Sensitivity analysis of interconnected power system low frequency oscillation
The damping sensitivity analysis of interconnected power system low frequency oscillation is studied. The function of sensitivity analysis is implemented in the Small Signal Stability Analysis Package (SSAP). The paper mainly analyzes the sensitivities of oscillation modes with respect to the parameters of power system stabilizer (PSS) in the excitation systems of generators for a physical larg...
متن کاملImpedance-Based Out-of-Step Protection of Generator in the Presence of STATCOM
This paper presents a novel impedance-based approach for out-of-step (OOS) protection of a synchronous generator. The most popular and commonly used approaches for detecting OOS conditions are based on the measurement of positive sequence impedance at relay location. However, FACTS devices change the measured impedance value and thus disrupt the performance of impedance-based relay function. In...
متن کاملSynchronization of Low-Frequency Oscillation in Power Systems
This paper presents the well-documented concept of synchronization of low frequency oscillation occurring in power systems and describes the characteristics of sync occurring in basic electrical circuits. The theory of sync, observed in basic circuits, is extended to analyze the dynamic characteristics of low-frequency oscillation in power systems.
متن کاملCoordinated Control of Doubley Fed Induction Generator Virtual Inertia and Power System Oscillation Damping Using Fuzzy Logic
Doubly-fed induction generator (DFIG) based wind turbines with traditional maximum power point tracking (MPPT) control provide no inertia response under system frequency events. Recently, the DFIG wind turbines have been equipped with virtual inertia controller (VIC) for supporting power system frequency stability. However, the conventional VICs with fixed gain have negative effects on inter-ar...
متن کاملMitigation of Low Frequency Oscillation Phenomenon in Power System by Implementing Adaptive Fuzzy Logic Controlled Power System Stabilizer
The power system stabilizer is used to damp out the low frequency oscillations that improve the small signal stability of the power system. If ignored these low frequency oscillations may lead to cascaded failure of the complete power system. This paper presents the comparative study of conventional power system stabilizer (CPSS) with newly proposed Adaptive Fuzzy Logic Controlled Power System ...
