Problems solved by technology

[0005] The technical problem to be solved by the present invention is that in the prior art, the fault analysis of the traction power supply system is mostly focused on the fault analysis of the catenary and the fault tree is established with the subsystem as the node. This analysis method lacks general versatility and cannot be extended to The fault analysis of the entire traction power supply system aims to provide a JavaWeb-based traction substation reliability analysis method and system to solve the above problems

Embodiment 1

[0036] The JavaWeb-based traction substation reliability analysis method of the present invention includes the following steps: S1: divide the wiring of the traction system into a bus layer, a transformer layer and a catenary layer; S2: divide the bus layer, transformer layer and catenary layer according to the wiring diagram Generate fault trees separately, and the fault trees of the bus layer, transformer layer and catenary layer are independent of each other; S3: analyze the tree nodes on the fault tree and obtain the reliability of the bus layer, transformer layer and catenary layer according to the analysis results .

[0037]During the implementation of this embodiment, the wiring of the traction system is divided into a bus layer, a transformer layer and a catenary layer, so that the present invention can be more in line with the actual situation, and the bus layer, the transformer layer and the catenary layer are respectively generated according to the wiring diagram. Fa...

Embodiment 2

[0039] In this embodiment, on the basis of Embodiment 1, step S2 includes the following sub-steps: S21: Encapsulate the component data in the traction system; S22: Convert each component in the traction system into a tree node at a corresponding position; S23 : Transform the line wiring diagram into a tree structure according to the tree nodes and generate a fault tree.

[0040] During the implementation of this embodiment, in order to realize the conversion of components into tree nodes, the present invention creatively adopts data encapsulation technology, firstly encapsulates the component data, so as to facilitate the subsequent node conversion programming, and then according to the package data, the components are equivalent to Corresponding tree nodes, so that the tree nodes constitute a fault tree, and then realize the conversion of the components in the line wiring diagram into a fault tree. The invention adopts data encapsulation to realize the generation of fault tre...

Embodiment 3

[0045] In this embodiment, on the basis of Embodiment 2, step S21 includes the following sub-steps: encapsulating the element name, failure probability, parent node name and element number of the element into a class; providing data setting and acquisition methods for the class.

[0046] When this embodiment is implemented, the encapsulation technology used in the present invention relies on classes in Java technology, and this class is used to encapsulate component data, so that data can be set and read conveniently.

[0047] The specific code and process are as follows:

Abstract

The invention discloses a reliability analysis method for a traction substation based on JavaWeb, which includes the following steps: S1: divide the wiring of the traction system into a bus layer, a transformer layer and an catenary layer; S2: divide the bus layer, transformer layer and catenary layer according to The wiring diagram generates fault trees separately, and the fault trees of the bus layer, transformer layer and catenary layer are independent of each other; S3: analyze according to the tree nodes on the fault tree and obtain the fault tree of the bus layer, transformer layer and catenary layer according to the analysis results reliability. The invention also discloses a JavaWeb-based traction substation reliability analysis system adopting the method. The present invention effectively applies the fault tree to the entire traction system by setting the above steps, and has strong versatility. At the same time, since the bus layer, the transformer layer and the catenary layer are generated as independent fault trees, the detection results are more in line with reality.

Description

technical field [0001] The invention relates to the technical field of electric power engineering, in particular to a reliability analysis method and system for traction substations based on JavaWeb. Background technique [0002] With the rapid development of the national economy and the increase of urban traffic volume, urban rail transit, as a new means of transportation, plays an increasingly important role in urban development and citizens' daily life. Once the power supply is interrupted, it will not only cause the paralysis of urban rail transit, but also endanger the safety of passengers and cause property damage. Therefore, the research on the reliability of traction power supply system is becoming more and more important. [0003] The traction power supply system has many wirings and complex component structures. When analyzing the reliability of the traction power supply system, it is necessary to find the combination of various failure modes, so that the weakness ...
