The objective function is summation of electrical energy generated by DGs and substation buses (main bus). A particle swarm optimization (PSO) is used to solve the optimal operation problem.

City engineers modified their existing substation drawings to remove the existing relays and add the Siemens 7SJ63 relays with dual-fiber IEC 61850 interfaces. The dual-fiber design allows for shorter fiber runs and provides an extremely reliable redundant loop. The Chicago 50 substation controls were modified to match their existing substation designs, which also used the 7SJ63 relays. Since standards were maintained, the relay files from the existing substations could be reused and modified with the required IEC settings and feeder specific protection settings. Siemens assisted with modifications since it was the first implementation of this type in the United States. Naperville hired a contractor and made the mechanical and electrical modifications. While Naperville was working to get the relays installed, Siemens was busy building an automation cabinet and designing the substation HMI based on the Chicago 50 substation single line.","PeriodicalId":114949,"journal":{"name":"2007 Power Systems Conference: Advanced Metering, Protection, Control, Communication, and Distributed Resources","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132657148","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}

These faults are a great public safety concern because the fault currents are generally too small for detection by conventional overcurrent relays. This concern has generated great interest in the detection of downed conductor-related HIFs at the substation level. In this paper, we present an HIF detection algorithm that uses traditional relay logic. The algorithm is easier to understand and simpler to implement than many black-box detection methods such as neural networks. We discuss such key aspects of algorithm design as input quantity selection, generation of a reliable reference, adaptation to feeder ambient load noises, and decision logic based on trending and memories. We use real-world data collected from staged HIF tests and noisy substation loads to validate detection results.","PeriodicalId":114949,"journal":{"name":"2007 Power Systems Conference: Advanced Metering, Protection, Control, Communication, and Distributed Resources","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131667763","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}

Stevens","doi":"10.1109/PSAMP.2007.4740912","DOIUrl":"https://doi.org/10.1109/PSAMP.2007.4740912","url":null,"abstract":"Ageing coupling capacitor voltage transformers (CCVTs) can pose safety problems and possibly restrain system operations. Catastrophic failure of a CCVT could start a widespread fault in the substation and/or endanger personnel working in a close proximity. The latter becomes a real danger when inspecting a suspicious CCVT or when live line work is being performed. CCVT monitoring becomes more and more important as the installed population of CCVTs ages with sporadic incidents of catastrophic failures alerting both field personnel and dispatching managers regarding safety and liability. Microprocessor-based protection relays facilitate cost-efficient and broad deployment of CCVT monitoring functions across the organization. First, modern relays allow programming a number of indicators that alone, or in combination, are reliable enough to raise alarms and initiate an in-depth engineering analysis. Second, these relays can provide data recording and remote access. This data includes high-resolution data such as oscillography, and long-term trending such as the magnitude profiling. Third, relay-based CCVT monitoring schemes can be retrofitted in the existing installations. In many cases with a simple wiring and setting changes, existing relays could provide a solid CCVT health indication. The combination of reliable alarming via protective relays with remote access yields a cost- efficient, easy to implement, and safe to operate, solution. This paper presents a number of CCVT health indicators that could be programmed on modern relays via logic and simple math operands in order to monitor the CCVTs with a minimum material and labor investment.","PeriodicalId":114949,"journal":{"name":"2007 Power Systems Conference: Advanced Metering, Protection, Control, Communication, and Distributed Resources","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132438750","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}

Seeley","doi":"10.1109/PSAMP.2007.4740899","DOIUrl":"https://doi.org/10.1109/PSAMP.2007.4740899","url":null,"abstract":"Plumas-Sierra Rural Electric Cooperative (PSREC) has two interconnections with large investor-owned electric utilities. Presently, PSREC normally operates solely connected to the Pacific Gas and Electric (PG&E) system via a radially fed line. This connection to PG&E is subject to service interruption for events on the PG&E line or connecting facility. Loss of this PG&E interconnection drops the entire PSREC customer load. An alternative service interconnection is available with Sierra Pacific Power Company (SPPCo) on another part of the system. However, this alternative source does not have the capacity to carry the entire PSREC customer load. In an effort to increase the reliability of PSREC's service to its customers, future enhancements will allow the system to operate with PG&E and SPPCo in parallel, a project PSREC dubbed Marble Live. In addition, PSREC decided to implement an auto- restoration scheme based on scenarios that require PG&E to interrupt service to the PSREC system. In the case of an event on the PG&E line, PSREC will automatically island its system and execute a series of steps to reconnect to PG&E, should conditions permit, or remain disconnected from PG&E and connect to SPPCo after shedding the appropriate amount of load. This paper describes the system protection and control scheme solution that PSREC incorporated to accomplish a system restoration that satisfies the demands of both PG&E and SPPCo while increasing the reliability of service to PSREC's customers. Audio tone direct transfer trip equipment, IEC 61850 GSSE, also known as UCA GOOSE, messages among geographically diverse locations, and spread-spectrum radio among directional relays provide communication among substations, while the restoration logic resides in communications processors at each substation. The combination of protection elements and communications equipment initiates selective load shedding and restores power from the alternate power source to as many retail customers as possible.","PeriodicalId":114949,"journal":{"name":"2007 Power Systems Conference: Advanced Metering, Protection, Control, Communication, and Distributed Resources","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130549929","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}
