Parameter Estimation of Induction Generators Model

The resistance of one stator winding is estimated based on its length, cross-sec­tional area, and conductivity. The coil length is partially in the slots and partially in the end region. Thus, the resistance may be estimated and is the basis for estimating the stator resistance. The squirrel-cage rotor resistance is determined by adding the contributions […]

Floater-Rotor Passive and Active Decoupling Control

The major technical challenge of installing an offshore wind turbine is related to minimizing the wave-induced motion of the turbine rotor and understanding the coupling between support structure and the wind turbine, while achieving exceptional static and dynamic stability. Standard control algorithms for variable blade pitch turbines aimed at MPPT in a variable wind will […]

Control-Oriented Modelling and Dynamics

Fuel cells need to be properly controlled during both the transient – and steady-state operations for optimum performance efficiency and long life. If not properly controlled, the cell efficiency will fall significantly during transient operations and the cell’s useful life will be reduced drastically. The efficiency of the fuel cell is highly dependent on the […]

Characteristics of Induction Generators and Experimental Determination of Parameters

The fundamental performance characteristics of induction generators are plots of variations of the generator current with a control parameter such as the conduction angle of the IGBT-type controller. The current decreases by decreasing the con­duction angle while increasing the rotor speed increases the current. Another important characteristic is the harmonic factor in the generator current […]
