   Minimum DC Link Voltage Operation of Network Bridge Converter of a Wind Turbine with Fully Rated Converters (Paper)
By U.I. Dayaratne; J. Knight; S.B. Tennakoon; N.Y.A. Shammas [View]
[Download]

Abstract: Fully rated converter based wind turbines are typically operated with a fixed DC link voltage which is higher than the minimum required at majority of operating conditions. This paper presents a theoretical study determining the minimum DC link voltages required at various steady state operating conditions supported by simulation results.

   Slow speed double fed induction generator (Paper)
By Guntis Dilevs [View]
[Download]

Abstract: This paper concerns the design, magnetic field analysis and generated power calculation of the slow speed induction generator with a three phase secondary winding. All the windings of this generator are placed in the slots of the stator. The rotor is tooth-like and without windings on it. The magnetic field analysis was done to calculate the parameters of the equivalent circuit diagram.

   TRV Studies to determine the Impact of an Offshore Wind Farm on a 132kV Distribution Network (Paper)
By M. Jones; O. Nanka-Bruce; S. Nurse; V. Levi [View]
[Download]

Abstract: Wind farms of the current generation are connected to existing distribution systems onshore. The substantial submarine cable systems that are required raise concerns of a large net capacitive charge, particularly under low export conditions. For an offshore wind farm connection, it is therefore important for the Distribution Network Operators (DNOs) to ensure that the circuit breakers installed at and near the DNOâ€Ÿs point of common coupling (PCC) are fit for purpose with respect to switching operations and fault clearance duty. This paper summarizes the results of transient recovery voltage (TRV) studies carried out for a 60MW offshore wind farm connection to assess the capability of circuit breakers at the PCC and at neighbouring DNO system locations. The proposed circuit breakers are assessed against reference TRVs specified in IEC 62271-100:2001 to assess fitness for purpose.
