Real-time wind resource visual evaluation method, system and device for in-service mountain wind power plant and storage medium

Abstract

The invention discloses a real-time wind resource visual evaluation method, system and device for an in-service mountain wind power plant and a storage medium. The method comprises the steps: obtaining the spatial position and real-time wind direction and wind speed data of existing wind measurement equipment of the in-service mountain wind power plant; in the wind resource off-line data set, finding related wind speed data under the corresponding wind direction sector; performing on-line calculation on the wind vector of the corresponding terrain clearance layer by using an internal interpolation method to obtain the current wind resource distribution of the whole wind power plant; and carrying out real-time wind resource evaluation on the in-service mountain wind power plant in a visual map form. According to the method, on the basis of the wind resource off-line data set, the evaluation thought of wind direction sector classification and wind speed interpolation is carried out in combination with field wind measurement data, on-line calculation with long working hours is avoided while the simulation precision is guaranteed, configuration of software and hardware resources in an operation and maintenance system is saved, visual output of the whole field real-time wind resources is achieved, and a theoretical reference and a data analysis basis are provided for wind turbine generator energy efficiency evaluation.

Description

technical field [0001] The invention belongs to the technical field of wind energy resource calculation in wind farms, and in particular relates to a real-time wind resource visualization evaluation method, system, equipment and storage medium for in-service mountain wind farms based on offline data sets of wind resources. Background technique [0002] Due to the vigorous development of onshore wind power in recent years mainly for geographical locations with superior wind energy resources and good construction conditions, the resources of large-scale centralized sites represented by flat terrain tend to be limited. At present, the development environment of onshore wind power has gradually shifted from flat terrain to complex mountainous areas with relatively abundant wind resources but large fluctuations. Atmospheric flow over mountain wind farms is affected by complex landforms. Local variable wind direction, intermittent wind fluctuations, and regional strong turbulence ...
