This paper presents a new coordinated control scheme based on wide-area signals to coordinate local controllers The coordinated controller transmits the supplementary signals to the local controllers. The proposed scheme uses the energy function based on Lyapunov's stability theory for modeling a coordinated controller. In this study, the coordinated controller which is installed at system control...
Fault data synchronization for improving Two-terminal fault location algorithm is proposed. Conceptually, employing Wavelet technique, the instantaneous currents of both ends, sampled by Digital Fault Recorders (DFR), will be used to determine a transient reference point for synchronizing the DFR data before applying the Two-terminal algorithm. In the study, both symmetrical and unsymmetrical faults...
This paper examines performance of an iterative two-end fault location algorithm which is proposed by Jan Izykowski et. al. The algorithm has been tested using field measurements from digital fault recorders installed at various stations within Thailand transmission network. The computed fault locations when compared to the actual findings from the respective site reports, are satisfactorily accurate...
In this paper, design of a controller for wind power generation has been conducted. The wind power station is assumed to be a type of doubly-fed induction generator (DFIG). Model predictive control (MPC) has been employed to maximize energy output and to limit the system frequency negative impact. Under fluctuation of wind speed, test results show that power output produced from wind station using...
