This work presented in this article aims at designing and analysingalternate methods for tuning of the Proportional – Integral Derivative (PID) controller plants that do not possess ultimate parameters (ultimate gain period). The motivation lies fact conventional such as Ziegler-Nichols (Z-N) approach require PID controllers. However, because there exist some which have these parameters, hence it is difficult to design controllers using approaches directly. So, a need alternative ways...

This paper presents a new algorithm, namely, three-phase-angle for accurate characterization of three-phase unbalanced voltage sags, associated with line-to-line and single-line-to-ground faults, from recorded waveforms. algorithm uses the relation between angles voltages angle characteristic voltage.

This study presents a new classification of voltage sags which is based on its types, characteristic and zero‐sequence component voltage. It extremely difficult to distinguish between the have same type, due load effects hence such significant. The proposed mathematically justified by introducing two indices, namely, phase‐to‐neutral phase‐to‐phase indices. Using theoretical relation these it has been revealed that voltages, mathematical relations. Further, reveal accuracy type detection,...
