Abstract

The invention discloses a sample fan method based wind power plant theoretical power computing method. The sample fan method based wind power plant theoretical power computing method comprises the following steps of performing statistical analysis on history actual measurement output data of a wind power plant sample fan and performing sample fan theoretical output analysis according to wind power output characteristics and a fan theoretical output design curve; establishing a wind power plant theoretical power computing model according to history data of a sample fan set; performing statistics on the number of actually operated fans of a wind power plant in real time according to wind power plant fan real-time information data; confirming sample fan actual operation conditions; inputting wind power actual operation data into the wind power plant theoretical power computing model; outputting wind power plant theoretical power real-time data and comparing and analyzing a wind power plant actual operation result. The sample fan method based wind power plant theoretical power computing method achieves purposes of acutely computing the electric field theoretical power and accordingly reasonably dispatching a power grid and saving energy.

Description

technical field [0001] The invention relates to the technical field of new energy sources in electric power systems, in particular to a method for calculating theoretical power of a wind farm based on a model fan method. Background technique [0002] On January 1, 2006, the official implementation of the "Renewable Energy Law" provided a new impetus and guarantee for the development of wind power. my country's wind power has entered a stage of large-scale development, "building a large base and connecting to a large power grid" It has become the main mode of wind power development. By the end of 2012, China's cumulative installed capacity was 75,324.2MW, accounting for 26.7% of the world's total, ranking first in the world. [0003] The integration of large-scale wind power has brought great pressure to the peak regulation of the power grid. Due to the constraints of peak regulation capacity and grid structure, many wind power bases have experienced large-scale wind curtailm...
