  abstract: The function of protective relaying is to promptly remove
  abstract: from service any element of the power system that starts to
  abstract: operate in an abnormal manner due to a fault. Therefore,
  abstract: protection systems are critical power system components. The
  abstract: comprehensive testing of a protection system is needed before
  abstract: the relay is put into service. Combined computer simulation
  abstract: of power systems and protective relays can be used as a
  abstract: valuable preliminary step for relay performance testing. In
  abstract: this dissertation a novel relay simulation scheme, an
  abstract: automatic pseudo closed loop simulation method, is proposed
  abstract: to allow for closed loop simulation of the interaction
  abstract: between power systems and protective relays. The protection
  abstract: algorithm plays a very important role in a protection scheme.
  abstract: Computer simulation can provide a tool to evaluate different
  abstract: algorithms for a specified application. A new algorithm to
  abstract: eliminate the exponentially decaying component from the
  abstract: Fourier algorithm is proposed and evaluated using the new
  abstract: simulation approach. Three simplified methods are proposed
  abstract: to alleviate the computation burden. The performance of
  abstract: these algorithms is evaluated both in the ideal and real
  abstract: power system conditions. A commercial digital power
  abstract: transformer relay(WBX-500) is selected as the object of this
  abstract: study. This relay is described by Matlab, a high level
  abstract: language. The power system in the Electrical Power Dynamic
  abstract: Laboratory(EPDL), Huazhong University of Science and
  abstract: Technology, China, is modeled by the Electromagnetic
  abstract: Transients Program(EMTP). A new method to estimate the RL
  abstract: parameters which can be used to describe the transient
  abstract: behavior of the transformer internal winding fault is
  abstract: proposed in this dissertation. The interaction between the
  abstract: EMTP and relay modeling program illustrates that this novel
  abstract: simulation method allows for implementation of the closed
  abstract: loop simulation, and there is no need to modify the transient
  abstract: signal generation program itself. The test result in EPDL is
  abstract: used as the reference to verify if the computer simulation
  abstract: result presented in this dissertation is consistent with the
  abstract: laboratory test result. The comparison result is
  abstract: encouraging. It demonstrates that the computer simulation is
  abstract: a very good tool for protection system evaluation.
