The characteristics of the wind farm have determined the location of the wind farm construction. The distance between the wind turbines must be greater than 500m. The influence of the wake of the wind turbine must also be considered. Therefore, the wind farm generally occupies a large area, has a wide distribution range, and the location is arranged. It needs to be determined based on factors such as wind measurement results and wind resource evaluation. Considering that all wind turbines may need to travel dozens of kilometers, maintenance is difficult, etc., the networking mode of wind farm communication requires high reliability, and the fiber ring network mode is generally considered. The power line of the power cable can be used to form a plurality of ring networks to complete the fiber-optic communication of the wind farm, and each fan acts as a communication node. The central monitoring system of the wind farm is generally configured in the monitoring room of the wind farm booster station and also serves as a node. Wind farm central monitoring system topology reference substation dispatching automation system, under the premise of ensuring high reliability, the minimum configuration of wind farm central monitoring system can be completed by two computers, or can be completed by several computers according to functional division, equipment includes data Acquisition server, database server, monitoring workstation, report workstation, printer, switch, etc. The data acquisition server completes the collection of data of each fan, wind tower and related substation, and at the same time completes the function of the monitoring system to issue the fan control command, generally uses the common OPC communication protocol to communicate; the database server completes the analysis, statistics and processing of the collected data. And stored in a relational database, the database generally uses a large relational database SQLSERVER or oracle; the monitoring workstation completes the human-computer interaction display of the fan and its components, the display of the fan operation and alarm information, and the operation of the operation command; The workstation completes the production and release of the wind farm report.
