| Popis: | 94 The purpose of this study was to analyze the transient phenomena of transmission lines and towers with and without line arresters caused by lightning strokes, through which the specifications of structure design were modified in order to improve the reliability of power transmission. From this premise, by using ATP Draw model, three power configuration modes of the 345kv overhead transmission lines and towers were simulated and analyzed: (1) The four phases JMarti transmission line module (applied to overhead transmission lines with shields) joined the single phase distributive parameters Z module (used to simulate the field conditions of towers). (2) The single phase JMarti simulated for shield lines joined the single phase distributive parameters Z module for tower, and the three phases distributive parameters Z-T module for overhead transmission lines without shields. (3) The single phase distributive parameters Z module simulated for shield lines and towers joined the three phase distributive parameters Z-T modules for overhead transmission lines. In addition, the researcher sought to reply to other relevant modes set out in the literature to evaluate the present simulated conditions by way ofATP Draw. The results provided some evidence of the effectiveness of the aforementioned three modes. |
