摘　　要：本文针对变电站综自系统高压继电保护装置随控制屏配置的就地打印机存在频发性故障,降低了运维效率问题,提出一种继电保护装置的集中式打印技术方案,通过将若干继电保护装置串口通信线近距离汇聚接入打印数据集中器,再以虚拟串口方式接入打印服务器,通过解析采用标准打印控制协议的继电保护信息,实现继电保护装置打印信息的集中可视化展示和打印输出,本技术方案具有投入少、接入方便、不影响现有设备运行的优点,非常适合变电站综自系统的技术升级改造。This paper focus on defection of frequent printing failure which is found in high voltage relay protection devices configured in substation automation system. And propose a protection device centralized printing technology scheme which is implemented by connect the printing serial communication port to print data sample device directly, and the send the printing data to the central printing server via virtual serial communication port technology. The printing server analyses relay information using standard print control protocol, so the relay protection printing information can be displayed and printed.This scheme has advantages such as small investment, convenient access, little infect on working devices etc. and suitable for device upgrade of substation automation system.
