Direct Calculation of A Matrix of Single Machine Connected to Infinite Bus : Including Excitation System

발전기-무한모선계통의 A행열의 직접 계산법 : 여자계통을 고려한 경우

Direct calculation algorithm for the elements of A matrix is suggested for a single machine connected to the infinite bus. Excitation system and power system stabilizer are included. When A matrix is partitioned into seven submatrices, we can identify the location of non-zero elements and formula for each element. No matrix inversion and multiplication are necessary.
