摘　　要：基于STM32嵌入式系统的电网短路故障指示器设计方案,通过测量数据能准确指示故障发生的局域,并通过CAN总线发送到监测中心,使电网得到及时的保护。方案中选用了STM32系列微控制器和ATT7022E/26E/28E系列多功能高精度三相电能专用计量芯片,在传统故障指示器的基础上,提高了系统的集成度和检测数据的速度。指示器具有体积小、重量轻、报警迅速和使用寿命长等特点。This paper presents a new design of shorted fault indicator based on STM32. The indicator can accurately indicate the fault location correctly. It sends fault message to the monitoring center of electrical grid wireless through the CAN bus to con- trol the distribution network. The program selected Embedded MPU - STM32and ATT/022E/26E/28E , based on the traditional fault indicator on increasing the speed of the system integration and test data. Based on the traditional fault indicator, it increases the speed of data integration and testing of the system. Indicator has small size, light weight, quick alarm, long service life.
