Abstract

A scalable portable modular power plant that includes an electrical substation module containing a substation container with a first transformer and a second transformer positioned at the first and second ends of the substation container, and a plurality of containerized electric generator modules each positioned relative to a corner of the substation module, where each electric generator module is connected to one of the two transformers.

Claims

1. A containerized electrical substation module comprising:

an International Organization for Standardization (ISO) 40 foot high cube substation container comprising a first transformer positioned at a first end of the substation container and a second transformer positioned at a second end of the substation container, said ISO 40 foot high cube substation container including means for independently electrically connecting a plurality of electric generator modules to the first and second transformers, said electric generator modules each contained in a respective shipping container that is separate from and external to said ISO 40 foot high cube substation container,

wherein the electrical substation module is configured to generate 8MVA of apparent power, 4MVA each from the first and second transformers.

2. The containerized electrical substation module of claim 1, wherein the substation container further comprises:

two first gas insulated cubicles, each comprising at least one bay control transformer protection relay for protecting the first and the second transformers; and

two second gas insulated cubicles, each comprising at least one bay control feeder protection relay for transferring power in and out of the electrical substation module.

3. The containerized electrical substation module of claim 1, wherein each of the first transformer and the second transformer comprises at least one voltage disconnect switch for isolating electric generator modules connected to each transformer.

4. The containerized electrical substation module of claim 1, wherein the first transformer and the second transformer comprise dry type cast coil transformers configured to output up to 33 KV star at 50 hz or up to 34.5 KV star at 60 hz.

5. The containerized electrical substation module of claim 2, wherein each of the second gas insulated cubicles further comprises at least one plug-in socket for an electrical cable connection to an at least one other electrical substation module.

6. The containerized electrical substation module of claim 2, wherein the at least one bay control feeder protection relay is connected to a network switch to enable wired or wireless remote control, programming and supervision of the electrical substation module.

7. The containerized electrical substation module of claim 2, wherein the second gas insulated cubicles are positioned between the first and the second transformers.

8. The containerized electrical substation module of claim 7, wherein the gas insulated cubicles have front access inside a controller room and rear access through doors installed on an outer side of the substation container.

9. The containerized electrical substation module of claim 1, wherein the first transformer and the second transformer comprise a plurality of taps positions configured to adjust output voltage.
