Abstract- [7]. The purpose of this work is to generate explicit equations for the permittivity using a straightforward scattering parameters model for load-terminated samples. II. PERMITTIVITY MEASUREMENT METHODS A. Historical DevelopmentIn 1946, Roberts and Von Hippel [8] presented a method for the measurement of permittivity using an air-filled rectangular waveguide with a sample of MUT in the end of the waveguide.

This paper presents initial project and test results of an active power control scheme development for auxiliary synchronous generators of an AES-Distribution System connected Hydraulic Generation Unit. An open loop control system using TCSC switched by IGBT's is proposed to compensate the inductive impedance of the synchronous generator and control the active power injection. Several switching angles were evaluated at different compensation levels and simulations are presented to analyze the effectiveness and robustness of the proposed controller project.
