Popis: | The analysis of a step-up transformer tap change on the quantities at the point of connection to the transmission grid is presented in this paper. The point of connection of generator TENT A6 has been analyzed, and a detailed model of this generator is available in software package DIgSILENT Power Factory. The comparison between the effect of a step-up transformer tap change on the quantities at the point of connection during automatic and manual operation of voltage regulator has been conducted. In order to conduct the analysis of the manual operation of the voltage regulator, the comparison between the different methods of modeling of these modes has been performed. Several generator operating points, selected in order to represent the need for tap change, have been analyzed. Also, previously mentioned analyses have been performed taking into account the voltage-reactive stiffness at the point of connection. |
