臺灣博碩士論文加值系統

本論文主旨在於研究靜態同步補償器之結構和應用，文中首先探討由多脈波電壓源變流器組構之靜態同步補償器其結構型態，並且分析其輸出電壓、電流波形之特性和諧波含量，再利用MATLAB/Simulink/SimPowerSystems軟體建立STATCOM兩種功率電路與控制電路之詳細模型，此一STATCOM模型倂聯至動態負載變動之兩電力系統上進行模擬，經模擬結果證實靜態同步補償器具有快速虛功補償以及系統電壓調節之功效。

This thesis investigates the structures and application of Static Synchronous Compensator (STATCOM). The different configurations of multipulse VSI based STATCOM are presented firstly, and the waveform characters and harmonic contents of the output voltage and current are analyzed. Then, the detail models of power circuit and control circuit of STATCOM are built by using the MATLAB/Simulink/SimPower
Systems. The complete simulation results of the STATCOM connected
to two power systems with dynamic load excursions are discussed.
It is confirmed that STATCOM has the benefits of high-speed VAR compensation and bus voltage regulation.
