本文旨在設計及製作自激式感應發電機之功率控制系統。本系統採用交流-直流-交流轉換器組成功率轉換器,利用脈波寬度調變技術及數位訊號處理器的整合控制,將變動電壓及頻率之發電機電源轉換為固定電壓及頻率之電源供應獨立負載。直流-交流轉換器將採用電壓源換流器,使用電壓控制模式將儲存直流電容器電壓轉換為固定電壓及定頻的平衡三相電源。
本文模擬採用三相a-b-c模型方式,結合三相感應電機及交流-直流-交流轉換器,推導三相開關型數學模式來完成動態方程式。本文系統之控制部分是使用TMS320F240數位訊號處理器來完成,完成了2.2 kW能量轉換系統之實體製作,由模擬與實測結果互相比較,以驗證本文所提轉換系統之可能性。
This thesis presents the results of design, implementation, and simulation of an autonomous self-excited induction generator (SEIG) feeding an isolated load through the employment of power converters (rectifier and inverter). The DC-to-AC inverter employs pulse-width-modulated (PWM) technique and a TMS320F240 digital signal processor (DSP) to convert variable-voltage and variable-frequency voltage generated from the SEIG to a three-phase constant-voltage and constant frequency voltage source.
The three-phase induction machine model based on an a-b-c reference frame is employed to simulate the performance of the SEIG connected to the power converters and loads. An experimental prototype with a 2.2 kW induction machine driven by a brushless DC machine (BLDC) is to demonstrate the performance of the proposed control scheme. Both simulated and experimental results of the studied system under different values of loading resistance and rotor speed are accomplished and compared in detail.
It can be concluded from the simulated and experimental results that the proposed power converters with adequate control scheme can effectively improve the performance of output voltage of the studied SEIG under various rotor speeds and loading conditions.
