<p><P>PROBLEM TO BE SOLVED: To allow a drop of voltage in a power transmission line to be within a permissible range after removing failure. <P>SOLUTION: An apparatus is provided for system stabilization in the power transmission system formed by interconnecting a group of generators each functioning as a power supply unit to a main system via the power transmission line. The apparatus includes: a preliminary operation device for previously operating a first power supply control amount of (a) and a second power supply control amount of (b) for each of failure patterns, where each failure pattern is defined as a pattern in non-route disconnection failure assumed in the power transmission system; a data table for storing each total power control amount of (c) in accordance with each of the failure patterns; and a power supply control execution device for reading a total power supply control amount corresponding to a generated non-route disconnection failure from the data table on the condition that the non-route disconnection failure occurs in the power transmission line, and controlling the power supply of the group of generators on the basis of the read total power supply control amount. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
