【摘要】 针对目前中小型变电站所使用的直流电源系统存在的一些问题,提出了相关的解决方案,设计了一套新型直流操作电源管理系统。系统以微控制器为核心,采用高精度的TMS320F2812定点32位DSP芯片对直流系统的各种功能统一管理,并通过DSP的串行通信接口SCI实现与上位机的通信。上位机的监控程序利用可视化程序设计语言VisualBasic6.0设计开发,实现了对各种信息的实时显示与报警。更多还原

【Abstract】 Considering the problems of the direct current(DC) power supply systems of small and medium substations,a relevant plan is put forward and a new DC power supply system is designed.This system uses micro-controller as its key part and adopts TMS320F2812 DSP with high precision to unitedly administer all functions of DC system.The communication between DSP and upper computer is completed by serial communication interface(SCI) of DSP.The supervision program of upper computer is developed by Visual Basic 6.0.The real-time display and alarm of various information are also realized.更多还原
