地铁系统作为城市电网中的关键高能耗负荷主体，其动态负荷特性对电力系统运行具有重要影响。本文针对地铁列车运行物理特性与电气特征的耦合关系，提出一种基于感应电动机等效模型的负荷建模方法。通过地铁列车运行的物理特征，结合地铁线路时空分布特征，并通过回归的方法将感应电动机负荷模型参数与地铁负荷用电时域特征进行对应，建立了考虑日周期运行模式和高峰时段密集发车的动态负荷模型。研究重点探讨了发车间隔调整、再生制动能量回馈等多因素耦合作用下的负荷特性演变规律，研究结果为城市电网负荷预测与优化调度提供了理论依据。
Abstract：As a key high-energy-consumption load entity in urban power grids, the metro system's dynamic load characteristics significantly impact power system operations. This paper proposes a load modeling method based on an induction motor equivalent model, addressing the coupling relationship between the physical operational characteristics and electrical features of metro trains. By integrating the physical characteristics of train operations with spatiotemporal distribution features of metro lines, and correlating induction motor load model parameters with temporal characteristics of metro power consumption through regression analysis, a dynamic load model that considers daily operational patterns and peak-hour dense train scheduling is established. The study focuses on investigating the evolution patterns of load characteristics under coupled factors including train departure interval adjustments and regenerative braking energy feedback. The research outcomes provide theoretical foundations for urban power grid load forecasting and optimal dispatch.
