Electromagnetic design considerations for fast acting controllers

Electromagnetic design considerations for fast acting controllers in a power system is introduced and defined. A distinction is made in relation to the more commonly understood system control design necessary for damping electromechanical oscillations using stability programs and eigenanalysis. Electromagnetic eigenanalysis tools have limited availability and are consequently rarely used. Electromagnetic transients programs (EMTP) on the other hand are widely used and a procedure for undertaking electromagnetic control design of fast acting controllers in a power system using EMTP is presented.
