Abstract: 本論文之主要目的是研究靜態同步補償器和電力系統穩定器對系統電壓、系統動態電壓的影響。另外,討探系統動態電壓時,也發現了低頻振盪,這是台電系統過去曾經發生的一個問題。
在本研究中將討論,當遇到比較嚴重的事故時,靜態同步補償器的裝設地點、容量及其改善後的穩態電壓。另外,加裝靜態同步補償器後的動態電壓,將會分析其組合比例的阻尼比差異,並觀察其電壓波形。在靜態同步補償器和電力系統穩定器的方面,觀察在嚴重事故發生時,其電壓波形、阻尼比、振盪頻率的變化,來分析兩者之間是否有相互影響的情形發生。
研究結果顯示,靜態同步補償器對穩態電壓有相當不錯的改善效果,而靜態同步補償器和電力系統穩定器在阻尼比上對系統都是正向的幫助;低頻振盪方面,靜態同步補償器同樣也有改善阻尼比的效果,並沒有不良的影響出現。
The main purpose of this thesis is to examine the effect of Static Synchronous Compensators (STATCOMs) and Power System Stabilizers (PSSs) on the voltage and dynamic performance of Taiwan power system. Damping characteristic of low frequency oscillation modes in Taiwan power system was also investigated.
The location and capacities of the STATCOMs are first determined. The dynamic voltage responses and damping ratios for the system with fixed capacitors and STATCOMs are compared. The effects of STATCOMs and PSSs on the damping tatios for the low frequency electromechanical modes are also invertigated.
It is found that the dynamic voltage profile can be improved by the STATCOMs. In addition, both STATCOMs and PSSs can be used to improve the damping ratios for the low frequency oscillation modes.
