Can you afford to find out when a component fails, that it is obsolete or unrepairable?
DVL has decades of knowledge in designing and supplying innovative, highly reliable, electrical control systems for switchgear, generator systems, UPS systems and wherever maximum reliability is required. This starts at the programmable logic controller (PLC), but equally includes generator controllers and synchronizers, protective relays, power quality devices, and every other item and detail that makes up a “rock solid” electrical control.
A substantial amount of the basic “building blocks” of electrical control systems are now becoming “mature” and are not supported, or have become obsolete. GE has obsoleted most of its popular 9030 line of PLCs, Woodward has done the same with its DSLCs and MSLCs, and there is an extensive obsolescence list.
DVL Group has been offering total control systems upgrades (hardware, software, and HMI graphics), not only on DVL supplied switchgear, but on all other manufacturers’ equipment as well. We have performed these services on all four of the major switchgear OEMs as well as all of the leading Generator switchgear control OEMS. Our control experience includes GE, Allen Bradley, Woodward, Basler, Siemens, Modicon, Caterpillar, Onan, Generac, and many other leading manufacturers.
Considerations for a Controls Upgrade
The Controls upgrade is so much more than “just replacing components.” These are the “DVL Baker’s Dozen” extra considerations to account for:
1. Are all the control components looked at for obsolescence or performance reasons?
2. Does the system have a Human Machine Interface (HMI), does it need upgrading, enhancements, can it be more informative, helpful, or intuitive?
3. Will the new components fit in the old spaces, and how can we minimize control wiring disruption?
4. Can we perform this upgrade while keeping a “minimum number” of generators ready for service? What are the “creative” options here?
5. Do we have a simplex PLC system and does it make sense to upgrade to redundant systems?
6. Are there “as builts” of the existing system? If so, are they accurate? Does the existing documentation need to be updated or does a new set need to be generated from scratch?
7. Is the system sequence of operational fully documented and understood? Is it optimized, and can we improve it?
8. Will your service provider provide significantly detailed Methods of Procedures (MOPs)? What about the testing and commissioning script ahead of time for the team to review?
9. Are there interfaces to the building BMS, SCADA, and EPMS systems? Will they still work as before, or do they need to be optimized?
10. Is an experienced and knowledgeable Project Manager required, in addition to the Engineers performing the upgrades, to ensure a smooth and timely project completion?
11. Should other upgrades also be considered such as hardening the controls critical power transfer scheme (86 scheme), replacing older analog protective relays, generator synchronizers and control devices, etc.?
12. Are the power meters now obsolete? Do you want to upgrade them to “transient capture” meters for enhanced PQ analysis?
13. Are the circuit breakers obsolete? DVL can supply full assembler that is simply built into the existing cells for all major breaker manufacturers.
What Top Clients are Saying About Us
"Personally and professionally I wanted to thank DVL and the team for their outstanding effort for the Generator PLC migration at [our facility] this past week. There was an incredible amount of work done in a very short amount of time. Most persons will never understand what it took to accomplish what was done. The complexity and sheer number of connections was staggering. So many elements of leadership, commitment, teamwork, persistence, and determination were shown throughout the entire process. My words simply don’t reflect my heartfelt thank you for a job done extremely well."
