This mid‑level role targets a professional with 5–10 years of experience who brings rigorous electrical engineering fundamentals and the applied interest to translate that knowledge into high‑fidelity simulation models that de‑risk commissioning and validate design decisions before field equipment is energized.\n\nLocation\nHybrid in the United States with ~25% travel to client sites\n\nResponsibilities\nElectrical Power Systems Modeling and Dynamic Model Development – Build physics‑based dynamic models spanning the full power path—from utility supply or on‑site generation through switchgear and distribution to load endpoints. Represent key equipment characteristics including rotational inertia, governor type and response, droop control, alternator winding parameters, ATS transfer timing, UPS topology and bypass logic, and branch circuit coordination.\n\nRotating Machinery & Generation – Develop models of reciprocating engine‑generators, combustion turbines, and hybrid generation configurations. Accurately represent governor and AVR behavior, paralleling switchgear synchronization, load‑sharing characteristics, and generation source interactions during paralleling, load transfer, and unit trip events. Model BESS grid‑forming and frequency/voltage response behavior where applicable.\n\nTransient, Harmonic & Protection Analysis – Model transients and power quality phenomena including voltage and frequency deviation during transfer events, RoCoF under generation loss, THD under non‑linear loading, and UPS waveform degradation during fault events. Model protection relay coordination, overcurrent device selectivity, and breaker trip/reclose logic. Evaluate outputs against applicable standards including ITIC/CBEMA and IEEE 519.\n\nUse Case Development & Simulation Execution\n\nContingency & Fault Simulation – Develop and execute N‑1/N‑2 contingency scenarios, ATS open‑ and closed‑transition transfer scenarios, and UPS power path fault scenarios. Assess power margin, overload duration, waveform quality, ride‑through behavior, and load transfer success against defined acceptance criteria. Design cascading multi‑system fault scenarios to evaluate failure behavior, alarm escalation logic, and load shedding sequences.\n\nBlack‑Start Sequencing – Model and execute complete startup from de‑energized conditions, sequencing generation ignition, governor stabilization, switchgear closure with synchronization verification, UPS initialization, and load energization. Identify automation gaps, validate interlock release logic, and document the full sequence timeline from de‑energized conditions to stable generation and load acceptance.\n\nCapacity & Expansion Envelope Analysis – Model phased expansion scenarios to evaluate whether planned electrical infrastructure can support incremental load additions with acceptable redundancy margins. Produce headroom analyses, uptime projections, and fuel‑limited runtime assessments to support go/no‑go decisions at each expansion milestone.\n\nControl Logic Validation & Commissioning Support\n\nSequence of Operations Validation – Simulate and validate programmed electrical control sequences—ATS transfer logic, generator paralleling and synchronization, and UPS redundancy and bypass sequences—against project control narratives and design intent. Document pass/fail results against a defined test matrix.\n\nControl System Testing – Support integration of PLC logic into the simulation environment and execute control system factory acceptance testing against live or emulated controllers. Identify control logic deficiencies, coordinate corrective actions, and retest updated logic prior to field deployment.\n\nInterlock & Protection Validation – Validate interlock release conditions, protection relay logic, alarm propagation, and emergency shutdown sequences. Confirm that safety‑critical automation functions correctly without manual intervention under simulated fault and contingency conditions.\n\nArchitecture Assessment, Reporting & Practice Development\n\nArchitecture Review & Gap Analysis – Review project electrical documentation—one‑line diagrams, protection coordination studies, I/O lists, control narratives, and EPMS configurations—to assess instrumentation coverage and data availability. Identify metering and instrumentation gaps and recommend remediation strategies.\n\nTechnical Reporting – Develop simulation reports documenting use case findings, failure scenario results, SOO validation outcomes, and performance compliance analyses. Produce quantitative outputs—power efficiency predictions, capacity margins, fuel runtime assessments, and protection coordination evaluations—with stated confidence intervals and documented assumptions. Contribute to operator training materials and model handover documentation.\n\nPractice Contribution – Contribute to reusable model libraries, simulation methodologies, and standardized testing frameworks. Support technical scoping and proposal development for new simulation opportunities.
