This paper presents an algorithm for locating and design of a capacitive compensator to improve angle stabilities of synchronous machine DGs in a micro-grid. The proposed algorithm uses the notion of trajectory sensitivities to determine the sensitivity of DGs rotor angles versus the susceptance of a compensator. Then, via the sensitivity analysis of the micro-grid subsequent to a pre-specified fault,...
Series compensation of long transmission lines is widely used in electrical power systems in order to reduce losses and increase the transmission line capacity. However, for certain values of compensation, the series connected capacitors interact with the mechanical elements of the turbine-generator group leading to sub-synchronous resonance, which could damage or destroy the generation unit. Due...
This paper presents a suitable method for time-domain identification of synchronous machine parameters from the hybrid state model recently introduced by the authors in a compact matrix form. The saturated version of this model is developed in terms of generator equivalent-circuit parameters. The load rejection test of a combined resistive/inductive load is performed for the parameter identification...
