Tallinn University of Technology, School of Engineering, Department of Electrical Power Engineering and Mechatronics offers a 4-year PhD position in Power Engineering and Mechatronics.
Proposed doctoral thesis topic: "Power system substation asset monitoring and condition analysis in future power systems"

Supervisors: Professor Jako Kilter and Mart Landsberg (Elering AS)

Abstract
Objective of this research is to assess the applicability of different measurements to enable reliable and usable asset management approaches considering the actual substation asset condition, and analyse the asset management approaches and develop methodology to include actual asset condition and its ranking to asset management process.

Description

Power system asset management in current systems is mostly related to interval-based approach and the actual condition of the asset is not observed nor relevant. This approach in future power system is seen as obsolete as the finances available should be used as much as possible in an appropriate manner.

Therefore, this research has two main objectives:

  • Understand current and alternative approaches for substation asset condition monitoring and determine the main influencing factors to increase the observability of asset condition. These include collecting, assessing and making decisions on available assets conditions using the available measurement data but also considering applicability of new sensors technology, IoT and cyber security. Various sensitivities and alternatives shall be determined and as much as possible highlighted considering the limitations in actual power systems.
  • Implement probabilistic and risk management theory or some other approach to enable condition based asset management approach in power system. There are various type of information available from substations and the descisions made shall be based on these. Usually these include measurments from SCADA, WAMS, environment measurements, etc. In addition, the objective is to develop methodolgy (including substation based asset condition and component/asset ranking) which combines the available information, assesses the level and content of this data and determine the level and extent of data what is necessary to enable the approach of condition based asset management.

All these aspects shall enable secure, reliable and cost-effective asset life monitoring and management in future power systems including recommendations for appropriate system design enabling the most optimal techno-economical solution for substations. One of the objectives is also to develop comprehensive descision making principles and condition indexes that can be applicable in actual substation maintenance planning.
