This paper analysis the Dynamic Voltage Restorer response provided for voltage sags mitigation in the electrical distribution networks with connection substation topology. Most often the voltage sags are caused by severe faults on the lines adjacent to main feeder and by faults on main feeder of connection substation. A realistic configuration of the electricity distribution network, similar to the...
This paper presents the Dynamic Voltage Restorer (DVR) response study in cases of voltage sags occurrence in the electrical distribution networks with connection substation topology. Usually, these voltage disturbances are caused by faults that can occur on the lines connected to the same bus bar as the main feeder or even on main feeder of connection substation. A DVR that uses a diode based rectifier...
This paper discusses the performance of a dynamic voltage restorer (DVR) used for improving the voltage quality in medium voltage distribution networks with secondary distribution configuration. The DVR compensator is analyzed as a voltage controller. Modeling of DVR and his control scheme are proposed. Validation of control scheme and DVR model is carried out through simulations by using SimPowerSystem...
