Automatic firefighting control system of wind turbine generator system

Abstract

The invention discloses an automatic firefighting control system of a wind turbine generator system. The automatic firefighting control system is characterized by comprising an air-breathing type smoke-sensitive fire hazard detection alarm device, a firefighting monitoring device, an automatic fire extinguishing device and a shared fireproof plugging device, wherein the air-breathing type smoke-sensitive fire hazard detection alarm device comprises an air-breathing type smoke-sensitive fire hazard detector and a sampling pipeline in match; the firefighting monitoring device is arranged in a central control center of a wind power plant; the automatic fire extinguishing device comprises an automatic pulse type dry powder fire extinguishing device and an automatic aerosol fire extinguishing device for achieving total flooding fire extinguishment protection; the special firefighting plugging device is arranged at the connection part of a wind turbine generator system cabin and a tower cylinder. The automatic firefighting control system of the wind turbine generator system can sample at real time, analyze by self and determine the alarm grade automatically, so that working personnel can master the fire hazard progress at real time, accurate and reliable firefighting measures can be taken according to the alarm grade, and due to complete information self-provision and self-analysis capability, the firefighting management can be correctly and orderly executed.

Description

technical field [0001] The invention relates to a fire-fighting system, in particular to an automatic fire-fighting control system for a wind power generating set in the wind power field. Background technique [0002] As a clean and renewable new energy, wind energy has been paid more and more attention by countries all over the world. At present, with the rapid development of wind power generation technology, safety accidents continue to occur, among which fire accidents account for a large proportion, and fire accidents have caused huge economic losses to the wind power industry. [0003] Wind turbines are generally installed in relatively remote places, far away from fire rescue centers, and some wind turbines are even installed at sea, which makes it difficult to supply fire supplies in time, causing certain difficulties in fire rescue. In addition, the height of wind turbines is generally 70-100 meters, and when a fire accident occurs, the temperature of the ignition p...

Problems solved by technology

[0005] In order to overcome the problems caused by wind turbine fires, Chinese patent application No. 2009100352014 discloses a wind turbine cabin fire automatic measurement and control and emergency system. Difficulties need to be solved urgently, reflected in: First, there is no reasonable fire alarm level and fire mode under each fire alarm level, and the corresponding fire mode cannot be executed immediately according to the fire parameter value

Second, the firefighting system only uses an inert gas fire extinguishing system, and does not use corresponding fire extinguishing substances for different components of the wind turbine. At the same time, the inert gas can easily suffocate people and cause other physiological hazards

Third, the detectors used are temperature sensors, smoke sensors and oxygen concentration sensors, so the sensitivity is not high enough

Fourth, it is impossible to accurately find the source of the fire during the remote monitoring of the fire and carry out targeted fire fighting according to the severity of the fire in different parts of the wind turbine cabin, and there is no mention of controlling the jet flow rate of the fire extinguishing material
