摘要
研究和开发了一种改进的地铁直流保护母线采集模块,用于地铁直流高压母线电压隔离、数据采集和传输。该模块应用FPGA(现场可编程门阵列)实现直流母线电压和电流等相关数据的采集,并且以光纤为媒介实现数据的传输。还详细介绍了该装置的实现方案、试验和试运行情况。实践表明,该装置不仅能够满足保护设备工作环境的高绝缘要求,也保证了数据传输的高速和高可靠性。
A kind of new DC bus sampling unit in metro DC protective system is designed and researched in this paper. lscd on the application of FPGA, the ,sampling unitis used for electrical isolation and thc measurement of current and voltage, in which the mcasured valut. arc sent to the PU (processor u- nit) via fiber optic cable. Thc design ~heme of this device is in- trocluced in detail, the expcrimental and application results indi- cate that this dcvice has good performance.
