Grid Compliance Studies
Utility interconnection compliance — df/dt relays, islanding schemes and load-shedding schemes for renewable and conventional plants.
TAS delivers specialized power system studies, detailed design engineering and technical training for utilities, renewables and industrial facilities — combining modern simulation tools with strict international standards compliance.
What we do
From a single industrial system to highly complex, national grid–level networks — our studies, designs and audits are performed to IEC, IEEE, ANSI and GOST standards.
Utility interconnection compliance — df/dt relays, islanding schemes and load-shedding schemes for renewable and conventional plants.
Power-factor correction, equipment loading, voltage profiles and reactive power optimisation for steady-state network performance.
Fault-level analysis to IEC 60909, ANSI and GOST standards, including equipment short-time rating verification and breaker duty.
Angular stability, critical clearing time and voltage stability studies that keep your network secure through disturbances.
Switching and lightning overvoltage studies, ferroresonance analysis and arrester selection for substations and networks.
Over-current and earth-fault coordination and unit protection schemes to IEEE 242 — selective, sensitive and dependable.
Harmonic distortion analysis, filter design and resonance screening to IEEE 519 for clean, compliant power quality.
IEEE 1584 incident-energy analysis, arc-flash boundaries and equipment labelling that protect people and meet audit requirements.
Static and dynamic motor-starting studies — voltage dip, starting time and impact assessment for large MV motor fleets.
Substation earthing design, soil resistivity testing and lightning protection system design for safe, compliant installations.
Complete design packages — single-line diagrams, layouts and LV/MV design detailing in AutoCAD Electrical, ready for execution.
Independent review of protection philosophies, settings and coordination — an expert second opinion before energisation or audits.
Who we power
Deep domain experience across the industries where reliable power is non-negotiable.
Solar, wind and BESS plants — grid compliance, protection and performance studies at utility scale.
Mission-critical electrical infrastructure with redundancy, protection coordination and arc-flash safety built in.
Continuous-process plants — motor starting, power quality and protection that keep production lines running.
Utilities and grid operators — from substation studies to network analysis.
Study Capabilities
A clear view of the technical problem statements, simulation packages and compliance deliverables our engineers handle.
Comprehensive interconnection packages — steady-state load flow, P-Q capability, fault ride-through (LVRT/HVRT), frequency response and islanding protection schemes.
IEEE 1584 incident-energy calculations, arc flash boundary determination, trip-time optimization and NFPA 70E equipment labeling for worker safety and audit readiness.
Time-current characteristic (TCC) curve development, selective coordination for overcurrent, earth fault and differential protection to prevent nuisance tripping.
Mission-critical infrastructure studies covering N+1/2N redundancy verification, dynamic motor/chiller starting, transient voltage dips and harmonic screening.
Harmonic distortion analysis at the Point of Common Coupling (PCC), resonance frequency screening and passive/active filter design to meet IEEE 519 standards.
Soil resistivity modeling, touch and step potential calculations, ground grid conductor sizing and rolling-sphere lightning protection shielding to IEEE 80 & IEC 62305.
How we work
Network data, equipment parameters and operating scenarios are gathered and built into a calibrated simulation model.
Studies are executed in industry-standard tools — ETAP, PSCAD, PSS/E and DIgSILENT PowerFactory.
Results are benchmarked against IEC, IEEE, ANSI and utility-specific grid codes and standards.
Clear findings and actionable recommendations — settings, ratings and designs you can implement directly.
On-site commissioning support and engineer training so your team owns the result with confidence.
Knowledge transfer
Hands-on, tool-based courses for engineers and corporate teams — delivered at our Pune facility or your site.
