For studying the impact of shunt compensation on the stability of large system, transient stability modelling can be used.

The variable frequency transformer (VFT) is a controllable, bi-directional transmission device that can transfer power between asynchronous networks. Functionally, the VFT is similar to a back-to-back HVDC converter. The core technology of the VFT is a rotary transformer with three-phase windings on both rotor and stator. A motor and drive system are used to adjust the rotational position of the rotor relative to the stator, thereby controlling the magnitude and direction of the power flowing through the VFT. The worlds first VFT was recently installed in Hydro-Quebec's Langlois substation, where it will be used to exchange up to 100 MW of power between the asynchronous power grids of Quebec (Canada) and New York (USA). This paper describes the VFT technology and provides an overview of the VFT equipment installed at Langlois substation.

One of the most serious problems under snow and ice accumulation is insulator flashover, which has been studied to some extent by researchers in several cold climate countries. In this paper, the AC flashover process and electrical behavior of snow deposited on a polymer insulator is the subject of study. Moreover, a mathematical model for simulating the behavior of snow under alternating voltage is presented. For this, two experimental setups were developed and from the voltage-current characteristics of snow, which were measured from several different tests, it was found that the voltage across snow and the leakage current flowing through the snow-covered insulator are almost in the same phase, which it means that a snow-covered insulator behaves as a pure resistance. The resistance of snow is not linear, as it decreases as voltage increases. An increase in length of the snow cover results in an increasing in flashover voltage, but increasing the density and conductivity of water melted from snow yields the inverse effect and causes a sharp decrease in flashover voltage","PeriodicalId":123024,"journal":{"name":"2005/2006 IEEE/PES Transmission and Distribution Conference and Exhibition","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126928567","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}

They typically occur when overhead conductors break and fall, but fail to achieve a sufficiently low-impedance path to draw significant fault current. As a result, conventional protection cannot clear them, resulting in situations that are hazardous both to personnel and to property. Texas A&M researchers spent two decades characterizing HiZ faults and developing and testing algorithms for detecting them. In the mid 1990's, General Electric commercialized the algorithms in a relay for detecting a large percentage of these faults, while maintaining security against false operations. In an effort to mitigate problems associated with these faults, Potomac Electric Power Company (Pepco) installed the HiZ relays. They evaluated the performance of these relays on 280 feeders over a period of two years and gained significant operational experience with them. Being the first utility to apply high-impedance fault detection technology on such a widespread basis makes Pepco's experience valuable to other utilities that are struggling with decisions regarding their own response to the problem of high-impedance faults","PeriodicalId":123024,"journal":{"name":"2005/2006 IEEE/PES Transmission and Distribution Conference and Exhibition","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123033306","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}
