摘要
详细介绍了基于IEC61850-9-1的新型保护测试仪的实现原理和硬件结构,并对数字保护的测试做了简单介绍。该装置基于DSP和嵌入式ARM微处理器,前者完成测试数据的计算和打包,后者负责完成与上位机的以太网通信,测试数据的打包和发送。测试数据满足IEC61850-9-1的通信协议,由上位机软件界面设定,按照一定的试验方法,将光纤数字量送至数字化保护,并通过测试仪的开关量输入接点接收保护的动作信息。
This paper introduces new types of relay protection tester's principle and hardware structure based on IEC61850-9-1 in detail. The device is based on DSP and embedded ARM microprocessor, the former is to complete the task of calculating and packing, the later is to complete the Ethernet communication with PC and packing and sending testing data which is according to the standard IEC61850-9-1. Set parameters on the PC's software interface, and then transmit the fiber signal to the digital protector and receives the action information through the input connector of the tester.
