摘要
基于天津地铁在中压逆变回馈装置应用方面的实践经验,从系统安全性、保护配置、阈值设定、控制系统等方面分析技术可行性评价需考虑的关键问题。结合天津地铁7号线的线路条件,阐述用系统仿真软件进行节能效果分析时需考虑的因素,并进行数据计算及对比分析,给出系统容量选择时参考值的确定及校核方法。
The application of a medium-voltage inverter feedback device to the Tianjin metro is introduced. Firstly, the key issues to be considered with respect to technical evaluation are introduced from the perspective of system safety, protection configuration, threshold setting, and control system. Based on the line conditions of the Tianjin Metro Line 7, the factors that should be considered when system simulation software is used to analyze energy-saving are presented, as well as the process of data calculation and comparative analysis. The method of determining and examining the reference value for the selection of the capacity is then briefly described. Finally, the development of the device for auxiliary traction power supply, reactive power compensation, and intelligent ice melting are examined.
