【摘要】：配电自动化能对配网设备运行情况进行有效监控和管理,而衡量一套配电自动化系统坚强与否的关键要看其终端单元的在线率是否达到要求。以DTU离线故障和通信网络中断为切入点,采用模块化控制策略和改进型程序重置技术对DTU内核软件进行了功能性扩展和二次开发,实现了DTU离线故障的自诊断、自愈以及部分附加功能,从而显著缩短了DTU离线故障处理时间,大幅减少了终端单元与自动化主站之间数据传输的盲点。
[Abstract]:Distribution automation can effectively monitor and manage the operation of distribution network equipment. The key to measure the strength of a distribution automation system depends on whether the on-line rate of the terminal unit meets the requirements. Taking DTU off-line fault and communication network interruption as the breakthrough point, the function extension and secondary development of DTU kernel software are carried out by using modularized control strategy and improved program reset technology, and the self-diagnosis of DTU off-line fault is realized. The self-healing and some additional functions can shorten the processing time of DTU off-line fault and greatly reduce the blind spot of data transmission between terminal unit and automatic master station.
