“…The total losses of IEGTs are very low, even lower than those of thyristors. IEGTs have been usually fabricated without a short circuit protection capability, but IEGTs with current sensing and short circuit protection capability have also been manufactured 5. The maximum rated power of commercial IEGTs is relatively higher than that of IGBTs, i.e.…”

This paper investigates the possibilities of viable power electronics converters, semiconductor switching devices and electric machines for 10 MW variable-speed wind turbine generators. The maximum rated power of existing wind turbine confi gurations is in the range of 6 MW. The proposed alternatives are compared against several technical and economical factors, and their advantages over the present wind turbines are highlighted. A comprehensive performance comparison of modern power semiconductor devices, their electrical characteristics and the key differentiators among them are presented. The power electronics converters considered include all commercially available multilevel voltage source and current source converters as well as the opportunities offered by power electronics building block-based design. The factors used for the comparison include the converter power range, capacitor voltage balancing, common mode voltage and current, electromagnetic interference emissions, fault ride-through capability, reliability, footprint, harmonic performance, effi ciency and losses, component count, risk of torsional vibration by the harmonics and inter-harmonics, complexity, ease of back-to-back operation and fi ltering requirements. For the electric machines, this study concentrates on high-temperature superconducting machines, multi-phase induction machines and permanent magnet synchronous machines. These machines are compared against existing wind generator technologies in terms of their power range, torque density, effi ciency, fault ride-through capability, reliability, footprint, harmonic performance, ease of fault detection, excitation control, noise and vibration signature, oscillation damping, gearbox requirement, cost and the size of the associated converter.Converter and generator candidate assessment for 10 MW wind turbines B. Badrzadeh 426This paper evaluates the viable and reliable alternatives for high-power wind turbines for very large wind farms. For the assessment, a rated power of 10 MW per turbine is assumed. The alternatives considered are already available in the marketplace (high-power converters and electric machines in this power range have been used in applications such as oil and gas, marine propulsion and utility grid for many years), or are being commercialized for the required power range. Options such as switched reluctance machines, resonant converters and matrix converters are not therefore considered as they are not available in the market for MW range applications.Modern power semiconductor devices including gate turn-off thyristors (GTOs), insulated gate bipolar transistors (IGBTs), insulated gate commutated thyristors (IGCTs), injection enhanced gate transistors (IEGTs), symmetrical gate commutated thyristors (SGCTs) and their electrical characteristics are discussed. A comprehensive performance comparison of these devices in terms of the device rating, switching frequency, gate driver circuit requirements, failure mode, cooling methods and device over-voltage and over-current pro...
