Operation control method for parallel variable-speed constant-frequency wind generator set

Abstract

An operation control method of a synchronization variable speed constant frequency wind generating set includes the strategies of AYC, synchronization control, low wind speed ceiling capacity follow control and high wind speed constant power control which includes the AYC, the synchronization control, the low wind speed ceiling capacity follow control and the high wind speed constant power control. An anemoscope and a wind vane measure the wind speed and wind direction information to generate a yaw deviation signal; a yaw motor is driven to execute left and right yaw according to the yaw direction and angle and limit the yaw velocity and meanwhile, the steering turns of the engine room are measured with the help of cables winding around a sensor, so as to execute safe untwist action, thus ensuring that the wind generating set realizes quick, accurate and safe effect of the wind wheel against wind. All the control strategies cooperate in work from the start to synchronization power generation according to the requirement of the set and external conditions, so as to ensure the safe and efficient operation of the wind generating set.

Description

technical field [0001] The invention relates to an operation control method of a grid-connected wind power generator set, which is suitable for grid-connected operation of wind power generators of various capacity models, and belongs to the field of new energy and automatic control. Background technique [0002] With the rapid development of the economy, the consumption of energy is increasing year by year, and the conventional energy resources are facing the dilemma of depletion day by day. There is an urgent need for some clean, pollution-free and renewable new energy sources. Wind energy is a clean and sustainable energy.

Problems solved by technology

[0004] Although my country's wind power industry is developing rapidly, there is a big gap in wind power generator manufacturing technology and wind power control technology compared with wind power developed countries.

Advanced wind power technologies such as large-scale wind turbines, active stall control, variable pitch control, variable speed constant frequency and other advanced wind power technologies still need further research and application, and the design and production technology of variable pitch units and variable speed constant frequency controllers are still in the stage of technology development
