Abstract

The invention discloses a method for improving reliability of a wind prediction system by use of a double-redundancy mode. The method comprises: two wind power prediction systems are arranged in a station; two wind measuring towers are arranged at the place of a wind power plant, each wind measuring tower is provided with two measuring devices, and thus data redundancy is realized. The invention further provides a system for improving reliability of a wind prediction system by use of a double-redundancy mode. The system comprises twp wind power predication systems and two wind measuring towers, wherein each wind measuring tower is provided with two measuring devices. According to the invention, through arrangement of double-redundancy wind measuring tower equipment and internal and external network servers in double-redundancy configuration, timely acquisition and transmission of acquisition data and sending data are guaranteed, at the same time, the stability and safety of a transmission line are ensured, the stability, the accuracy and the uploading rate of uploading data are finally improved; predication data can be manually modified; and an alarm function is exhibited, an early warming can be timely given, and property loss can be avoided.

Description

technical field [0001] The invention belongs to the technical field of wind power forecasting, and in particular relates to a method and system for improving the reliability of a wind forecasting system by using a double redundancy method. Background technique [0002] As a clean renewable energy, wind energy has the advantages of low environmental impact, abundant resources, and high conversion efficiency. The development and utilization of wind energy has gradually become the most important development direction of renewable energy in China. However, due to the characteristics of strong intermittent, high randomness, and weak dispatchability of wind power and other renewable energy power generation, large-scale connection will have a greater impact on the operation of the power grid, and it is suitable for the construction of local power grids in large-scale wind farm areas. Therefore, in order to ensure the safety and stability of the grid operation, it is sometimes neces...
