基于GO法的地铁供变电系统可靠性分析
Reliability Analysis of Metro Power Supply and Transformation System Based on GO Method
摘要
Abstract
The power supply and transformation system plays a crucial role in providing power for metros.Its failure may reduce the operation efficiency of the metro and cause economic losses,or lead to major catastrophic accidents,endangering the lives of metro passengers.With the advancement in reliability technologies,applying these technologies to the metro power supply and transformation system can significantly improve the system's reliability.To ensure the long-term stable operation of the metro power supply and transformation system,this study incorporated the GO method into its reliability analysis for the first time and proposed a GO-based reliability analysis method.Firstly,the system structure was analyzed by dividing the metro power supply and transformation system into three subsystems:the main substation,the ring network cables,and the traction/step-down substations,gaining insights into their composition and working principles.Next,aiming at successful power supply,GO diagram models of corresponding subsystems were established for the main substation,ring network cables,and traction/step-down substations.A program was developed based on the calculation principles of the GO method.Then,based on the overall wiring diagram of the metro power supply and transformation system,the reliability connection ports of each subsystem were identified,and their reliability data were calculated in sequence.The data were then transferred to the next subsystem via the connection ports.Finally,the reliability data of metro power supply to the contact lines and low-voltage distribution system at different locations in the metro power supply system were obtained,providing reliability data support for future system design optimization.The GO method calculation identifies weak links in the system,providing references for operation and maintenance decision-making.关键词
