| Abstract | In the last years, the wind power generation incorporated into standard grids has been increased significantly. This situation forced the revision of grid connection code requirements, to guarantee the reliability in systems with high wind power penetration. In case of three phase short circuit, voltage sags are observed near the point of failure, and characterized by a sudden voltage reduction and lagging phase jump. For induction generator based wind farms connected to weak grids, such sag may lead to wind farm outage, due to limited low voltage ride through capability of induction generators. In this work a voltage sag compensation strategy is proposed for amplitude and phase jump restoration, and compared with amplitude only compensation strategy. These strategies were implemented using an Unified Power Quality Compensator UPQC. Unlike other Custom Power Devices like DVR and D-Statcom, the UPQC has the feature of active power sharing between shunt and series converters through DC-link; thus, series voltage injection with any phase angle may be maintained without the need of power source installed in DC bus. Results shows a better wind farm performance in proposed strategy than that found in magnitude only compensation schemes. Thus, considering the improvement in performance, the proposed strategy is recommended in retrofitting the existing installed fixed speed induction generators based wind farms. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
