This paper presents an adaptive control algorithm called improved linear sinusoidal tracer (ILST) for a three-phase distribution static compensator (DSTATCOM) to perform different functions like reactive power compensation, harmonics elimination, load balancing, and voltage regulation under linear and nonlinear loads. A prototype DSTATCOM is developed using a digital signal processor to test the control algorithm in real-time. The performance of the DSTATCOM with the proposed ILST control algorithm is found to be satisfactory under various load conditions.

- 1. ADAPTIVE THEORY-BASED IMPROVED LINEAR SINUSOIDAL TRACER CONTROL ALGORITHM FOR DSTATCOM ABSTRACT: This paper presents a hardware implementation of three-phase distribution static compensator (DSTATCOM) using an adaptive theory-based improved linear sinusoidal tracer (ILST) control algorithm for different functions of DSTATCOM such as reactive power compensation for power factor correction, harmonics elimination, load balancing, and zero-voltage regulation under linear/nonlinear loads. An ILSTbased control algorithm is used for the extraction of fundamental load currents and their active and reactive power components. These components are used for the estimation of reference source currents. A prototype of DSTATCOM is developed and its real-time performance is studied using a digital signal processor. The performance of DSTATCOM is found satisfactory with the proposed control algorithm under various types of loads.
