Abstract :
The paper investigates the use of a novel filter arrangement for eliminating harmonic instability. The CIGRE benchmark model is selected as the base system. Presented in the paper is an example of harmonic instability which is first eliminated using a conventional low Q filter. Subsequently an energy recovery filter (ER-filter) replaces the conventional low Q filter. It is shown that the ER-filter provides similar performance with a fraction of the power loss when compared with a low Q filter. The dynamic performance of the ER-filter is also demonstrated via the simulations of system start-up and faults. The tool used for this investigation is an electromagnetic transient simulation program
