Modelling in practice
In 2024, EES had a customer report a fault with an excitation system. Our engineers took measurements onsite and built a model of the system when they realised the excitation supply current readings were peaking abnormally. After running many experiments in MatLab SimuLink, they produced readings that matched up to the measurements taken and identified a periodic fault.
The customer shared the trace imaging with the equipment manufacturer. The manufacturer instructed them to examine a specific part of the system, where engineers found several burnt-out components. The customer was then able to replace these components and rectify its issue.
Power system modelling is an essential service in power generation engineering. The rarity of companies that offer on-site investigation, laboratory modelling and fault diagnosis in one package represents an area for the industry to grow. Companies such as EES have the technical capability and the decades of expertise to prevent extensive, expensive downtime and allow engineers to get back to being bold.
