低轉速黑潮發電機及其系統模擬

Abstract

本論文重點於設計150轉輸出400W之永磁發電機與洋流發電系統的控制，並且開發部分黑潮先導實驗機組來測試發電機效能、電壓、電流、轉矩與功率等。測量結果在150轉最多可以達到540W。另一方面利用MATLAB進行發電機的設計，開發出電磁設計程式，完成了發電機側控制、系統側控制與調變技術，利用SimPowerSystems工具箱模擬整個動態系統，SimPowerSystems工具箱可以提供快速且精確的結果，實現了最大功率追蹤、向量控制、空間向量調變技術，並於最後整合成一部完整黑潮發電系統，達到輸出功率400W，電壓頻率1pu、電壓大小1pu。

The goal of this study is to design a 400W low speed(150RPM) permanent magnet generator and develop a control system for a marine current energy power system. We have developed some equipment to test the efficiency of the generator , voltage, current, torque and power. Measurement results of the generator can be up to 540W on the 150 rpm. Additionally, design a permanent magnet generator and the power generation system for Kuroshio by the MATLAB programs. We also utilize MATLAB to implement, electromagnetic design program, generator-side control, grid-side control and modulation techniques. We simulate the dynamic system used by SimPowerSystems toolbox, which can quickly and accurately shows the simulation results. It has implemented the maximum power point tracking, vector control and space vector pulse width modulation(PWM) into the power generation. Finally, we integrate each part into a complete low speed power generation system to output 400w , voltage frequency 1pu, voltage magnitude 1pu for Kuroshio.
