Embodiment Construction

[0026] figure 1 A schematic block diagram of an operations management system 1 according to an embodiment of the invention is shown. The operations management system 1 enables optimal coordination between the component modules 4 and the damping modules 5 of the wind energy installation. For this purpose, the damping module 5 has, for example, an ABS soft brake, an electronic control device for the generator and frequency converter, an active torque support and an IPC (Individual Pitch Control) module. The damping modules are coordinated by means of the operations management system 1 of the wind energy installation with component modules 4 in such a way that the onset of natural vibrations in the wind energy installation is suppressed even under extreme wind conditions such that the wind energy installation Work with high energy production efficiency and not get stuck in natural vibration state.

[0027] For this purpose, the wind energy installation has a large number of sen...

Abstract

The invention relates to a management system (1) for a wind energy plant (2), comprising at least one control unit (3), and to a method using the management system (1). The management system (1) is used to coordinate component modules (4) of the wind energy plant (2) with vibration damping modules (5) and / or load reduction modules, wherein a sensor system (6) supplies data of the operating states of the component modules (4) for a system analysis (7).; For this purpose, reactive vibrations and / or predictive forecasts of vibrations of the wind energy plant (2), and predictive disturbance variables are registered, and the vibration damping modules (5) and / or load reduction modules in the control unit (3) are activated, wherein an actuator (8) carries out damping measures and / or load reduction measures on the component modules (4) in accordance with the vibration damping modules (5) and / or load reduction modules of the control unit (3).

Description

technical field [0001] The invention relates to an operation management system for a wind energy installation having at least one controller and to a method performed using the operation management system. The operation management system is used to coordinate the component modules of the wind energy installation, which are capable of reducing loads or damping vibrations, wherein the sensor system provides the operation management system with data on the operating state of the component modules. Background technique [0002] Wind energy installations have a large number of sensors which, for example, predictively detect the wind field, analyze the load on the blades, check the load on the main shaft, measure the reaction to torque peaks, monitor the state of the transmission and measure the electrical parameters. At the same time, modern wind energy equipment provides a variety of devices such as pitch drive system, azimuth drive system, braking system and active torque supp...
