碩士 === 中原大學 === 電機工程研究所 === 91 === Abstract Nonlinear loads, including the un-interruptible power supply and converter, etc, are essential equipments in the modern factories. However, these nonlinear loads lead to facility malfunction and capacitor damage. The harmonics cause severely unexpected loss. This thesis is based on the load measurement to establish the Y- matrix of the factorial power system, and then calculates the corresponding Z matrix. The thesis uses the harmonic current measured from the power system to simulate the harmonic voltage distribution of the system with different filters, in order to find the most appropriate filter design, which tends to prevent the system from the resonance. In order to attain the optimal filter design for the system, the proposed method and the result of this thesis might provide useful references and approaches to deal with incidents for engineers.
