Performance Evaluation of SCADA System Isolating Fault Section in a Demand Area Power System

SCADA (Supervisory Control And Data Acquisition) systems for demand area power systems (one of the next-generation distribution grids) would be required; 1) to be flexible, 2) to provide various functions on restricted computing resources, and 3) to complete processing within the period required. We have proposed a system design based on mobile agents and Ethernet in order to fulfill the first and second requirements. This paper shows that this system design would satisfy the third requirement. In order to validate the system performance, we constructed an experimental system composed of a distribution line, generators, power devices, computers, mobile agents and Ethernet. The experiment results illustrate that a system based on this design could complete the fault isolation process that has the most stringent execution period.
