SYSTEM, METHOD FOR MONITORING VOLTAGE STABILITY OF POWER SYSTEM, AND A MEDIUM HAVING COMPUTER READABLE PROGRAM FOR EXECUTING THE METHOD

摘要

PURPOSE: A power system voltage stability inspection system, a method thereof, and a media thereof are provided to analyze a power system stability without errors by calculating data at the transmission spot using the data measurement value at the measuring spot. CONSTITUTION: A data measurement part(110) measures a measuring spot voltage and current in the predetermined measurement spot of a transmission line. A voltage stability determination part calculates a load terminal side equivalent impedance at the measurement spot. The voltage stability determination part calculates a voltage and current at the transmission spot. The voltage stability determination part(120) generates power generating terminal equivalent impedance at the power transmission spot. The voltage stability determination part generates transmission terminal equivalent impedance at the measuring spot.
