Abstract

The invention provides a method for operating a wind power electric field power network system, especially a method for conducting networking in an electric field management system, i.e. an electric field main station and each wind power turbine, i.e. WKA through a central network. The central network is used for conducting a bidirectional data transmission and is implemented as a circular net. Based on an OSI hierarchical model (42-48), data is transmitted from a first layer which is a data physical layer and a hardware layer (42) to a second layer, i.e. Ethernet or Isonet controller (43). An IP layer, i.e. a third layer of the OSI model, a UDP / TCP layer, i.e. a fourth layer of the OSI model, and a RPC layer, i.e. a fifth layer of the OSI model are connected in a manner of bridge joint through a WPP real-time drive (49). A direct connection of the WPP real-time drive (49) is formed between the second layer, i.e. the Ethernet or the Isonet controller (43) and a seventh layer, i.e. a WPP application (48).

Description

technical field

[0001] The present invention relates to a method and device for operating the power grid system of a wind power plant, specifically, to a method and a device for operating the power grid system of a wind power plant through a central network The method of networking, wherein. This central network is used for bidirectional data transmission and usually takes the form of a ring network. Background technique

[0002] · On the way to the successful deployment of renewable energy sources worldwide, especially the intensive use of wind energy, there is an increasing need for energy supply companies (EVUs) to communicate with wind farms.

[0003] • A wind farm may consist of several hundred wind turbines (=slaves), where the wind farm is monitored and controlled by a power plant master. The farm master thus has the function of supplying data to the slaves (ie programmable control) of each wind turbine at specific time intervals (periods).
