Description

Technical Field

[0001] The present invention relates to the technical field of power transmission and transformation operation and maintenance, and particularly to a method, a system, an electronic device and a medium for determining the corrosion grade of transmission line fittings. Background Art

[0002] Air pollutants near insulators are collected along the transmission corridor. Through the analysis of anion-cation pairing, it can be determined that the main soluble salt components are sulfates, chlorides, nitrates, etc. Among them, sulfates are an important cause of corrosion. Soluble sulfates in acidic wet deposition accelerate the generation of cracks in fittings, leading to the corrosion failure of fittings. Severe air pollution mostly occurs in periods with high humidity and relatively stable air. The relative humidity range in this period is 60% - 90%. There are many days of near-surface multi-layer temperature inversion and the atmosphere tends to be stable, resulting in the difficulty of pollutant diffusion. Moreover, the distribution of acid rain is mainly concentrated in high-temperature and high-humidity areas as well as basin areas. These areas have relatively serious air pollution and are characterized by highly corrosive acid-type wet deposition. The high-humidity environment induces the surface rust of transmission line fittings. Under multiple factors such as chemistry and current, corrosion fractures are likely to occur, directly causing transmission line tripping and affecting the regional power supply safety. Therefore, the problems of corrosion and wear of transmission line fittings are the focus of engineering technology attention. However, the existing classification principle for the corrosion grade of fittings is implemented according to the provisions of GB / T19292.2-2018 "Corrosion of metals and alloys - Atmospheric corrosion - Part 2: Guidance on corrosion grades", using the method of metal coupon, which cannot specifically guide the transmission line, resulting in inaccurate corrosion grades of fittings on the transmission line.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0033] As Figure 1 shown, the embodiments of the present invention provide a method for determining the corrosion grade of transmission line fittings. The general steps are as follows: S1 Dynamically obtain meteorological distribution information; the meteorological distribution information includes several parameters such as wind speed and direction, temperature, and humidity. S2 Consider the micro-topography factors of the transmission line; focus on the micro-topography factors of pollution emissions, including enclosed feature areas such as basins and canyons; consider the micro-meteorological factors of the transmission line, including micro-meteorological factors such as rain, fog, and rime. S3 Dynamically obtain pollution distribution information and pollutant census data; including aerosols, sulfur and nitrogen emissions, and dust deposition, etc., consider the pollution sources, and focus on industrial pollution sources such as metal smelting, coal-fired power generation, and cement building materials. S4 Consider the characteristics of the fitting body; including the fitting material, usage, the service life of the fitting, and the estimated failure rate. S5 Make a comprehensive analysis and evaluation of the risk and corrosion possibility of the occurrence of the corrosion environment of the transmission line fittings. As Figure 2 shown, the specific steps include:

[0034] Step 101: Obtain the grade parameter values within the target area. The grade parameter values include the information parameter values of pollutants within the set range of each transmission tower, the total number of pollutant types within the set range of each transmission tower, the evaluation value of the body parameter factors of the fitting, the corrosion failure rate of the fitting, and the parameter value set of each transmission tower; the parameter value set includes the position coordinates of the transmission tower, the position coordinates of all weather stations within the set range of the transmission tower, and the meteorological distribution information of all weather stations within the set range of the transmission tower; the information parameter values of the pollutants include: pollutant concentration, the service life of the fitting, and pollutant types; the fitting is arranged on the transmission tower.

[0035] Step 102: For any transmission tower in the target area, calculate the pollution parameter factor evaluation value within the set range of the transmission tower according to the information parameter value of the pollutants within the set range of the transmission tower and the total number of pollutant types within the set range of the transmission tower.

[0036] Step 103: Calculate the meteorological distribution information within the set range of the transmission tower according to the parameter value set of the transmission tower.

[0037] Step 104: Obtain the corrosion grade of the fittings on the transmission tower according to the evaluation value of the body parameter factors of the fittings in the target area, the corrosion failure rate of the fittings in the target area, the meteorological distribution information within the set range of the transmission tower, and the evaluation value of the pollution parameter factors within the set range of the transmission tower.

[0038] In practical applications, the determination process of the evaluation value of the body parameter factors of the fittings is as follows:

[0039] According to the formula Calculate the evaluation value S of the body parameter factors of the fittings, where A c is the c-th normalized body parameter of the fitting, and the body parameters of the fitting are the body characteristics of the fitting, including: fitting material, usage, and fitting service life, etc., n c is the number of body parameters. For a certain type of fitting, after calculation, S is a fixed value.

[0040] In practical applications, the determination process of the corrosion failure rate of the fittings is as follows:

[0041] According to the method provided by the existing literature, analyze the corrosion failure rate of the fittings with typical connection fittings. According to the formula Calculate the corrosion failure rate P of the fittings, where P f，a represents the failure rate of the a-th fitting device on the f-th transmission tower, where μ is the mean value of the corrosion life of the connection fitting; δ is the standard deviation of the corrosion life. These two values are the mean value and standard deviation of this type of failed fittings in this area; there are n l such fittings on these transmission towers, and σ takes the longest life value of these fittings. For the fittings of the same type and batch on the transmission towers in the same area, the P value can be a fixed value.

