The Impact of Synchronous Generator on Voltage Sag Mitigation in Power System Network

Power quality (PQ) has become a major concern in recent years. In order to maintain the proper PQ, it is important to detect the PQ problems through fault analysis and investigate for an adequate way to overcome the problems. Sag, which is a sudden decrease in voltage level, is the most common one in PQ problems almost covering 56% of the entire PQ problems. Therefore, mitigation of voltage sag has drawn much attention. This paper represents the effectiveness of synchronous generator in investigation of Voltage Sag Mitigation in Distribution Network. The selected system for this work is the IEEE 14 bus network. The simulation was carried out using MATLAB software. Two possible scenarios, when sag occurrence and the generator connection bus are same and when sag happens near one bus and the synchronous generator is connected to another bus are taken into consideration for simulation analysis.
