System and Method for Minimizing Inrush of Current During Start-Up of an Electrical Power System

Abstract:

A method for a method for minimizing inrush of current during start-up of an alternating current (AC) electrical power system connected to a power grid includes determining a grid voltage of the power grid. The method also includes charging an AC capacitance of a grid filter of the electrical power system from an initial capacitance value to a predetermined percentage of the grid voltage. Further, the method includes connecting the electrical power system to the power grid when the AC capacitance in the grid filter reaches the predetermined percentage of the grid voltage. Moreover, the method includes initiating start-up of the electrical power system.
