Abstract

Hydropower stations, as critical infrastructure for national development in China, play an essential role in electricity supply. Meanwhile, a large number of underground caverns are constructed with large fire risk threatening personnel safety. Numerical simulations on fire scenarios in hydropower stations were conducted in this study, considering fire source power, smoke exhaust volume, and fire source location. The maximum smoke temperature rise, the smoke layer height, and the vertical temperature rise of the fire source center in underground plant were analyzed. Results indicated that an increase in fire source power has a significant impact on the maximum ceiling temperature rise, and vertical temperature rise of the fire source center. In contrast, an increase in smoke exhaust rate has a smaller impact, only affecting them under conditions of high fire source power. Regarding the smoke layer height, the results showed that the influence of fire source power, smoke exhaust volume, and fire source locations was relatively small. Through a comparison of fire in the middle and at the end of the plant, it was discovered that the fire hazard under the latter location was significantly greater than that under the former location. By analyzing the smoke behavior characteristics in large space underground plant of hydropower station, this study provides a theoretical basis for adopting prevention and response measures to support fire safety in underground plant of hydropower stations.
