Technical Scope & Engineering Capabilities
MEPCO Engineering Projects brings specialized domain knowledge, rigorous modeling standards, and practical site experience to every assignment. Our scope covers:
- Network Performance and Protection: Load flow analysis, voltage regulation, reactive power dispatch, short circuit analysis (IEC 60909 / ANSI IEEE), numerical protection coordination, motor starting studies, harmonic distortion analysis (IEEE 519), arc flash hazard calculations (IEEE 1584), substation earthing grid design (IEEE 80), and underground cable ampacity sizing.
- Dynamic Models and Grid Integration: Developing PSSE and PSCAD User-Defined Models (UDM), transient stability simulation, critical clearing time (CCT) determination, small-signal stability analysis, sub-synchronous resonance (SSR/SSCI/SSTI), and full grid compliance verification against national grid codes (EETC, SEC, DEWA, SEWA).
- Electromagnetic Transients and Insulation: High-frequency transient simulation on PSCAD/EMTDC, Insulation Coordination Studies (ICS per IEC 60071), surge arrester selection and placement, capacitor bank switching transients, Neutral Grounding Reactor (NGR) sizing, Transient Recovery Voltage (TRV) verification on circuit breakers, and transformer inrush energization analysis.

Methodology & Project Delivery Workflow
Our engineering delivery aligns with MEPCO’s structured 6-stage project execution framework, ensuring quality throughout input verification, design modeling, and client handover:
- Stage 01 — Scope & Criteria Definition: Establish study boundaries, utility tie-in data, single-line diagrams, and client objectives.
- Stage 02 — Data Audit & Modeling Assumptions: Collect, verify, and validate manufacturer datasheets, impedance tolerances, and site operating configurations.
- Stage 03 — Simulation Model Development: Build detailed, validated mathematical digital models in specialized power software.
- Stage 04 — Computational Analysis & Verification: Execute base-case and contingency scenarios, conducting rigorous internal peer reviews.
- Stage 05 — Client Review & Approval: Present study findings, address technical comments, and participate in technical clarification sessions.
- Stage 06 — Final Handover: Deliver formal certified engineering reports, executive summaries, and native simulation model files.
