Dynamic behavior of doubly fed induction generator during network voltage dips

Posted on January 29, 2016 by Matlab-Projects |

The doubly fed induction generator (DFIG) is one of the mostly used options in variable-speed wind power generation. The present paper deals with the transient behavior of the DFIG during…

The electric drive with indirect frequency converter and asynchronous motors with improved immunity against the supply voltage dips

Posted on January 29, 2016 by Matlab-Projects |

This paper solves problematic of immunity against the voltage dips, of the power supply of the electric drive with induction motor supplied from the indirect frequency converter. There are demonstrated the…

Combined modeling of supply interruptions and voltage dips in a smart grid scenario

Posted on January 29, 2016 by Matlab-Projects |

Modeling of supply interruptions and voltage dips caused by component failures and scheme reconfigurations in an electrical distribution scheme is considered in a Smart Grid scenario. Explicit reference is made to a…

DFIG-based wind energy conversion systems under unbalanced voltage dips

Posted on January 29, 2016 by Matlab-Projects |

With the uptake of wind power increasing steadily on a global level, the grid compatibility of wind energy conversion systems (WECS) must be improved to ensure that electrical networks with…

AC-machine with frequency converter with immunity to voltage dips

Posted on January 29, 2016 by Matlab-Projects |

This paper solves problematic of supply voltage dips and their influence to modern electric drive (i.e. induction machine supplied from indirect frequency converter). The paper presents the control algorithms for basic variant…

Overvoltages due to Synchronous Tripping of Plug-in Electric-Vehicle Chargers Following Voltage Dips

Posted on January 29, 2016 by Matlab-Projects |

Plug-in electric vehicle (PEV) charging equipment incorporates protection that ensures that grid disturbances do not damage the charger or vehicle. When the grid voltage sags below 80% of nominal, undervoltage…

Comparison of control strategies for grid-connected photovoltaic systems during unbalanced voltage dips

Posted on January 29, 2016 by Matlab-Projects |

Unbalanced voltage dips are common disturbances in power systems. Therefore, grid-connected photovoltaic systems need to be able to work during these disturbances. Conventional control strategies do not consider the negative sequence current…

Improvement of the availabiliy of the DFIG wind turbines during voltage DIP with crowbar circuit

Posted on January 29, 2016 by Matlab-Projects |

The purpose of this paper is to solve the problem of disconnection of the wind turbines from the grid in order to increase the annual benefits from the wind farm.…

On flatness-based control for series-connected VSC for voltage dip mitigation

Posted on January 29, 2016 by Matlab-Projects |

The grid connected series converter is a custom power device that is mainly used for mitigation of voltage sags. In this paper a novel direct flatness-based control (FBC) in cascade…

On the role of photo-chemisty vis-a-vis-electrodynamics in controlling sunrise undulation of the F region peak altitude at the dip-equator

Posted on January 29, 2016 by Matlab-Projects |

This paper shows that, contrary to previous explanations, the apparent undulating motion of the equatorial F region peak at sunrise is produced mainly by photochemistry rather than dynamics. Our study…
