Embodiment Construction

[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0021] Such as figure 1 As shown, a method for calculating the theoretical power of a wind farm based on the nose wind speed method includes the following steps:

[0022] Step 1: The input data of the nose wind speed method is the real-time data of the measured wind speed and power of the cabin anemometer, and the input data of the nose wind speed method is filtered to filter out the data representing the normal operating state of the wind turbine;

[0023] Step 2: Perform statistical analysis on the historical measured output data of a single wind turbine in the wind farm, and establish a theoretical power calculation model based on the wind power output characteristics and the...

Abstract

The invention discloses a fan head wind speed method based wind power plant theoretical power calculation method. The fan head wind speed method based wind power plant theoretical power calculation method comprises the following steps of screening input data of a fan head wind speed method and screening out data standing for a normal operation state of a fan, wherein the input data of the fan head wind speed method is real-time data of measured wind speed and power of a cabin anemometer; performing statistical analysis on history actually measured output data of every single fan in a wind power plant, fitting a power curve according to wind power output characteristics and fan theoretical output and setting up a theoretical power calculation model; performing statics on the number of actually operated fans in the wind power plant in real time according to fan real-time information data of the wind power plant; confirming the fan actual operation conditions; inputting operating fan head wind speed data into the theoretical power calculation model; outputting theoretical power real-time data of the wind power plant and comparing to analyze a wind power actual operation result. The fan head wind speed method based wind power plant theoretical power calculation method achieves purposes of reasonably adjusting the power grid, optimizing electric power transmission and avoiding energy wasting.

Description

Technical field [0001] The invention relates to the technical field of new energy sources for power systems, and in particular to a method for calculating the theoretical power of a wind farm based on the wind speed method of the nose. Background technique [0002] On January 1, 2006, the formal implementation of the "Renewable Energy Law" provided new impetus and guarantee for the development of wind power. my country's wind power has entered a large-scale development stage, "building a large base and connecting to a large power grid" Has become the main mode of wind power development. As of the end of 2012, China's cumulative installed capacity was 7,5324.2MW, accounting for 26.7% of the world's total, ranking first in the world. [0003] The connection of large-scale wind power has put a lot of pressure on the peak shaving of the power grid. Due to the constraints of the peak shaving capacity and the grid structure, many wind power bases have a large-scale abandonment of wind po...
