The longitudinal power system in Taiwan suffers from two major problems, i.e., the area generation-load unbalance in the three areas and the disproportionate power flows over the two existing parallel corridors. Consequently, low voltage profiles have been observed on O-MEI bus for the system under normal operation or under some outage conditions. It is thus necessary to devise some proper means to improve the O-MEI bus voltage to prevent the system from voltage instability. Besides, it is also important to improve the dynamic voltage responses under sidturbance conditions. In the present work, STATCOMs will be employed to promote steady-state voltages and to improve the dynamic voltage responses on O-MEI bus. In phase 1 of this three-year project, the steady-state voltage profiles and dynamic voltage responses of O-MEI bus after STATCOMs are installed will be analyzed. The effect of the capacities of STATCOMs on steady-state voltage will be investigated.application/pdf537165 bytesapplication/pdfzh-TW國立臺灣大學電機工程學系暨研究所靜態同步調相器動態電壓響應無效電力補償static synchronous compensators (STATCOMs)dynamic voltage responsereactive power compensationreporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/7930/1/912213E002114.pdf
