Case Study: Evaluating Next-Gen HVDC Conductor Designs for Electromagnetic Suitability

Currents & Connections 

High-voltage direct current (HVDC) conductor designs play a pivotal role in the efficiency and reliability of power transmission infrastructure. The evaluation of these designs for electromagnetic suitability is a complex and critical task that demands precise modeling, extensive computational resources, and meticulous data integration. The success of such evaluations directly impacts the operational efficiency, safety, and regulatory compliance of HVDC systems. This case study explores how Team Manav successfully addressed the challenges in evaluating next-generation HVDC conductor designs under a tight deadline.

Problem Statement

APAR and Sterlite, leaders in the power transmission sector, faced the daunting task of evaluating new HVDC conductor designs within a significantly reduced timeframe of 15 days, a process that typically requires 40 days. The challenges included:

Inaccurate Electromagnetic Modeling

Risks of inaccurate simulations due to complex geometry and material properties.

Inadequate Computational Resources

Potential oversimplification of models due to limited high-performance computing access.

Data Integration Errors

Risk of errors from improper integration of new data or design changes.

Non-Compliance with Standards

Potential legal and safety risks from non-compliant designs.

Underestimated Risk Assessment

Threats to infrastructure safety from incomplete risk assessments.

Cost Overruns

Potential delays and rework costs from inaccurate analyses.

Safety Hazards

Risks to personnel and infrastructure from unidentified design flaws.

Approach

To overcome these challenges, Team Manav employed following multi-faceted approach:

Precision in Electromagnetic Modeling

Utilizing advanced computational electromagnetics, Manav developed a sophisticated simulation engine combining numerical techniques with multi-physics coupling to ensure accurate results.

Collaborative Simulation

Implementing a cloud-based collaboration platform, the team facilitated secure, transparent data sharing and model refinement. This platform leveraged high-performance computing for faster, more accurate analyses.

Optimizing Designs

The use of an autonomous design exploration framework allowed the team to expedite the design process. Optimization algorithms quickly identified the best solutions while meeting stringent electromagnetic requirements, significantly reducing design cycle time.

Managing Risks

The creation of highly detailed digital representations of HVDC infrastructure, coupled with real-time data and risk models, enabled the prediction and mitigation of potential issues, ensuring system safety and reliability.

Environmentally Friendly Computing

Committed to sustainability, Manav developed an optical computing architecture for electromagnetic simulations, reducing their carbon footprint while maintaining powerful computing capabilities.

Benefits

The benefits of HVDC evaluation are profound. HVDC systems offer higher efficiency over long distances due to reduced power losses compared to alternating current (AC) systems. They provide improved stability and control over power flows, enabling better integration of renewable energy sources. HVDC transmission can also reduce the overall footprint of power lines, lowering environmental impact. Thorough HVDC evaluations ensure these benefits are fully realized, optimizing performance and reliability while meeting stringent regulatory and safety standards.

Conclusion

Team Manav’s innovative approach to evaluating next-gen HVDC conductor designs under stringent deadlines not only met the project’s requirements but also set new standards for excellence and reliability in power transmission infrastructure. This success demonstrates the critical importance of precision, collaboration, and advanced technology in overcoming engineering challenge
