How to use a single‑line diagram template.
- 01Choose your cogeneration topology
Select the prime mover (gas turbine, steam turbine, or reciprocating engine) and set generator voltage and power rating.
- 02Place major equipment
Add the generator, step-up and auxiliary transformers, main switchgear bus, and grid interconnection point.
- 03Configure protection and metering
Insert circuit breakers, instrument transformers, and protective relays on each generator feeder and load circuit.
- 04Connect loads and auxiliary systems
Show district or campus loads, auxiliary power, and any tie breakers for islanded or parallel operation.
- 05Generate and export
Render an editable single line diagram you can download as SVG or PNG, or continue adjusting parameters.
Questions about single‑line diagram templates
What is a cogeneration plant single line diagram?
A cogeneration plant single line diagram is a simplified electrical schematic that shows the major power equipment and connections in a combined heat and power plant—generator, transformers, switchgear, and grid tie—on a single page.
What voltage levels are typical for cogeneration plant single line diagrams?
Common generator voltages are 480 V, 4.16 kV, 6.6 kV, and 11 kV, with step-up to distribution or transmission voltage as needed. The examples on this page span these levels.
Can I use these examples as templates for my own cogeneration plant?
Yes. Each example is fully editable—you can change equipment ratings, add or remove breakers, and adjust the topology to match your site.
Do I need electrical engineering software to create a cogeneration plant SLD?
No. ChatDiagram's browser-based tool handles symbols, bus bars, and connectivity automatically; you just configure the equipment and topology.
What details should a cogeneration plant single line diagram include for a permit or interconnection application?
Typically you need generator rating, step-up transformer impedance, main breaker interrupting rating, CT/PT ratios, and the grid interconnection point with protective relays.
