Simulation Study on Fire Smoke and Emergency Evacuation of Personnel in the Main Plant of Underground Plant of Pumped Storage Power Station——Take a Pumped Storage Power Station in Anhui as an Example
This paper takes a pumped storage power station in Anhui as the research object,and carries out a simulation study on the fire smoke and evacuation of people in the main plant of the underground plant of the pumped storage power station.FDS and Pathfinder software were used for the simulation,and during the modeling process,the fire source,mechanical smoke exhaust facilities,number of evacuees and evacuation exits were set up according to the actual situation of the power plant.According to the simulation results,it can be seen that after a fire occurs in the main plant,the fire smoke will rise and spread to the vault of the plant,and then gradually settle down.Smoke settling will first threaten the safety of bridge engine track operators,and as the smoke continues to settle,the smoke will threaten the safety of generator floor operators.Analyzing the simulation results,we obtained the available safety evacuation time and the required safety evacuation time for the bridge engine track operators and generator layer operators in the main plant.By compared the available safety evacuation time and the required safety evacuation time,it is judged that under normal evacuation conditions,both the bridge engine track roof operators and generator layer operators in the main plant can safely complete the evacuation.
