The proposed control has two instantaneous average values control loops: one for voltage and another for current. The first one controls the output voltage of the inverter while the second is designed to control the parallel operation of the inverters. The proposed parallelism control acts in the voltage before the LC filter and is based in the feedback of the L inductor current. There is no communication among inverters so that one unit is independent from the others. A prototype with 3 inverters of 5 kVA each was built to corroborate the control technique.","PeriodicalId":183864,"journal":{"name":"2009 Brazilian Power Electronics Conference","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115623121","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 initial hypothesis consider that is possible to minimize the converter's losses through the variation of motor voltage phase and through selection of an appropriate transformer. To reduce the IGBT dual module losses means to reduce the operational cost of the system. The initial investment of this configuration is very attractive for treating of a converter that works in shunt, in other words, only a part of the load power flows through the converter. Analysis in steady state has been realized, as well. Experimental results are showed to demonstrate the theoretical studied.","PeriodicalId":183864,"journal":{"name":"2009 Brazilian Power Electronics Conference","volume":"156 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116079745","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}

It follows the procedures described in the IEC standards, regarding wind turbine power quality and wind power production. The system has two basic modules. The first, called remote unit, is located on a meteorological mast and encompasses environmental signal transducers and a wireless communication system. The second, the local unit, at the turbine connection point, comprises a digital signal processor (DSP), a MCU, a memory card, as well as voltage and current transducers. Both units operate synchronously to relate the environmental signals with electrical ones. The DSP is responsible for data processing and overall system management. Data stored in the memory card can be retrieved by the end of the test campaign, resulting in power quality and performance indexes for the wind turbine under test.","PeriodicalId":183864,"journal":{"name":"2009 Brazilian Power Electronics Conference","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114690670","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}

Therefore, the key of a good design is the study of the active and reactive powers unbalance. In this paper, the unbalance of a drooping parallelism method is analyzed and practical simplifications are applied in the exact equations. These equations are then rewritten in the per unit system, making the study even more intuitive and generalizing the design. The design method is first tested with a research association of two analog based UPS inverters and then with an entire line of commercial DSP based UPS inverters.","PeriodicalId":183864,"journal":{"name":"2009 Brazilian Power Electronics Conference","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125385332","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}

Solutions based on passive filters are conventionally used to suppress the undesired high-frequency phenomena that take place in such systems, but, in turn, bring up new considerations concerning filter size, weight, cost and electrical losses. In this context, an alternative concept of a motor drive system that overcome all these problems is outlined in this paper, where the long cable is used to connect the rectifier to the inverter, thus establishing a DC power transmission link. This paper briefly discusses the benefits and important issues concerning the proposed system and presents a comprehensive analysis regarding one of its advantages, which is the copper (and cost) economy in relation to the traditional systems.","PeriodicalId":183864,"journal":{"name":"2009 Brazilian Power Electronics Conference","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123433719","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 objective of this study was to verify the operation of a line conditioner when subjected disturbances, using a digital PLL to generate the reference. The generation of the sinusoidal reference for the output voltage control loop is discussed and digital PLL (DPLL) based on the three-phase instantaneous power theory is proposed. The advantage of the use of a PLL in this work, as a reference, is due to it being immune to variations and disturbances from the mains, being sensitive to the frequency variation that enables the fundamental component of the voltage to be monitored. The conditioner control is based on the concept of multi-loop, one being to control the output voltage RMS value and other for the pre-feeding of the input voltage. Simulation and experimental results obtained with a 3 kVA conditioner are presented.","PeriodicalId":183864,"journal":{"name":"2009 Brazilian Power Electronics Conference","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122494319","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}
