EHV, HV, and MV Power System Studies

Advanced Modeling, Reliable Results – Powered by PSCAD & PSS®E

At Risk Work Inc., we specialize in delivering high-fidelity power system studies for Extra High Voltage (EHV), High Voltage (HV), and Medium Voltage (MV) networks. Our engineering team utilizes industry-leading simulation tools – PSCAD and PSS®E – to evaluate, model, and ensure system integrity across utility-scale and industrial power systems.

⚡ Load Flow & Short Circuit Analysis

We model steady-state and dynamic operating conditions to evaluate bus voltages, line loadings, fault levels, and equipment ratings.

Compliance with IEEE/ANSI/IEC standards
Critical for design validation and relay coordination
System planning and equipment sizing

🌀 Transient Stability Analysis

Using PSS®E and PSCAD, we simulate system behavior during faults, switching events, and generator trips to ensure grid reliability.

Rotor angle and voltage stability
Islanding and re-synchronization studies
Black start planning

🔌 Protection Coordination Studies

We assess relay settings and coordination to protect transformers, lines, and busbars while minimizing system outages.

TCC curve analysis
Relay setting recommendations
Compliance with PRC-023 and PRC-025

⚠️ Induced Voltage Studies (PSCAD-Powered)

We perform detailed electromagnetic transient (EMT) studies to identify induced voltages from overhead lines to adjacent infrastructure (e.g., pipelines, fences, communication lines).

Critical for worker safety and public protection
Time-domain simulations using PSCAD
Ground potential rise (GPR) and touch/step voltage evaluations
Coordination with grounding and shielding design

🌩️ Switching Surge and Temporary Overvoltage Analysis

We simulate fast transients due to breaker operations or load rejection events.

Arrestor placement recommendations
Mitigation of insulation stress
Analysis of resonance and ferroresonance

🔄 Harmonics and Power Quality Studies

Harmonic distortion, flicker, and voltage sags can damage sensitive loads or violate utility interconnection requirements. Our studies identify and mitigate these risks.

IEEE 519 compliance
Harmonic filter design
Nonlinear load analysis

⚙️ Contingency and N-1 Analysis

We assess system behavior under failure of one or more components to ensure your grid withstands real-world operational challenges.

Transmission planning compliance
Critical for ISO/RTO interconnection studies
System resilience assessments
IEEE 519 compliance
Harmonic filter design
Nonlinear load analysis
