The invention provides a quick
frequency response control method and device for a
new energy power generation unit. The active power of the
new energy power generation unit is determined through a boxtransformer measuring and control device; the determined active power distribution value is sent to a
photovoltaic inverter or a draught fan converter through the box
transformer measuring and control device; the
photovoltaic inverter or the draught fan converter generates power according to the active power distribution value, and not only are the
workload and cost reduced, but also the
frequency response time of the
new energy power generation unit in a new energy
station is shortened; the active power of a
photovoltaic power station can be quickly controlled, the
response time is within five seconds, and a step of
direct communication between a controller and the
inverter is omitted; signals of
voltage, current, power, frequency and the like, originally collected by the box transformermeasuring and control device, of a
transformer can be utilized for direct quick
frequency response control, hardware equipment does not need to be additionally arranged, quick
communication control is ensured, and the cost can be effectively reduced.
