In this paper, we present a prototype of a DMS -Distribution Management System -using Object Oriented technology and a modular distributed multitask client-server architecture. The DMS is supported by an Object Oriented model in which the power system components are considered objects grouped in several classes according to their characteristics. The power system applications are software modules within this base platform that is physically located in a WEB server and are implemented in Java or C++. The users should connect to an HTML page in the server, download the desired applet to the client's machine establishing communication, interfaces and requesting services to the main system. The paper gives a global overview of the system, describes its architecture, gives details about the Database organization and describes the main characteristics and features of some power system applications as Topology Processor, Single Phase Power Flow and Symmetric Short Circuit.
