Development of Simulation Model of Single-Phase Circuit Lock in the DiGSILENT PowerFactory Program

EasyChair Preprint 6746

Abstract

The most widespread types of damage in distribution networks are analyzed by a voltage of 6-35 square meters. It is shown that the predominant amount of them form single-phase land closures, which can also cause a stress in the place of damage and negatively affect the electrical equipment, which can lead to a decrease in economic indicators. The methods of increasing the reliability of distribution networks with a voltage of 6-35 square meters are analyzed. The main attention is focused on the method of improving reliability due to the grounding of neutral through an arcane reactor, the main advantage of which in operation is a continued work with a single-phase circuit to land without disconnecting consumers. The simulation model of the distribution network in the mode of single-phase circuit to land is developed and its main parameters are calculated. As a simulation environment, the software complex DiGSILENT PowerFactory is used. A specific example of calculating parameters when using the proposed simulation model in the DiGSILENT PowerFactory program containing 5 air and 5-cable transmission lines of 35 kV and from 10 to 100 kilometers. Using this model will allow you to study transient processes in single-phase ground circuit mode, prevent emergency situations in distribution networks.
