The mission statement for these Hull, Mechanical, Electrical & Damage Control (HME&DC) systems may be summarized as: Provide continuous mobility, power, and thermal management for shipboard combat systems despite major disruptions involving cascading failures. This challenge problem is prototypical of analogous complex, interdependent systems including the national power grid, military and civilian infrastructure, and transport systems. These nonlinear, distributed, heterogeneous, variable structure systems contain dynamically interdependent subsystems. Mission/life critical system integrity and fault tolerance requirements demand dependable continuity of service. Innovative, dependable, and affordable control system architectures, strategies, algorithms, methods and tools are sought.

This sort of scenario will often be accompanied by a consideration for a drive retrofit project. This paper presents a tutorial style review of DC and vector control AC drive systems.

A unified power flow controller (UPFC) with its capability to regulate significant amounts of real and reactive power flow simultaneously and independently can, at its full capacity, exert effects on the system that are strong enough to be counted as transient events. In the worst scenario, improper operations of UPFC might jeopardize the system stability. In this paper, a mathematical representation is developed for a simple power system with UPFC installed. Insight into the mechanism of UPFC is obtained. Stability criteria are studied for three different UPFC control strategies: fixed parameters control (FPC), in phase voltage control (IPVC) and quadrature voltage control (QVC). It is found out that FPC always has the smallest stability margin, while QVC has the biggest stability margin at stressed conditions, and IPVC has a slightly better result at medium real power output level. Therefore, under stressed conditions, QVC should be employed whenever possible.","PeriodicalId":117177,"journal":{"name":"IEEE Power Engineering Society Summer Meeting,","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124690591","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}

PLC (power line communications, sometimes called PLT, standing for telecommunications) uses unshielded, 230 V/50 Hz low voltage distribution cables inside and outside of buildings (mostly buried) as transmission medium for Mbits/s data rates. This requires mains injected radio frequency levels (mW, 1-30 MHz) that are EMC critical. Aside from the international standards making process, there are new German regulations in place (RegTP, NB 30-07/01) presently controlling radiated emissions below 30 MHz, in the short wave user spectrum. This includes sensitive monitoring/communication services in both military and government. The latest developments with pro and cons are analyzed, simulations discussed and compared to first, EMC critical measurement results from available real wide-spread PLC systems.","PeriodicalId":117177,"journal":{"name":"IEEE Power Engineering Society Summer Meeting,","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125029890","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}

HVDC links can be in fact effectively used for damping electromechanical oscillations, stabilizing power swings, reducing the life-fatigue effects of sub-synchronous resonance (SSR), etc. The development of voltage source converter (VSC) technology (used for instance in HVDC Light interconnections) can improve also the network voltage compensation and the transmission grid load-ability, reducing the risks of voltage instability and collapse. The paper mainly focuses on the power modulation strategies designed for two Italian HVDC links, the Sardinia-Corsica-Italy link (SACOI), with more than ten years of commercial operation after refurbishment by ENEL and EDF, and the Italy-Greece link (GRITA), more recently put in service by ENEL and PPC. These mono-polar links with sea return (rated voltage 300 kV and 400 kV respectively, rated current 1500 A and 1250 A respectively, rated power 300 MW and 500 MW respectively) are based on conventional grid commuted double thyristor bridges. The permanent or transient critical conditions of network islanding are faced by high speed and low droop frequency regulators, characterized by flexible and effective control operations.","PeriodicalId":117177,"journal":{"name":"IEEE Power Engineering Society Summer Meeting,","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129873337","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}

ATC is a transmission owner within the Midwest Independent System Operator (MISO). ATC's two major objectives are to ensure reliable operation of its transmission system and to provide an adequate infrastructure to meet the needs of all customers. ATC began operations, and its new approach to transmission planning, on January 1, 2001. The fundamental underpinnings of ATC's approach to transmission planning are customer need and public input. ATC intends to propose transmission options to resolve customer needs as expressed through load growth forecasts, new load interconnection requests, long term transmission service requests, generation interconnection requests, need for improved operational reliability, need for resolution of local and regional congestion, need for replacement of old facilities, need for increased operational efficiency, and so on. To facilitate acceptance and implementation of any proposed plans, ATC believes the public, including all stakeholders, must be invited to participate in an open, iterative, and interactive public planning process.","PeriodicalId":117177,"journal":{"name":"IEEE Power Engineering Society Summer Meeting,","volume":"148 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2002-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132773276","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}
