Embodiment Construction

[0019] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0020] The present invention is mainly used for the realization method of equipment redundancy network communication function between wind turbines, booster stations, etc. in wind farms, based on the use of ring backup redundancy topology for each wind turbine to provide better redundancy Thinking, in the case of any kind of double fault node, the worst situation that occurs can only affect one wind turbine.

[0021] The communication method of the present invention aims at the single physical optical fiber ring network structure in the local control computing unit and the central monitoring unit of the wind farm, and redundantly connects the communication switching equipment, ...

Abstract

The invention discloses a redundant internet communication system of a wind turbine generator. The system comprises the components of: a first ring network and a second ring network, wherein the firstring network is connected to the second ring network through an on-site control unit of at least one wind turbine generator, the first ring network and the second ring network are both provided withconvergence layers, and the first ring network and the second ring network are both used for receiving data communication and forwarding data to the convergence layers. According to the redundant Internet communication system of the wind turbine generator, the redundancy problem under the condition of double faults is solved, and the requirements for real-time performance and rapid self-healing performance of industrial communication can be met.

Description

Technical field [0001] The present invention relates to the technical field of industrial internet, in particular to a redundant internet communication system for wind turbines. Background technique [0002] In the current practice, the wind farm communication network links the local control computing, the central control room monitoring unit and other devices through a single physical ring network, which is physically a ring network topology, but logically a chain or tree topology; The number of upstream nodes is related to equipment performance, service flow, and transmission distance. Various performance requirements and shortcomings in technical parameters directly lead to the quality of data communication. [0003] The Spanning Tree Protocol (STP) and Rapid Spanning Tree Protocol (RSTP) are commonly used in the ring network composed of Ethernet. Because the network recovery time is several seconds to tens of seconds, it cannot meet the real-time requirements of industrial netw...
