Title:
POWER SYSTEM STABILITY ANALYSIS APPARATUS AND METHOD
Document Type and Number:
WIPO Patent Application WO/2018/042506
Kind Code:
A1
Abstract:
The purpose of the present invention is to shorten calculation time in power system stability analysis, by designating an analysis time pitch width for each generator according to the level of shaking when an incident occurs. For this purpose, a power system stability analysis apparatus according to the present invention is provided with: a look-ahead calculation control unit that accepts information regarding analysis time pitches having different sizes as an input, and that performs look-ahead calculation with respect to generators to be analyzed while using, with respect to a generator with less shaking determined on the basis of the level of shaking when an incident has occurred or after the incident has been removed, by using an analysis time pitch which is not the minimum among the analysis time pitches having different sizes; and a look-ahead target generator designation unit that selects a generator for which look-ahead calculation is to be executed, and designates an analysis time pitch for a generator on which look-ahead calculation is not performed.
