This work investigates the practical application of support vector machine (SVM) to power transformer condition assessment. Partiuclarly, this paper proposes to integrate the SVM algorithm with two heuristic optimization algorithms which are particle swarm optimization algorithm (PSO) and genetic algorithm optimization (GA). These two optimization algorithms are used for efficiently and effectively...
Power system low frequency oscillations influence dynamic behaviour of a complex power system and threaten its security. The dynamic performance of power system can be improved by damping low frequency oscillation with the help of supplementary controllers. This paper presents the design of supplementary controller for Static Var Compensator (SVC) to damp low frequency, in particular inter-area oscillations...
In this paper a method for optimal placement of Static Var Compensator (SVC) to maximize power system loadability is presented. The method is based on mixed integer linear programming (MILP) and line flow based equations are used in the formulation. This proposed method has the ability to not only determine the location and settings of SVCs, but to minimize the required compensation as well. The method...
This paper discusses a hybrid control for the Static Var Compensator (SVC) to damp power fluctuations. In the proposed control, instantaneous power is calculated from the local measurement of three phase voltages and currents. A three phase voltage vector phase lock loop is used to get the phase angle information of the terminal voltages. The SVC reactive power injection is controlled in such a way...
Low frequency oscillations with growing amplitude can be a threat to secure operation of power system. Such oscillatory behaviour can be dealt with proper design of supplementary controller with the best input signal. This paper presents a design of supplementary controller for static Var compensator (SVC) using H∞ loop-shaping technique to damp low frequency, in particular inter-area oscillations...
