摘要
针对现有配电网在故障检测、故障后的供电恢复以及配电网的负荷专供等方面均存在的不足,文中设计开发了一套基于EPON通信技术的配网自动化系统。该系统在下行方向采用广播的方式来传递数据帧,使得数据从光线路终端OLT传递到光网络单元ONU,而在上行数据则是通过时分复用的方式实现ONU到OLT的传递,这种双向通信的模式完成了对各终端设备以及系统运行参数的自动化监控和处理。系统测试结果表明,该配网自动化系统在稳定程度、数据处理效率及信号传输速度等方面均能够满足电力企业对于配网系统的实际要求。
In view of the shortcomings of existing distribution network in fault detection,power supply recovery after fault and load exclusive supply of distribution network,this paper designs and develops a distribution automation system based on EPON communication technology.In the downstream direction,the system transmits data frames by broadcasting,which transfers data from the optical terminal OLT to the optical network unit ONU,while in the upstream direction,the transmission of ONU to OLT is realized by time division multiplexing.This two-way communication mode completes the automatic monitoring and processing of terminal equipment and system operation parameters.The system test results show that the distribution automation system can meet the actual requirements of power enterprises in terms of stability,data processing efficiency and signal transmission speed.
