Problems solved by technology

[0004] However, during the research and practice of the prior art, the inventors of the present invention found that the existing offshore wind farm and island micro-grid fire alarm management systems often have false alarms and missed alarms, such as no fire, However, when the fire alarm system alarms, the operators need to go to the site to verify whether there is a fire or equipment failure. Since the offshore wind farm and the island microgrid are far away from the shore, and the operators need to go there by boat or helicopter, and go back and forth. For wind farm and microgrid operation and maintenance companies, the time cost and transportation cost are very high, and are limited by the weather conditions at sea, so false alarms of the fire alarm system are an urgent problem for operation and maintenance companies
Or there has already been a fire in the offshore wind farm and the island microgrid, but the fire alarm system did not alarm, so the fire was not detected in time, and it is easy to cause the fire to expand. Due to the high cost of offshore equipment such as offshore booster stations and high engineering construction costs, Once the fire spreads to the offshore booster station, it will bring huge losses to the operation and maintenance companies of wind farms and microgrids

Abstract

The invention discloses a fire alarm management method and device for offshore wind farms and island microgrids. The method includes: performing data dimensionality reduction analysis after collecting online detection data of detection equipment in real time; storing data in the fire alarm system Historical detection database; build a fire anomaly prediction model based on historical detection data; input the online detection data collected in real time into the fire anomaly prediction model to obtain the fire anomaly prediction result, and comprehensively detect the online detection data of the detection equipment for fire The second judgment of abnormality can get the actual fire judgment result, so as to give an alarm prompt according to the fire judgment result. The present invention increases the information input of a plurality of types of sensors and cameras, constructs a fire abnormality prediction model and inputs various detection data, and conducts a comprehensive fire judgment. The accuracy of the alarm and the operation and maintenance efficiency of offshore wind power and island microgrid.

Description

technical field [0001] The invention relates to the technical field of fire early warning, in particular to a fire alarm management method and device for offshore wind farms and island microgrids. Background technique [0002] As a new stage and new direction of wind energy utilization, offshore wind power has more stable wind energy resources, more considerable development scale, more efficient power generation efficiency, more economical land use and more convenient grid access than onshore wind power. Advantage. The island microgrid can solve the power supply problem of the island very well. The joint development of the offshore wind farm and the island microgrid can realize energy complementarity, increase the proportion of clean energy, and improve the reliability of the island microgrid. Therefore, it is popular all over the world. focus on. At the same time, more and more attention has been paid to the fire alarm management of offshore wind farms and island microgri...
