An improvement of compensators of complete power non-active components in autonomous electric power systems

The certain embodiments of adjustable power line conditioners (APLC), comprised in autonomous electric power systems (EPS) with powerful semiconductor converters, was considered in this article. The basic equations for the calculation of main parameters and characteristics of APLC were presented. The comparative analysis of the embodiments of APLC was performed based on the results of computer simulation and has shown their impact on the inactive components of the total power and non-sinusoidal characteristics of voltage and current consumed by autonomous EPS. The most effective scheme of APLC is proposed, which consists of an unregulated resonant filter and controllable reactor compensator with PWM control.
