| description | The invention discloses a subsynchronous oscillation suppression method and device for an offshore wind power direct current collection system. The method comprises the following steps: acquiring a valve side alternating current voltage value usabc and a valve side alternating current value isabc; inputting the valve side AC voltage value usabc and the valve side AC current value isabc into an adaptive fuzzy neural network, and outputting a virtual resistance value Rdamp; based on the virtual resistance value Rdamp, the dq-axis component isdq of the valve side current and the dq-axis component usdq of the valve side voltage, a voltage value u'sdq fed back to converter valve outer ring control is determined. According to the method, the subsynchronous oscillation suppression capacity of a direct current collection and transmission system of offshore wind power and the like is improved, and the operation stability of the whole system is improved.
