Super-high-rise buildings are characterized by high population density, numerous electrical appliances, complex power supply systems, and long vertical transportation distances. They are often located in urban core areas, where there are extremely high demands for power continuity and safety. In the event of a mains power failure, the normal operation of vertical transportation systems (such as elevators), firefighting and life safety systems, building automation, and security systems can be directly affected. This may lead to serious consequences, including personnel being trapped, increased safety risks, and operational disruptions. Therefore, backup power systems must possess the capability for rapid response, high reliability, low noise emissions, flexible grid integration, and adaptability to complex power distribution structures, while also meeting the stringent requirements of urban environmental protection and spatial constraints.ng.
