A novel electrical equipment on-line monitoring system based on geographic information system

Recently more and more single parameter electrical equipment on-line monitoring systems are being put into use. How to rationally fuse the on-line insulation monitoring information of this location dispersed equipment and thus to realize effective management of the on-line monitoring information from them and rationally analyze the specific electrical equipment are the questions which should be solved urgently. Geographic Information System (GIS) is used in this paper for the fusion of the on-line insulation information of the equipment within the different substations and different locations in the same substation and a multi-parameter method is used to analyze the insulation status of the specific electrical equipment. A novel electrical equipment on-line monitoring system with multi-parameters based on GIS is proposed, the means and steps for the construction of this system are explained through examples. Application results show that this method can overall reflect the running status of electrical equipment and greatly reduce the losses caused by sudden faults. Therefore, this method can meet the needs of modern management of power systems
