Embodiment Construction
[0023] The present invention provides a wind farm fan power distribution control device, the device includes a processor, the processor is used to execute instructions to implement a wind farm fan power distribution control method of the present invention, combined below figure 2 , 3 , for a further detailed description of the method.
[0024] First, calculate the power prediction value W of the unmeasurable power generation / power consumption equipment ncp .
[0025] Untestable power generation / consumption equipment includes two types of equipment: unmeasurable power generation fans and power station power equipment. When the wind turbine is in the power generation state but the communication link between the wind turbine and the power generation control system fails, the automatic power generation control equipment cannot obtain the direct feedback value of the power of such wind turbine. The electrical equipment of the power station includes air conditioners, induction c...

The invention relates to a wind power station fan power allocation control method and device. The method comprises the steps of: firstly, acquiring an actual power output value of each controllable fan in a wind power station in a current control period, and carrying out summation to obtain a total actual output power value of the controllable fans; acquiring a total actual output power value of the wind power station in the current control period from a grid connection point, and carrying out difference processing with the total actual output power value of the controllable fans to obtain a power predicted value of unmeasurable power generation / utilization equipment; then acquiring a scheduling instruction value of the current control period, and carrying out difference processing with the power predicted value of the unmeasurable power generation / utilization equipment to obtain a difference value; and allocating the obtained difference value to each controllable fan, obtaining a power instruction value of each controllable fan, and issuing the power instruction values to the corresponding controllable fans so as to carry out control on the controllable fans. The wind power station fan power allocation control method and device disclosed by the invention are simple and reliable in control strategy and high in enironmental adaptation, and enable power output of the wind power station to be more stable.
Description
technical field [0001] The invention belongs to the technical field of wind farm power generation, and in particular relates to a wind farm fan power distribution control method and device. Background technique [0002] Around 2000, domestic wind power stations developed rapidly, and with the rapid development of wind power, the scale of wind power expanded rapidly. In recent years, provincial electric power bureaus such as Liaoning, Gansu, Xinjiang, and Qinghai have required wind farm fan groups to participate in grid power regulation, and required each wind farm to be equipped with automatic generation control equipment (AGC), otherwise they will not be connected to the grid. However, the domestic wind power technology started relatively late, and the automatic power generation control system technology of wind farms is immature. The output power of some wind farms fluctuates too much. This disadvantage is more serious when the wind speed changes drastically. The reason i...
