Detailed Description
In order to better understand the technical content of the present invention, specific embodiments are described below with reference to the accompanying drawings.
Detailed description of the preferred embodiment
With reference to fig. 1, the present invention provides a power distribution system suitable for scenic spots, which is characterized in that the power distribution system comprises distribution boxes, maintenance stations, passenger flow collection devices, and a management computer arranged in a monitoring center.
The management computer is respectively connected with the distribution boxes, the maintenance station and the passenger flow collection device, and the maintenance station and the distribution boxes have corresponding relations.
The distribution box is internally provided with a monitoring device used for monitoring real-time power parameters of each power facility connected to the distribution box and sending the real-time power parameters to the management computer according to a set detection period; and the management computer receives and analyzes the real-time power parameters, generates fault information aiming at the distribution box if abnormal power parameters occur, and sends the fault information to the corresponding maintenance station.
The passenger flow acquisition device is used for acquiring passenger flow information entering a scenic spot and sending the acquired passenger flow information to the management computer, and the management computer receives and counts the passenger flow information entering the scenic spot and leads the passenger flow information into the facility operation estimation model.
The facility operation prediction model comprises a passenger flow processing module and an operation prediction module, wherein the passenger flow processing module is used for processing the collected passenger flow information by combining with the user group characteristics corresponding to each electric power facility, calculating the use probability, the use frequency and the use time period of each electric power facility, and importing the calculation result into the operation prediction module, and the operation prediction module is used for adjusting the detection strategy of each distribution box by combining with the use probability, the use frequency and the use time period of each electric power facility and the inherent characteristics of each electric power facility.
The monitoring device has two realization modes:
in the first mode, a monitoring module is additionally connected to a connecting line of each power facility in the distribution box, collected data of each monitoring module is collected and sent to the management computer, the purpose that each power facility is independently monitored without interference is achieved, and when one power facility or one monitoring module breaks down, the monitoring functions of other power facilities are not influenced. The mode is more suitable for the electric power facilities with higher risk level and needing strict real-time monitoring.
In the second mode, one or more monitoring modules are arranged in the distribution box, each monitoring module corresponds to a plurality of power facilities, power data on each power facility are collected in a polling mode, and the collected power data are sent to the management computer in real time or periodically according to a preset sending strategy. The mode is suitable for electric power facilities with lower risk level and can meet the monitoring requirement by timing monitoring.
In practical application, the two monitoring devices can be mixed, and for the electric facilities with higher risk level in the distribution box, the monitoring modules are configured independently, and for the electric facilities with lower risk level in the distribution box, one or more monitoring modules are configured in a one-to-many mode, so that the cost expenditure and the data acquisition amount are reduced.
The passenger flow acquisition device comprises ticket selling equipment arranged at a general entrance of a scenic spot, ticket checking equipment arranged at entrances of scenic spots, or shooting devices arranged at all parts of the scenic spot, acquires images of people passing through, analyzes passenger flow information on the acquired images by combining with the existing image analysis software, and even can acquire corresponding passenger flow information and the like by combining with a communication base station and through mobile phone signals in a matching range.
The use states of the electric power facilities corresponding to different passenger flow information are different, and the use states of the electric power facilities and the inherent characteristics of the electric power facilities directly influence the corresponding monitoring requirements. For example, electrical facilities in use, particularly electrical facilities with high frequency of use, will certainly need to be monitored more closely. Based on the characteristic, the invention provides the passenger flow information which is combined with real-time acquisition, and the monitoring strategy of each distribution box is adjusted in real time, so that the optimization of monitoring data is realized, the invalid data acquisition ratio is reduced, the operation efficiency of the whole distribution system is optimized, and the fault recognition rate and the corresponding troubleshooting efficiency are improved.
As shown in fig. 1, a scenic spot is divided into an east region and a west region from a regional distribution. Because the electric power facility quantity is limited and the corresponding electric power risk grade is reasonable in distribution, set up all electric power facilities of east district respectively in first block terminal #1 and first block terminal #2, concentrate all electric power facilities of west district in first block terminal #3 and first block terminal # 4. In order to ensure the efficiency of the discharge, the first distribution boxes #1, #2 correspond to the maintenance station #01, and the first distribution boxes #3, #4 correspond to the maintenance station # 02.
