The paper presents a novel Hybrid-FACTS Based Stabilization Scheme controlled by a hierarchical two-stage fuzzy logic (HFLC)-multi loop dynamic error driven controller. The proposed scheme includes separate Fuzzy control stages for the PD and PID parts to ensure robust and effective dynamic speed control and efficient energy utilization. The PD fuzzy stage used the global error and change of error as the fuzzy input variables. The second stage is the PID-FLC regulation which utilizes the output of the PD-FLC stage and the integral of the global error as input fuzzy variables. The simulation results validate the proposed control scheme effectiveness and robustness with efficient energy utilization, improved power quality and power factor at the Common AC Bus and load bus. A Digital simulation model of the proposed system is developed in Matlab/Simulink/Simpower Software Environment using operational dynamic blocks available in Simulink library.

“…Fixed capacitors, Thyristor control reactors static VAr Compensators SVC are used worldwide for utilities purposes. The main objective of inserting such SVC systems is to regulate the node voltages at weak points of the utility grid as well as maintaining the voltage stability of industrial loads, and improving the power system dynamic performance in case of abnormal operating conditions [1][2][3][4][5][6]. The Improving such models can provide a very good response to the whole system.…”

The paper presents a new method to detect subsynchronous resonance (SSR) -shaft torsional oscillation for large induction motors and synchronous generators. This is achieved by using a novel on-line Intelligent Shaft Monitor (ISM). The ISM device utilizes stator current and frequency based transformations. The proposed detection scheme is based on the stator current-excursion patterns and relevant phase-portraits. It can also be used to damp any SSR oscillation mode using a dynamic filter and static compensator.
