Senior Manager EHV Design

The principal responsibilities essentially include:

Design and Engineering:

System Design & Configuration:

System Studies:

circuit analysis, voltage drop calculations, reactive power compensation, and

harmonic analysis to ensure the stability and reliability of the power system.

Configuration Layout:

including the arrangement of transformers, busbars, circuit breakers, isolators,

and other critical high-voltage components.

Redundancy & Reliability:

mechanisms in the design to enhance system reliability and minimize the risk of

outages.

Detailed Electrical Design:

clearly define the electrical connections and arrangements of all major equipment

in the substation.

Equipment Specification:

equipment, including transformers, switchgear, reactors, and capacitors, ensuring

compliance with project requirements and standards.

Cable Sizing & Routing:

current-carrying capacity, voltage drop, and thermal constraints. Design efficient

cable routing plans that minimize interference and optimize installation.

Earthing & Bonding:

substation, ensuring personnel safety, equipment protection, and compliance with

local regulations.

Primary Engineering:

High-Voltage Equipment Design:

voltage equipment such as power transformers, circuit breakers, disconnect

switches, current and voltage transformers, and surge arresters.

Busbar Design:

performance, electrical stress, and mechanical stability. Ensure appropriate

spacing, support, and insulation to prevent flashovers or mechanical failure.

Interconnection Schemes:

multiple substations or tie-lines into the existing power grid. Design interfaces with

existing infrastructure while ensuring minimal disruption.

Secondary Engineering:

Protection Systems:

differential, distance, overcurrent, and earth fault protection, ensuring fast and

reliable fault detection and isolation.

Control Systems:

operation of circuit breakers, isolators, and other switchgear. Ensure seamless

integration with remote operation systems and SCADA.

Metering & Instrumentation:

instrumentation systems required for accurate monitoring and billing. Include

current and voltage transformers, energy meters, and transducers.

Equipment Sizing & Selection:

Transformer Sizing:

considering factors such as load growth, fault levels, efficiency, and cooling

requirements.

Switchgear Sizing:

and other protective devices, ensuring they can safely interrupt fault currents

without compromising system integrity.

Capacitor Bank & Reactor Design:

power compensation and reactors for controlling over-voltages or for current

limiting in the substation.

Integration with Renewable Energy Systems:

Grid-Tie Design:

energy systems (e.g., solar, wind) to the transmission grid, considering voltage

levels, harmonics, and stability.

Inverter & Converter Coordination:

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:

expert guidance on all aspects of EHV substation and transmission line design,

construction, and commissioning.

Design Validation:

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:

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:

vendors/OEMs to ensure they comply with the project’s technical specifications,

industry standards, and regulatory requirements.

Design Validation:

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:

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.

Compliance and Standards Adherence:

Industry Standards:

national standards such as IS, IEC, NEC, IEEE, ANSI, and regional grid codes.

Innovative Design Solutions:

Advanced Technologies:

systems, such as digital substations, gas-insulated switchgear (GIS), and

advanced protection relays, and incorporate them into designs where applicable.

Cost Optimization:

performance, exploring options such as modular construction, prefabricated

substations, and standardized components.

Quality Assurance:

Design Reviews:

to identify and rectify any potential issues early in the design process.

Documentation:

including technical reports, design calculations, and as-built drawings.

Coordination with Civil and Structural Design:
