Zusammenfassung:	The invention provides a static harmonic analysis method and system for a grid connection point of a flexible direct-current power transmission system. The method comprises the following steps: acquiring background harmonic data of an alternating-current system and injection harmonic data injected into the alternating-current system by a converter station; constructing a static harmonic calculation model of a grid connection point; calculating a harmonic voltage generated by each harmonic at the grid connection point according to the background harmonic data, the injection harmonic data and the static harmonic calculation model; and calculating the single harmonic distortion rate and the total harmonic content at the grid connection point according to the harmonic voltage of each harmonic.According to the invention, by utilizing the characteristics of simple process, easy implementation and accurate modeling basis of the calculation method and knowing the harmonic content condition ofeach order of static harm
