   Comparison of Fault Ride-Through Strategies for Wind Turbines with DFIM Generators
By DITTRICH Andreas; STOEV Alexander [View]
[Download]

Abstract: Regenerative energy systems are confronted with increasing demands for power quality and fail-safe operation at grid voltage failures. Grid codes currently demand for fault ride-through (FRT) capability up to 15\% retaining voltage and support of the grid voltage by supplying reactive current until fault clearance. The paper discusses and compares different FRT strategies, their capabilities to fulfill the codes and their impact on turbine performance.

   Experiences on voltage dip ride through factory testing of synchronous and doubly fed generator drives
By NIIRANEN Jouko [View]
[Download]

Abstract: The electrical utilities have specified in their recent requirements that wind turbines have to be capable to ride through severe voltage dips without disconnecting. For the verification of the ride through capability factory and field tests are needed. In most cases a test system with fault emulation is used that will give more realistic results especially for generators that have their stator directly connected to the grid. However, care has to be taken that the impedance level of the test setup is low enough. Experimental results are presented for a 1.6 MW doubly fed generator and a 200 kW synchronous generator drive. Moreover, the problem with the reactive power measurement during ride through is discussed in the end of the paper.

   Permanent Magnet Synchronous Generators for Regenerative Energy Conversion - A Survey
By SCHNEIDER Tobias; BINDER AndreAs [View]
[Download]

Abstract: A survey on recently installed or developed permanent magnet (PM) synchronous generators for energy conversion in regenerative and alternative power supply systems is given. Its focus is for low speed machines on geared and gearless PM generator systems for wind power plants and small PM hydro generators in gearless coupling. For distributed co-generation of heat and electrical power by micro gas turbines specially designed PM generators for high speed are necessary. Design example for both low speed wind and hydro generators and high speed generators are given along with application examples.
