10kV智能配电自动化终端应用分析

Application Analysis of 10kV Smart Distribution Automation Terminal

配电自动化是智能电网的重要基础之一,需要通过配电自动化系统采集尽可能多的配电信息,并向下延伸到低压用电信息的汇集。提出了一种新型智能配电自动化终端的设计方案,不仅可以检测和指示短路以及接地故障,还可以实时监测线路的正常运行情况和故障发生过程,其故障定位及在线监测系统还可以提供瞬时性短路故障、瞬时性和间歇性接地故障的在线监测和预警功能,以及故障后事故分析和总结功能,保证了配电线路的安全稳定运行。

Distribution automation is the important basis of smart grid, and it needs to collect the information of distribution equipment through distribution automation systems. Power consumption information is also collected by the system. A new design of smart distribution automation terminal is proposed. It can detect phase to phase faults and ground faults and give warnings. Besides, it can monitor the normal operation conditions and the procedure of the fault. Fault location and online monitoring system can also give early warnings when meeting with instantaneous faults or intermittent faults. What＇s more, fault accident analysis and concluding log functions are also provided to ensure the distribution line operate safety and stable.
