The invention discloses a transient reactive power optimization method, a transient reactive power optimization device and a transient reactive power optimization system for an ashore grid-following type converter station, and belongs to the technical field of flexible direct current power transmission of offshore wind power. The ashore following grid type converter station rapidly optimizes active and reactive instruction values to enable the converter to output more active power and realize voltage support, so that overvoltage and new energy off-grid caused by surplus power of the offshore wind power flexible direct current system are relieved; and meanwhile, no hardware cost is increased, and a control program is optimized only on the basis of an existing controller of the converter station, so that more active power can be output to the outside by the shore-following grid type converter station, and the surplus power on the sea is reduced. 本发明公开了一种岸上跟网型换流站的暂态无功优化方法、装置和系统，属于海上风电的柔性直流输电技术领域，本发明通过当海上风电柔直系统中岸
