Analysis of Stability Control of a Power System with a Distributed Constant Circuit Model

From the load cut off tests on generators, 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 circuits. 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 method of suppressing the plural disturbances is discussed by employing the active sink method.
