A fire control system and control method for a wind turbine room

Abstract

The invention discloses a wind power generator room firefighting control system. The wind power generator room firefighting control system comprises a wireless sensor network, a gas storage module, afirefighting module, a device control module and a control platform, wherein the wireless sensor network is arranged in a wind power generator room and used for detecting temperature, smoke concentration, oxygen concentration, fire existence and abnormal position in the room; the gas storage module is used for storing carbon dioxide gas; the firefighting module is connected with the gas storage module and used for driving the gas storage module to release carbon dioxide; the device control module is connected with a wind power generator unit and used for controlling the on-off of the power supply of the wind power generator unit; and the control platform is connected with the wireless sensor network, the firefighting module and the device control module and used for receiving detection data of the wireless sensor network and controlling the work of the firefighting module and the device control module. The invention also provides a control method of the wind power generator room firefighting control system. When the wind power generator room is in operation, a working state of an alarming module and the firefighting module are determined on the basis of a BP neural network, so thatthe firefighting safety in the room can be improved.

Description

technical field [0001] The invention relates to the technical field of fire monitoring, and more specifically, the invention relates to a fire control system and control method for a wind turbine room. Background technique [0002] Wind power generation mainly depends on wind turbines and their control systems. The wind turbine and its main control system are installed in the nacelle at the top of the wind power tower more than 60 meters above the ground. The whole nacelle can be called the heart and brain of the wind turbine. Since the wind turbine will generate high heat during operation, when the heat dissipation is not smooth, or the unit fails and the heat generated is higher than the heat dissipation capacity, the accumulated heat will cause the temperature of the unit to rise rapidly. If the temperature rise cannot be detected and stopped in time , when the temperature exceeds the resistance point of the motor, the light one will cause the wind turbine or the control...

AI Technical Summary

Problems solved by technology

Since the wind turbine will generate high heat during operation, when the heat dissipation is not smooth, or the unit fails and the heat generated is higher than the heat dissipation capacity, the accumulated heat will cause the temperature of the unit to rise rapidly. If the temperature rise cannot be detected and stopped in time , when the temperature exceeds the hot spot of the motor, the light one will cause the wind turbine or the control system to fail, and the gear oil in the gearbox may also leak

In severe cases, combustibles such as cables in the engine room or leaked gear oil in the electrical appliances of the control system will be ignited, causing a fire.

In related technologies, the running wind turbines basically lack emergency devices for active and automatic measurement and control and fire protection in the cabin.
