摘要

不斷電系統、整流器、變頻器等之非線性負載在現代化工廠中已是不可或缺之設備，但其衍生之電力諧波問題，卻常常使得設備誤動作，電力電容器燒毀，造成工廠之重大損失。
本文依據電力諧波理論，使用電力品質分析儀，實際量測各電氣室之負載配電盤，利用實測得知之諧波電流，透過EDSA軟體加以分析，可提供工廠之電力系統操作及維護人員，推算出配電系統中可能發生之諧波問題點，進而避免電力諧波在系統中之危害，以防止事故之發生。
為改善電力品質，本文說明將所設計之被動式濾波器投入於主匯流排，用以降低系統之總電壓諧波失真率與提升系統功率因數，其作法既可節省設備成本，亦可改善電力系統之諧波問題。

Nonlinear loads, including the un-interruptible power supply and converter, etc, are essential equipments in the modern factories. However, these nonlinear loads may likely lead to facility malfunction and capacitor damage. The harmonics from the nonlinear loads cause severely unexpected loss.
This thesis in accordance with power harmonic theory addresses using harmonic analyzer and measuring the load power panel of electrical rooms. The harmonic currents were measured in order to analyze the harmonic voltages of the distribution system with EDSA software. With the simulation results, the harmonic problems for the power system are expected to be remedied and prevented.
For improving the power quality, the passive filter, which is on the main bus, is designed not only for decreasing the harmonic distortion of the voltages but also for improving the power factor of the power system. Furthermore, the method can reduce the installation cost and remedy the harmonic problems of the power system.
