UNIT I   INTRODUCTION                                                                                               9

Introduction – Characterisation of Electric Power Quality: Transients, short duration and long duration voltage variations, Voltage imbalance, waveform distortion, Voltage fluctuations, Power frequency variation, Power acceptability curves – power quality problems: poor load power factor, Non linear and unbalanced loads, DC offset in loads, Notching in load voltage, Disturbance in supply voltage – Power quality standards.

UNIT II   ANALYSIS OF SINGLE PHASE AND THREE PHASE SYSTEM                      9

Single phase linear and non linear loads – single phase sinusoidal, non sinusoidal source – supplying linear and nonlinear load – three phase Balance system – three phase unbalanced system – three phase unbalanced and distorted source supplying non linear loads – convept of pf – three phase three wire – three phase four wire system.

UNIT III     CONVENTIONAL LOAD COMPENSATION METHODS                                 9

Principle of load compensation and voltage regulation – classical load balancing problem : open loop balancing – closed loop balancing, current balancing – harmonic reduction and voltage sag reduction – analysis of unbalance – instantaneous of real and reactive powers – Extraction of fundamental sequence component from measured.

UNIT IV    LOAD COMPENSATION USING DSTATCOM                                                 9

Compensating single – phase loads – Ideal three phase shunt compensator structure – generating reference currents using instantaneous PQ theory –  Instantaneous symmetrical components  theory  –  Generating  reference  currents  when  the  souce  is  unbalanced  – Realization and control of DSTATCOM – DSTATCOM in Voltage control mode
