Woodward Easygen vs PLC control system

[meehd88]

I am a facility owner currently working on replacing our genset and paralleling switchgear with 6 x 2.5MW CAT 3516c and am being presented with some options on the controls side.

Option 1 - Woodward Easy Gen + SEL 700G for UV/OV protection, sync check
Option 2 - CAT OEM EGP paralleling controls
Option 3 - Russelectric with Allen Bradly PLC + SEL 700G

I am looking for feedback on the options above in terms of reliability and would like to see if there are better options out there today. Main concern is reliability and serviceability. Cost is less of a issue.

I can't speak to the other units but I've been very happy with the SEL products.

My personal preference on any of this is go dedicated hardware rather than a PLC. For the examples you've provided this would mean the EasyGen option.
The previous Woodward model was the default standard for quite a few remote power stations I'd been involved in. I've not used them but the EasyGen also comes in a full redundant controller option if required.
SEL makes good equipment too, and has excellent support.

The Caterpillar advantage is their local dealer network. Same day service is often available.

The Caterpillar disadvantage is that you may need to take advantage of that service. The OEM packages have to be more inclusive of a broader range of requirements so they tend to be more complicated as a result.
