Development of VAR / P . F Regulator for Brushless A . C Generator for Paralleling with Grid

چکیده
The main objective is Paralleling Brushless A.C. Generator to Grid system in constant VAR or in PF mode. Presently, the trend is to feed power to Grid from different sources of potential heads. That is available in different valley regions in India for meeting the power demand. Hence, the question of feeding power to national Grid. Power generated from different mini and micro Hydel projects are fed to grid in meeting the above demand. Based on Stiff Bus concept any power feeding to Grid will not be stable. Since, the power bus from Grid is stiff in Nature. To make the Generator adoptable to parallel with Grid we need a regulator to work either in Constant VAR or Constant PF mode .So that the Generator Rotor is not over loaded under any circumstances throughout power flow pattern to Grid. To meet the above a Regulator of PF/VAR control is added to the existing AVR. So, that the excitation according to set p.f or VAR get adjustable. So, that the Generator Rotor is protected throughout. KEY WORD: AVR, Brushless A.C Generator, Grid, VAR / p.f regulator

A model-based PDPC method for control of BDFRG under unbalanced grid voltage condition using power compensation strategy
Brushless doubly fed reluctance generator (BDFRG) has been recently suggested as a wind generator. Different control methods are presented in literature for the BDFRG, but there is a gap on control under unbalanced grid voltage condition (UGVC). This paper presents a predictive direct power control (PDPC) method for the BDFRG under UGVC. The proposed PDPC method is based on power compensation s...
