This paper presents an improved stator flux oriented (SFO) control system for a stand-alone induction generator. The induction generator supplies a variable resistive dc load. In order to provide an essentially constant terminal voltage, the product of the rotor speed and the stator flux reference should remain constant. However, in this case the control system is not able to function properly at different loads and dc-link voltages. In this paper, we introduce a new algorithm in which this product is constant at certain dc-load and dc-link voltage references. The dependence of the stator flux reference on the dc load and dc voltage reference is mapped using an artificial neural network (ANN). We also present an analysis of the efficiency of the SFO control system, as well as its performance during transients, over a wide range of both dc-link voltage references and loads. The validity of the proposed approach is verified by realistic simulation in a Matlab-Simulink environment.

“…Once an induction generator is excited, the capacitor maintains the excitation. The minimum dc capacitance required for the initiation of voltage buildup can be found in reference [6]. For a given capacitance, self-excitation can only be achieved and maintained over certain load and speed ranges.…”

“…A basic analysis dealing with the voltage build up of a simple control method using only the DC bus voltage of the power converter as control variable was already given by [1] but without any controller design guidelines. The grid connection of an induction generator via a back-to-back converter topology is the most common application [2], [3] also in this context as it offers the highest degree of freedom for a maximum power point tracking for example.…”

With increasing rare earth prices and the claim for cost effectiveness of electrical drive trains especially induction generator solutions might turn into focus as preferable alternative to permanent magnet synchronous generators, even in spite of the lower power density. But an induction generator requires reactive power either provided by capacitors or by a self commutated power converter to ensure excitation. This article gives profound information on the fundamentals of the steady state operation of an induction machine operated by a voltage source power converter, VSC. Based on these fundamentals a very simple control law for the DC bus voltage of a power converter operated as active rectifier is proposed and validated by experiment. No vector calculus is needed and as it only requires the speed information (no current measurement is needed) this method can be considered as a contribution to robust drive control / condition monitoring with a common field oriented current control method possibly running in parallel.

“…Stand-alone IG can operate in the self-excited mode only when excitation power is supplied from an external source. This reactive power can be supplied by a variety of methods, ranging from a simple bank of capacitors [1][2][3][4][5] to inverters with complex power conversion techniques [6][7][8][9]. The well-known advantages of IG are their low cost, robustness, brush-less cage rotor construction, absence of separate D.C. source, inherent overload protection and ease of maintenance.…”

-In this paper, a simple control strategy for maximum power extraction from stand-alone wind energy conversion system using induction generator under variable speed and load conditions is proposed. This is achieved by varying the inverter frequency and modulation index depending upon the changes in load at the IG terminal. The proposed method eliminates the need of a speed encoder, and hence it's an attractive sensor-less control method. The developed model is simulated in MATLAB/SIMULINK. The simulation results are presented to validate the developed control strategy. The control algorithm is implemented on TMS320F243 DSP. Experimental results closely resemble the simulated results.
