Job Description Summary
GE Grid Solutions has exciting opportunities in HVDC systems engineering function. The roles would comprise of execution of projects and could entail actions like - interpret the customer’s technical enquiry, design the most cost-effective overall solution for an HVDC installation utilizing the PES (power electronics solutions), aiming to minimising the total cost, and to specify the main (high-value) items of bought-out equipment for HVDC Projects. Successful candidates will also be involved in the development and industrialisation of tools and processes and will be required to have technical knowledge and experience in the field of power system engineering (academic and professional).
The candidates will be part of an established team of experienced power systems engineers which will provide them with various opportunities to develop their skills in the field of high voltage AC and DC power system design via mentoring by Systems Expert, on-the-job training, classroom training (such as the HVDC university training modules), cross-functional assignments etc.
Job Description
Essential responsibilities:
Candidates would be involved in either system design or systems studies and are expected to have experience in a number of these areas:
Systems Design:
Equipment Lifecycle Management
Manage the lifecycle of high economic value High Voltage equipment such as power transformers, instrument transformers, reactors, capacitors, and surge arresters, covering the development of its specification, validation and verification (testing) of design, witnessing test, support in installation and commissioning.
Insulation Coordination Studies
Determine the temporary and transient overvoltage stresses on HV equipment and provide the protective level requirements for the surge arresters.
Main Circuit Design
Develop an integrated scheme design that meets the Customer’s needs, by developing requirements on the ratings and functionalities of the different HVDC system’s subsystems, in an optimised and cost-effective manner.
Losses Management
Create, verify, and validate the electrical power losses models for HVDC systems and subsystems, providing insight to customers and leaders and managing the risks, issues and opportunities that affect the systems throughout their lifecycle.
Reliability, Availability and Maintainability Studies and Management
Create, verify, and validate the reliability, availability and maintainability models for HVDC systems and subsystems, providing insight to customers and leaders and managing the risks, issues and opportunities that affect the systems throughout their lifecycle.
Assessment of noise level at various locations of HVDC station and propose mitigation solutions if required.
Systems Studies:
Network Studies
Confirmation of the correct interaction between the equipment, its control system, and the rest of the network. Studies include Transient Stability studies, Load Flow Studies, Short Circuit Studies, Interaction Studies.
Transient Studies
Determination (by simulation) of temporary and transient overvoltage stresses on equipment and surge arrester energy ratings. Studies include Transient over voltage (TOV), Breaker Transient Recovery Voltage (TRV), Lightning Studies etc.
Harmonic Analysis and Power Quality
Conducting AC and DC harmonic performance and harmonic stability studies for HVDC converter stations for VSC and LCC HVDC schemes. Radio Frequency Interference studies and Electromagnetic Compatibility studies. Power Line Carrier Interference studies and filters. Design of AC, DC, and High Frequency harmonic filters and screening. Calculations of filter performance and rating. Creation of project-specific equipment specifications for filter reactors/capacitors/resistors.
