Cable Sizing
Selection and verification of MV and LV power conductors based on continuous ampacity, voltage drop, and short-circuit thermal limits.
User Defined Model Development
Development of advanced user-defined dynamic models (UDM) for conventional and renewable power plants in PSSE and PSCAD/EMTDC.
Dynamic Stability
Evaluation of transient stability, rotor angle stability, voltage recovery, and frequency response under transmission system disturbances.
Grid Compliance
Verification of power plant interconnection compliance with utility transmission codes (SEC, EETC, DEWA, etc.).
Dynamic Model Acceptance Tests (DMAT)
Rigorous model acceptance testing verifying model accuracy against transmission system operator requirements.
Small Signal Stability
Eigenvalue analysis, modal damping calculation, and power system stabilizer (PSS) tuning around steady-state operating points.
Sub Synchronous Interactions (SSR, SSCI, SSTI)
Evaluation of Sub-Synchronous Resonance, Controller Interaction, and Torsional Interaction for series-compensated lines and renewables.
Insulation Coordination (ICS)
Selection of surge arresters, temporary, switching, lightning, and very fast transient overvoltage (VFTO) evaluation per IEC 60071.
Capacitor Bank Switching
Transient inrush currents, outrush currents, overvoltages, and damping reactor sizing during capacitor bank energization.
Neutral Ground Reactor (NGR) Sizing
Determination of neutral grounding reactor parameters for specific substation earthing arrangements and fault limitation.
