Design interfaces with existing infrastructure while ensuring minimal disruption. 4. Secondary Engineering: - Protection Systems: Design comprehensive protection schemes, including differential, distance, overcurrent, and earth fault protection, ensuring fast and reliable fault detection and isolation. - Control Systems: Design control logic and schemes for automation, including the operation of circuit breakers, isolators, and other switchgear. Ensure seamless integration with remote operation systems and SCADA. - Metering & Instrumentation: Specify and design the metering and instrumentation systems required for accurate monitoring and billing. Include current and voltage transformers, energy meters, and transducers. 5. Equipment Sizing & Selection: - Transformer Sizing: Calculate and select appropriate transformer ratings, considering factors such as load growth, fault levels, efficiency, and cooling requirements. - Switchgear Sizing: Determine the correct ratings for circuit breakers, switchgear, and other protective devices, ensuring they can safely interrupt fault currents without compromising system integrity. - Capacitor Bank & Reactor Design: Design and size capacitor banks for reactive power compensation and reactors for controlling over-voltages or for current limiting in the substation. 6. Integration with Renewable Energy Systems: - Grid-Tie Design: Design interfaces for the connection of utility-scale renewable energy systems (e.g., solar, wind) to the transmission grid, considering voltage levels, harmonics, and stability. - Inverter & Converter Coordination: Ensure proper coordination between EHV equipment and inverters or converters used in renewable energy systems. Address issues such as power factor correction, harmonics filtering, and synchronization. 7. Owners Engineering: - Technical Advisor: Act as the technical advisor to the project owner, providing expert guidance on all aspects of EHV substation and transmission line design, construction, and commissioning. - Design Validation: Review and approve design documents, drawings, and calculations provided by contractors or third-party consultants to ensure compliance with project specifications, industry standards, and best practices. 8. Equipment Design Review: - Technical Evaluation: Conduct a thorough technical evaluation of vendor proposals, including equipment specifications, performance data, and compliance with project requirements. Ensure that the selected vendors have a proven track record of delivering high-quality EHV equipment. - Specification Compliance: Review and validate equipment designs provided by vendors/OEMs to ensure they comply with the projects technical specifications, industry standards, and regulatory requirements. - Design Validation: Perform detailed design validations, including reviewing engineering drawings, schematics, and technical data sheets. Ensure that the equipment is appropriately designed for the specific operating conditions and load requirements of the project. - Material and Component Verification: Verify the materials and components specified by the vendor, ensuring they meet the required durability, reliability, and performance standards. Assess the suitability of materials for the specific environmental and operational conditions of the project site. 9. Compliance and Standards Adherence: - Industry Standards: Ensure that all designs comply with international and national standards such as IS, IEC, NEC, IEEE, ANSI, and regional grid codes. 10. Innovative Design Solutions: - Advanced Technologies: Stay abreast of emerging technologies in EHV systems, such as digital substations, gas-insulated switchgear (GIS), and advanced protection relays, and incorporate them into designs where applicable. - Cost Optimization: Develop designs that balance cost-efficiency with performance, exploring options such as modular construction, prefabricated substations, and standardized components. 11. Quality Assurance: - Design Reviews: Conduct rigorous design reviews and cross-discipline checks to identify and rectify any potential issues early in the design process. - Documentation: Prepare and maintain comprehensive design documentation, including technical reports, design calculations, and as-built drawings. 12. Coordination with Civil and Structural Design: - Foundation Design: Collaborate with civil engineers to design appropriate foundations for high-voltage equipment, considering factors such as weight, vibrations, and seismic conditions. - Structural Integration: Ensure that the structural design supports the electrical design, providing adequate clearances, accessibility, and safety measures. Selection process: Telephonic discussion: Preliminary round of discussion over a call by the company HR. Technical round: Technical round of discussion with the domain specialist in Pune/ Vadodara office, MS Teams may be preferred for outstation candidates. Director meeting: At Pune office before conclusion.
