Abstract

This work presents a novel methodology for variable speed high power Transfer Capability of a self-excited induction generator (SEIG). The proposed methodology is based on the selection of a suitable firing angle of Fixed Capacitor-Thyristor Controlled Reactor (FC-TCR) for achieving constant rated stator current. WDSEIG would produce a variable speed high power without overheating under variable wind speed and connected load. The analytical approach for the proposed methodology has been implemented to predict the optimal operating firing angle of FC-TCR for full load stator current achievement within the allowed operating range of load and prime mover speed. Also, Soft Computing (SC) techniques have been implemented based on Harmony Search Algorithm (HSA), Flower Pollination Algorithm (FPA), and Moth-Flame Optimization (MFO) algorithm to achieve the proposed methodology. A comparison between different SC techniques, analytical approach and experimental work are given and evaluated to verify SC techniques accuracy. This evaluation study can be useful in specifying the appropriateness of the SC techniques for High Power Transfer Capability for a SEIG.

Summary

INTRODUCTION

For the last twenty years, the Greenhouse is one of the crucial global challenges. So renewable energies especially wind energy have an attention increase [1]. The researchers present a new approach for the SEIG full load stator current operation, using three different SC optimizers to find the optimum FC-TCR firing angle. The model validity is investigated by done simulation analyses at different loading conditions and comparing these simulation results with experimental work as shown in figures (8), (9) and (10) These results illustrate the relation of the firing angle values with SEIG performance which will be used in proposed techniques later. (8), (9) and (10) clearly show the great acceptance of the proposed drive model results with the experimental results These figures illustrate a significant increasing in speed range around the synchronous speed at which generation system is capable to operate with increasing the firing angle values. 6- [Loop] If the iterations number < than the maximum go to step (2) with the best harmony stored in HM obtained in step (5), else stop
