Embodiment Construction

[0055] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0056] Such as figure 1 As shown, the construction method of distribution line risk assessment model includes the following steps:

[0057] Step 1. According to the characteristic quantity of the service time dimension of the distribution line, the model factors of the service time dimension of the distribution line are obtained, and the service time dimension model is constructed.

[0058] The characteristic quantity of service time dimension includes the loss percentage of the wire tensile strength under the condition of complete annealing of the distribution line, the wire temperature, the related constants of the conductor material properties, and the continuous running time of the wire und...

Abstract

The invention discloses a distribution line risk assessment model construction method and a risk assessment method and system, and the method comprises the steps: constructing a service time dimensionmodel according to the service time dimension characteristic quantity, constructing an environment climate dimension model according to the environment climate dimension characteristic quantity, constructing a monitoring data dimension model according to the monitoring data dimension characteristic quantity, and finally, according to the service time dimension model, the environmental climate dimension model and the monitoring data dimension model, constructing a distribution line risk assessment model based on multi-dimensional feature fusion. Compared with an existing single-dimensional model, the model comprehensively considers multi-dimensional factors having important influence on the risk state of the distribution line, and the risk state of the distribution line can be reflected more scientifically and accurately; according to the risk assessment method and system, automatic assessment of the distribution line risk and active prevention and control of the risk are achieved, andthe risk assessment method and system have important significance for prolonging the service life of the distribution line, reducing the potential risk of power distribution network operation and guaranteeing the safety and stability of the distribution system.

Description

technical field [0001] The invention relates to a method for constructing a distribution line risk assessment model, a risk assessment method and a system, and belongs to the technical field of distribution automation and operation and maintenance. Background technique [0002] The purpose of distribution network risk assessment is to provide a number of quantitative risk indicators that comprehensively reflect the operation status of distribution network and the consequences of accidents in multiple time and space dimensions. As an important part of the distribution network, the outage of distribution lines is one of the root causes of system accidents. Therefore, how to fully consider various risk factors, and then accurately evaluate the reliability level of distribution lines is the core issue of evaluating the risk of distribution network. Existing risk assessment methods for distribution lines are mainly based on regression models, Bayesian models, etc., and only use ...
