Abstract--The traditional protection devices for the highvoltage step controlled shunt reactor (SCSR) ,detect theinter-turn short circuit fault of the control winding,through thedifferential protection which based magnetic balance and itsself-produced zer...[继续阅读]

    Abstract--With the promotion of IEC61850,substations aregetting smarter and secondary equipment are networkedobviously. This paper divides the research stage of network switchin smart substations into three stages and discusses the technicalneeds of each ...[继续阅读]

    Abstract--Disturbance on UHVDC transmission line oftenresults in the mal-operation of line protection in practice. In orderto ensure the accurate operation of line protection,A novelintegrated disturbance identification method for UHVDCtransmission line p...[继续阅读]

    Abstract--Introduce a method which accelerates EMTPsimulation by approximately equivalent reactance to distributedparameter transmission line. Give an instruction on how toapproximately equivalent transformers and reactance totransmission line using this ...[继续阅读]

    Abstract--The advanced information system of smart gridprovides a good opportunity for the development of protectionrelay. The smart substation based on IEC 61850 realizes the digitalinformation of all substation,the networking of communicationsplatform,t...[继续阅读]

    Abstract--Buchholz relay is one of the main protections fortransformer internal fault. But correct operation ratio ofBuchholz relays is much lower than transformer differentialprotection. From 2011 to 2014,more than ten 500kV transformerswere tripped by m...[继续阅读]

    Abstract--A new earth fault location method for non-effectiveearthed neutral network using transient signals measured at thebus terminal is presented. Based on the mode network of thesingle phase to ground fault,the s-domain equation of the faultyfeeder i...[继续阅读]

    Abstract--A healthy operating smart substation is based onhealthy operating process-level network. In network storm,information on network cannot be transferred normally. Devicesmay fail,which is harmful to the substation operation. In thispaper,transmiss...[继续阅读]

    Abstract--The wide area response based transient stabilityreal-time detection and emergency control technology has becomea hotspot in power system stability research field. Currentlyseveral different-principle technologies have been proposed,butthere are ...[继续阅读]

    Abstract--Minimizing the operational personnel`s injuryand the damage to the power equipment when arc flash faultsoccur in MV switchboards have always been major concernsto the utilities protection engineers. However,for variousreasons,until now almost no...[继续阅读]
