The invention relates to the technical field of new energy access and control, and specifically provides an online calculation method and device for increasing the power of a wind farm under frequency disturbance conditions, aiming to solve the technical problem of inaccurate calculation of the increasing power of a wind farm. In the process of calculating the additional generating power of the wind farm, it is determined according to the frequency support control mode adopted when the wind turbines participate in system frequency adjustment, the support time corresponding to the frequency support control mode, and the active power of each wind turbine unit after the frequency support control mode ends. The output active power during the control period of the above-mentioned frequency support control mode, and then calculate the additional power of the wind farm; this scheme considers the active power of each wind turbine after the frequency support control mode ends, from the two perspectives of inertia response and primary frequency modulation Calculate the increaseable power of the wind farm frequency support process to reduce the calculation error of the wind farm's increaseable power.
