<span lang="EN-US">Synchronous generator conventional model accurately describes only the stator circuit. Concerning transients for rotor quantities, example voltage, current, and magneto-motor force, conceivable predetermined with acceptable accuracy if calculations are created on equivalent properly consideration of field damper together circuits. Unfortunately, it was recognized that s...

Renewable energy sources (RESs) are generally connected to the grid through power electronic interfaces, which generate electrical instantaneously with little inertia. With increasing penetration of RESs, will gradually develop into a low inertia and underdamped system, results in serious frequency stabilization problems. The virtual synchronous generator (VSG) is an emerging technology that mi...

This paper analyses the performance of local passive islanding detection methods for synchronous distributed generators, under different grid and load scenarios. These methods monitor electrical parameters at the interconnection point of a distributed generator and detect island situation whenever these parameters change correspondingly. Lately, islanding detection research has been focused on ...

Several recent cryptographic constructions – including a public key encryption scheme, a fully homomorphic encryption scheme, and a candidate multilinear map construction – rely on the hardness of the short generator principal ideal problem (SG-PIP): given a Z-basis of some principal (fractional) ideal in an algebraic number field that is guaranteed to have an exceptionally short generator with...

Abstract—This paper investigates the thermal issue of permanent magnet synchronous generator which is frequently used in direct drive gearless small-scale wind turbine applications. Permanent Magnet Synchronous Generator (PMSG) is designed with 2.5 kW continuous and 6 kW peak power. Then considering generator geometry, mechanical design of wind turbine is performed. Thermal analysis and optimiz...

Tendencies in development of wind power industry including direct-drive small-scale wind power plants and generators have been analyzed. Synchronous generators with permanent magnet excitation for direct-drive wind power turbines are described. Primary magnetic field distribution and effect of armature reaction have been studied for design of a low-speed multipole permanent-magnet synchronous g...

An analysis of a synchronous generator in a bond graph approach is proposed. This bond graph allows to determine the simplified models of the system by using singular perturbations. Firstly, the nonlinear bond graph of the generator is linearized. Then, the slow and fast state equations by applying singular perturbations are obtained. Also, a bond graph to get the quasi-steady state of the slow...

This paper presents an efficient hybrid neurofuzzy control scheme for synchronous generator. The scheme proves to be beneficial as the control scheme targets for the better control of Synchronous generator when used along with other sub systems. The system is stabilize after t=0.13. The control parameter the performances indices of IAE are 4.755 for fuzzy and 7.242 for hybrid neuro fuzzy and fo...

The very nonlinear nature of the generator and system behaviour following a severe disturbance precludes the use of classical linear control technique. In this paper, a new approach of nonlinear control is proposed for transient and steady state stability analysis of a synchronous generator. The control law of the generator excitation is derived from the basis of Lyapunov stability criterion. T...

This paper presents a new method for implementing Artificial Neural Network (ANN) observers in estimating and identifying synchronous generator dynamic parameters based on one statistic feature extraction from the operating data using obtained measurements from time zone information. Required data for training the neural network observers are obtained through off-line simulations of a synchrono...
