The invention discloses an equivalent parameter calculation method and system for providing inertia support for new energy. The method comprises the steps that the power fluctuation state of a power grid is detected in real time; when it is detected that the power grid power fluctuates and the power grid frequency variation caused by the power grid power fluctuates meets a preset input condition, providing step-type power through the new energy station to carry out inertia support of the power grid frequency; and after the new energy station provides step type power support, calculating equivalent parameters of inertia support of the new energy station. 本发明公开了一种用于新能源提供惯量支撑的等效参数计算方法及系统，其中方法包括：对电网功率波动状态进行实时检测；当检测到电网功率波动并且电网功率波动导致的电网频率变化量符合预设投入条件后，通过新能源场站提供阶跃式的功率进行电网频率的惯量支撑；在所述新能源场站提供阶跃式的功率支撑后，对所述新能源场站的惯量支撑的等效参数进行计算。
