As most of loads are of inductive type, the power system is in lagging power factor and as a result poor power quality is occurred. And it is demanded to make power factor correction to be better power quality of power system. Among power factor correction devices, synchronous condenser is studied in this paper to improve the industrial loads. There are ten numbers of induction motors in Tharpaung pulp plant and the net power factor of the factory power system is round about 0.85 lagging. By using 0.75 leading power factor of synchronous condenser, the system power factor is improved to 0.969 lagging. And it is studied to choose the appropriated synchronous condenser of power factor and rating for various system power factors. And if there are different operating times for each induction motors, which synchronous condenser should be run is studied in detail in the paper. It is shown that the use of synchronous condenser improves the system power factor and makes power quality better. In this study, MATLAB program is used for overall plant power factor calculation.
