It is necessary to equip the system to control active power continuously and rapidly. In recent years, a variable speed flywheel generator (VSFG) has been used to compensate the flicker caused by arc furnaces. In this paper, the authors propose to use the VSFG to stabilizing a power system and show that a parallel-type VSFG stabilizes system power swings and series-type VSFGs generate reactance voltages to compensate for the line inductance of power systems. Experiments using a motor-generator set simulator with a wound-type induction motor with a flywheel are carried out to demonstrate the stabilizing and controlling abilities of such a scheme.","PeriodicalId":262154,"journal":{"name":"Proceedings of Power Conversion Conference - PCC '97","volume":"145 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123270811","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 control is based on direct field orientation with a rotor flux simulator, and motor parameters in the simulator are estimated by a robust identifier with no sensitivity to the stator resistance. Owing to model mismatch in the controller caused by the equivalent core loss resistance, however, both the field orientation and the parameter identification cannot be carried out perfectly, which results in degradation of torque control performance. In order to improve accuracy of the output torque, the proposed system employs a modified machine model taking the core loss into consideration. Consequently, it has been verified through computer simulations that the technique achieves high precision in torque control within a few percent errors.","PeriodicalId":262154,"journal":{"name":"Proceedings of Power Conversion Conference - PCC '97","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121585848","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}

This paper presents a novel method of controlling the neutral point voltage by adjusting the dead-time that is required to prevent a DC-link short circuit. To analyze the dynamic effects of dead-time, a state-space averaged model for an NPC power converter is derived. This control method is applicable to single-phase NPC power converters, independent of the polarity of power flow, and free from the undesired variation of switching frequency of PWM. Experimental results have revealed satisfactory control performance.","PeriodicalId":262154,"journal":{"name":"Proceedings of Power Conversion Conference - PCC '97","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122613267","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 proposed method keeps the control characteristics of SVC constant even if the reactance of the power source side fluctuates, while the control response of the conventional method is easily affected by fluctuations in the power source side reactance. We applied the model reference adaptive control (MRAC) method in the proposed method. However, we did not take load fluctuations into consideration in the previous paper. Load fluctuations during control operation cause an undesirable fluctuation in the adaptive parameter, and may disturb the power system or make SVC control unstable. In this paper, we describe a new control method that we have developed to maintain the stability of SVC, even if load fluctuations occur.","PeriodicalId":262154,"journal":{"name":"Proceedings of Power Conversion Conference - PCC '97","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1997-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128870755","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}
