Substation Voltage Optimization
Our team provided engineering support for a Major Utilities Substation Voltage optimization project. This project was initiated to meet the updated industrial standards, as well as to provide feeder metering functionality. For existing conditions, Solved Engineering performed field surveys and DC battery calculations.
Development of a high voltage and low voltage corrective plan was also completed. On the low voltage side, transformer and feeder meter upgrades aim to include: Supervisory Control and Data Acquisition Systems (SCADA), communications, and 3-phase kW & kVAR hourly metering. On the high voltage side, Station transformer load tap changer (LTC) controls, and capacitor controls were upgraded to be compatible with distribution voltage optimization central control systems. The design included 3-phase voltage regulators to supply superior quality in electric service.
This project was ultimately a pilot project with the aim of a much larger goal. The purpose is to provide greater accuracy in customer’s kW per hour metering, which will fundamentally protect customers from higher electricity bills going into the future.
We are the industry experts in Beckwith Load Tap Changer Control retrofits and new installation. We are trained by Beckwith Electric to provide these services. There is no other in the industry that has Ph.D. credentials and DBE certified to offer these solutions in the Licensed Electrical Engineer space.
Two (2) 69kV Circuit Breaker Replacement National City CA Substation
Our team provided consulting for San Diego Gas & Electric (SDG&E) for the replacement of Two (2) 69kV Circuit Breakers. In addition, wiring for SEL-351S and various other protective relays for this location. Our Engineers and CAD operators have experience in working with SDG&E Standards and applying them to one-line diagrams, control, wiring, and AC/DC schematics. Our client has dynamic standards that acquire attention to detail and request for flexible consulting solutions that are customized to the SDG&E system.

Beckwith 2001D Relay Upgrades for Parallel Transformer LTC Control
Feeder relay and metering upgrade for multiple Substations
Transmission Line Planning and Consulting
Our team is currently providing Staff Augmentation solutions at SDG&E for Substation Technician. In addition we are providing a Protection & Controls Engineer for staffing solutions at PowerWright Technologies on Ameren projects
Our team supported the upgrade of a Substation Communication network in the Ameren territory to Fiber Optic. Our engineers upgraded the communication equipment, and AC and DC auxiliary power system. Utilizing client and industry standards, our team updated schematics, and performed both AC system sizing calculations and DC system sizing calculations. Our team collaborated with the client, and made recommendations to ensure equipment selection and system design has been optimized for the client's needs.
San Diego Gas & Electric (SDG&E)
Support for San Diego Gas & Electric (SDG&E) on their Fire Risk Mitigation project (FiRM) for overhead distribution lines. Engineering and PLS-CADD design was performed for the hardening projects for the overhead 12kV distribution system. The team has performed design, PLS-CADD modeling, and quality assurance reviews of multiple 12kV circuits for the replacement of wood poles with steel poles, and the replacement of copper wire. This is a distribution hardening project for the area's most at risk for wildfires in efforts to provide safe and reliable energy for a critical service territory.
