本文介绍了一工企直流电力牵引网计算机继电保护系统.系统中的高压测量监测信息用光纤传输,实现了高压电量检测及高压区与控制室之间的电气安全隔离。以单片计算机为核心的数据采集控制系统,实现数据采集和实时处理、故障识别及继电保护控制。该系统具有结构合理、投资少、功能强、可靠性高等特点,有很强的实用性和应用价值。
In this paper, a computer relay protection system for DC traction network is introduced in this paper.High-voltage measurement and monitoring information in the system is transmitted by optical fiber to achieve high-voltage power detection and electrical isolation between high-voltage area and control room. Monolithic computer as the core data acquisition and control system to achieve data acquisition and real-time processing, fault identification and relay protection control. The system has a reasonable structure, less investment, strong function, high reliability, strong practicality and application value.
