Arrangement method of modular ventilation system for underground substation

With the continuous economic development and the scale expansion in cities, the construction of underground substation has become one of the practical solutions to solve the urban land use. Discusses the reasonable design of ventilation system in the underground substation, and proposes the arrangement method of modular ventilation system according to a practical engineering. The results show that it not only ensures the reliable operation of the underground substation, but also saves space and reduces the life cycle cost.
