dc.description.abstractThe objective of the proposed research is to develop a systematic way to (a) quickly and reliably protect transmission line from internal faults; and (b) accurately find the location of the fault. To solve above protection and fault locating problems, a new Dynamic State Estimation (DSE) based algorithm is proposed. The algorithm requires a device dynamic model, a model of measurements and a dynamic state estimation process. The overall Dynamic State Estimation based algorithm is implemented in an object-oriented way with the use of a standard syntax referred to as State Control and Parameter Algebraic Quadratic Companion Form (SCPAQCF). Specifically, for the protection application, the method finds internal faults by evaluating the consistency between the measurements and the dynamic model of the transmission line. For the fault locating application, the method estimates fault location as a parameter of the dynamic model of the transmission line. Also, a parameter identification algorithm during normal operating conditions is introduced to ensure the accuracy of the dynamic models.
