Problems solved by technology

However, when studying the reliability of the main wiring of smart substations with new equipment, due to the lack of statistics on the reliability indicators of new equipment, for the reliability indicators of new equipment, the indicators that are approximately equal to those with higher reliability levels in traditional equipment are used. Represents the trend of equipment performance improvement. Obviously, this processing method is empirical and cannot objectively describe the impact of new equipment on the reliability of the main wiring design of smart substations.

Embodiment Construction

[0028] The present invention proposes a method for analyzing the reliability of the main wiring of an intelligent substation based on an uncertain random system. The present invention will be described in detail below in conjunction with the drawings and embodiments.

[0029] Such as figure 1 As shown, the reliability analysis method of the main wiring of the smart substation based on the uncertain stochastic system includes the following steps:

[0030] Step A: Transform the main wiring system of the smart substation into an uncertain random system logic diagram, and calculate the minimum path set of the system;

[0031] The formation of the minimum road set is the same as the reliability analysis method of the traditional substation main wiring, and will not be repeated here. Specifically, such as figure 2 As shown, an example of the logic diagram of an uncertain stochastic system is given, which includes a reliability of a 1 ,a 2 The random element ξ of 1 ,ξ 2 and a ...

Abstract

The invention, which belongs to the technical field of the reliability analysis for a power system, discloses an uncertain-random-system-based main wire reliability analysis method of an intelligent substation. The method comprises: a main wiring system of an intelligent substation is converted into an uncertain random system logic map, and a minimal route set of the system is calculated; according to a reliability criterion, a structure function of the uncertain random system is obtained; and a reliability degree of the uncertain random system is calculated. A case analysis demonstrates that practical intelligent substation reliability description can be provided even though the reliability index statistics deficiency occurs. The method is suitable for practical engineering application.
