Lightning on-line monitoring system of wind driven generator

Abstract

The utility model provides a thunder and lightning online monitoring system of a wind driven generator. The thunder and lightning online monitoring system comprises a data server, a communication transmission module and a plurality of thunder and lightning monitoring units, the thunder and lightning monitoring unit is in signal connection with the data server through the communication transmission module; the thunder and lightning monitoring unit comprises a blade monitoring module, a cabin hub monitoring module and a surge protector monitoring module; the blade monitoring module, the cabin hub monitoring module and the surge protector monitoring module are respectively provided with a lightning protection device and a sensor. The lightning protection device and the sensor are installed in the blade, the surge protector and the cabin hub and used for collecting lightning current characteristic parameters when the blade, the surge protector and the cabin hub of the wind driven generator are struck by lightning and transmitting the lightning current characteristic parameters to the lightning collection unit. According to the utility model, secondary damage of the wind driven generator can be avoided, and downtime is reduced; major accidents caused by faults of the surge protection device can be avoided, and the troubleshooting cost is reduced; and lightning stroke of the blade can be monitored.
