DC microgrids are gaining popularity over ac microgrids, because of high efficiency and reliability with low installation cost. To achieve equal load sharing (in per unit) among sources, droop based controllers are used. However, equal sharing of load is achieved in ideal system. This paper investigates the deviation in load currents from their ideal values. Steady state mathematical model of the...
A new generalized model for stability analysis based on a small signal modeling is proposed, for matrix converter fed induction motor drive system. This approach considers the analysis when the drive system operates at unity as well as non-unity input power factor at the source side. With the help of this model, different factors which affect the matrix converter stability are analyzed including stator...
The steady state analysis of self excited induction generator (SEIG) is vital for proper implementation of induction machine operation as a generator in a stand alone mode through appropriate modeling. This paper presents a user friendly software based solution for complete evaluation of steady-state behavior of SEIG under different operating conditions. The mathematical modeling of the machine is...
Through a small current grounding system of single-phase grounding to steady state and transient analysis and the existing line selection methods are analyzed and compared, their advantages and shortcomings can be gotten. The line of the selection method in the future was pointed out. The wavelet analysis was introduced to selection methods of faults and the fault lines can be selected in the wavelet...
