| Abstract | This paper presents the design and implementation of a power control system for variable-speed, permanent-magnet synchronous generators. In this system, a three-phase, full-bridge rectifier and a single-phase, three-level inverter are proposed to convert the three-phase varying voltage and frequency generated by wind to single-phase source with constant voltage and frequency. Specifically, the output power of the overall system is adjusted by detecting the dc-link voltage as well as output voltage and current of inverter. A novel three-level dc/dc power converter is designed to charge and discharge the battery set, while fixed- voltage control method is used to supply load power when wind speed is low. The single-phase, three-level inverter operated under voltage-controlled mode by using new two-axis amplitude-lock- loop technique algorithm can provide a single-phase source with fast response, stable and low harmonic distortion power to load. The performance of the system is simulated by Matlab/Simulink. Then, a low-cost, 16-bit digital signal processor (DSP, TMS320LF2407A) is used to implement the control functions of the generation system. The experimental results for a 750 W generation system show that the output voltage and frequency can be held at 110/220 V and 60 Hz, respectively, when the speed varies from 200 to 450 rpm. The feasibility of the generation system is verified experimentally. |

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.
