Abstract:

Power quality is one of the major concerns of the present era. One of the main power quality issues is the voltage sag during power transmission. To solve this problem custom power devices have been introduced. One of these devices is the Dynamic Voltage Restorer (DVR), which is considered to be the most efficient and effective modern custom power device used in power distribution network. Its advantages include fast dynamic response, large variation in the type of sags to be mitigated and variation in the type of the connected load. A dynamic Voltage Restorer basic configuration consists of an energy storage cell, a voltage source inverter, filter and a step up voltage injection transformer to boost the magnitude of voltage during voltage sag conditions. In this paper a novel configuration of cascaded h bridge multilevel inverter which uses reduced number of power semiconductor switches is realized as a dynamic voltage restorer during an event of voltage sag.
