Auxiliary Power System Design Engineer

Overview

Job Description Summary The North and South Europe Grid System Integration (GSI) team delivers a wide range of high voltage AC and DC transmission projects, including the connection of large Offshore Windfarms, and is looking for an “Auxiliary Power System Design Engineer” to join the team. These large and complex projects involve the installation of a significant amount of equipment and require the design of a supporting auxiliary power network that is both efficient and resilient to ensure the overall system has the required availability.

In this role and working with the other members of the design team, you will first develop the system requirements, and then the auxiliary power network architecture, before going on to specify the equipment and other components needed for its realisation and finally managing the design integration. The system we design, validate and manage includes equipment such as:
Auxiliary Transformers, Medium & Low voltage switch gear, Diesel Generator Systems, Batteries, UPS and cables.

Grid Solutions, a GE Renewable Energy business, serves customers globally with over 13,000 employees. We provide power utilities and industries worldwide with equipment, systems and services to bring power reliably and efficiently from the point of generation to end power consumers. Grid Solutions is focused on addressing the challenges of the energy transition by enabling the safe and reliable connection of renewable and distributed energy resources to the grid.

We electrify the world with advanced grid technologies and accelerate the energy transition.

• Lead the design of the auxiliary power supply network (Up to 11kV) on all projects undertaken and ensure that the system efficiently meets the needs of the project.
• Understand the customers’ requirements, regulatory constraints and standards that need to be adhered to and ensure that they are fully considered by all stakeholders.
• Develop a provisional load list and auxiliary power system architecture that meets the needs of the project.
• Model the proposed system on a suitable software platform, such as Amtech Prodesign / Caneco BT, to ensure the correct system performance, and for the purpose of equipment sizing and specification.
• Ensure that the network is correctly protected and coordinated.
• Present the engineering options to internal stake holders and customers in order to gain agreement and progress to the next design stage.
• Create the necessary documents and reports to articulate the proposed design and its benefits to the Customer.
• Create equipment procurement specifications in order to engage the supply chain and obtain vendor offers for the required equipment. Working with the Sourcing team review the offers and determine the best technical solution.
• Develop the proposal into a practical solution and supervise the creation of the design and installation integration drawings and other documents.
• Work with the mechanical, electrical and civil designers to integrate the auxiliary system design into the overall solution and ensure that the necessary provision is made and interfaces are managed.
• Engage with the Customer, as required, to articulate the proposed design and answer questions or queries that may be raised.
• Working with the installation and commissioning team, develop a testing regime to ensure that the system meets its functional and legislative obligations.

• A first degree in electrical engineering. (Or equivalent experience)
• More than 5 years’ experience working in a role where you are the design and delivery of auxiliary power supply networks up to 11kV, and have a strong working knowledge of the following topics:
• Auxiliary Power Systems in Transmission and Distribution Substations, HVDC Converter Stations (Onshore and Offshore)
• Electrical Load Flow and Equipment Sizing (such as Auxiliary Transformer and Automatic Voltage Regulators)
• LV/MV Protection Design
• LV/MV AC Distribution Equipment
• LV/MV Cabling
• DC Battery Systems
• Diesel Generators
• UPS
• Earthing and Bonding Practices in Substations
• DNO supply coordination and connection works design
• Be a competent user of a LV/MV network modelling software…
