Reactive Power Compensation

OBJECTIVES

After reading this chapter, you should be able to:

  • know the need of reactive power compensation
  • discuss the objectives of load compensation
  • discuss the operation of uncompensated and compensated transmission lines
  • discuss the concept of sub-synchronous resonance (SSR)
  • study the voltage-stability analysis
9.1 INTRODUCTION

In an ideal AC-power system, the voltage and the frequency at every supply point would remain constant, free from harmonics and the power factor (p.f.) would remain unity. For the optimum performance at a particular supply voltage, each load could be designed such that there is no interference between different loads as a result of variations in the current taken by each one.
