碩士 / 中原大學 / 電機工程研究所 / 94 / Peng-Hu is an isolated power system without having any links with Taiwan. There is only a Gen-San power plant with 12 diesel generators located in the main island. According to the load increasing, Peng-Hu power system need to build new plants, including diesel generator, wind power generator, offshore wind farm, and submarine cables that connect Peng-Hu power system with Taiwan. By the possibility of set up the new plants, that could have nice situations. After generators and submarine cables incorporating into the power system, it caused impacts in all respects. So this study considered evaluating every phenomenon, such as voltage fluctuation, voltage flicker, harmonic, safety of system, transient stability, underfrequency load shedding and overfrequency generator tripping.
For discussing the Peng-Hu power system’s transient stability, this study established the exciter and governor’s mathematic model of the diesel and wind generator. Because of wind couldn’t be forecasted, the large-scale offshore wind farm caused voltage flicker in the power system. This study considered nine system situations in 2011. It used PowerWorld Simulator to study the power flow and fault current, and using PSCAD/EMTDC to study voltage flicker and transient stability. By the strategy of the special protection system, planning the underfrequency load shedding and overfrequency generator tripping. Certain of the advantageous results toward building the every new plant are also provided in this paper.
