HDI Electrical Services delivers cutting-edge power system studies designed to enhance the reliability,
safety, and efficiency of modern electrical networks. Our team employs industry-leading software
such as PSS/E, DIgSILENT, and ETAP to provide utilities, industries, and renewable developers with
practical, data-driven solutions.
Why Power System Studies Matter
As grids evolve to accommodate more renewables, electrification, and automation, system studies
are essential for mitigating risks such as voltage instability, harmonics, overloads, and non-compliance.
Our services bridge the gap between engineering theory and operational performance—ensuring
regulatory compliance and network resilience.
Our Comprehensive Power System Studies Include:
- Load Flow & Fault Analysis
– Evaluate power flows, losses, and voltage profiles under steady-state and contingency
scenarios
– Identify bottlenecks, overloaded assets, and verify equipment fault ratings - Grid Connection & Renewable Integration Studies
– Assess grid code compliance for solar, wind, and BESS integration
– Conduct transient, dynamic, and stability studies for utility-scale projects - Voltage Quality & Harmonic Analysis
– Analyze flicker, voltage sags/swells, and power quality disturbances
– Design harmonic filters to eliminate distortion from VFDs, inverters, and EV chargers - Protection & Safety Studies
– Relay coordination studies to ensure precise fault isolation
– Arc flash hazard assessment with PPE recommendations
– Grounding system design per IEEE-80 safety standards - Advanced Stability Studies
– Frequency response and inertia analysis for low-inertia grids
