市電併聯型太陽光電發電系統性能評估及驗證

本論文旨在探討固定型及單軸追日型太陽光電(photovoltaic, PV)系統發電量之差異、不同串列數於變流器相同最大功率追蹤控制下PV 系統最大功率追蹤的啟動特性及中南部地區PV 系統傾斜角之最佳化設計。本文分別以本校電資學院頂樓冷媒驅動式追日型1.14kWp、固定型1.14kWp、HIT1.0kWp、HIT1.2kWp、屏東縣墾丁21.94kWp、屏東縣麟洛10.08kWp、彰化縣二水18.24kWp 共七套PV 系統為標的，先以Solar Pro 套裝軟體模擬，再與監測數據比對驗證，分析結果顯示單軸追日型PV 系統比固定型PV 系統其發電量多出1.145 倍；不同串列相同最大功率追蹤控制下，其直流端輸入功率將影響最大功率追蹤的啟動時機；而台灣彰化地區PV 系統其傾斜角最佳化角度為19.3 度，台灣屏東地區PV 系統其傾斜角最佳化角度為18.9 度。本文以Solar Pro 套裝軟體分析上述7 套PV 系統之發電量、I-V 曲線、遮蔭影響及發電系統之性能，並將模擬結果與監測數據作比對，作為模擬程式參數修正、PV系統建置及性能評估之參考。

This thesis aims to explore the differences generation power of fixed type and single-axis tracking type photovoltaic (PV) system, different serial numbers of the PV system starting characteristics under the same maximum power point tracking control and south and central of Taiwan the optimal tilt angle design for PV system installation. In this thesis, respectively College of Electrical Engineering & Computer Science of Chien Hsin University top floor refrigerant driven tracking type 1.14kWp,fixed type 1.14kWp, HIT 1.0kWp, HIT 1.2kWp, Kenting, Pingtung County 21.94kWp, Linluo, Pingtung County 10.08kWp, and Ershui, Changhua County 18.24 kWp all seven sets PV systems was the subject for the study. First, the Solar Pro software package was used for PV system simulation, and then compared with monitoring data. The verify and analysis results showed that the tracking type PV system generating power than Fixed PV system 1.145 times more electricity. The different serial numbers of the PV system under the same maximum power point tracking control, the DC input power will affect the start time to the maximum power point tracking. At Taiwan's Changhua PV system, the tilt angle optimized is 19.3 degrees, while Taiwan's Pingtung PV systems, its tilt angle optimized is 18.9 degrees. In this thesis, the Solar Pro software package was used to analyze the generating capacity, IV curves, shading impact and performance of power generation systems of the seven sets PV systems. The simulation results then compared with monitoring data for correcting simulation program parameters, future PV system planning and performance evaluation of photovoltaic generation system.
