Development of a Geographic Information System based modeling of a shipboard power system
MetadataShow full item record
Since the early power systems in naval ships, there has been considerable advancement in technology. Today's naval ships carry an array of complex electrical and electronic equipment. A typical naval ship has electronics systems to cater to advance weapons systems, a complex drive, shipboard control systems, and equipment such as radar, sonar and communication systems. With the existence of such electrical and electronics equipment, which are vital to the functional ability of the ship, an information system is needed to manage the shipboard power system (SPS) data. During different operating conditions of the ship, the electrical topology of the SPS changes. The data representing the connectivity and the system state is needed. This is especially true during critical events such as battle scenarios. During these times, the present procedure of using paper-based maps and information charts to keep track of the system topology is not efficient. Geographic Information Systems, (GIS) were developed to address the need for managing complex spatial and attribute data. Geographic Information Systems are different from conventional information systems because they handle spatial and visual data. GIS technology has been used in several different industries including the electric utility industry to manage system facilities. In this thesis the author presents the process by which a GIS was created for a naval shipboard power system (SPS). The system consisted of a 3-dimensional layout diagram of the power system and a thorough database that stores the network topology and electrical parameters of the SPS. Also presented are standard modules developed for accessing the database data and the processes involved in integrating the GIS with other power system analysis tools such as a fault diagnosis method and a restoration/reconfiguration method. The GIS SPS provides a more efficient method to acquire system topology and system data under different operating conditions of a ship. This increases the overall survivability of the ship and provides the capability to use automated methods such as the fault diagnosis and restoration/reconfiguration methods to reduce the manpower required for the proper operation of a ship.
