SEN EDS offers expert consulting services using EMTP® software to simulate and analyze complex power systems in Tamil Nadu. Our solutions ensure enhanced efficiency, reliability, and safety for electrical networks across the state.
Insulation Coordination Study
- Electrical power systems are highly dynamic and often face stresses from increased currents and voltages.
- Insulation coordination helps in selecting appropriate surge arresters and limiting overvoltage for optimal system protection.
Lightning Overvoltage Study
- Lightning overvoltages are fast-front transient voltages caused by lightning strikes on overhead lines.
- SEN EDS performs in-depth analysis of overvoltage, resonance, secondary arc currents, and line protection stability for up to 400kV OHL circuits under various network conditions.
Switching Overvoltage Study
- Switching overvoltages occur during electromagnetic transitions caused by fault tripping, reclosing, or standard operations.
- We analyze and mitigate transient recovery voltages and currents from switching devices in transmission and distribution systems.
TRV Analysis (Transient Recovery Voltage)
- TRV represents the voltage difference across breaker terminals immediately after current interruption.
- Our studies focus on high-frequency oscillations and power frequency stability to optimize breaker performance and reliability.
Very Fast Transient Voltage Analysis
- VFTOs, with high-frequency components, can overstress transformer insulation and are critical in GIS design.
- SEN EDS mitigates VFTO impacts, particularly those from disconnector switch operations, ensuring safe and efficient system operations.
Harmonic Analysis
- Harmonic analysis identifies waveform distortions caused by non-sinusoidal currents or voltages.
- Using advanced simulations, we determine harmonic distortion levels, implement filtering solutions, and maintain system stability.
Sub-Synchronous Control Interaction (SSCI)
- SSCI arises from interactions between wind turbine control systems and series-compensated networks.
- We deliver robust solutions to suppress SSCI, protecting wind turbines and electrical networks under varying conditions.
Transient Stability Study
- Transient stability focuses on power systems after disturbances, analyzing synchronous alternator rotor dynamics.
- Our studies compute critical clearing times and assess voltage, frequency, and power flow under transient conditions.
Low Voltage Ride Through (LVRT)
- LVRT capability ensures generators stay connected during brief voltage drops caused by grid faults.
- Our analysis enables effective power balance management, ensuring system stability during LVRT events.
SEN EDS combines advanced EMTP® software and expert knowledge to deliver precise analysis and tailored solutions. Partner with us to enhance the reliability, efficiency, and performance of Tamil Nadu’s electrical networks.
