The redox flow battery is connected to wind park bus through a current controlled voltage source converter based on hysterisis current control. Keeping in view the non-linear and time varying nature of the hybrid wind-diesel-redox flow battery system, neuro-adaptive control is proposed for active/reactive power modulation of the redox flow battery.","PeriodicalId":262597,"journal":{"name":"2006 International Conference on Power Electronic, Drives and Energy Systems","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129056213","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The generator consists of a three-phase star connected induction machine with three capacitors and a single-phase induction motor load. The dynamic models of the SEIG and the motor load have been developed based on stationary reference frame d-q axes theory and the equations of excitation capacitors are described by three-phase abc model. Heavy transients occur during the switching of induction motor and the system becomes unstable. The use of damping resistors across series capacitors is proposed to damp out the transients for the stable operation. Using the damping resistors, the motor can be started up successfully. Simulated results have been compared with the experimental results for unsuccessful starting without damping resistances and successful starting with damping resistances to validate the developed model.","PeriodicalId":262597,"journal":{"name":"2006 International Conference on Power Electronic, Drives and Energy Systems","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124622720","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
