensionless correction value associated with the regional environmental conditions of the current cycle. This correction value is determined based on factors such as real-time regional meteorological conditions (e.g., light intensity, temperature) and traffic flow. Its value range is [0, 0.2]. For example, R is 0.1 when the light intensity is below 50 lux, and an additional 0.05 is added during peak traffic periods. n represents the total number of lamps participating in the adjustment in the current cycle, using the formula... The adjustment coefficient for the starting sequence of regional lamps in the current cycle is calculated. This formula calculates the absolute deviation between the power of a single lamp and the average power, multiplies it by its priority weight factor, and then sums the results. This reflects the importance of the power deviation to the adjustment. The denominator calculates the square root of the sum of the starting delay time of each lamp and the correction constant. This represents the nonlinear effect of the delay time on the overall adjustment. This is then added to the dimensionless correction value R to comprehensively consider the additional impact of environmental factors on the adjustment, thus obtaining a comprehensive adjustment coefficient.

[0096] The advantage of this formula lies in its ability to more precisely identify lamps with a greater impact on the power grid by incorporating the deviation between the starting power value and the average power value of each lamp, combined with a priority weighting factor. This allows for weighted adjustments to these lamps. Furthermore, by considering starting delay time, correction constants, and environmental correction values, the adjustment coefficients comprehensively reflect the lamp's electrical characteristics, response time lag, and the influence of the external environment. This results in a more accurate and reasonable adjustment of the lamp starting sequence. For example, taking region R001 as an example, assuming there are 3 lamps in this region (for simplified calculation), the parameters are as follows:

[0097] Table 2: Examples of Lighting Fixture Start-up Parameters

[0098] Lighting fixtures (i) <![CDATA[P i (W)]]> <![CDATA[W i ]]> <![CDATA[S i (s)]]> 1 150 1.0 0.2 2 150 1.2 0.3 3 150 0.8 0.25

[0099] Assuming K = 0.1s and environmental correction value R = 0.05, the average starting power P in this region... avg = (150 + 150 + 150) / 3 = 150W;

[0100] Molecular calculations: Lamp 1: |150-150|×1.0=0×1.0=0; Lamp 2:

[0101] |150-150|×1.2=0×1.2=0;Light fixture 3: |150-150|×0.8=0×0.8=0;

[0102] Therefore, molecules

[0103] Calculation of the denominator: Lamp 1: S1 + K = 0.2 + 0.1 = 0.3; Lamp 2: S2 + K = 0.3 + 0.1 = 0.4; Lamp 3: S3 + K = 0.25 + 0.1 = 0.35;

[0104] Therefore, the denominator

[0105] Calculate the Q value:

[0106] The results indicate that when the luminaire power is consistent and the deviation from the average value is small, the adjustment coefficient is mainly affected by the start-up delay and environmental factors. In this example, the calculated regional luminaire start-up sequence level adjustment coefficient Q is 0.05. This coefficient is directly used for subsequent start-up sequence level adjustments. For example, the start-up priority of the region can be multiplied by (1-Q) to reduce its priority, or divided by (1+Q) to reduce its priority. The calculated adjustment coefficient is used as part of the luminaire pre-configuration start-up sequence control instruction set to guide the intelligent start-up of the luminaires.

[0107] Please see Figure 6The specific steps for the batch startup path and synchronization recovery table for lighting fixtures are as follows:

[0108] S511: Call the lighting fixture pre-configuration start-up sequence control instruction set, extract the path delay changes at key time points based on the path delay data in the recovery sequence, identify the path delay fluctuation characteristics, and perform correlation analysis with the current regulation signal fluctuation rate to obtain the path delay fluctuation correlation coefficient.

[0109] The system invokes the pre-configured lighting start-up sequence control instruction set, which includes adjustment coefficients for the lighting start-up sequence level in each area. For example, the adjustment coefficient Q for area R001 is 0.05. Based on the path delay data in the recovery sequence, which originates from sensors along the power grid path, the system records the transmission delay and arrival time of the power signal at different key time points (e.g., command issuance, switch action, current rise start point). For example, the system detects that the average delay from command issuance to lighting start-up for path R001 is 100ms. At a specific key time point, such as 50ms after the start command is issued, the system extracts the path delay change. For example, it compares the current delay of path R001 with the historical average delay. If the current delay is 110ms, the delay change is 10ms, thus identifying path delay fluctuation characteristics. For example, path R... The path delay fluctuations of 001 over three consecutive cycles were 10ms, -5ms, and 8ms, respectively, showing a certain degree of volatility. Simultaneously, the fluctuation rate of the current regulation signal was acquired. The current regulation signal fluctuation rate refers to the rate at which the power grid responds to load changes. For example, by monitoring the rate of change of the output current of the main transformer in a substation, if the current changes by 50A within one second, the fluctuation rate is 50A / s. A correlation analysis was performed between the path delay fluctuation characteristics and the current regulation signal fluctuation rate to determine whether the current regulation signal fluctuation rate also increases when the path delay fluctuation is large. This correlation analysis quantifies the relationship by calculating the correlation coefficient between the path delay fluctuation and the current regulation signal fluctuation rate. For example, if they show a positive correlation, the correlation coefficient is 0.8, indicating that the greater the delay fluctuation, the more difficult the current regulation becomes. The calculated correlation degree is used as the path delay fluctuation correlation coefficient.

