SEN EDS provides advanced PSCAD software and consulting services for the simulation and analysis of power systems in Assam. Our expertise helps design, optimize, and troubleshoot complex electrical networks, ensuring safe and reliable operations.
Load Flow Study
- Load flow studies analyze the flow of electric power, current, voltage, real power, and reactive power under various load conditions.
- These studies ensure system voltages and currents remain within safe limits during the design phase of new projects or when modifying existing systems.
- SEN EDS conducts detailed load flow assessments to enhance the performance and reliability of power systems in Assam.
Short Circuit Study
- A short circuit study examines the magnitude of currents during electrical faults and evaluates them against the ratings of installed equipment and protection devices.
- Our in-depth analysis ensures the proper functioning and safety of power systems by addressing operational validation and new design requirements.
Dynamic Study
- Dynamic and stability studies assess scenarios such as transient faults, critical clearing times, load acceptance and rejection, and dynamic motor starting.
- SEN EDS focuses on ensuring the stability and resilience of synchronous machines under various operating conditions.
Sub-Synchronous Resonance (SSR)
- SSR involves the interaction between series capacitors and mechanical/torsional masses in generators at sub-synchronous frequencies.
- Using Eigenvalue analysis and passive frequency scan methods, SEN EDS evaluates and mitigates SSR risks in conventional synchronous machines and long turbine shaft systems.
Power Quality Analysis
- Power quality analysis assesses the safety and efficiency of a facility’s power supply.
- SEN EDS ensures optimal system performance by identifying and addressing power quality issues in industrial and commercial setups.
Harmonic Analysis
- Harmonic analysis investigates non-sinusoidal waveforms caused by periodic distortions in voltage and current.
- SEN EDS uses advanced digital simulations to determine harmonic distortion levels and implement filtering solutions for maintaining system stability in Assam.
Flicker Analysis
- Flicker analysis evaluates voltage changes and flicker intensity caused by load variations or renewable energy sources like wind power plants.
- SEN EDS ensures compliance with flicker standards to maintain power quality across connected networks.
Sub-Synchronous Control Interaction (SSCI)
- SSCI involves stability issues caused by interactions between wind turbine control systems and series-compensated networks.
- Our solutions address varied operating conditions to suppress SSCI and protect wind turbines and electrical systems in Assam.
Insulation Coordination Study
- Insulation coordination identifies surge arrester requirements and limits overvoltage to protect power systems from electrical stresses.
- SEN EDS conducts precise insulation coordination studies to safeguard electrical networks from increased currents and voltages.
Lightning Overvoltage Study
- Lightning overvoltages are fast-front transient voltages caused by lightning strikes on overhead lines.
- SEN EDS analyzes 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 fault tripping, reclosing, or regular operations of switching devices.
- We mitigate the effects of switching transients in transmission and distribution systems to enhance reliability.
Temporary Overvoltage (TOV) Study
- TOVs are long-duration power-frequency overvoltages caused by load rejection, resonance, or transformer energization.
- SEN EDS evaluates circuit breaker performance, including transient recovery voltage (TRV) and rate of rise of recovery voltage (RRRV), to ensure system safety under fault conditions.
TRV Analysis
- Transient Recovery Voltage (TRV) analysis examines voltage differences across breaker terminals post-current interruption.
- SEN EDS ensures optimal breaker performance by addressing high-frequency oscillations and recovery voltage stability.
- VFTOs contain high-frequency components that can overstress transformer insulation, especially in GIS designs.
- SEN EDS mitigates VFTO impacts caused by switching operations, particularly from disconnector switches, ensuring reliable system design and operation.
