An islanded microgrid (MG) including low-inertia converter-based distributed generations (DGs) is subjected to instability. The virtual inertia concept was proposed alleviate the stability issues by imitating synchronous generators behavior. This paper spotlights on optimization of generator (VSG) parameters and impedances (VI) in MGs using particle swarm (PSO). A small-signal model for MG deve...

The amount of waste can be overcome, some efforts are needed to reduce it. This research will focus on the numerical model a solid power plant. Researchers replace turbine with an impact which have specification certain pressure, rotates generator purpose this is get rms voltage generator, where capable supplying voltage. effort made convert energy into electrical energy. Generators main topic ...

This paper describes the application of static var compensators, (SVC) on an electrical distribution network containing two large synchronous motors, one of which is excited via a three-phase thyristor bridge rectifier. The second machine is excited via a diode bridge rectifier. Based on linear optimization control (LOC), the measurable feedback signals are applied to the control system loops o...

This article proposes a new rotor interturn short circuit (RISC) fault analysis model for the electromechanical property study in synchronous generators. The specific novelty of this lies two aspects: First, It considers that most generators exist static air-gap eccentricity (SAGE), so it analyzes RISC under normal and SAGE, making more versatile, second, takes into account not only degree, but...

Various faults in ship’s electrical power system, primarily those connected with diesel-generators, governors and automatic voltage regulators, may lead to oscillations in generator load, voltage and frequency. If those transients are large enough, a partial or total blackout may occur. In order to prevent such events, it is very important to get an insight into dynamic behaviour of electrical ...

The Eastern Interconnected power system in North America (depicted in Fig. 1), which stretches from the Rockies to the Atlantic Ocean including the eastern provinces of Canada to the North and Florida to the South but excluding the State of Texas, is the largest “machine” engineered by humankind. Every generator or synchronous machine connected to the system operates in synchronism with every o...

Abstrac t This paper deals with an Extended Kalman Filter (EKF) based fault detection for inter-turn shortcircuit in Permanent Magnet Synchronous Generators (PMSG). A specific faulty model in d-q frame is developed to estimate the number of short-circuited turns which are used to a fault indicator setting up. Simulation results demonstrate the sensitivity and the robustness of the chosen indica...
