Abstract--Reliability coherency for the transmission path withparallel lines is studied. The state probabilities of differentavailable capacities are found considering unavailability of theelectrical equipments and relay protections. 3 coherency indicesar...[继续阅读]

    Abstract--The impacts of current reverse caused by the faultsof line with series compensation (LSC) on the widely-used currentdifferential protections are analyzed. The theoretical analysis andsimulative results show that,the zero-sequence differentialpro...[继续阅读]

    Abstract--Real Time Digital Simulator (RTDS) is widely usedfor power system simulation and secondary system test. Thedevelopment of RTDS-GTNET card has made it possible to test theintelligent electronic devices based on IEC 61850 dynamically in realtime. ...[继续阅读]

    Abstract--Distribution automation system which plays animportant role in power supply observes and controls FRTUs(Feeder Remote Terminal Unit). In the field of DAS (DistributionAutomation System),many algorithm studies based on voltage,current,power facto...[继续阅读]

    Abstract--This paper investigates an offshore wind farm(OWF) integrated modular multilevel converter (MMC) -basedHVDC system under an AC fault condition. This fault occurs atthe AC-side of an MMC which performs as the master converterto maintain the DC vo...[继续阅读]

    Abstract--A stepwise inertial control (SIC) scheme of a windturbine generator (WTG) instantly increases the power output toarrest the frequency drop when a disturbance occurs; however,the output should be reduced after a preset period to preventover-decel...[继续阅读]

    Abstract--The battery is the core component of DC system insubstation or power plant,which guarantees the normal operationof the second power systems. However,because of using status,maintenance management,production design and other reasons,the premature...[继续阅读]

    Abstract--The big difference between offline /online analysison The deviation of phase angle measurement in the power grid islikely to occur,as well as the presence of the unbalance of loadflow calculation in the substation domain and the large deviationo...[继续阅读]

    Abstract--This document describes the relevant aspects of thedesign of a Systemic Protection System-SPS (Remedial ActionScheme-RAS) in the Ecuadorian Power System.Criteria and methodology are presented to evaluate the singleand double contingencies in the...[继续阅读]

    Abstract--The paper investigates existing fault locationmethods especially in existing products and compares theirperformance. Based on this,key implementation technologies arepresented. Two proposals based on one-end data and two-end datameasurement is d...[继续阅读]
