Because of a backlog of testing, customer requirements for extended life of friction materials, and demand for larger clutches and brakes, The Clutch manufacture decided that the throughput and capacity of their existing 1500HP test stand needed to be doubled. The existing test stand utilized a 1500HP Variable frequency drive (VFD) and motor to: performance test and burnish brakes for customers, run static and dynamic load changes on clutches and brakes for research and development, and for customer specific applications. The existing VFD and motor were to remain and be re-used. A second identical VFD and motor would be added, and both would be connected to a combining gearbox. Each VFD and motor can test a single 1500HP brake, or both VFDs systems can be combined to run a single 3000HP brake. The upgrade of the test stand offers an opportunity to examine the application considerations (closed loop and torque control), installation considerations (harmonics and environmental), and operation considerations (dynamic load changes and master-follower control) of large VFD systems and clutch/brake performance.","PeriodicalId":67291,"journal":{"name":"中国石油和化工(企业版)","volume":"2 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2013-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81809327","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}

Data are transmitted at protection speeds and must be dependable for industrial power system operation and maintenance applications. The redundant electric power system Ethernet communications network is used for a supervisory control and data acquisition (SCADA) system that automates industrial electric power system operations. Within individual substations as well as between substations, communications based on IEC 61850 protocols eliminate copper control wiring, which results in reduced cost, construction time, commissioning time, and wiring errors and makes future upgrades simpler. A fast load-shedding system uses the same communications network to stabilize system frequency in response to a loss of generation by detecting the events that lead to a power deficit and automatically responding by shedding load to balance generation and load in less than 40 milliseconds. This paper focuses on integrating three major electrical control systems at a refinery onto one Ethernet network: a SCADA system for controlling and monitoring operations, a peer-to-peer high-speed communications-assisted protection scheme, and a fast load-shedding system.","PeriodicalId":67291,"journal":{"name":"中国石油和化工(企业版)","volume":"48 1","pages":"1-9"},"PeriodicalIF":0.0,"publicationDate":"2013-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80430284","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}

Periodic testing of electrical equipment leads to a safe and reliable operation. Electrical apparatus, including switchgear, motor control centers (MCC) and uninterruptible power supplies (UPS) must be de-energized periodically and taken out of service for maintenance testing, repairs or installation of additional sections to accommodate growth. The process is lengthy, with planning starting years in advance to prepare for extensive inspection and testing activities. This paper discusses the experience, findings and lessons learned at one petrochemical facility during a 70 day operational turnaround. Significant investments were made in purchasing temporary power equipment and hiring numerous electrical speciality contractors to perform maintenance testing of electrical equipment in nine substations, including 9 secondary selective automatic transfer switchgear line-ups, 67 LV MCC's and 13 UPS's. The journey covers temporary power plans, testing plans, operational issues, reporting, backfeed connections, component upgrades due to manufacturer product safety advisories, equipment repairs, inspection findings, relay firmware upgrades, training of personnel, isolation, switching, grounding plans, guarantee of isolation documentation, electrical personal protective equipment (PPE), testing equipment, and communications plans to advise of power outages.","PeriodicalId":67291,"journal":{"name":"中国石油和化工(企业版)","volume":"215 1","pages":"1-10"},"PeriodicalIF":0.0,"publicationDate":"2011-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80119423","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}
