Parallel Power - Scalable Power Systems

Installing two generators in parallel to operate together has two main advantages. Either they can be run together which will provide the system with twice as much power with enough supply for very demanding peak periods or the load can be switched from one generator to the other without having to switch off the entire system.

Two generators allow unexpectedly large loads or longer peak periods of demand to be covered. When the demand drops back to the normal level, only one smaller generator is required to run which is more efficient than running a larger generator with a low load.

When power is required for very long periods of time, the second generator can be started and brought 'online' to take over from the first. The first generator can then be safely switched off for maintenance purposes without having to shutdown the entire power system. If the primary power generator fails, a second generator is always available to supply the power without having to rely on a backup system with reduced capacity. This is suited for applications which may require a full energy supply in reserve.

Parallel System Benefits

  • Switch loads from one generator to the other without shutting down complete system
  • Always one generator ready to supply the system in reserve
  • One smaller generator can efficiently cover lower power demands
  • Peak periods - cover demanding peak periods by running generators together.
  • Flexible - when not enough room for a single large generator is available

Parallel Operation - Load Switching

Two Panda AC generators can be connected together to operate as one unit. This system does not feature full load-sharing capabilities for safety reasons and to keep the system simple to operate. The generators' output is synchronised and either combined or switched from one generator to the other. To increase operational safety both generators are shutdown if a system failure occurs.

Parallel Operation - Load Sharing

Fischer Panda PMGi Generators with VSCF - 'Variable Speed Constant Frequency' technology allow full load sharing capabilities. Each generator can run at a differing speed while operating in parallel. Multiple generators can be coupled and operate together as one unit.
