چکیده
The wind energy conversion system (WECS) differs from other power systems. It is clean and pollution free. But the output of wind power plant is fluctuated in nature. It depends on the wind speed. The nature of wind is variable. The variable wind generates fluctuated power. Fluctuated output is the major problem of wind power plant. This problem can be solved by using convertor units. The second problem of wind power plant is different types of fault occurring in wind power plants, like line fault and grid fault etc. This paper discusses the fault in wind power plant or fault analysis in DFIG system, using D-STATCOM. The DSATCOM is a shunt device which is used to solve fault problem in distribution system. These papers discuss the analysis and output characteristics of doubly feed induction generator (DFIG) due to the normal and abnormal condition. This paper has presented the power quality problems such as voltage dips, swells and interruptions, and mitigation techniques of custom power electronic device D-STATCOM. This device is used for controlling the voltage fluctuation, flicker reduction and to maintain voltage stability.
