Studies on a Hybrid Wind Turbine Generating System Using a Current‐Source Thyristor Inverter

“…is removed and the SG is operated as a synchronous compensator, the system becomes the current‐source thyristor inverter wind turbine generating system discussed in Ref. . Hence, an equivalent circuit, for use in the characteristics analysis of the system, a dynamic model, and so on, can be derived on the basis of Ref.…”

“…Thus in this hybrid wind generator system, the synchronous compensator, which is one of the main components of the thyristor inverter type wind generator system in Ref. , can supply active power when the synchronous machine is driven by the PM, and in this case the machine is operated as an SG. When the PM has the capability to maintain its rotational speed constant, the output fluctuations of the wind generator can always be compensated by the SG, obtaining arbitrary system outputs in spite of changes in the load or wind velocity.…”

“…Thus, a practical‐scale tested hybrid system was constructed, in which the synchronous compensator SC of the thyristor inverter wind turbine generator system with a 40‐kW wind generator system (a SUBARU 15/40 wind generator system) that was described in Ref. was used as an SG. In this case, the SG was driven by an induction motor, supplied from an adjustable voltage and adjustable frequency inverter, as a PM.…”

“…In this paper, a novel hybrid wind turbine generating system which can resolve these issues is proposed . This system is based on a DC‐link wind turbine generating system using a current‐source thyristor inverter , and it has many attractive features such as high reliability and high quality of electric output.…”
