Abstract

This paper presents the control of a synchronous reluctance generator (SyRG) driven by a biogas/biomass diesel engine as a prime mover in a distributed power generating system. This generator is used as a source to feed linear and nonlinear loads. A three-leg voltage source converter (VSC) based distribution static compensator (DSTATCOM) is implemented using adaptive neutral network based control algorithm for harmonics suppression, load balancing and voltage regulation in three-phase three-wire SyRG system with a battery energy storage system. This control algorithm is used for extraction of active and reactive power components of distorted load currents. These components of load currents are used for estimation of reference source currents to generate the gating pulses of VSC used as DSTATCOM. The performance of DSTATCOM is observed satisfactory for this type of generating system under balanced and unbalanced loads.
