this paper presents a novel salient pole synchronous generator i.e. permanentmagnet-assisted salient-pole synchronous generator (pma-sgs). due to saturationof conventional synchronous generators (sgs), permanent-magnet-assisted salientpolesynchronous generators (pma-sgs) are presented. pma-sgs are a new type ofsalient-pole synchronous machines with extra permanent magnets (pms) betweenthe adjac...

This paper presents the stability enhancement of four parallel-operated offshore Wind Turbine Generators (WTGs) is connected to an onshore power system using a Static Synchronous Compensator (STATCOM). The operating characteristics of each of the four WTGs are simulated by wind permanent magnet synchronous generator while the onshore power system is simulated by a Synchronous Generator (SG) fed...

This paper presents the stability-improvement results of a synchronous generator (SG)-based one-machine infinite-bus (OMIB) system with a hybrid doubly-fed induction generator (DFIG)-based and permanent-magnet synchronous generator (PMSG)-based offshore wind farm (OWF) using a static synchronous compensator (STATCOM). The operating performance of the studied PMSG-based OWF is simulated by an eq...

This paper proposes a parallel-resonance bridge type fault current limiter (PRBFCL) to augment the transient stability of a hybrid power system consisting of a photovoltaic (PV) power generation source, a doubly-fed induction generator (DFIG)-based wind energy system, and a synchronous generator (SG). The PRBFCL is designed such a way that it can provide sufficient damping characteristics to th...

This paper presents the dynamic analysis of load following performances of split-shaft microturbine generator (MTG) and Diesel Generator systems considering P-I type load following and P-I type speed controllers under stand-alone mode of operation. In this paper microturbine system coupled with a synchronous generator (SG) is considered. The dynamic performances of split-shaft MTG and Diesel Ge...

This paper presents an investigation of the impact of multi-generator power islands on the performance of the most-commonly used anti-islanding protection method, Rate of Change of Frequency (ROCOF). In particular, various generating technology mixes including Photovoltaic panels (PV), Doubly Fed Induction Generators (DFIGs) and Synchronous Generators (SG) are considered. The Non-Detection Zone...

Considering the importance of perturbations during short circuit (SC) in power conversion devices, this study designed to find out the efficacy of symmetrical short circuit (SSC) of the synchronous generator (SG) and doubly fed induction generators (DFIG). Both wind power systems were separately built (Park’s model) and simulated. Simulation results showed that the DFIG is more efficient, fault...

To optimize the output power and reduce the frequency fluctuation in conventional fixed speed Induction Generator (IG) based wind farm, various controlling devices are used. But, this paper proposes that Permanent Magnet Synchronous Generator (PMSG) can work both as a power producing device and as a controlling device for IG. In this paper a more practical case has been considered where a wind ...

The brushless synchronous generator (SG) excitation system consists of a main exciter, permanent magnet (PMG) consequent rotor poles type, and an automatic voltage regulator (AVR). Both exciter machines have been properly designed analysed. performances are obtained by time stepping finite-element method (FEM) coupled with the external electrical circuit. An experimental machine is built measur...
