The invention relates to an intelligent control method for a rail transit traction power supply system. The intelligent control method comprises the following steps of data collection, wherein power monitoring system data, signal system data and train operation data are collected in real time; data processing: preprocessing the collected real-time data, including delay compensation and abnormal data correction; optimization control: based on the compensated and corrected data, performing operation by using an intelligent algorithm, and determining a power distribution scheme of the direct current network; instruction issuing: converting the optimized power distribution scheme into a control instruction, and sending the control instruction to each converter station control center through the Ethernet; and system adjustment: each converter station control center adjusts the terminal voltage of the station according to the received control instruction to form system closed-loop operation. The technical problems that in the prior art, regenerative braking energy of a rail transit traction power supply system cannot be efficiently recycled, the direct current network voltage is uncontrollable, and the efficiency of the power supply system is low are solved.

    本发明涉及一种轨道交通牵引供电系统智能控制方法,包括以下步骤:数据采集:实时采集电力监控系统数据、信号系统数据和列车运行数据;数据处理:对采集的实时数据进行预处理,包括延时补偿和异常数据修正;优化控制:基于补偿和修正后的数据,利用智能算法进行运算,确定直流网的功率分配方案;指令下发:将优化后的功率分配方案转化为控制指令,通过以太网发送至各换流站控制中心;系统调整:各换流站控制中心根据接收到的控制指令调整站点端电压,形成系统闭环运行。本发明解决了现有技术中轨道交通牵引供电系统再生制动能量无法高效回收再利用、直流网压不可控和供电系统效率低的技术问题。
