Modular Plants

The OnPower Electric Modular Power Plant is designed to supply energy to remote areas, such as isolated rural communities, mining, oil rigs, post-storm sites, earthquakes, etc., or areas where conventional power supply does not exist.

It is supplied in a 20- or 40-foot ISO maritime container with noise

control and configured by a set of integrated units with each other and capable of generating medium voltage power for the local power distribution system, and these power supply units are defined as:

  • Generating units
  • Cooling unit
  • Distribution unit
  • Transformer

In the internal part of the container base, are installed embedded tanks between a double wall for the containment of contaminated oil/water, while in the cabin comprising the cooling unit, air inlets are provided which aid in the cooling and at least one pair of fans.

The OnPower Electric Modular Plant can be assembled with four or two generators, which, in its turn are powered by natural gas, automotive diesel or biodiesel engines, and each generator is coupled to a gas exhaust pipe that is installed in the top wall of the container. This configuration allows the distribution of charge between generators, increasing the efficiency in the relation of fuel consumption x KWe, besides the useful life of the engines.

Measurement

  • Generator voltage (Three-phase/4-wire)
  • Generator current (3 true RMS values)
  • Mains voltage (Three-phase/4-wire)
  • Mains or ground current (1 true RMS value, mains or ground current selectable)
