Projeto de sinais estabilizadores em compensadores estáticos de reativos baseado em técnicas de controle moderno e teoria da identificação.

Abstract

This work presents a design of stabilizing signals for static reactive compensators derived from active power flow variations in the line and / or modulus of the voltage in the busbar and / or voltage angle in the compensator / remainder bar of the C.A. system in order to dampen the oscillations of these variables under small disturbances in the heavily loaded power system. The project is based on the state optimization strategy for a linearized model of the compensator connected to a dynamic equivalent model of a large power system. Some C.A. system variables required for the project, but not represented in the dynamic equivalent model, are identified by the generalized recursive least squares method and incorporated into the system. Finally, implementation tests are done using CHESF's 500 kV west system.
