Fire-fighting control system and method of wind generating set

Abstract

The invention provides a fire-fighting control system and method of wind generating set. The fire-fighting control system comprises multiple fire hazard detectors, a fire-fighting controller, multiple fire extinguishing devices and a communication module, wherein the fire hazard detectors are used for detecting a fire hazard and emitting alarm information; the fire-fighting controller is used for receiving the alarm information emitted by the fire hazard detectors, and determining whether a fire behavior occurs in a fire-fighting area where certain fire hazard detector is placed according to the alarm information and preset fire behavior determining conditions; the fire extinguishing devices are used for extinguishing the fire under control of the fire-fighting controller; and the communication module is used for sending a fire alarm signal and receiving a fire-fighting control command. If the fire-fighting controller determines that the fire behavior occurs in the fire-fighting area where the fire hazard detector is placed, the fire alarm signal which indicates occurrence of the fire behavior of the wind generating set is sent to the communication module; and if the communication module receives the fire-fighting control command, the fire-fighting controller controls the corresponding fire extinguishing device to extinguish the fire according to the fire-fighting control command.

Description

technical field [0001] The invention relates to a fire control technology, in particular to a fire control system and a fire control method of a wind power generating set. Background technique [0002] There are many complex fire hazards inside the wind turbine. At present, the fire-fighting equipment or fire-fighting systems equipped in domestic wind farms may have false alarms, missed alarms, or insufficient protection areas. Sometimes they cannot effectively prevent fires, affect the normal operation of the units, or bring a lot of extra to the maintenance of wind turbines. maintenance work. [0003] First of all, the units are often installed in remote areas and are far away from the central control room. It is difficult to directly and timely obtain the fire information of the units. It is necessary to consider the communication between the fire protection system and the central monitoring room in order to grasp the working conditions of the fire protection system. ...

[0002] There are many complex fire hazards inside the wind turbine

At present, the fire-fighting equipment or fire-fighting systems equipped in domestic wind farms may have false alarms, missed alarms, or insufficient protection areas. Sometimes they cannot effectively prevent fires, affect the normal operation of the units, or bring a lot of extra to the maintenance of wind turbines. maintenance work

[0003] First of all, the unit is often installed in remote areas, far away from the central control room, it is difficult to directly and timely obtain the fire information of the unit, and it is necessary to consider the communication between the fire protection system and the central monitoring room in order to grasp the working conditions of the fire protection system

[0004] Secondly, if the staff finds that there is a fire in the unit, but the fire protection system has not yet activated at this time, it is impossible to directly activate the fire extinguishing device and extinguish the fire source through remote control.

[0005] Thirdly, the unit may generate local temperature rise, electric arc or spark during normal operation, which is a normal working phenomenon, but these situations may cause the alarm of conventional fire-fighting equipment or false activation of fire-extinguishing devices, affecting the normal operation of the unit

[0006] Finally, maintenance personnel need to climb tens of meters into the air to maintain the wind turbine cabin equipment. If a fire extinguishing device with pressure or a device with a large volume and mass are used, installation and maintenance will be very inconvenient
