本文係研究採用串聯向量補償器於抑制含有蒸汽渦輪機以及風場系統之次同步共振。文中第一個研究系統係以雙饋式感應發電機與動態滑差式感應發電機風場取代美國電機電子工程師學會次同步共振之第一標準模型的傳統同步發電機；文中第二個研究系統係為整合動態滑差式感應發電機之陸域風場與雙饋式感應發電機之離岸風場經串聯補償電容器連接至台電簡化系統。文中於三相平衡系統下利用交直軸等效電路模型，分別建立同步發電機、雙饋式感應發電機為主與動態滑差式感應發電機為主之風場以及串聯向量補償器等模型，並利用極點安置法設計串聯向量補償器之比例-積分-微分阻尼控制器。在穩態特性方面，針對不同的線路串聯補償比及風場在不同平均風速下進行特徵值分析；在動態模擬方面，完成風場在風速變動以及線路補償比變動等時域模擬。由穩態及動態等模擬結果得知，當系統加入串聯向量補償器結合比例-積分-微分阻尼控制器後，能有效抑制所研究系統之次同步共振。

This thesis presents the suppression of subsynchronous resonance (SSR) occurred in power systems with steam-turbine systems and wind farm systems using a series vectorial compensator (SVeC). The first studied system employs a dynamic slip induction generator (DSIG)-based wind farm and a doubly-fed induction generator (DFIG)-based wind farm to replace the synchronous generator (SG) in the IEEE First Benchmark Model. The second studied system integrates both DFIG-based wind farm and DSIG-based wind farm to feed to the simplified Taipower System through a series-capacitor bank. The d-q axis equivalent-circuit model under three-phase balanced loading conditions is used to establish the complete studied systems. A proportional-integral- derivative (PID) damping controller of the proposed SVeC is designed by using pole-assignment approach based on modal control theory. Eigenvalue analysis of the studied systems under different series compensation ratios and various wind speeds of the wind farms are performed. Time-domain simulations under wind-speed change in wind farms and series compensation level changed in the studied systems are also carried out. The simulation results show the effectiveness of the proposed SVeC with the designed PID damping controller on suppressing SSR of the studied power systems.
