  "textContent": "A wind farm, and a method for controlling high voltage ride through, a system, a MMC and a machine-side converter therefor are provided. The method for controlling high voltage ride through control method for the wind farm includes: determining an amplitude of a voltage of a power grid; determining that a high voltage ride through event is occurred under a condition that the amplitude of the voltage of the power grid exceeds a first threshold; acquiring a fundamental frequency modulation wave of the MMC; superimposing a triple harmonic on the fundamental frequency modulation wave to obtain a superimposed modulation wave; and controlling the MMC to operate basing on the superimposed modulation wave.",
