摘要
介绍了一种以MSP4 30F14 9单片机为核心的数字式保护继电器及其软硬件的设计。该保护继电器实时监控电流信号 ,具有 3段电流保护和接地漏电保护等动作特性。硬件总体结构由开关电源、信号检测单元、微处理器系统以及执行元件 4部分组成 ,软件设计采用实时多任务操作系统作为运行平台 ,在运行中保证采样、计算、保护、控制等任务按时、有序、高效地完成。目前 ,该样机已投入运行 ,运行结果达到预期设计要求。
The hardware and software design of measuring and control unit based on microprocessor MSP430F149 for digital protection relay is focused in this paper. The protection relay monitors the signals of currents real time and has performance characteristics of three-sect current protection, grounding leakage protection and other protections. The hardware is composed of switch power supply,signal measuring unit,microprocessor system and execution component. The software system based on real-time multi-tasking operation system shows that it insures such tasks as sampling, calculation, protection and control to be completed on schedule, sequentially and efficiently. The relay has now put into practice, and the operating results reach the anticipated purpose.
