Standby type carries out structure division to the transmission facility, obtains the corresponding quantity of state of each structure.
In above-mentioned steps, transmission facility is each building block of transmission line of electricity, such as conducting wire, lightning conducter, insulator, bar
Tower, earthing or grounding means etc..Each transmission facility be made of multi-section separation structure, and the corresponding working condition of each structure is then for for transmitting electricity
The fault signature of equipment state assessment, is indicated with quantity of state.
Equipment state acquisition module 320 is set for the corresponding quantity of state of each structure to be input to preset transmission of electricity
Standby status assessment model, obtains the operating status of the transmission facility.
In above-mentioned module, transmission facility status assessment model is the model of preset assessment transmission facility operating status.It is defeated
Each quantity of state of electric equipment status assessment model synthesis input, assesses the operating status of transmission facility entirety.Wherein, it runs
State indicates the working condition of transmission facility, and the working condition of transmission facility is good, then transmission facility is in normal operating conditions；
If the working condition of transmission facility is bad, transmission facility is in abnormal operating state, thus detects transmission facility in the presence of scarce
It falls into.
Line status evaluation module 330 is used for the operating status according to the transmission facility to the transmission line status
It is evaluated.
In above-mentioned module, the operating status of each transmission facility, obtains the operation shape of transmission line of electricity in comprehensive transmission line of electricity
State whether there is failure risk to evaluate transmission line status to detect transmission line of electricity.
Above-mentioned transmission line status evaluating apparatus, is obtained by quantity of state acquisition module 310 and equipment state acquisition module 320
After taking the transmission facility in transmission line of electricity, transmission facility is divided into after multiple structures and is input to preset transmission facility state and comments
Estimate in model, obtain the operating status of transmission facility, thus by line status evaluation module 330 according to each transmission facility
Operating status evaluates the state of transmission line of electricity, is not only really comprehensively reflected the situation of transmission line of electricity, improves defeated
The efficiency of electric line state evaluation also improves the accuracy of transmission line malfunction detection.
The transmission line status evaluating apparatus further includes in one of the embodiments,：Model construction module, for obtaining
Take the fault correlation data of the transmission facility；According to the fault correlation data, the transmission facility status assessment mould is built
Type.Wherein, fault correlation data are all data associated with transmission facility failure, the original to be broken down due to transmission facility
Because being influenced by various inside and extraneous factor, therefore data associated with transmission facility failure generally comprise two aspects：One
Aspect is to indicate the data of transmission facility internal damage rule, such as equipment real-time status and operating condition directly affect transmission of electricity and set
The data of standby operation conditions；On the other hand it is the influence data etc. for indicating external environment to transmission facility, such as weather environment, geography
Condition, historical record etc. influence the data of transmission facility operation conditions indirectly.
The model construction module in one of the embodiments, the historical failure number for obtaining the transmission facility
Data are influenced according to environment；The historical failure data and the environment are influenced data to merge, generate transmission facility shape
State assesses interconnection constraint knowledge base；According to transmission facility status assessment mould described in the status assessment interconnection constraint construction of knowledge base
Type.Historical failure data is to characterize the historical data of transmission facility damage law, and environment influence data are external environment to transmission of electricity
The influence factor data of equipment.By Correlation Analysis Technology, according to the quantity of state, defect type, Defect Correlation of transmission facility
Historical failure data and environment are influenced data and merged by the incidence relation between the data such as relationship and quantity of state changing rule,
The consistent relationship between transmission facility failure and outside environmental elements can be obtained, to according to transmission facility failure and extraneous ring
Consistent relationship between the factor of border generates the interconnection constraint knowledge base of reflection transmission facility correlated condition.
The model construction module in one of the embodiments, is gone through for obtaining the environment influence data with described
The environment is influenced data and the historical failure data by the incidence relation between history fault data according to the incidence relation
It is merged.It should be noted that incidence relation characterization environment influences the correlation degree between data and historical failure data, shadow is used
It rings weight to indicate, weighing factor is big, then it represents that this kind of environment influences data and cause the possibility of transmission facility failure big, closes to be strong
Join data；Weighing factor is small, then it represents that this kind of environmental factor causes the possibility of transmission facility failure small, is weak rigidity data.
Then according to historical statistical data, determination is weighted to each strong and weak associated data, to which environment is influenced data and history
Fault data is merged.
The model construction module in one of the embodiments, for obtaining the transmission facility in the setting period
Historical failure data and environment influence data；The historical failure data and the environment are influenced data to merge, obtained
The fault signature tree of the transmission facility, and according to the fault signature tree, generate transmission facility status assessment interconnection constraint and know
Know library；According to transmission facility status assessment model described in the status assessment interconnection constraint construction of knowledge base.
In above-described embodiment, fault signature tree is for indicating the relationship between equipment fault type and failure priming factors.It is defeated
