臺灣博碩士論文加值系統

本論文係針對傳統同步發電機與超導同步發電機之特性，提出兩種系統架構，系統架構一為採用傳統同步發電機及超導同步發電機併聯至電網所組成之大規模電力系統；系統架構二為以超導同步發電機為基礎與以雙饋式感應發電機為基礎所組成之混合離岸式風場，連接至含與未含超導同步發電機之三機-九匯流排多機電力系統。本論文於三相平衡系統條件下，採用交直軸等效電路模型以建立完整系統之數學模型，並分別針對超導儲能系統以設計比例-積分-微分及相位超前-落後振盪阻尼控制器，以俾抑制電力系統之低頻振盪，最後加入超導故障限流器以改善其暫態特性。本論文於穩態分析方面，分析同步發電機在不同工作條件、風速變動以及海底電纜長度變動等情況下，對系統穩定度特性造成之影響；於暫態及動態方面，則分析轉矩干擾、風速變動及三相短路等模擬結果，並比較系統加入超導故障限流器及阻尼控制器前後所改善之穩定度。

This thesis presents stability analysis results of two system configurations using a conventional synchronous generator (SG) and a superconducting synchronous generator (SCSG). System configuration 1 is a large-scale power system consisting of an SG and an SCSG connected to power grid. System configuration 2 is a three-generator nine-bus multi-machine power system while one of the three SGs is replaced by an SCSG and an integrated SCSG-based and doubly-fed induction generator (DFIG)-based hybrid offshore wind farm (OWF) is connected to the system. The q-d axis equivalent-circuit model is derived to establish the complete system model under three-phase balanced condition. The designed proportional-integral-derivative (PID) and the lead-lag oscillation damping controllers (ODC) of superconducting magnetic energy storage (SMES) unit to damp low-frequency oscillations of the studied systems with a superconducting fault-current limiter (SFCL) are carried out. Steady-state characteristics of the studied systems under various operating conditions of the SG, the SCSG, wind speed, and length of lines are performed. Dynamic and transient simulations of the studied systems subjected to a wind-speed disturbance, a torque disturbance, and a three-phase short-circuit fault at the studied power systems with and without the SFCL and the designed ODC are also compared.
