轨道交通供电系统自愈控制架构研究

Research on Self-healing of Power Supply System for Rail-transit

随着电网的可靠性、先进性逐步提高,自愈能力已成为未来先进电网系统的核心功能。分析对比了配电网系统以及轨道交通供电系统的自愈技术研究现状和技术特点,指出了目前轨道交通供电系统自愈性的不足;通过对轨道交通供电系统的故障场景、自愈需求进行梳理,初步分析了自愈体系的实现方法,并提出了自愈系统的一种整体架构。关于轨道交通供电系统自愈功能实现的约束条件的分析研究,为下一步实现全面自愈奠定了基础。

With the gradual improvement of the reliability and advancement of the power grid,the self healing capability has become the core function of the advanced power grid system in the future.The research status and technical characteristics of the self-healing technology of the distribution network system and the rail transit power supply system were analyzed and compared,and the shortcomings of the current rail transit power supply system self-healing was pointed out;through sorting out the fault scenarios and self-healing requirements of the rail transit power supply system,the implementation method of the self-healing system was preliminarily analyzed,and an overall framework of the self-healing system was put forward.The analysis and research on the constraint conditions for the realization of self-healing function of rail transit power supply system will lay the foundation for the next step to achieve comprehensive self-healing.
