It explains thermal model time constants and other technical aspects causing the biasing of the thermal model algorithm. Other topics covered in this paper show that a detailed motor data sheet's information, and coordination between the protection engineer and the motor supplier leads to proper selection of motor thermal protection parameters. This paper presents a closer look on motor stall, acceleration and running thermal limit curves, explains the concept of thermal capacity and elaborates on how thermal capacity is evaluated in motor protection devices. This paper also talks about some additional methods, such as voltage dependant and slip dependant motor overload curves, which are employed to evaluate thermal capacity in nonstandard motor applications. This paper presents the concept of matching thermal time constants for motor cyclic loads cases. Besides this, the response of a thermal model algorithm in practical applications is demonstrated. The paper also describes the real case example showing how to apply and fine tune the thermal model in high-inertia load application. In this context, the paper also explores some of the key topics that will ensure safe operation of the motor while allowing satisfactory motor design characteristics.","PeriodicalId":395312,"journal":{"name":"58th Annual Conference for Protective Relay Engineers, 2005.","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125412417","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}

Exchange of UCA Generic object oriented substation event (GOOSE) messages between relays connected to the LAN is successfully used for the breaker failure, accelerated protection of the distribution bus, transformer protection lockout feature, GOOSE testing, substation interlocking and blocking. Also, this system of exchange of the messages over LAN provides significant advantage for the future expansion of the distribution substation, as well as easy integration into automatic throw over scheme. The three relays types are used for the advanced feeder protection, transformer protection, and control of the high voltage (HV) switches. All relays have pushbuttons on the front (faceplate) for easy control and testing of substation equipment. Relay's pushbuttons, light emitting diodes (LEDs) and nonvolatile latches also reduced cost for hardware, wiring, design, testing and commissioning. This application meets Cinergy Distribution Standard in a very cost effective way, with great benefits of integration, as there is no need for additional hardware (protocol converters) or additional software. It provides an efficient way of local/remote metering, control, monitoring, recording, communication and protection functions.","PeriodicalId":395312,"journal":{"name":"58th Annual Conference for Protective Relay Engineers, 2005.","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130238434","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}
