Feasibility Analysis on High Voltage Ride-through of Wind Turbines

Abstract:

With the rapid increase of wind farms, a set of specific requirements have been established or are developing. The objective of these grid guidelines is to ensure wind farms not adversely affecting the power system. The control strategies and theories on low voltage ride through (LVRT) have been focused on for a long time, how to deal with the gird high voltage is seldom discussed. This paper introduces the main types of wind turbines, discusses the major grid requirements of high voltage ride through (HVRT). The capability of HVRT for current wind farms is introduced. The technology and its implementation of the HVRT of wind turbines are focused on. The technical feasibility to increase the capacity of HVRT for wind turbines and the cost are analyzed in detail. Finally a conclusion is achieved, that is installing DC chopper can help converters to realize HVRT.
