TROUBLE DIAGNOSING and PROCESSING METHOD OF POWER NETWORK

摘要

The power grid failure analysis processing method of the present invention includes the steps of recognizing the occurrence and location of a ground fault in the power grid; Constructing a Norton equivalent circuit and a Thevenin equivalent circuit for each power source included in the power grid, and analyzing the effect of the ground fault on the power grid by superimposing calculation results of the equivalent circuits; And determining a countermeasure for the ground fault from the analysis result.
