High-fidelity power system analysis and engineering design for grid-scale infrastructure. From earthing studies to arc flash analysis — IEC and IEEE compliant.
Behind every reliable electrical network lies a deep understanding of its hidden complexities — non-linear behaviours, dynamic machine responses, and the delicate interplay between voltage, load, and stability. At GridPOC, we don't just run studies; we listen to your system's unique story. Whether you are planning a new generation facility, expanding a transmission corridor, or modernising an industrial distribution network, our power experts bring world-class proficiency in both RMS and EMT analyses. Using state-of-the-art tools and a human-centred approach, we translate technical intricacy into clear, cost-effective strategies — partnering with you from concept through commissioning. The result? A power system that is not only stable and compliant but also resilient, sustainable, and truly fit for the future.
We solve the power flow equations under N and N-1 contingency conditions — bus voltage magnitudes and angles, real and reactive power injections, transformer tap positions, and system losses. The result is a complete picture of steady-state behaviour, thermal limits, and operational headroom.
We calculate fault currents for all fault types — three-phase, single line-to-ground, line-to-line, and double line-to-ground. Equipment duty is verified for circuit breakers, cables, busbars, current transformers, switchgear, and earthing conductors. The result is a complete assessment of what your equipment can withstand — and what it cannot.
We evaluate harmonic distortion and resonance within the network to identify power quality issues that may impact performance or equipment life. Where required, we recommend practical mitigation measures for cleaner and more stable operation.
We assess IBR response during voltage disturbances at the POC — reactive current injection during the event, active power recovery after clearance, and connection status throughout and after the disturbance. The objective is generation that rides through, supports, recovers, and stays connected.
We simulate transformer disconnection and energisation to assess POC impact — voltage deviations, frequency response, and stability following the event. The objective is to identify risks before reliability or grid compliance is compromised.
We coordinate relays, breakers, and protective devices to ensure faults are cleared quickly and selectively. The result is a protection system designed to minimise disruption, reduce equipment stress, and improve overall system reliability.
Surge arrester selection, Basic Insulation Level (BIL) verification, and protective margin assessment for transformers, switchgear, and cables against lightning and switching overvoltages.
Incident energy calculations at all equipment panels, arc flash boundary determination, PPE category labelling, and working distance assessment per NFPA 70E and IEEE 1584.
An earthing system is the silent guardian of every electrical installation. You cannot see it, but when a fault occurs, it is the only thing standing between a minor trip and a catastrophic failure — between a worker walking away and a life lost. At GridPOC Power Systems, we treat earthing design and earthing study as two sides of the same critical coin. Using CDEGS and ETAP, we perform soil resistivity analysis, step and touch voltage calculations, fault current distribution modelling, and ground potential rise (GPR) evaluation — all benchmarked to IEEE 80, IEC 60364, or IS 3043. The result is not just a compliant report — it is an earthing system you will never have to think about, because we have already thought of everything.
CAD-integrated grounding grid design for substations, solar plants, and industrial facilities. Conductor sizing, buried depth, and spacing — each element optimised not for convenience, but for fault current dissipation. The earth takes what we give it. We make sure it does so safely.
IEEE Std 80Soil resistivity measured, not assumed. Wenner four-pin method. Two-layer soil modelling. Ground Potential Rise (GPR) calculated with precision. Because safety under fault conditions is not a feature — it is a promise.
IEEE 80 / IEC 60364A solar plant is more than panels and inverters — it is a living system whose real-world yield depends on geometry, shading, temperature, degradation, and grid interaction. At GridPOC Power Systems, we transform this complexity into bankable, buildable designs. Using PVsyst as our core analytical engine, we perform detailed energy yield forecasts, loss analysis, and array optimisation tailored to your site's unique solar resource and topography. From rooftop residential arrays to utility-scale PV farms, our engineering team delivers complete DC and AC side designs — module layout, string sizing, inverter selection, cable routing, and protection coordination. We don't just simulate; we listen to your project constraints, budget, and operational goals, then return a design that balances performance with practicality. The result? A solar plant that performs as predicted, integrates smoothly with the grid, and delivers sustainable returns over decades.
Large-scale PV plant geometry optimisation — row spacing, DC cabling routes, inverter placement, and yield-maximising tilt angle analysis for utility-scale solar farms.
