Load reducing system of wind generator set and working method of load reducing system

Abstract

The invention discloses a load reducing system of a wind generator set and a working method of the load reducing system. The system comprises a machine readable storage device, display equipment, a display adapter, input equipment, sensors, a processor, a peripheral interface, a memory and network interface equipment, wherein the machine readable storage device, the display adapter, the input equipment, the sensors, the processor, the peripheral interface, the memory and the network interface equipment are in communication through a bus, the display equipment is in communication with the bus through the display adapter, and the network interface equipment is in communication with remote equipment through a network. The method includes the steps of inputting initial data, collecting parameters of all the sensors, selecting an operating mode and controlling a fan to enter the selected mode. According to the system and the method, various parameters in the operating process of the fan are collected, a variable pitch system, a yaw system, a braking system and the like are integrated, the structural load of the fan is effectively reduced, and the limitation of independent operation of the systems on reduction of the structural load is avoided.

Description

technical field [0001] The invention belongs to the field of fan control, and in particular relates to a load reduction system of a wind turbine and a working method thereof. Background technique [0002] Existing wind turbines use many control systems. The control systems used to reduce the wind turbine load include pitch control system, power converter control system, brake control system, yaw control system, etc. The wind turbine uses these systems to control the speed of the wind rotor. As well as limiting structural loads that increase under specific environmental and operating conditions. Although these control systems are all used to control the load of the wind turbine, their control methods are independent and there is no coordination between them. For example, the pitch control system or yaw control system is used alone, which leads to the inability to achieve the best load reduction. Effect. For example, the yaw control system is the control system with the most...

Problems solved by technology

Although these control systems are all used to control the load of the wind turbine, their control methods are independent and there is no coordination between them. For example, the pitch control system or yaw control system is used alone, which leads to the inability to achieve the best load reduction. Effect

For example, the yaw control system is the control system with the most obvious load reduction effect among these control systems. To some extent, it can reduce the structural load on the foundation of the blade, drive chain, and tower, but it cannot quickly respond to the wind. To avoid those structural loads that cause damage to the wind turbine; to achieve the maximum load reduction effect, you need to use other control systems, but the yaw control system cannot control other control systems
