Application of Fuzzy Petri Net in Fault Diagnosis of Traction Power Supply System for High-Speed Railway
摘要
Abstract
It is pointed out that in the fault diagnosis of traction power supply system for high-speed railway the uncertainty and fuzziness in the obtained action information of protective relayings and circuit breakers should be taken into account. For this reason, the fuzzy Petri net is applied in the fault diagnosis of traction power supply system. Considering the particularity of protective relayings for traction power supply system, the second reasoning is conducted. In allusion to the feature that more components are brought into the protection range of feeder remote backup protection during over-zone power supply, the reasoning conditions are increased to ensure the correctness of the reasoning. According to the fault characteristic of feeder section, a discrimination rule for fault section in feeder section is given. Results of calculation example show that the fuzzy Petri net based fault diagnosis for traction power supply system is sententious and its reasoning is intuitionistic. The proposed fault diagnosis method can improve the credibility in the discrimination of fault section while the fault information is uncertain or absent关键词
