He focuses on how to decide what type of technology is best for a cement plant and whether there is a clear-cut advantage in using one type over another. He suggests a numer of variables to consider, including harmonics, efficiency, line isolation, the cost of equipment, installation cost, and the application environment. He concludes that, when considering inverter technologies, a plant manager can be confident that a low-voltage inverter with transformers and a direct-connected medium-voltage inverter are equal in technology, and suggests that the inverter that best minimizes harmonics and losses should be considered when evaluating a final selection of equipment.<<ETX>>","PeriodicalId":118848,"journal":{"name":"30th IEEE Cement Industry Technical Conference","volume":"5086 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1988-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126107517","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}

Process operators were provided with state-of-the-art color graphic CRT interfaces and full-range supervisory functions. This system, based on the INDUSTAR integrating software, has been proved to be reliable and powerful and is easily installed, configured, and later modified by local plant process engineers without special computer training. The system is also used for automatic supervisory control of the raw-mix blend and kiln operations using modeling algorithms and artificial intelligence, maintenance guides, and data collection for production cost accounting. Operation of the Bussac system and the others now installed at 16 cement and lime plants proves that INDUSTAR is fully reliable, even in this severe industrial environment, and delivers more performance than most minicomputer-based systems.<<ETX>>","PeriodicalId":118848,"journal":{"name":"30th IEEE Cement Industry Technical Conference","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1988-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126180856","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}

An alternative configuration with dual supplies and control systems is described that provides highly beneficial electromechanical system interactions. These interactions will prevent costly gear maintenance problems resulting from vibrations at the two lower-order torsional resonances. It is recommended that this arrangement be adopted as a standard on all new kiln drive installations.<<ETX>>","PeriodicalId":118848,"journal":{"name":"30th IEEE Cement Industry Technical Conference","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1988-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116624699","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}
