Intelligent detection system of tramcar power grid based on SA9904B

本文详细讨论了电车电网的智能监控系统的硬件设计方案和软件实现过程。该系统实现的功能包括电车电网参数的检测和显示,电网故障的识别和报警,电网运行参数的记录,和电网数据的传输。其中采集的电网参数包括三相电压、三相电流、无功功率、有功功率、功率因数、频率等。系统的电量采集模块采用了一片电能计量芯片SA9904B。微控制器采用TI公司的TMS320LF2407A。

This paper discusses hardware design scheme and software implementation process of intelligent detection system of tramcar power grid in detail. The functions of this system include detecting and displaying power grid parameter, identifying power grid fault, recording running parameter and transmitting power grid data. Power grid parameters collected include three-phase voltage, three- phase current, active power, passive power, power factor, frequency and so on. The parameter collection module of this system uses one chip called SA9904B. TMS320 LF2407A of TI Company is adopted as MCU.