Based on the configuration structure, when most tourists are concentrated in the east region and the number of tourists in the west region is small, the uploading frequency of the monitoring data of the first distribution box #1 and the first distribution box #2 can be correspondingly increased, the uploading frequency of the monitoring data of the first distribution box #3 and the first distribution box #4 can be adaptively reduced, and therefore workers can put more energy on electric facilities in the east region. Preferably, further fine tuning can be performed on the power facilities corresponding to the first distribution box #1 and the first distribution box #2, for example, when the passenger flow information shows that the tourist stays in a certain scenic spot in the east area for a long time, the scenic spot corresponds to the first distribution box #1, the monitoring device in the first distribution box #1 can be remotely controlled at the moment, and the power parameter collection frequency of the power facility corresponding to the scenic spot is increased. When the passenger flow information changes, the regulation and control can be performed by referring to the policy adjustment principle. For example, as more tourists are in the western region over time, the monitoring frequency of the first distribution box #3 and the first distribution box #4 may be increased accordingly, and so on. In addition, the mode can effectively combine the scenic spot distribution characteristics to divide the areas of the electric facilities in the scenic spots, so that the workers can quickly position the corresponding electric facilities for monitoring and management.
Based on the foregoing power distribution system suitable for scenic spots, the present invention also provides a configuration method of a power distribution system suitable for scenic spots, the configuration method including:
s1: and acquiring related information of all power facilities in the scenic spot, and estimating passenger flow information in combination with the scenic spot to evaluate the power risk level of each power facility.
Preferably, in step S1, the process of acquiring the relevant information of all the electric facilities in the scenic spot, and estimating the electric risk level of each electric facility by combining the scenic spot pre-estimated passenger flow information includes the following steps:
s11: the method comprises the steps of obtaining relevant information of all power facilities in a scenic spot, wherein the relevant information of the power facilities comprises power parameters, equipment life loss ratios, fault rates and preset working time ranges, and evaluating initial power risk levels according to the corresponding power parameters, the equipment life loss ratios and the fault rates.
S12: and estimating the scenic spot passenger flow information, and calculating according to the estimation result and the preset working time range of the electric power facilities to obtain the load information, the use frequency and the use time period corresponding to each electric power facility.
S13: and correcting the initial power risk level by combining the calculated load information, use frequency and use time period corresponding to each power facility to obtain a final power risk level.
The power risk level of a power facility is determined by two factors: (1) the service state corresponding to the passenger flow information, and (2) the inherent characteristics of the electric power facilities are evaluated by combining the two factors to obtain the final electric power risk level result.
Preferably, in some cases, the scenic spot passenger flow information can be estimated based on big data technology.
S2: establishing a distribution box and maintenance station configuration model, and taking the following conditions as optimization targets: (1) the number of distribution boxes is minimum, (2) the number of maintenance stations is minimum, (3) the electric facilities of various electric power risk levels corresponding to each distribution box are in the threshold range of the number of the facilities corresponding to each distribution box, and (4) the distance from each distribution box to the nearest maintenance station is smaller than a set distance threshold, and the optimal distribution box configuration parameters and the optimal maintenance station configuration parameters corresponding to the current scenic spot are calculated.
The distribution box configuration parameters comprise the number of distribution boxes, the installation position of each distribution box and the number of the power facility corresponding to each distribution box, and the maintenance station configuration parameters comprise the number of maintenance stations and the installation position of each maintenance station.
In some examples, in step S2, the switchbox and maintenance station configuration model is:
wherein:
AiIs the total deployment area range, Sigma A, of the electric power facility corresponding to the ith distribution boxi＝AGeneral assembly，AGeneral assemblyIs the total deployment area range of all the electric facilities in the scenic spot, A0Is the largest partDeploying a region range threshold; 1,2, …, n; m is the number of service stations and n is the number of switchgears.
Di' is a corrected path distance obtained by correcting the actual path distance from the distribution box to the maintenance station by using the power risk grade of the power facility corresponding to the distribution box,
Diis the ith distribution box to the nearest maintenance station RjJ equals 1,2, …, m, Di＝mindistance‖Ci-Rj‖，D0A distance threshold is set.
