ABSTRACT

Ho Chi Minh City Power Corporation (EVNHCMC) is step by step implementing the goal "Modernizing management and operation of low voltage electricity distribution network " in order to build a smart power supply system that best serves customers

The research was carried out, in order to evaluate the capacity application of GIS (Geographical Information System) in Go Vap district in improving the management and operation of low voltage power network at Go Vap Power Company

The results of this study is not only improve the ability to effectively share and use data within Vietnam Electricity Corporation, but also contributes to creating useful tools in operation of power system

The proposed solutions have contributed to standardizing the GIS database

of low-voltage power networks based on the Geodatabase model, in order to develop software of GIS applications for exchanging synchronous information between Go Vap Power Company with the Center of Customer Care

In addition, GIS tools are built to support operations such as customer information retrieval; calculate the power supply length of substations; visual control of stations with a grid radius of over 300m, to support the reduction of power loss in managing low-voltage power networks in Go Vap district

The general solution model of GIS application in management and operation

of low voltage power network will contribute to establish a unified procedure and data standards, in order to build database management system (DBMS) for the smart electric networks at EVNHCMC
