“…The three induction generators are rated at 3.6 kW. The relationship between magnetizing inductance (L m ) and phase voltage for induction machine was obtained experimentally by [22]: The proposed system starts excitation process from capacitors bank of 60 lF which are connected across the stator terminals of an induction machine. The global system is tested during 8 s, and the three generators are subjected to step change in the rotor speed as shown in Fig.…”

This paper deals with standalone small power generation employing three self-excited induction generators under varying speeds feeding an isolated load. The proposed system utilizes three-level cascaded H-bridge inverter for the three generators. The control scheme has the capability of regulating the output voltage for balanced operation of a three-phase isolated load under variable speed. The proposed control can be implemented using DSPACE 1104, and the experimental results are presented to demonstrate the effectiveness of the proposed controller for an isolated generating system.

“…Even when the capacitor is properly chosen, additional mechanisms must be added to avoid demagnetization and to achieve better control of the voltage produced. Some of these mechanisms include field-oriented techniques [7][8][9][10][11]. Contemporary research focuses on control mechanisms using stator flux orientation as well as those using rotor flux orientation.…”

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.

“…Early studies have concentrated on ways of sizing, matching and adapting wind turbine generator pumping systems since a proper match between the installed capacities with the insolated load is essential to optimize such installations. Various studies have been done on the choice of the drive system, which suits wind turbine source, types of pumps to use and ways to control and optimize the whole system [4,5]. This was firmly related to the existing technologies.…”

An improved efficiency of fuzzy sliding mode control of permanent magnet synchronous motor for wind turbine generator pumping system

et al. 2012

Abstract-This paper presents an analysis by which the dynamic performances of a permanent magnet synchronous motor (PMSM) motor is controlled through a hysteresis current loop and an outer speed loop with different controllers. The dynamics of the wind turbine pumping drive system with (PI) and a fuzzy sliding mode (FSM) speed controllers are presented. In order to optimize the overall system efficiency, a maximum power point tracker is also used. Simulation is carried out by formatting the mathematical model for wind turbine generator, motor and pump load. The results for such complicated and nonlinear system, with fuzzy sliding mode speed controller show improvement in transient response of the PMSM drive over conventional PI. The effectiveness of the FSM controller is also demonstrated.
