[0073] The method includes the following steps (taking the first embodiment as an example):

[0074] Step 1. By analyzing the meteorological and topographic conditions of the area, the occurrence of the wind farm output power climbing event is mainly affected by wind speed, wind direction and time period, so the measured output of the wind farm for a continuous year with a time interval of 5 minutes is extracted Time series of power data and wind speed and wind direction; through verification and correction of the original data, a series of time series of wind farm output power, wind speed and wind direction at equal time intervals are obtained as input sample time series.

[0075] Step 101, data verification: read the measured output power data and wind speed and wind direction data of the wind farm, and select unreasonable data and missed data;

[0076] Step 102, data correction: use the algebraic difference method to correct the data selected in step 11 to form a sequence o...

Abstract

The invention belongs to the technical field of wind power generation, and especially relates to a system and a method for predicting a wind farm output power climbing event. The system comprises a data reading module, an experiment module, a wind farm output power climbing event influencing factor analysis module, and a wind farm output power climbing event predicting and warning module. The method comprises the following steps: acquiring parameter information related to a wind power climbing event, and designing experiments to explore the way in which each factor influences the wind power climbing event, the order of priority of the factors, and the horizontal combination of the factors under the greatest risk of wind power climbing; selecting model input and optimizing a prediction model according to the order of priority of the factors to improve the prediction accuracy greatly; and providing wind power climbing event alarm for the power system according to the horizontal combination of the factors under the greatest risk of wind power climbing. The wind power climbing event prediction system provided by the invention is universal, the model input can be optimized for all wind plants, and the prediction accuracy is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of wind power generation and its grid connection, and in particular relates to a system and method for predicting a ramp event of output electric power of a wind farm. Background technique [0002] With the increasing scale of wind power grid connection, the impact of wind power fluctuations on the grid cannot be ignored. Especially in power systems with a high proportion of wind power, large fluctuations in wind power output power in a short period of time (ie, wind power ramp events) have seriously threatened the safe and stable operation of the power system, directly causing economic losses to the power grid, and seriously It will affect the balance of power generation in the power system, and even cause large-scale blackouts. In order to reduce the impact of wind power ramp events on the stability of the power system, improve the grid-connected characteristics of wind power, timely and accurately predic...
