| Popis: | 95 Hi-tech industry has become a necessary trend of industry development in Taiwan. However, despite of the research and development technology, the instability of power system will cause serious influence on both producing efficiency and amount of the Hi-tech industry. Therefore, supplied by stable power is a very important link to the basis of Hi-tech industry. For this idea, the study provides flywheel storage uninterruptible power supply. At first, we aimed at the flywheel energy storage system (FESS) and simulated the storage effect of FESS. Measure the features of recharge and discharge as the reference of control circuit. Then, according to the testing results, we can design a simulation circuit and test it to find out if the circuit can support the load stably when the power is interrupted. Realize the designed flywheel energy storage system and test its characteristic. Know from the test results, the output of this flywheel system is three-phrase AC variation power. So in this study, use power electronics techniques (pulse-width modulation, PWM) to have the system supply stable power. Compared to traditional batteries, this storage system doesn’t need high current and much time to recharge. In this study, improve the flywheel energy storage system and its equipment. Keep a longer power supply for industrial power consumption and lower all the costs and make the best economy efficiency. |
