| Abstract: | The features and calculation method for harmonics are researched while electric vehicle(EV) charging station is switched into public power grid.On the basis of establishing simulation model for charging station harmonic calculation,by means of analyzing simulation data and harmonic feature of charging station,a simplified engineering calculation method for harmonic in charging station is proposed.In the proposed method,a linear piecewise function is adopted to approximate the equivalent nonlinear resistance of charger and is used to calculate harmonic variation characteristic and the maximum of harmonic during a charging cycle.Calculation results verify the usability of the proposed algorithm in engineering. |
