Research on Optimal Scheme for Dispatching Application Oriented Fault Localization of Power Transmission Line

In combination with current status of fault information collection device for power grid , this paper presents a novel phasor matching based fault localization algorithm which matches power grid measurement value with simulation waveform to determine the fault location. Furthermore, an optimal scheme for dispatch-ing application oriented fault localization of power transmission lines is proposed , which is suitable for power networks in any structure types and enables dispatchers to judge fault location more intuitively and globally through combining grid geographic information system and visualization application. The effectiveness and ac-curacy of the scheme＇s core algorithm are demonstrated by PSCAD simulation results.
