Abstract
The invention discloses an online monitoring method of a reactive power control capability of a wind power plant. The method comprises the following steps: firstly, constructing a wind power plant reactive power control capability aggregation evaluation model in combination with wind power plant operation state information measured by a field measurement mutual inductor; then selecting a relatively small reference point to update a threshold parameter based on previous application experience to construct a wind power plant reactive power control capability online monitoring model; on the basisof the above model, according to related operation data accumulated step by step, fitting a quantitative relation of evaluation errors and evaluation time consumption in a daily operation scene of the wind power plant with respect to threshold parameters through a data driving method; and finally, constructing a reference point updating threshold parameter optimization model and solving to obtainan optimal value for evaluating a dynamic updating threshold of a reference point so as to realize an optimal operation effect of the wind power plant reactive power control capability online monitoring model.
