SEN EDS provides comprehensive consulting services utilizing EMTP® software for the simulation and analysis of complex power systems in Andhra Pradesh. Our expertise ensures precise studies for improved efficiency, reliability, and safety of electrical networks.
Insulation Coordination Study
- Electrical power systems are nonlinear and dynamic, often subjected to varying stresses from increased currents and voltages.
- Insulation coordination determines proper surge arrester selection and overvoltage limitations for system protection.
Lightning Overvoltage Study
- Lightning-induced overvoltages are fast-front transient voltages caused by lightning strikes on overhead lines.
- SEN EDS analyzes overvoltage, resonance, secondary arc current, 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 routine operations.
- We mitigate transient recovery voltages and transient currents associated with switching devices in transmission and distribution systems.
TRV Analysis (Transient Recovery Voltage)
- TRV refers to the voltage difference across breaker terminals after current interruption.
- SEN EDS examines high-frequency oscillations and power frequency stability to optimize breaker performance.
Very Fast Transient Voltage Analysis
- TRV refers to the voltage difference across breaker terminals after current interruption.
- SEN EDS examines high-frequency oscillations and power frequency stability to optimize breaker performance.
Harmonic Analysis
- Harmonic analysis investigates waveform distortions caused by non-sinusoidal currents or voltages.
- Using advanced simulations, we assess harmonic distortion levels and implement filtering solutions to ensure system stability.
Sub-Synchronous Control Interaction (SSCI)
- SSCI occurs due to interactions between wind turbine control systems and series-compensated networks.
- SEN EDS provides solutions to suppress SSCI under diverse operating conditions, protecting wind turbines and networks.
Transient Stability Study
- Transient stability involves analyzing power systems post-disturbances, focusing on synchronous alternators’ rotor dynamics.
- We compute critical clearing times and assess system voltage, frequency, and power flow under transient conditions.
Low Voltage Ride Through (LVRT)
- LVRT capability ensures generators remain connected during short voltage drops caused by grid faults.
- Our analysis ensures generators manage power imbalances effectively, maintaining system stability during LVRT events.
SEN EDS leverages advanced EMTP® software and a deep understanding of power systems to provide accurate analyses and tailored solutions. Partner with us to optimize the performance and reliability of Andhra Pradesh’s electrical networks.
