Job description

HVDC Project Engineer – Harmonic Analysis

The HVDC (High Voltage Direct Current) product group within Hitachi Energy develops, manufactures, and sells DC transmission systems on a global market. HVDC technology is used to transmit electricity over long distances and to connect offshore wind farms to the grid. We are looking for two project engineers to join the Harmonic Analysis team. We encourage applications even if you do not meet every requirement.

In this role you will work with harmonic analysis, power quality, and electrical system studies for HVDC converter stations. You will collaborate across projects and contribute to the successful integration of HVDC stations with electrical networks and offshore wind farms.

Key Responsibilities

• Collaborate in project teams responsible for the electrical system design of HVDC converter stations.
• Perform harmonic studies below 15 kHz and support compliance measurements during commissioning.
• Evaluate whether specified harmonic power quality requirements can be fulfilled.
• Analyze small‑signal stability in the harmonic range when connecting an HVDC station to a network or wind farm.
• Propose active or passive mitigation measures, such as harmonic filters or harmonic dampers, when needed.
• Calculate harmonic stresses in HVDC station main circuit equipment and assess whether mitigation measures or redesigns are required.
• Develop tools in Excel, MATLAB, or Python to efficiently analyze and process large amounts of data.
• Participate in technical discussions and negotiations with colleagues, customers, and suppliers.
• Present your work and contribute to discussions on challenges and the path forward.
• Write clear and professional technical reports describing complex study work and results.
• Participate in conferences and standardization work groups within the international engineering community.

Required Qualifications

• Bachelor’s or Master’s degree in Electrical Engineering, Electronic Engineering, or Engineering Physics.
• General understanding of electrical power systems and related equipment.
• Ability to model and analyze electrical circuits in the frequency domain, both by hand and using computer‑based tools.
• Understanding of how multi‑phase systems can be analyzed using modes.
• Practical approach to problem solving; willingness to challenge inputs and discuss solutions with customers.
• Strong communication and technical report writing skills.
• Programming experience in MATLAB is highly beneficial; experience with Python is also valued.
• Experience with EMT tools such as PSCAD is advantageous.
• Fluency in written and spoken English.
