Wind speed and wind direction sharing system of wind electric field set

Abstract

The invention relates to a wind speed and wind direction sharing system of a wind electric field set, which belongs to the technical field of wind driven generation. The technical scheme includes relating meteorological information of each wind generating set to wind speed and wind direction meteorological information of a plurality of sets and / or wind electric field booster stations on the periphery with similar positions and topography according to relevant positions and topography of each wind driven generating set in the wind electric field; sharing the meteorological information of the relevant wind generating set under special conditions by means of a wind electric field supervisory control and data acquisition (SCADA) system; automatically achieving automatic switch of local meteorological information and remote shared meteorological information by a fault set local control system; simultaneously performing backup protection on safety operation of the set under strong wind operation mode based on an pitch angle and generated output, and finally ensuring continuous and safe operation of the set. The wind speed and wind direction sharing system of the wind electric field set can well solve the problem that a machine is halted while the wind generating set continues generating power due to faults of a wind speed and / or a wind direction sensor and is simple in structure, high in safety, strong in practicality and good in economy.

Description

technical field [0001] The invention relates to a wind speed and wind direction sharing system for wind farm units, which belongs to the technical field of wind power generation. Background technique [0002] At present, large-scale wind turbines are based on the wind speed and wind direction information measured by the unit itself, and are controlled by the control system to realize unit input, power generation operation, cut-out and automatic yaw to the wind. The wind speed and wind direction sensors are located on the top of the nacelle, and due to the influence of harsh environments such as ice, snow, freezing rain, sand and dust, the failure rate is relatively high. When the wind speed and wind direction sensors fail, the unit stops and cannot continue to run, and these sensors cannot be repaired or replaced in snowy, rainy, or windy weather, which will cause a large loss of power generation for users.
