摘要: | 首先,本文回顧了我國離岸風場發展的現況與未來規劃,並採用短路比為指 標分析了大量離岸風場併網後系統可能面臨的潛在問題。接著本文以彰濱離岸風 場為例,利用 Matlab/Simulink 模擬軟體,參考民國 117 年台電電網數據建置研究 系統,透過模擬各故障,分析了不同短路比對系統穩定性的影響。結果與推論一 致,隨著風場併網量逐年上升,短路比逐漸下降,將導致系統電壓穩定性降低以 及故障後的過電壓峰值逐年加劇。
為了解決這一問題,本文提出改良的 STATCOM 動態電壓追蹤控制策略,通 過外部設置期望電壓響應作為動態參考值,再利用 PSO 演算法找尋最佳控制參數。 模擬結果顯示,與傳統控制器相比,所提出的 STATCOM 動態電壓追蹤控制器能 使 STATCOM 發揮更快且更優的補償能力,增加併網點在面對大型故障時的安全 裕度。 This thesis first reviews the current status and future planning of offshore wind farm development in Taiwan, using the short circuit ratio (SCR) as an indicator to analyze the potential issues that may arise from the large-scale grid integration of offshore wind farms. Using the Changbin Offshore Wind Farm as a case study, the research system was constructed with Matlab/Simulink simulation software, referencing Taipower grid data from 2028. Various incidents were simulated to analyze the impact of different SCRs on system stability. The results align with the hypothesis that as wind farm grid integration increases annually, the SCR decreases, leading to reduced voltage stability and increased post-fault overvoltage. To address this issue, this thesis proposes an improved STATCOM dynamic voltage tracking control strategy, which sets an expected voltage response as a dynamic reference value and uses the PSO algorithm to find the optimal control parameters. Simulation results show that compared to traditional controllers, the proposed STATCOM dynamic voltage tracking controller enables STATCOM to provide faster and more efficient compensation, thereby increasing the safety margin of grid connection points during major faults. |