[0042] In practical applications, the calculation of the pollution parameter factor evaluation value within the set range of the transmission tower according to the information parameter value of the pollutants within the set range of the transmission tower and the total number of pollutant types within the set range of the transmission tower specifically includes:

[0043] According to the formula Calculate the pollution parameter factor evaluation value within the set range of the transmission tower, where C iRepresents the evaluation value of the pollution parameter factor within the set range of the \(i\)-th transmission tower, \(\xi\) w Represents the corrosion coefficient, which is related to the corrosion of fittings by a certain pollutant. The stronger the corrosion ability of the pollutant, the larger this value, \(E\) iw Represents the information parameter value of the \(w\)-th pollutant within the set range of the \(i\)-th transmission tower, \(n\) iw Represents the total number of pollutant types within the set range of the \(i\)-th transmission tower.

[0044] In practical applications, calculating the meteorological distribution information within the set range of the transmission tower according to the set of parameter values of the transmission tower specifically includes:

[0045] According to the formula Calculate the meteorological distribution information within the set range of the transmission tower, taking into account the micro-topography factors and meteorological information of the transmission line. Among them, \(W\) i Represents the meteorological distribution information within the set range of the \(i\)-th transmission tower, \(W\) i,j Represents the meteorological distribution information of the \(j\)-th meteorological station within the set range of the \(i\)-th transmission tower, \(n\) g Represents the total number of meteorological stations, \((X\) i , \(Y\) i , \(Z\) i ) represents the position coordinates of the \(i\)-th transmission tower, \((X\) i,j , \(Y\) i,j , \(Z\) i,j ) represents the position coordinates of the \(j\)-th meteorological station within the set range of the \(i\)-th transmission tower, \(\eta\) represents the terrain correction coefficient affected by the terrain. Among them, \(X\) i and \(X\) i,j are longitude values, \(Y\) i and \(Y\) i,j are latitude values, \(Z\) i and \(Z\) i,j are altitude values.

[0046] In practical applications, obtaining the corrosion grade of the fittings on the transmission tower according to the evaluation value of the body parameter factors of the fittings in the target area, the corrosion failure rate of the fittings in the target area, the meteorological distribution information within the set range of the transmission tower, and the evaluation value of the pollution parameter factors within the set range of the transmission tower specifically includes:

[0047] The comprehensive analysis and evaluation result \(V\) of the risk and corrosion possibility of the occurrence of the corrosion environment of the transmission line fittings based on the considered factors and data i , this evaluation can automatically obtain geological environment, climate information, and pollutant information. Specifically, according to the formula \(V\) i =f(S, P, W i , C i ) = \(\omega\) i \(\omega\) i'p i Calculate the corrosion evaluation result V of the fittings on the i-th transmission tower i , where ω i is the self-weight of the corrosion evaluation index of the i-th transmission tower and can be set by itself, ω i ′ is the mutual weight of the corrosion evaluation index of the i-th transmission tower and can be set by itself, p i is the standardized value of the corrosion evaluation index of the i-th transmission tower, and is obtained by standardizing S, P, W i and C i respectively.

[0048] Obtain the corrosion grade according to the corrosion evaluation result. Specifically, the corrosion evaluation result of the fittings can be divided into 5 levels: low (0 - 0.159), relatively low (0.159 - 0.245), medium (0.245 - 0.312), relatively high (0.312 - 0.393) and high risk (>0.393). The values in parentheses are the corrosion evaluation results.

[0049] Subsequently, a corrosion wet deposition area distribution map can be established according to the corrosion grade, and differential protection measures can be adopted through the distribution law.

[0050] The present invention also provides an embodiment of using the above method to evaluate and classify the corrosion of fittings on a 500 kV line. It is obtained that there are more areas with relatively high risks, mainly concentrated in the line corridors between towers 184 - 176, 144 - 155, 83 - 122, 46 - 74, and 27 - 31, while there are fewer areas with high risks, concentrated in the transmission corridor of section 112 - 123. The high risk accounts for about 5.98%, and the relatively high risk accounts for 48.91%. The terrain characteristics of the transmission corridor and the pollution distribution both affect the distribution of the fitting evaluation. This trend distribution reflects the overall corrosion situation of the fittings. However, for some transmission towers with high corrosion degree of the fittings, the failures caused by such fittings are relatively high. Therefore, key attention should be paid to the fittings with high danger, or the vulnerable fittings such as vibration dampers that are likely to cause harm to other equipment. The consequences caused by the corrosion of these fittings are serious. The higher the corrosion risk level of the fittings, the more sufficient the corrosion conditions in the risk area of the transmission corridor, and the greater the probability of fitting failures. These areas need to be focused on.
