Wind power generation control system and control method for wind farm

Abstract

The invention relates to a wind power generation control system of a wind power plant and a control method thereof. The wind power generation control system comprises a concentrated control platform and the wind power plant controlled by the concentrated control platform, wherein the wind power plant comprises a plurality of wind power generation devices which are arranged according to terrains, a plurality of wind condition measurement devices arranged in one-to-one correspondence with the wind power generation devices and wind force control devices for controlling the rotating speeds of the wind power generation devices; and the concentrated control platform comprises a control module group, a communication interface and a memory module group, and the control module group comprises a fan group module, a wind speed prediction module, an output prediction module, an output decision module and a rotating speed control module. The system and the method can accurately and stably calculate wind force, thereby better inhibiting the variation of power output by the wind power plant and keeping a constant output technology.

Description

technical field [0001] The invention belongs to the field of wind power generation control, in particular to a wind power generation control system and a control method for a wind power farm. Background technique [0002] By monitoring the meteorological data of the wind turbines at the most upwind position in the wind farm, the wind speed changes of the entire wind farm can be predicted, and the working status of each fan can be adjusted in time according to the above changes, thereby changing the power output of the entire wind farm. Therefore, how to determine which wind turbine is the most windy wind power generation device is very important. In the prior art, someone has installed a weather instrument near the wind turbines in the entire wind farm. When the wind changes, the weather instrument will transmit the change data. For the control system, the control system determines which wind turbine is the most windward device according to which wind turbine has new meteoro...

Problems solved by technology

However, in practical applications, the wind speed and wind direction are constantly changing, and the strong changes within the predetermined time will cause errors in the calculation of the predetermined period, which will have a great impact on the next prediction; that is, whether the selection of the upper wind position device is appropriate , will affect the forecast, and the wind calculation will be inaccurate within the predetermined time, especially due to the limitation of terrain and landform

When the wind direction is uncertain, the error is larger
