Embodiment Construction

[0023] Referring now in detail to an embodiment of the present invention, an example of the embodiment is shown in the accompanying drawings, wherein the same label always refers to the same component. The following embodiments will be illustrated by reference to the accompanying drawings in order to explain the present invention.

[0024] Figure 1 Block diagram illustrating a wind farm according to an exemplary embodiment of the present invention.

[0025] Reference Figure 1 , the wind farm 10 includes at least one first wind turbine 100, at least one second wind turbine 200 and a wind farm control system 300.

[0026] Here, at least one first fan 100 may be connected to the grid via the first set of electrical lines 110, in order to transmit the generated power to the grid. In other words, the first set of electrical lines 110 may be used to connect at least one first fan 100 to the grid 20. Similarly, at least one second wind turbine 200 may be connected to the grid via a seco...

Abstract

A wind farm control system and a wind farm including the same are provided. The wind farm control system includes: a first modular multilevel converter connected to a first current collection line for connecting at least one first fan to a power grid and configured to control power transmission of the first current collection line; and the second modular multilevel converter is connected to the second current collection circuit and is configured to control power transmission of the second current collection circuit, the second current collection circuit is used for connecting at least one second fan to the power grid, and the first modular multilevel converter and the second modular multilevel converter are connected together through a direct current end.

Description

Technical field [0001] The present invention relates to the field of wind power generation, more particularly, to a wind farm control system and a wind farm comprising a wind farm control system. Background [0002] Wind energy is a clean renewable resource, and its use is increasingly valued by countries around the world. With the development of the world energy crisis, how to effectively use wind energy for power generation has become a hot spot in social development. [0003] However, in wind farms, there is often a problem that the grid of convergence access points is weak, and after passing through a longer collector line, the wind turbine is in the power grid, and the grid of the access point is weaker, and there are problems such as difficulty in grid connection and easy off-grid. Contents of the Invention [0004] Object of the present invention is to provide a wind farm control system and a wind farm comprising a wind farm control system. [0005] One aspect of the pres...
