Description

Method and system for analyzing tower tilting trend

technical field

The invention belongs to the field of electric power, and in particular relates to a method and a system for analyzing the tilting trend of a tower.

Background technique

The power system is an important industrial system that maintains the operation of the society. The power system includes three links: power production, power transmission and power use. The normal operation of these links will directly affect the stability of the society. Therefore, it is necessary to take reasonable monitoring measures to Make sure it works properly.

The pole tower is the support used to support the transmission line in the overhead transmission line, mostly made of steel or reinforced concrete, and is the main support structure of the overhead transmission line. However, its load-bearing function depends on the specific structure. If its structure is abnormal, its load-bearing capacity will change, posing a potential threat. Since the towers are required to undertake the power production and power use links, they are distributed in a wide range, often across provinces and cities. Therefore, it often happens that the lines and towers related to the power transmission link need to be installed in uninhabited places. Because these places are far away from people, it is inconvenient to carry out detailed inspections. Therefore, the method of measuring the tilt is generally used to analyze its working status. In order to ensure the safety and stability of the power transmission link, it is necessary to monitor the towers in the power transmission link.

In order to solve or improve the problems raised by the background, the present invention provides a method for analyzing the inclination trend of the tower as shown in Figure 1, including: S1, obtaining historical inclination data of the tower; The type, environmental parameters and remedial measures are used as input, and the inclination data is used as output to establish a prediction model; S3. Obtain the inclination trend data of the target tower through analysis of the prediction model.

The pole tower is the support used to support the transmission line in the overhead transmission line, mostly made of steel or reinforced concrete, and is the main support structure of the overhead transmission line. Sometimes towers are built in relatively rugged places, such as hillsides and mountains. These places are not convenient for manual work. Therefore, it is not easy to manually inspect each part/structure of the tower to verify its load-bearing capacity, and the efficiency is also low. Low. And in reality, there is a tower built at a certain distance, and the cost of detailed inspection of each tower is too high.

A large power system will have a large number of towers, and each tower may be installed in a different environment. As time changes, the tower is aged or an accident occurs, causing the tower to incline, and the inclination may include a change in the structural angle of the main body or part of the structure of the tower. The historical inclination data is the data of the change of the structural angle of the main body or part of the structure of a single tower obtained from the measurement/observation records. In the absence of a large-scale power system, it is possible to build a simulated tower in the laboratory and obtain historical tilt data through environmental simulation.

Set the data processing model. The specific model type is not limited. Its function is to describe the principle of the tilting result of the tower under certain conditions; specifically, the structure type, environmental parameters and remedial measures of the tower are used as input, and the tilt data is used as output. The corresponding data The processing model is a predictive model. Wherein, the structure type is used to describe the engineering structure/building structure of the tower, and the tower may include different engineering structures/building structures. The environmental parameters are used for the environment of the construction site/working site of the tower, such as the specific values such as temperature, humidity, and light corresponding to the working site, or the geographical forms such as mountain tops, valleys, and plains corresponding to the construction site. Remedial measures are used to describe maintenance measures for tilted towers/other faulty towers, such as reinforcement of a structural component, replacement of a structural component, reduction of a structural component, etc. The tilt data refers to the change of the specific engineering structure, which produces angle change data between it and the original state.

Obtain the structure type, environmental parameters and remedial measures of the target tower, and output the tilt trend data of the target tower through the prediction model. The tilt trend data includes what kind of tilt result will be produced after an approximate time.

The prediction model is based on regression analysis, and a regression equation between the structure type, the environmental parameters, the remedial measures and the tilt data is established; correspondingly, the tilt of the target tower is obtained through the analysis of the prediction model The trend data includes: outputting the tilt trend data based on the structure type, environmental parameters and remedial measures of the target tower, combined with the regression equation.

Regression analysis refers to the use of data statistics principles to mathematically process a large amount of statistical data, determine the correlation between the dependent variable and some independent variables, and establish a regression equation/function expression with good correlation for predicting future factors. Analytical methods for changes in variables.

The said based on the historical record includes: based on the historical record, determining the case with the structure type, the environmental parameter and the slope trend data; or, based on the historical record, determining the case with the structure type , the environmental parameters, the remedial measures and the cases of the inclined trend data; setting data filtering conditions to exclude specific cases from the historical records.

As a part of standardized industrial products, pole towers have relatively similar construction specifications and working environments. The state of the tower will affect the safety of the power system, so the staff of the power system hope to be able to accurately grasp its state. In order to improve the accuracy of the prediction model, the historical data can be screened to make the prediction model more specific to the target tower. Specifically, cases satisfying structural types, environmental parameters, and slope trend data are used as data sets for training prediction models. Among them, the case is a data set for a single tower, and the content of the data set includes the structure type, environmental parameters and tilt records of the tower. The principle of screening is to select a data set with a higher matching degree based on the properties of the target tower itself (mainly the structure type and environmental parameters, because the target tower generally has no problems or has minor problems. At this time, the tilted data can be added). To train the prediction model for the target tower.

The setting of data filtering conditions to exclude specific cases from the historical records includes: according to at least one of structure type restrictions, environmental parameter restrictions, remedial measures restrictions and tilt data restrictions, excluding all cases that meet the corresponding restrictions. Describe the case.

According to the structure type of the target tower, determine the structure type limit; according to the structure type and the environment of the target tower, determine the environmental parameter limit; according to the structure type and/or the target tower Or in the environment, determine the limit of the remedial measures; determine the limit of the tilt data according to a preset threshold.

In reality, the tower is an industrial product that has been designed/experimented, so the biggest factor that determines the load-bearing capacity of the tower is the structure type, and the firmness of different structure types is not the same. Structure type restrictions can be used to restrict towers to adopt the same type of structure or similar structures.

The installation environment of different towers may be very different, but the installation environment/working environment of adjacent towers may be very close. From the big aspect, the towers belong to the towers in the south; from the middle aspect, the towers belong to the towers of the same terrain; from the small aspect, the towers belong to the same temperature zone, humidity zone, light environment, etc. Because the biggest factor that determines the load-bearing capacity of the tower is the structure type, therefore, generally speaking, it is the structure type + environmental parameters that cause the tower to tilt.

There are many restrictions on remedial measures, because not all remedial measures can be widely applied to all towers, and they need to be selected according to the specific structure type and environment. For example, some tower structures are not suitable for remedial reinforcement, and some are not suitable for replacement; or some reinforcement methods require specific reinforcement materials, and the reinforcement materials are not suitable for high temperature and high humidity environments.

Tilt data is the data that intuitively shows the structural state of the tower. In many cases, it is a key indicator to determine whether the tower is normal; therefore, if the tilt is greater than the preset threshold, it means that the tower is abnormal, and the damaged tower Records do not have to be used as a training set, because the purpose of this method is prevention, so the important data is the data when the degree of inclination is less than the preset threshold.

Through specific restrictions, cases can be screened reasonably, and the prediction ability of the prediction model for specific target towers can be improved.

The present invention provides a tower inclination trend analysis system, including: a first unit 1, used to obtain historical inclination data of the tower; The measures are used as input, and the inclination data is used as output to establish a prediction model; the third unit 3 is used to analyze and obtain the inclination trend data of the target tower through the prediction model.

The said based on the historical record includes: based on the historical record, determining the case with the structure type, the environmental parameter and the slope trend data; or, based on the historical record, determining the case with the structure type , the environmental parameters, the remedial measures and the cases of the inclined trend data; setting data filtering conditions to exclude specific cases from the historical records.

Describe the case.
