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 Andhra Pradesh.
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 Andhra Pradesh.
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 Andhra Pradesh.
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.
