Abstract: In order to solve the problem of long time for judging unbalanced three-phase voltage and one-phase ground fault line selection in distribution network, this paper adopted the visual basic for application (VBA) language to develop the auxiliary decision-making platform of distribution network. User forms were built in WPS table environment. The VBA language was used to write the automatic judgment program for three-phase voltage unbalance faults and the automatic inquiry program for bus information of grounded substation. The practical verification of distribution network auxiliary decision-making platform shows that this platform based on VBA can realize the auxiliary judgment of threephase unbalanced voltage fault in distribution network and the auxiliary generation of single-phase-to-ground bus line selection sequence.
Key words: visual basic for application; word processing system; user forms; three-phase voltage unbalance; auxiliary decision
