| Popis: | 101 Recently, with the advancement of technology, customers request more high electricity quality. Actually event causes unstable voltage and therefore equipment in the plant operate abnormally and appliances of the customers were damaged. This thesis first discusses several abnormal voltages which include imbalanced voltage, voltage fluctuation, voltage dip and evaluates foreign relative standards. The next step of this thesis applies phase diagram and electric circuit method analyzes and derives equivalent circuit and associated mathematical models as well as evaluates the cause of abnormal voltage for distribution line with out of one-phase. Finally, EMTP/ATP is applied to establish the computer models of overhead and underground of distribution system for computer simulation. Simulation cases which include out of one-phase, neutral line opened, lightning strike and single line ground will be executed to observe voltage variation and analyze the effect of customer load. Simulation results may guide the prevention of customer appliance damage by over voltage. |
