US-Based PE Required: Protection, Control and Auxiliary Systems Review for 345kV Substation
Budget: €40 – €150 EUR
We are looking for a US-based Professional Engineer (PE) to guide and review the secondary engineering for a new 345kV, 300+ MW high-voltage substation.
Hard requirements:
Active PE license in the United States
Based in the US
Demonstrated experience with protection and control design for substations using the 1.5 circuit breaker (breaker-and-a-half) scheme, including breaker failure logic and current summation for line protection
Strong background in US utility P&C standards (IEEE C37 series, NERC PRC standards, IEEE 1818, IEEE 484)
Engagement:
Approximately 10 to 15 hours per week
Duration: 8 weeks
Remote, with scheduled review sessions
Scope of engagement:
The role is advisory and reviewing, not full execution. Our team is producing the secondary design covering protection and control, AC/DC auxiliary systems, SCADA and communications. We need a PE to guide and review:
Protection philosophy and relay scheme selection (line, bus, transformer, breaker failure)
P&C panel layouts, schematics, and wiring diagrams
AC station service design (LVAC, transfer schemes)
DC system design (battery sizing per IEEE 485, chargers, DC distribution, ground fault detection)
Control building layout and equipment arrangement
SCADA architecture, RTU/gateway configuration, and IEC 61850 / DNP3 implementation as applicable
Cable schedules, raceway design, and grounding of secondary systems
Compliance with North American utility expectations and NERC requirements
Deliverables to be reviewed:
Protection philosophy document, P&C single-lines, AC/DC single-lines, schematics and wiring diagrams, panel GA drawings, BOMs, battery sizing calculations, SCADA architecture, and a design report justifying major engineering decisions.
To apply:
Please attach CVs of the proposed engineer(s) showing relevant 1.5 circuit breaker scheme P&C experience and AC/DC auxiliary systems design on US substation projects at 230kV and above. Proposals without a CV will not be considered.