[0110] S512: Based on the path delay fluctuation correlation coefficient and combined with the path characteristic parameters, perform a matching judgment operation on the path's performance at key time points, filter the set of paths that meet the synchronization conditions, and obtain the synchronization path judgment value range.

[0111] Based on the path delay fluctuation correlation coefficient, which quantifies the correlation between path delay fluctuation and current regulation signal fluctuation rate, for example, the correlation coefficient for path R001 is 0.8, and the correlation coefficient for path R002 is 0.75. Combined with path characteristic parameters, including feeder impedance, capacitive reactance, cable type, length, and the total power of connected lighting fixtures, for example, the total feeder impedance of path R001 is 0.5Ω, the cable type is copper core, and the total power of connected lighting fixtures is 30kW. For the path's performance at critical time points, such as voltage drop amplitude and current rise rate during transient startup, a matching judgment operation is performed. This matching judgment operation is based on a preset synchronization condition threshold, which is determined according to the requirements of stable grid operation and the impact limit that the equipment can withstand. For example, through experimental verification, when the voltage drop amplitude... When the voltage drop is less than 5% and the current rise rate is less than 100A / s, the paths can achieve synchronization. Therefore, the voltage drop threshold is set to 5%, and the current rise rate threshold is set to 100A / s. The parameters and real-time performance of each path are judged to meet the synchronization conditions. For example, path R001 has a voltage drop of 3% and a current rise rate of 80A / s at the moment of startup, both of which meet the synchronization conditions. Path R002 has a voltage drop of 6% and a current rise rate of 90A / s, but the voltage drop does not meet the synchronization conditions. Through this matching and judgment process, all paths that meet the synchronization conditions are selected. For example, after selection, only path R001 meets the synchronization conditions. The set of paths that meet the synchronization conditions, such as path R001, whose key performance parameters are all within the threshold range, are organized to obtain the synchronization path judgment value range. This range identifies the power paths that can be used for batch synchronous startup of lamps.

[0112] S513: Call the synchronization path judgment value range, compare it with the synchronization area parameters in the current regulation signal, determine the optimal path and corresponding area parameters for batch starting of lamps, and output the batch starting path and synchronization recovery table of lamps.

[0113] The above-mentioned synchronization path determination value range is invoked. This range identifies power paths that meet the synchronization conditions. For example, this range includes path R001. This synchronization path determination value range is compared with the synchronization zone parameters in the current regulation signal. The synchronization zone parameters refer to the areas dynamically delineated by the power grid dispatch center based on factors such as the current load situation, reserve capacity, and power flow distribution, which allow for large load changes simultaneously. For example, during periods of low load, the power grid may designate certain areas as synchronization zones to allow more loads to start simultaneously, thereby optimizing power grid operating efficiency. This parameter is usually provided in real time by the power grid management and includes the number of the synchronization zone, the maximum allowed load increment, and the duration. For example, the power grid dispatch system may instruct the Grid_Zone_01 area to allow a maximum load increase of 10MW within 10 minutes. The area to which path R001 belongs, for example, if area R001 is located within Grid_Zone_01, is checked against the synchronization zone parameters. For example, checking path R001... If the potential starting load of path R001 (e.g., 30kW) is within the maximum allowable load increment of Grid_Zone_01 (e.g., 10MW), and if path R001 is located in Grid_Zone_01 and its expected starting load is much less than 10MW, then R001 is determined as the optimal path. Through this comparison process, the optimal path and corresponding area parameters for the phased starting of lighting fixtures are determined. The optimal path refers to those paths that satisfy their own synchronization conditions and match the synchronization area parameters of the power grid. The corresponding area parameters refer to the area number, time interval, and original response delay information covered by the optimal path. For example, if path R001 is finally determined as the optimal path, its corresponding area parameter is R001 (18:00-18:45, 500ms). The determined information, such as path R001 and its corresponding area parameters, is output to form a table of phased starting paths and synchronization recovery for lighting fixtures. This table provides grid dispatchers and lighting fixture control with accurate phased starting and load recovery strategies.
