摘要
牵引变压器是牵引供电系统的关键组分,其运行状态的健康与否直接决定电气化铁路牵引供电网络的安全可靠性、供电质量和经济效益;同时影响着电力系统的电能质量。基于此,从安全保护、在线监测与故障诊断、经济运行与调控等方面对我国牵引变压器的研发、应用现状及存在的问题进行了综合性的阐述和分析;并指出:深入研究牵引负荷特性与潮流分布,优化运行方式、合理进行保护配置和容量选择,积极探索同相供电策略的可行实施方法,构建智能化监控网络支持下的坚强型牵引供电系统,能够有力促进牵引变压器的安全经济运行,是电气化铁路牵引供电技术的主要发展方向。
Traction transformer was the key part of the traction power supply system, which running states whether healthy or not would determine the security and reliability, the power quality and economic efficiency of traction power supply, simultaneously affected the power quality of the power system. Then, comprehensive exposition and analysis was given, including our research and development, application status and existing problems of the traction transformer, which from security and protection, online monitoring and fault diagnosis, economic operation and control, etc. Finally, a major development direction of electrified railway traction power supply technology was given that studying the traction load characteristics and power flow distribution thoroughly, optimizing the operation mode,protection configuration and capacity legitimately selecting, exploring the possible implementation methods of co-phase traction power supply strategy, and building a strong traction power supply systems supported by intelligent monitoring network. It could be used to promote safe and economical operation of traction transformer effectively.
