具LVRT功能之三相市電換流器運用於直流微電網模擬測試平台

LVRT Capability Implementation of Three-Phase Grid-Connected Inverter on DC Micro-Grid Test Bed

指導教授 : 劉志文

摘要


本文主旨在建立具市電併聯功能的直流微電網模擬測試平台,該系統包含了風力發電機、太陽能光電板與燃料電池等分散式能源,鋰離子電池、超級電容等儲能元件,以及三相市電換流器。 三相市電換流器具備了LVRT(Low Voltage Ride Through)的能力,LVRT的能力能讓分散式電源(微電網)於電力系統故障,導致電壓跌落的期間,分散式電源(微電網)仍能正常運轉。 此模擬測試平台以數學模式描述各分散式電源及儲能元件特性,以軟體Matlab/Simulink建立等效模型,並以軟體LabVIEW建立人機介面,讓使用者能透過畫面清楚掌握分散式電源及儲能元件狀態。

並列摘要


The object of this thesis is to present a DC micro-grid simulation test bed with grid-connected function which consists of wind turbines, photovoltaic (PV) panels and fuel cells as distributed generations, lithium-ion batteries and ultra-capacitors as energy storages, and a three-phase grid-connected inverter. The three-phase grid-connected inverter is equipped with the LVRT (Low Voltage Ride Through) capability which lets the micro-grid be able to ride through grid faults that bring voltages down to a very low level. This test bed is built by mathematical models in Matlab/Simulink, and the simulation results are showed by human-machine interface in LabVIEW. It is a platform for users to clearly handle the information of the DC micro-grid.
