DSTATCOM Performance for Voltage Sag swell Mitigation
International Journal of Recent Technology and Engineering (IJRTE), 2020 The Indian economy has been growing at a fast pace since the beginning of this millennium. Due to constraints in the availability of fuel and environmental concerns, the power generation sector has not kept pace with other industrial sectors. One way of increasing the power availability is by reducing the high losses in the existing power transmission ...
