3. in order to ensure the security of remote monitoring data, power carrier equipment needs to have a comprehensive network security Settings.
Wind turbine monitoring system has automatic start, stop, smooth grid-connection, two-speed switching, automatic wind, data detection and processing, fault recording and automatic protection and other local control functions of wind turbine. At the same time, it has the functions of real-time display, statistical processing of operation data, operation fault record alarm, measurement of wind speed and power characteristic curve, startup, shutdown, left and right yaw, modification of wind turbine operating parameters and other remote monitoring functions in the central monitoring room. It consists of three parts: local control part, central centralized control part and communication part. According to the application of different fans, the network communication is divided into two parts: the internal control communication part of the fan, the network communication part between the fan and the fan or the network communication part between the fan and the control center.
Power carrier industrial equipment with high real-time performance and stability is selected as network equipment.
It mainly refers to the communication between the fan engine room and the tower tower. It is responsible for monitoring the following data: 1. Power parameters include the three-phase voltage of the power grid, the three-phase current output by the generator, the frequency of the power grid and the power factor of the generator, etc. 2, wind parameters: wind speed, wind direction; 3, wind turbine state parameters: generator speed and wind turbine speed, temperature (generator, controller, bearing, speed increment oil temperature, etc.), cable torsion, mechanical brake condition, engine room vibration, oil level; 4. Feedback signal: recover interblade spoiler, release mechanical brake, release yaw brake, generator off-grid and speed drop signal after off-grid, etc.
Current internal control communication is through the fan fan between the cabin and Kentucky tend to make a pair of fiber optic transceivers, installation and maintenance of inconvenience, so kunshan electricity network science and technology special launch industrial-grade power carrier equipment, through the power line transmission signal, avoid wiring, only need a pair of equipment is very good solve such problems.
