Embodiment Construction

[0055] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0056] like figure 1 Shown is a work flow diagram of a reliability evaluation method for a direct current transmission system outage maintenance mode of the present invention, including:

[0057] Step S101, selecting a fault set including at least one fault;

[0058] Step S102, obtaining operation statistical parameters of the normal operation of the direct current transmission system when a fault in the fault set occurs;

[0059] Step S103, obtaining maintenance statistical parameters of the direct current transmission system using the outage maintenance mode when a fault in the fault concentration occurs;

[0060] Step S104, evaluating the reliability of the outage and maintenance mode according to the operation statistical parameters and the maintenance statistical parameters.

[0061] Among them, in step S104, after obtaining t...

Abstract

The invention relates to the relative technical field of direct current transmission system reliability evaluation, in particular to a method and a system for evaluating the reliability of a direct current transmission system shut-down and overhaul mode. The evaluation method comprises the following steps that a fault set which at least comprises one fault is selected; operation statistical parameters when faults in the fault set occur during the normal operation of a direct current transmission system are acquired; the overhaul statistical parameters of the direct current transmission system when the shutdown and overhaul method is adopted for the faults in the fault set are acquired; and the reliability of the shutdown and overhaul method is evaluated according to the operation statistical parameters and the overhaul statistical parameters. According to the method and the system for evaluating the reliability of the direct current transmission system shut-down and overhaul mode, a specific reliability indicator is worked out by comparing different statistical parameters when the direct current transmission system works normally and one shut-down and overhaul method is adopted, and the reliability of the shut-down and overhaul method of the direct current transmission system is evaluated through the indicator, so that whether the shut-down and overhaul method meets the requirements on the reliability or not is determined.

Description

technical field [0001] The invention relates to the technical field related to the reliability evaluation of a direct current transmission system, in particular to a method and a system for reliability evaluation of a direct current transmission system outage maintenance mode. Background technique [0002] At present, there is no index suitable for evaluating the reliability of the whole grid system affected by the direct current transmission system in China. The reliability indexes of the DC channel are all based on the equipment components of the DC transmission system, but there are no definite research results on the influence of the DC channel as a whole on the reliability of the system. In terms of theoretical research on the reliability of power transmission enterprises, the reliability contribution of transmission channels to the system can be obtained according to the theory of proportional distribution of reliability levels, but this theory has not yet entered the ...
