STATIC REACTIVE POWER CONTROLLER MODEL FOR ANALOG SIMULATOR

摘要

PURPOSE:To realize faithful simulation of the operation of a reactive power controller in an actual power system by an arrangement wherein a desired output current can be produced according to the capacity of a simulator. CONSTITUTION:A current flowing through a reactor model 6A is subjected to phase control by means of a thyristor model 6B and detected through a current detector 5 thence fed to an input level regulator 15. The current fed through the input level regulator 15 is amplified through a current amplifier 3 to produce a three-phase current control command which is then fed, as an SVC model output current, toward a transmission line model 1. The level of the output current can be regulated by means of an output level regulator 16. According to the constitution, the SVC output current can be set appropriately even for different rated capacity of an object system to be analyzed, resulting in faithful reproduction of reactive power control in an actual system.
