Definitions

  • the present disclosure describes a containerized power supply unit having multiple drive units.
  • Such units may comprise a plurality of drive units for driving electrical generators provided in a container.
  • Containerised power supply systems are readily transportable, and can be deployed at sites at which supply of electric power to the site from a power distribution network is not available, prohibitive or insufficient for the needs at site.
  • Such generator systems may also be used where there is an absence of power networks, or indeed where a typically-used power network has been disrupted in some manner (e.g. due to acts of nature).
  • the system may be used to feed power to an existing network.
  • Such transportable generator systems may be stand alone, or may be modular in so far as the power output at site can be provided cumulatively from multiple transportable generator systems, e.g. where a single power output is provided.
  • Such generator systems can be deployed and operated from containers that meet standardised shipping container requirements (e.g. dimensions, etc.). Those containers may be modified from a standard container in so far as access panels, air inlet panels, or the like may be provided. In some cases, the generator systems may be deployed for a period of time, and then removed from site and used elsewhere.
  • standardised shipping containers are sometimes referred to as ISO containers, which have predefined sizes, shipping weight constraints, etc.
