Abstract
For a primary substation (P/S), there are many typical methods to control voltage and reactive power such as adjusting the generator mode, switching shunt capacitor (SC), adjusting on-load tap changer (OLTC), and switching shunt reactor (SR). In this study, a graphical user interface (GUI) is designed combining with nine-area diagram to observe the relationship between voltage and reactive power in a P/S. This GUI not only predicts the effect to dispatchers in short time but also analyzes the sensitivity parameters. Field measurement data were analyzed. Simulation results confirmed the feasibility of compensating the reactive power and adjusting voltage simultaneously.
