The conventional sensorless filed oriented control scheme require high performance digital processing and complicated calculation and are not suitable in applications to low cost fan motor drivers. Hence, simpler control method such as V/f drives which consist of the stabilization and the high efficiency control have been proposed. The proposed I/f control scheme combines power factor control and current loop control to achieve low distortion current as well as high efficiency motor torque control over wide speed control range. Compared with the V/f control scheme, the I/f control scheme can achieve high quality current waveform under larger motor parameters uncertainty. An optimal power factor angle as a function of speed is constructed based on the fan motor torque-speed characteristics as well as the motor parameters. A power factor angle detector and regulator is used to achieve optimal torque generation. Simulations and experimental results have been obtained to show the effectiveness of the proposed scheme.","PeriodicalId":236136,"journal":{"name":"Proceedings of The 7th International Power Electronics and Motion Control Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128272711","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 method of design and specific parameters of the PI compensation network were provided and the open-loop transfer function of the system was deduced. The incremental PI control algorithm was adopted and the digital control was realised by TMS320F2812 DSP system programming.

The RTGC system requires the power from diesel-engine generator because it moves around the yard. Significant fuel savings by reducing the engine speed can be achieved, because all of operation modes except hoist-up is required lower power than rated value of engine. When low speed operation output voltage of generator is decrease until acceptable range of motor driver inverters and auxiliary load supplier. According to power demand engine speed is varying from 20 to 60Hz, and voltage is varying between 210Vac and 480Vac. When idle mode or low power operation dc/dc converter operates by constant output voltage control and inverters dc site voltage is compensated by it. This paper proposed 3-phase interleaved boost converter which has the same structure as the commercially available 3-phase inverter and current sharing capability. 400kW interleaved converter is designed and a performance of converter is evaluated through several experiments with a RTGC system. That system can cut down fuel consumption by 36% and 21.3% at idle and unidirectional load operation.","PeriodicalId":236136,"journal":{"name":"Proceedings of The 7th International Power Electronics and Motion Control Conference","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124108486","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}
