“…As compared to the synchronous generator in a SEIG; brushless and rugged construction and capability to generate power at varying speed and which mean substantial increase in the efficiency. Table 1 shows the comparison of SEIG with other generators used in WESs on the basis various parameters [2][3][4][5][6][7][8][9][10][11]. Table 1 clearly describe SEIG that it could be the better option for low/medium speed applications in future and specially in WESs by considering all the parameters.…”

In this paper, a mathematical model of the Self-Excited Induction Generator (SEIG) is developed to analyze the operation of it in wind energy systems. In such type of wind scheme often whole generating system is isolated from the grid and supply electricity to the remote communities. A wind energy system usually a low/medium speed projects driven by controlled/uncontrolled micro wind turbines. The single point operation of these generators is realized; in such a manner that speeds, voltage, currents of generators remain constant under various operating loads conditions. The Electronic Load Controller (ELC) is modeled here for the controlled operation of WES against various load condition. Here the proposed electrical system are modeled and simulated in MATLAB using Simulink and Sim Power System (SPS) set toolboxes and different aspects of the proposed system are studied. On the basis this model different characteristics of SEIG with ELC are analyzed which shows its suitability in wind energy systems.

“…Consequently, generator frequency can be controlled by variation in load or adding variable dummy load [11], [13]. Similarly voltage can be controlled by variation in reactive power supply either by simple switched capacitors [7], switched reactors or by using power electronics such as Static Compensators (STATCOM) [16]. However, SEIG operation is usually used only for small generators [9] and using a 220kW wind generator in SEIG mode is a challenge.…”

Islands wind-powered space heating microgrid using self-excited 220 kW induction generator," IEEE Transactions on Sustainable Energy, 2014.Abstract--Energy is fundamental to modern society. Increase in the oil price as well as environmental concerns have spurred the use of alternative renewable energy sources. In the Faroe Islands the readily available wind energy is an obvious source for space heating. Seasonal correlation exists between wind energy and required space heating and mismatches can be reduced by using simple water tanks as heat storages. A traditional Danish induction generator wind turbine has been erected on the island of Nólsoy to produce energy for space heating. The system is designed as a stand-alone Microgrid which needs its own control of frequency and voltage. A microcontroller is used to control frequency by matching load (heaters) to generated power and to produce the correct reactive power and voltage by switched capacitors. One challenge is the startup procedure at high winds speeds when nominal speed tend to be reached before voltage builds up by the self-excitation process. This paper reports the initial test and adaptation of the control system. Index Terms--Microgrid, wind energy, induction generator, self-excitation, space heating. Paul B. Thøgersen (M'92-SM'01) was born in Thy, Denmark, on June 29, 1959. He received the M.Sc.

-Self-excited induction generators (SEIG) are gaining importance as compared toconventional generators due to their capability toconvert wind energy into electrical energy for a wide range of variation in operating speed. The performance of such a generator depends upon the load, rotor speed and excitation capacitance. Therefore, depending upon the operating conditions, the output voltage and frequency of this machine goes on changing and this imposes a restriction on its usage. In order to maintain constant voltage and frequency, it need controllers, which make the circuit complicated and also increases the overall cost of power generation. This paper presents a simple controller to regulate the output voltage and frequency of SEIG for variation in its operating conditions due to any change in load, rotor speed and excitation capacitance (R, N, C) and their combination. The controller presented is simple in design, user friendly and is also less expensive, as the elements used in the controller are only resistors, inductors and capacitors. A block of SEIG for steady state operation is also modeled and presented in this paper.SEIG, Controller and other components are modeled and simulated using Matlab/Simulink.
