To facilitate the movement of fighter jets, the height restrictions are imposed on the surrounding buildings so that the airfield will not constantly face very strong wind gusts. During the typhoon season, there’s even the case where the top plate of the armored HV box was lifted off by the wind and it may hurt the persons working on the field or the fighter jet when taking off or landing. In view of this, it would be required to improve the high-voltage power supply system. As the national defense budget is originated from the taxes paid by the people, it is required that a cost-efficient solution must be developed to solve the current situation. To improve the electrical efficiency to the Hsinchu Air Force Base thus enhancing the stability of the power supply system and to prevent the equipment and armored box in the field from being blown off by strong winds, this research suggests that the transformer should be entirely changed to the pad-mounted transformer to reduce the unexpected power interruption event by updating the equipment. In the meantime, the cost-efficiency of changing to the pad-mounted transformer is analyzed through the Net Present Value, Internal Rate of Return, and Transformer Operating Cost Analysis. After being calculated, the results indicated that it would be less cost-efficient when changing to the pad-mounted transformer; therefore, the more high efficiency transformer is used as an alternative in certain areas. Under the condition of meeting the cost-efficiency and the requirements of the Hsinchu Air Force Base, the Net Present Value and Internal Rate of Return were selected again to Transformer Operating Cost Analysis. After evaluating the cost-efficiency with the aforesaid two methods, it was found that the cost-efficiency of the high efficiency transformer was higher than the pad-mounted transformer. To prevent the strong winds on the field and achieve more effective cost-efficiency, it is suggested that the pad-mounted transformer be selected for the field area and the high efficiency transformer be used in other administrative areas. After being calculated, such kind of combination will be the optimum solution and it will be proposed for the Hsinchu Air Force Base for use as the reference of the subsequent HV power supply system improvement plan.

To improve the electrical efficiency to the Hsinchu Air Force Base thus enhancing the stability of the power supply system and to prevent the equipment and armored box in the field from being blown off by strong winds, this research suggests that the transformer should be entirely changed to the pad-mounted transformer to reduce the unexpected power interruption event by updating the equipment.

Under the condition of meeting the cost-efficiency and the requirements of the Hsinchu Air Force Base, the Net Present Value and Internal Rate of Return were selected again to Transformer Operating Cost Analysis.
After evaluating the cost-efficiency with the aforesaid two methods, it was found that the cost-efficiency of the high efficiency transformer was higher than the pad-mounted transformer. To prevent the strong winds on the field and achieve more effective cost-efficiency, it is suggested that the pad-mounted transformer be selected for the field area and the high efficiency transformer be used in other administrative areas.
