Abstract
From a shut down test of generator and electric load in the power system, it is well known that the power disturbance is transmitted from the test point to the other points with constant delay time. The phenomena shows that the electric power system has a similar dynamic characteristic to the distributed constant circuit. On the other hand, in the case of a simulation with lumped constants, such as the detailed conditions in connected generators must be understood, and the analysis becomes complicated. In this paper, the electric power system is expressed with the distributed constant circuit, so that the main disturbance characteristics are obtained without difficulty. Moreover, the possibility of suppressing the disturbance is discussed by employing active sink method.
