Problems solved by technology

[0008] However, circuit breakers have been used in power plants for many years because possible damage to wind turbines was considered less important than damage to the grid that could be caused by a short circuit

Embodiment Construction

[0037] In the following, only exemplary embodiments of the present invention are described. These embodiments are presently to the applicant the best mode of carrying out the invention, but they are not the only way to carry out the invention.

[0038] Here, the invention is described with reference to a wind turbine generator, although it may be implemented with any generator system.

[0039] Regarding the attached drawings, figure 1 A schematic diagram of the exterior of a conventional wind turbine generator 2 is shown. figure 1 The wind turbine rotor 4 connected to the main shaft 6 of the wind turbine 2 is shown. The nacelle 8 is in turn supported by the wind turbine tower 10 . The nacelle 8 and tower 10 house most of the components of the wind turbine, including the wind turbine or generator controller 16 , which is a computer processor arranged to control the operation of the wind turbine 2 . The controller 16 controls all equipment in the wind turbine 2 based on in...

Abstract

The present invention relates to a method of operating of a wind power plant comprising a circuit breaker and at least one wind turbine generator electrically connectable to an electrical grid through said circuit breaker, the method comprising the steps of detecting at least one condition for the circuit breaker to trip by means of a sensor; informing a control means of this detection prior to the circuit breaker disconnecting; and preparing the at least one wind turbine generator before said circuit breaker disconnects said at least one wind turbine generator from said electrical grid.

Description

technical field [0001] The present invention relates to a wind power plant comprising a circuit breaker and at least one wind turbine generator and its operation. The present invention relates particularly, but not exclusively, to wind power plant circuits. Background technique [0002] In the power generation industry, electrical energy generating turbines are used to generate electrical energy for delivery to a consumer supply network called the grid. Each form of turbine presents its own problems in manufacturing and operating. For example, wind turbines are often erected in clusters, known as wind power plants or wind farms, at multiple locations that have undergone a rigorous selection process. This selection process typically places wind turbine farms at significant distances from the end users of the electrical energy they generate. [0003] The individual wind turbines are usually grouped into multiple wind turbines, collectively referred to as feeder lines, from ...
