臺灣博碩士論文加值系統

隨著高科技產業的蓬勃發展，電力品質要求也愈來愈嚴格，而當系統發生電力擾動現象時例如：電壓驟降、電壓突昇、電壓閃爍、負載閃爍及三相電壓不平衡時，如何維持電力系統穩定持續運轉，以供應可靠的電力給用戶，是當今研究的重要課題。
本論文旨在分析及模擬靜態同步補償器，當電源正常供電時，可藉由變流器執行改善電源側之功率因數、消除電流諧波及對電容器充電之功能，而當系統發生電力擾動現象時，可將電容器之電力經由變流器傳送系統。
最後為了驗證本論文之可行性，將以模擬軟體Matlab/Simulink來進行模擬分析，以驗證本論文所提出之可行性。

With the rapid development of the Hi-Tech industry, the power quality is more and more important. When the electric perturbation phenomenon such as: voltage sag, voltage swell, voltage flicker ,load flicker and unbalance three-phases voltages is happen, the power system should be operated to supply users with stable and reliable electricity.
The system analysis and control scheme of static synchronous compensator are presented in the thesis, When the utility system is in the normal condition, the compensator is operated to improve the power factor at the source side. When the electric perturbation phenomenon is happen, the compensator can compensate the reactive power in order to obtain the constant RMS value at the load side.
In order to verify the feasibility of the control scheme proposed in this thesis, the software package MATLAB/SIMULINK is used to obtain the simulated waveforms.
