Stability control device for improving controllability of wind power field and coordination control method for EMSs of wind power field

The invention discloses a stability control device for improving controllability of a wind power field and a coordination control method for EMSs of the wind power field, and belongs to the technical field of power systems and automation thereof. On one hand, the stability control device serves as a stability control system execution station and can execute the emergency feeder line cutting action in an emergency; on the other hand, the stability control device serves as a contact junction between EMS systems of the wind power field and a wind power dispatching center, output of the wind power field is monitored in real time, operation information of the wind power field is uploaded, control plans are reasonably decomposed to the EMS systems of the wind power field, the stability control device serves as a reserve means for power regulation of the wind power field, enforcement measures are taken for the wind power field of which the power is not regulated in place, and power grid safety and wind power dispatching fairness are guaranteed. Controllability of the wind power field can be improved, on the premise that safety and stability of a power grid are guaranteed, wind and wind complementation is achieved by making full use of the spatial and temporal disparities of wind resources of the wind power field, and the wind power utilization rate is increased.
