Embodiment 1

[0038] A method for evaluating the reliability of power communication network equipment based on a capsule network, comprising steps:

[0039] The reliability evaluation of the equipment is carried out through the trained power communication network equipment reliability evaluation model;

[0040] The power communication network equipment reliability assessment model is constructed based on the capsule network and obtained through training of original data and generated disturbance data.

[0041] Further, the input of the power communication network equipment reliability evaluation model is: the text information of the operation and maintenance data; the output is: the number of possible failures of the equipment in a certain period in the future.

[0042] The model building process is:

[0043] The text information of the operation and maintenance data is processed by the word embedding method to obtain the input word vector, and the input word vector is extracted with convo...

Embodiment 2

[0065] A method for evaluating the reliability of power communication network equipment based on a capsule network, comprising steps:

[0066] Step 1. Construct a reliability evaluation model for power communication network equipment with the capsule network as the core;

[0067] The overall framework of the capsule network model adopted in the present invention is as follows: figure 1 shown. The framework is built on top of general natural language processing frameworks and adapted to the problem of device reliability assessment. The model uses text information with a unified structure as the network input, so the long-term operation and maintenance data of the power network with different structures can be directly used as the original text to input the unified neural network structure. The input signal (that is, the input of the neural network structure) can be processed by the common word embedding method to obtain the input word vector of the same dimension. Feature ex...

Abstract

The invention discloses an electric power communication network equipment reliability evaluation method based on a capsule network. The method comprises the following steps: carrying out reliability evaluation on equipment through a trained electric power communication network equipment reliability evaluation model, wherein the model construction process comprises the following steps of processingthe text information of the operation and maintenance data through a word embedding method to obtain an input word vector; carrying out feature extraction on the input word vector by using convolution filters with different sizes, combining the extracted features in a serial connection manner, and further carrying out convolution filtering on each position where the features are obtained by usingthe convolution filter to form a capsule feature vector; binding an activation value to each capsule feature vector; compressing the number of capsules, and then obtaining a new capsule feature vector and a new activation value through a capsule routing method based on kernel density estimation, wherein the new activation value is used for regression prediction; and inputting the new capsule feature vector into a decoder to reconstruct an input feature. The method can conveniently and accurately evaluate the reliability of the power communication network equipment.

Description

technical field [0001] The invention relates to the fields of equipment reliability evaluation and machine learning, in particular to a capsule network-based power communication network equipment reliability evaluation method. Background technique [0002] Modern power communication networks are rapidly increasing in size and complexity. As an important infrastructure of the modern smart grid, the power communication network not only provides various guarantee services required by the grid, but also monitors the equipment and sensors on the network in real time and maintains key operating data. Therefore, it is more and more important to evaluate and analyze the reliability of the equipment of the communication network itself. Traditional power communication network operation and maintenance usually means periodic maintenance or short-term fault alarm recovery, and automatic reliability assessment and prediction methods can further reduce the risk of serious network failure...
