Distribution System Relay Setting Calculation Based Upon MIS

The topological relation and manufacture information are gotten by using the existing data from MIS. Relay Setting Calculation System in distribution network is developed with PowerBuilder. The buffer method is used in distribution network Relay Setting Calculation to avoid the repeatable calculation of fault data. Topological arithmetic is advanced by making sue of the spare time of drawing with Object Oriented method.The protection virtual protection and real protection illustrate protection configure, so topological arithmetic can be applied in multi-T line and line with no protection at the terminal .Using the standard fault calculation method ,the standard model with different parameter fill needs to speediness and precision of fault computer calculation.
