| Summary: | 碩士 === 逢甲大學 === 電機工程學系 === 104 === This study is about the designing of energy storage system for electrical train system. In 2016, there are two units of electrical train (EMU700 and EMU1000) which are installed by regenerative braking system owned by Taiwan Railway Company. Braking system will turn the motor into a generator during the deceleration by brake and store the regenerated energy into the energy storage system for the train usage. The regenerated energy sometimes will exceed the amount of the energy which can be stored and affect the component in the train. Therefore the extra energy will be flown into the braking resistor and turned into heat energy. To solve this problem, extra energy storage system needs to be installed. By the extra energy storage system, it will increase the efficiency of the energy usage management and increase the amount of the energy which can be stored. In additional, the stored extra energy can be used as additional energy to stabilize the energy fluctuation of the train. There are many types of energy storage system but only few of them which are compatible for electrical train system. Therefore it needs to be carefully selected. By using MATLAB SIMULINK software, the whole system which consisted of energy storage system and electrical operational train system are simulated to get the best and more efficient result of operational. This simulation is also used to study the regenerated braking energy and its effect on the electrical train system. At the end, the result of this study are compared with the study of train operational strategy system to observe the advantages and disadvantages of each system.
