As a section of electric power system linked with Kepco was changed, the decrease in qulity of the electric power transmitted to the Hapcheon hydraulic power station occurred. The actual state bring about the overheating and capability decline of electricity accommodation equipment. From now, let's improve the efficiency on the maintenance of generating equipment by studying about the cause and the method for this problem.

Auto-synchonizer is important device to match the voltage, frequency, phase of the generating system to those factors of the transmission line, when the synchronous generator is operated. There were few or no incidents by Synchronization failure at Hapcheon hydraulic power plant, since it was built in 1989. but incidents by Synchronization failure have often happend lately. From now, let's improve the efficiency on the maintenance of generating equipment by studying about the cause and the method for this problem by comparing with the set point of each device of synchronizing system.

In design PV(photovoltaic) system, there are many important factors to consider for best site selection. It is essential to understand to know the amount of sunlight available and how to minimize the shadings. This study presents basic concepts for understanding sun's position and insolation. also gives easy tools for topography analysis. Finally, this study shows some theoretical calculations of power generation losses and disadvantages in economic feasibility.

It is essential to understand to know the amount of sunlight available and how to minimize the shadings. This study presents basic concepts for understanding sun's position and insolation. also it gives easy tools for topography analysis. Finally, this study shows some theoretical calculations of power generation losses by topographic obstacle's elevations and disadvantages in economic feasibility, that is about 7million won loss per year for case of 10 degree topography elevation with assuming average Korea's topography elevation as 5 degree.
