I. Overview
The wind farm unit monitoring system is responsible for real-time monitoring of the operating data, status, protection device actions, and fault alarms of numerous wind turbines within the wind farm, and remote control, data logging, data reporting, and curve generation of the wind turbine. Wait. In the wind turbine monitoring system, the central monitoring system operates on the upper computer (server) located in the central control room (boost station central control room) and passes through the lower machine (fan control) of each wind turbine dispersed in the wind farm. (Communication) to realize the cluster monitoring of the whole wind turbine.
Second, the wind farm unit monitoring communication system networking requirements
The company plans to build a wind power project with a scale of 800,000 kilowatts in Northeast China. The wind farm will build 36 sets of 1.5MW wind turbines. The monitoring center server of the wind farm monitoring system will be located in the booster station central control room. Each fan controller provides Ethernet. interface.
The reliability of communication between the wind farm central monitoring machine and the wind turbine on-site control system is very important, and it will directly affect the reliable operation of the entire wind farm monitoring system. Considering the poor geographical environment of the wind farm project, the wind farm is built in an open area, easily subject to strong lightning strikes, the local climate environment is rather harsh, and the mechanical vibration and electromagnetic radiation of the wind power equipment itself are large, so the monitoring system Communication equipment requires high reliability.
This project adopts Aobo Communication Industrial Ethernet to solve the transmission problem of control communication. Each AOBO 5023S optical fiber self-healing ring industrial Ethernet switch is placed in the ground control box of each fan and the central control room of the booster station, a total of 39 sets. Three reliable fiber self-healing double ring networks are formed. Aobo Communication's AOBO 5 series of industrial Ethernet switches have a self-healing ring network function. Using ABRing ® patented technology, it can achieve rapid ring network self-healing switching when a communication fiber or switch in a ring network fails due to various reasons. Realize reliable communication, ring network self-healing time is less than 100ms; AOBO 5 series of industrial Ethernet switches designed for harsh climate and industrial use environment, in the environment adaptability, anti-electromagnetic interference, lightning protection and communication reliability can meet Claim.
