摘要

本研究的目的是通过识别和提供每种干扰的规格来清楚地分析。主要目标是研究供电线路突然发生的故障，以及负荷特别是工业中常用负荷所产生的有害影响的调查。仿真结果说明了对配电网中这些干扰的分析。在单相接地故障模型中，电压跌落持续时间为90 ms, Va、Vb和Vc分别为0 kV、30.97 kV和30.98 kV。对于相-相故障模型，持续时间约为85 ms, Va = 21.3 kV, Vb=Vc= 0kV。当使用非线性负载时，得到的总需求失真(TDD)在32.10% ~ 44.32%之间，总需求失真(TDD)在91.42% ~ 95.21%之间。

Analysis of Electrical Power Disturbances in Distribution and Industrial Systems

The objective of this study is to clearly analyse by identifying and providing specifications on each disturbance. The main targets are the study of faults that suddenly happen on wires which supply loads, and the survey of detrimental effect coming from the load especially common loads used in industries. Simulation results were presented to illustrate analysis of these disturbances on a Distribution Line network. For signle-phase earthing fault model, the results show the duration of the voltage sag of 90 ms with the magnitudes of 0 kV, 30.97 kV and 30.98 kV respectively for Va, Vb and Vc. For phase to phase fault model, the duration is around 85 ms with Va = 21.3 kV and Vb=Vc= 0kV. When using non-linear loads, the obtained THD varies from 32.10 % to 44.32 % and the total demand distortion (TDD) from 91.42% to 95.21 %.
