Embodiment Construction

[0035] The calculation method of the risk value and risk level in the condition-based maintenance of power distribution equipment provided by the present invention will be described in detail below through specific embodiments.

[0036] The calculation method of the risk value and risk level in the condition-based maintenance of power distribution equipment provided by the present invention includes the following steps executed in order:

[0037] Step 1) Calculate the loss value of each element, the elements included are asset loss degree, cost loss degree, environmental loss degree, personal safety loss degree and household number loss degree during power outage;

[0038] Step 2) calculating the loss probability of each element;

[0039] Step 3) calculating the degree of asset loss;

[0040] Step 4) Using a weighting method to calculate the risk value and risk level of the equipment.

[0041] In step 1), in calculating the loss value of each element, the element loss is fir...

Abstract

The invention discloses a method for calculating a risk value and a risk level in state maintenance of power distribution equipment. The method comprises the following steps: 1, calculating an elementloss value of the power distribution equipment; 2, calculating the element loss probability of the power distribution equipment; 3, calculating the asset loss degree of the power distribution equipment; and 4, calculating a risk value and a risk level of the power distribution equipment by using a weighting method; the technical problems that in the prior art, no scientific evaluation method exists for the risk in state maintenance of the power distribution equipment, and the equipment operation reliability and safety are reduced are solved.

Description

technical field [0001] The invention belongs to the field of state evaluation of power distribution equipment, in particular to a method for calculating risk values ​​and risk levels in state maintenance of power distribution equipment. Background technique [0002] With the increasing scale of the distribution network, the number of distribution equipment is increasing rapidly, and the operation and maintenance tasks are increasing. Formulating a reasonable operation and maintenance strategy will help reduce the failure rate of equipment and improve the reliability of the distribution network. Reduce operation and maintenance costs. Condition evaluation and risk assessment are the basis for formulating operation and maintenance strategies, but the current risk assessment methods do not have a set of scientific assessment methods for the risks in the condition-based maintenance of power distribution equipment, which reduces the reliability and safety of equipment operation. ...
