Abstract

The invention discloses a wind power plant active power change rate control system. The system comprises a wind power plant power assembly, a control module, a grid connection point module, an activepower change rate maximum limit value calculation module, an active adjustment direction judgment module, an active power actual output value detection module, a timer module, a storage module and a rolling correction module. In the invention, periodic adjustment and real-time sudden drop detection are combined, and a problem that an active power change rate of a wind power plant is out of limit under various meteorological conditions can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of electric power system control, and in particular relates to a wind farm active power change rate control system. Background technique: [0002] In recent years, wind power has been vigorously developed as a renewable clean energy power generation. Wind power generation is random and intermittent, and the large-scale connection of wind power generation has a great impact on the safe operation of the power system, especially the short-term and large-scale fluctuations of wind power power will bring a huge impact to the power grid. "Q / GDW 1392-2015 Technical Regulations for Connecting Wind Farms to the Grid" puts forward specific requirements for the 1-minute active power change and 10-minute active power change limits of wind farms under normal operation conditions, so it is necessary to Study the control method of the active power change of the wind farm to ensure the safe and stable operation of the powe...
