Generator Circuit Breakers (GCB) play a major role in power plant protection, offer more flexibility for plant operation and enable the implementation of efficient solutions to reduce investment cost. Maintenance, energy efficiency and carbon footprint are now also enhanced thanks to GCB architecture optimization. Objective of the internship is to carry out arc and thermal-fluid-dynamic simulations to evaluate the performances of a Generator Circuit Breaker (GCB) during operation under steady state and transient electrical loads. One of the objectives is to verify the thermal limits of the device according to the GCB standards and customer requirements. The study will be carried out with the software FLUENT (thermo-fluid dynamics), with an ABB in-house toolbox for Electro-Thermal Analysis based on the Full Maxwell module for the electromagnetic losses and with a dedicated tool for the arc simulations. The candidate will receive dedicated assistance and support from the HAPG engineers and scientists. Therefore, we are searching for an outstanding personality who will support our team in Zurich. The duration of the internship is 6 to 12 months.
