The interaction between harmonic sources, other loads and the power system is investigated, using a power electronic simulator which performs an accurate time-domain analysis as described and verified in part I. An investigation is made of various load compositions involving power converter, three-phase induction motor, and constant impedance loads. The power system conditions studied include strong, weak, and parallel resonance. These results are compared with those from a simple Thevenin model of the power system to establish the limit of the model's validity. An expression showing how the harmonic current injected into the power system is affected by load comparison is derived.<<ETX>>","PeriodicalId":110710,"journal":{"name":"Conference Record of the 1992 IEEE Industry Applications Society Annual Meeting","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114113375","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 methods do not reply on assumptions pertinent to any kind of probability function. The significance of providing harmonic quantities associated with the occurrence probability is considered.

Using only two active devices with roughly one p.u. current rating, the converter can retain nearly full starting torque during motor starting with one extra capacitor and supply excellent balanced output voltage to the motor under steady-state conditions. Under positive sequence operation, the converter has no low-frequency output harmonic distortion, high total input power factor, and reasonable input current distortion. The fundamental frequency model for the system, harmonic distortion on the motor side and the input AC line side, the rating/stress for devices, reactive component selection, and the control strategies for starting and steady-state operation are detailed. Analytical, simulation, and experimental results are presented.<<ETX>>","PeriodicalId":110710,"journal":{"name":"Conference Record of the 1992 IEEE Industry Applications Society Annual Meeting","volume":"18 1-12","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114048109","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 humidity sensing dielectric used for the sensor mainly consists of a cylindrical-pore-like alpha -alumina film formed by anodic spark deposition, with a dense amorphous alumina thin barrier layer at the pore base formed by reanodization. The performance characteristics of the sensor, e.g., humidity sensitivity, humidity hysteresis, temperature dependence, response time, reproducibility, and long-term calibration stability, were studied in detail. It was found that the sensor can be used for absolute humidity detection in the range from -80 degrees C to -10 degrees C frost point as well as for relative humidity (RH) measurement from 10% to 100% RH with very stable performance.<<ETX>>","PeriodicalId":110710,"journal":{"name":"Conference Record of the 1992 IEEE Industry Applications Society Annual Meeting","volume":"51 Suppl 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127807056","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 transducer uses the synchronous machine terminal voltage and current to calculate the machine internal voltage and its frequency, which is proportional to shaft speed. Unlike the more usual shaft-mounted transducers, this transducer has no mechanical interface with the machine. Therefore the errors introduced by machine shaft vibrations, temperature changes, and other factors are virtually eliminated. The transducer was implemented using an Intel 80C196 single-chip microcontroller together with the supporting analog and digital transducers. The results of various tests of the transducer accuracy, together with the transducer main hardware and software design features, are presented and discussed.<<ETX>>","PeriodicalId":110710,"journal":{"name":"Conference Record of the 1992 IEEE Industry Applications Society Annual Meeting","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1992-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121052455","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}
