Voltage/Reactive power planning is very tremendous process which requires a planner to have intellectual expertise. This paper presents the large knowledge based system that can make the voltage/reactive power planning. The knowledge acquisition has been completed on the basis of interview and protocol analysis methods. The result shows that the voltage/reactive power planning is composed of three phases.
The first is reactive power adjustment where overall reactive power balance is investigated. The second is voltage adjustment where all bus voltages are tuned within permissible operational range. The third is voltage adjustment with a single fault of all major lines. The knowledge base is coded by about 700 production rules. It can succeed in making a voltage/reactive power plan for a real large power system.
