新型继电保护实验平台建设

Building of Novel Platform for Relaying Protection Experiment

继电保护实验是电气类专业的重要教学内容。笔者针对目前普遍存在继电保护实验技术设备落后,不能很好适应继电保护教学和技术发展需要的情况,研究了继电保护实验的特点,并建设了具有良好扩展性、技术较为先进且满足教学实验需要的新型继电保护实验平台。本平台包含传统继电器保护、微机保护等多个实验内容,并采用网络化结构,通过RS485总线实现保护试验台和工控机间的信息交换,可实现部分SCADA功能。

Relaying protection experiment is very important in the teaching of electric engineering speciality. Devices for relaying protection experiment are generally backward and fail to satisfy the need of teaching and technology development nowadays. On the study of Relaying protection experiment, a novel platform for relaying protection experiment with advanced-technology and good-scalability is built. The platform includes traditional relay and microcomputer-based protection experiments. It uses network structure and exchanges information between the protection platforms and the industry-control computer through the RS485 bus, and it can realize parts of SCADA function.