In this example, the principle of the arrangement of the distribution box and the maintenance station is as follows:
within each distribution box, the number of electrical facilities of different electrical risk levels does not exceed the corresponding number threshold, e.g., the number of electrical facilities of the highest electrical risk level does not exceed 2, the number of electrical facilities of the next highest electrical risk level does not exceed 4, the total number of electrical facilities does not exceed 15, etc. According to the invention, the monitoring device arranged in the distribution box is mainly used for collecting the power parameters of the power facilities, so that the maximum number of the power facilities with different power risk levels is limited in order to ensure the monitoring efficiency, and the situation that the monitoring device cannot monitor part of the power facilities in time is avoided. On the basis, the number of the distribution boxes is controlled to be the minimum as possible, and the monitoring cost is saved.
The total deployment area range of the electric power facilities corresponding to the distribution boxes is within the corresponding deployment area range threshold value, so that the situation that the distribution boxes and the corresponding electric power facilities are too large in deployment range and difficult to set in a subsequent maintenance station is avoided.
The reasons for the failure of the electric power facility include three aspects: the power facility itself, the power supply line at the distribution box, and the power transmission line between the power setting and the distribution box. Based on the aforementioned arrangement of the deployment area range, the present invention proposes to arrange the maintenance stations with the distance from each distribution box to the nearest maintenance station being less than a set distance threshold as a limiting condition. The maintenance station is used for providing troubleshooting service, so that the closer the maintenance station is to the distribution box, the easier it is to remove the fault, and another limitation is the number of the maintenance stations, the smaller the number of the maintenance stations is, the lower the monitoring cost is, and the maintenance station is set in combination with the two aforementioned limitations and the distribution box already configured. Preferably, the present invention further provides that, in consideration of a difference in the state of the electric power facility in each of the distribution boxes, a comparison result between a corrected path distance obtained by correcting the actual path distance from the distribution box to the maintenance station using the power risk level of the electric power facility corresponding to the distribution box and the set distance threshold is used as the determination condition.
In other examples, the method further comprises:
s3: determining an initial detection strategy of each distribution box by combining the scenic spot pre-estimated passenger flow information, and
and adjusting the detection strategy of each distribution box in real time according to the actual passenger flow information of the scenic spot.
The detection strategy includes a monitoring frequency and corresponding power parameter threshold information for each of the included electrical facilities.
For example, when the load is larger, the threshold value of the power parameter is larger, and accordingly, the monitoring frequency is higher, and the like. Preferably, the monitoring frequency in the same detection strategy may be a dynamic value, including information about the period of use of the device by the user.
In order to optimize the adjustment effect of the detection strategy and accelerate the strategy operation process, the invention also provides that the process of adjusting the detection strategy of each distribution box according to the actual passenger flow information of the scenic spot comprises the following steps:
s31: and creating a facility operation prediction model, wherein the facility operation prediction model comprises a passenger flow processing module and an operation prediction module.
S32: the method comprises the steps of collecting a plurality of historical passenger flow information and facility use relations corresponding to the historical passenger flow information, constructing a first sample data set, importing the first sample data set into a passenger flow processing module, and training and testing the passenger flow processing module.
S33: the method comprises the steps of collecting historical abnormal power parameters of all power facilities, analyzing the use probability, use frequency and use time period of each corresponding power facility when each historical abnormal power parameter occurs, calculating to obtain the abnormal probability and frequency of each power facility under different conditions and an optimal detection strategy by combining the inherent characteristics of the power facilities, generating a second sample data set, importing the second sample data set into an operation estimation module, and training and testing the operation estimation module.
S34: the method comprises the steps of collecting passenger flow information (such as the age and the sex of tourists, whether the tourists are team members or not) in real time, importing a facility operation estimation model, calculating to obtain facility information which is possibly used by all the tourists in a scenic spot at present, the use probability, the use frequency and the use time period of each facility, and outputting an optimal detection strategy of each distribution box according to the use probability, the use frequency and the use time period of each facility and the inherent characteristics of each power facility.
