Nuclear Power Plant (Hungary) is developed in this paper based on first engineering principles that is able to describe the time-varying active and reactive power output of the generator. These generators are required to take part in the reactive power support of the power grid following the...

The paper deals with the modeling and the control of the hybrid excitation synchronous machine operating as a variable frequency generator that supplies an isolated load in embedded applications such as aircraft electrical power generation. The elaborated model is suitable for simulation and is...

A direct driven permanent magnet (PM) synchronous generator has been designed and constructed and results from the first experimental tests are presented. The generator has been designed using the finite element method (FEM) and dynamic simulations have been performed to study the generator. The...

In the variable speed wind turbine based on electromagnetic coupler (WT-EMC), a synchronous generator is directly coupled with grid. So like conventional power plants WT-EMC is able to support grid frequency inherently. But due to the reduced inertia of synchronous generator, its frequency...

A dynamical model that describes the interaction of the HIV virus and the immune system is presented. The effect of introducing antiretroviral therapy on the model, consisting of RTI and PI drugs is investigated, along with the result of undesired treatment interruption. Furthermore, the effect...

When a system becomes unstable or noise becomes excessive, often regulations of the form of limiters (barriers obstructing excursion into undesired areas of the phase space) are imposed. It is hoped that by the influence of this element, the system can be calmed and its behaviour can be...
