Information Physical Fusion Protection System of Intelligent Distribution Network Based on Computer Network

智能配电网的应用提高配电作业质量和效率的同时,也使故障影响更加难以控制。为此,开发一款针对配电网的保护系统。该系统首先选取电流信息采集设备——电流互感器,并将其布置在配电网上,采集配电网上的电流信息,然后通过计算机网络传输组件将信息传输到DSP芯片当中并进行处理与分析,实现故障判断、故障定位,最后根据判断和定位结果,给出故障处理方案,控制隔离保护设备将故障部分从配电系统中切除,保护非故障区域不受影响。结果表明:所设计系统应用下,配电网故障判断、故障定位以及故障处理等系统模块给出的结果与设定结果一致,且完成时间在10 s之内,由此说明本系统能够快速且准确地分析配电网故障并给出处理方案,实现供电作业的快速恢复。

The application of intelligent distribution network not only improves the quality and efficiency of distribution operation,but also makes the impact of fault more difficult to control.Therefore,a protection system for distribution network is developed.The systemfirst selects current information acquisition equipment current transformer and arranges it in the distribution network to collect the current information of the distribution network,then transmits the information to the DSP chip through the computer network transmission module for processing and analysis,so as to realize fault judgment and fault location.Finally,according to the judgment and location results,the fault treatment scheme is given.The control isolation protection equipment removes the fault part from the distribution system to protect the non fault area from being affected.The results show that:under the application of the designed system,the results given by the system modules of distribution network fault judgment,fault location and fault treatment are consistent with the set results,and the completion time is within 10 s,which shows that the system can quickly and accurately analyze the distribution network fault and give the treatment scheme,and realize the rapid recovery of power supply operation.
