ABSTRACT
Reactive power compensation is the technique or practice used to control the reactive power circulation in the power system. It can be done by either absorbing or injecting the reactive power where it is needed. Distributed Static synchronous compensator (D-STATCOM) devices offer many potential benefits for power system operation to control the reactive power flow in the system. This paper focuses on the study of reactive power compensation of Metehara Sugar Factory in Ethiopia. As the collected data shows that, the factory is affected by overloading and low power factor problems. The Matlab simulation model of a Metehara Sugar Factory with and without D-STATCOM is implemented. The simulation results show that, without connecting D-STATCOM the power factor is 0.627 and per phase root mean square (RMS) voltage magnitudes are 182 v, 192 v and 198 v. This shows that RMS voltage and power factor of the loads are faced below international standard. By connecting D-STATCOM in parallel with the load side, the per phase magnitude of RMS voltage becomes 212 v, 218 v and 242 v. The RMS voltage after connecting the proposed device becomes in the range of standard value. D-STATCOM is a reactive power compensating device which injects and absorbs reactive power to support bus voltages in a distribution system.
