An ever present issue when interfacing these sources is that of harmonic distortion reduction at the inter-tie point. One very interesting approach to reduce harmonic distortion is to synchronize power transistor operation for inverters operating in parallel. In this paper, a rarely employed technique for harmonic reduction using synchronized phase shifted parallel PWM inverters with current-sharing reactors is presented and analyzed. Using the technique presented inverter output distortion can be reduced significantly, for example total harmonic reduction can be reduced typically in half using just two synchronized phase-shifted parallel inverters (our simulation and experimental studies indicate that even smaller distortion reduction factors can be achieved). We present analyses for two and three phase-shifted inverters operated in parallel employing current sharing reactors. Our analyses consider the impact of a wide range of phase-shift delays on net output total harmonic distortion, with the phase-shift delay from zero to one entire cycle of the fundamental component. Some results are expected, such as a dramatic increase in distortion when the fundamental components between multiple inverters tend to cancel out, on the other hand it is interesting to observe a leveling-off, and gradual, smooth increase in the distortion reduction factor over a significant portion of the phase-shift delay variable.","PeriodicalId":196861,"journal":{"name":"2007 IEEE Canada Electrical Power Conference","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116062167","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}

For connecting a small synchronous generator to the utility grid, DG interconnection guidelines require the use of a transfer-trip scheme when the minimum load of a connecting feeder is less than twice the rated capacity of the total DG units. Some standards (e.g. IEEE Std. 1547) suggest a more aggressive generation to load ratio of one-third. Implementation of a fast communication based transfer-trip scheme with a detection time of less than a second is very expensive and not economically feasible for small DG projects. The fast islanding detection is mainly required to comply with the feeder protection coordination, especially the first reclosing time of the feeder automatic reclosure (in this case 1.5 seconds). This paper presents the computer modelling, simulation, and field verification of a proposed passive, local anti-islanding protection scheme based on directional reactive power measurement. The protection scheme was tested on a farm-based biogas DG to demonstrate compliance with the utility requirements. The detailed simulation studies and field tests consistently yielded detection times of less than 0.25 seconds. Based on these results the solution and the DG interconnection were approved by the utility. The proposed protection scheme can effectively be utilized for anti-islanding protection of synchronous generator based DG units on feeders with inductive load.","PeriodicalId":196861,"journal":{"name":"2007 IEEE Canada Electrical Power Conference","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127817100","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}
