LOAD SHEDDING APPARATUS USING VOLTAGE STABILITY INDEX

摘要

Disclosed is a load shedding device and method utilizing a voltage stability index. The load shedding device using the voltage stability index of the present invention includes: a detection unit for detecting monitoring information on a transmission line; An operation unit that creates a line constant table using the monitoring information, configures the Thevenin equivalent circuit based on the line constant table, and calculates a voltage stability index based on the complex power ratio using the Thevenin equivalent circuit; A determination module for determining whether to cut off the load based on the voltage stability index calculated by the calculation unit and the active power and voltage of the transmission line; And it characterized in that it comprises a load blocking unit for blocking the load according to the determination result of the determination module.
