Power Quality Improvement of Large Power System Using a Conventional Method
Abstract: Operation of a large power system with maintaining proper power quality is always been a difficult task. It becomes more difficult to maintain the power quality when rapid expansion of previously designed power system occurred. To redesign of such a power system is not feasible and also cost effective. To improve the quality of power of such a large system, conventional methods of compensation can be used. In this paper a power system of 419 buses is analyzed. It is found that 76 buses have under voltage problem. Conventional shunt compensation method is used by connecting capacitor in parallel to the bus. After compensation the system is simulated again and found that the under voltage problem of this large power system is removed. Power factor of the system is also improved.
