HVDC (High Voltage Direct Current) is a product group in Hitachi Energy, which develops, manufactures and sells DC transmission systems on a global market. HVDC technology is used to transmit electricity over long distances and for power transmission via submarine cables. It is also used to connect power systems.
Interested in a technically stimulating job combining high voltage and frequencies, where it is required to master both state-of-the-art harmonic and filter design calculations as well as the challenges of working in large scale projects, all in a highly international environment? Then maybe you should consider becoming part of our team at the harmonic analysis group at HVDC!
Your responsibilities
Participate and collaborate in project groups, responsible for electrical system design of HVDC converter stations. Be responsible for harmonic related studies <15 kHz and compliance measurements during commissioning.
Evaluate whether specified harmonic power quality requirements can be fulfilled; and analyze small-signal stability in the harmonic range (harmonic stability); when connecting HVDC station to the network or windfarm. If necessary, propose active or passive mitigation measures such as harmonic filters or harmonic dampers.
Calculate harmonic stresses in all HVDC station main circuit equipment’s and evaluate whether mitigation measures or re-designs are required due to excessive harmonic stresses.
Develop small tools in e.g., Excel, MATLAB or Python to effectively analyze and process large amount of data for your study work.
Effectively participate in negotiations, internally and with customers or suppliers. Where you can present your work and discuss challenges and path forward on a higher level.
