碩士 === 明新科技大學 === 管理研究所碩士在職專班 === 105 === The power supply system is the main source for the public infrastructure in ITRI Guangfu District. The system is a single loop system. It was constructed in 1983, and has been operated for more than 33 years. Since the need of electricity has grown during these years, the probability of the power cutoff may increase, and the use of the system may cause great economical losses, because the power cannot be immediately restored in cases such as abnormal performance of high voltage cables when using the system. Thus, I thought that the system needed to be improved. After summarizing the opinions of owner (ITRI Guangfu District), architects, electrical technicians and electromechanical consultants, I focused on the improvements of the three parts in the old system, that is, the total substation, the high voltage relay station double switch, and the high pressure plate monitoring shift control system. Next, I used the method of resolve technical contradictions in TRIZ theory to help me found out the most practical scheme for the improvement, and the best scheme was the addition of "the addition of high-voltage vacuum circuit breakers", "switch box to add foolproof device", and "additional shift switch" in the previous system.
