This article presents lifetime estimation using robust control based on thermal path degradation condition of insulated-gate bipolar transistor wind power modules. Online measurements of the on-state voltage [Formula: see text] are considered to be a promising method for obtaining a thermal-sensitive electrical parameter for wire-bond lift-off. This parameter demonstrates a good correlation with junction temperature. Due to the harsh environment, disturbances and uncertain parameters are founded within the compact set of wind energy generation systems. The uncertainty sacrifices some degree of accuracy of junction temperature measurements. Hence, robust control theory has been utilized to synthesize [Formula: see text] controller for the thermal impedance of high-power insulated-gate bipolar transistors. To study this reliability problem, an integrated model of wind energy generation system is built in MATLAB/Simulink for the closed-loop system. Simulation results show the benefit of the designed controller compared to the open-loop system in terms of thermal cycles of junction temperature and lifetime estimation.

In the exploration of new energy sources and the search for a path to sustainable development the reliable operation of wind turbines is of great importance to the stability of power systems. To ensure the stable and reliable operation of the Insulated Gate Bipolar Transistor (IGBT) power module, in this work the influence of changes with aging of different electro-thermal parameters on the junction temperature and the case temperature was studied. Firstly, power thermal cycling tests were performed on the IGBT power module, and the I-V characteristic curve, switching loss and transient thermal impedance are recorded every 1000 power cycles, and then the electrical parameters (saturation voltage drop and switching loss) and the thermal parameters (junction-to-case thermal resistance) of the IGBT are obtained under different aging states. The obtained electro-thermal parameters are substituted into the established electro-thermal coupling model to obtain the junction temperature and the case temperature under different aging states. The degrees of influence of these electro-thermal parameters on the junction temperature and case temperature under different aging states are analyzed by the single variable method. The results show that the changes of the electro-thermal parameters under different aging states affects the junction temperature and the case temperature as follows: (1) Compared with other parameters, the transient thermal impedance has the greatest influence on the junction temperature, which is 60.1%. (2) Compared with other parameters, the switching loss has the greatest influence on the case temperature, which is 79.8%. The result provides a novel method for the junction temperature calculation model and lays a foundation for evaluating the aging state by using the case temperature, which has important theoretical and practical significance for the stable operation of power electronic systems.

AbstractThe paper analyses the role of control and monitoring of electro-energetic equipment in order to reduce operational costs, increase profits and reduce carbon emissions. The role of SCADA and EcoStruxure Power systems is presented and analysed taking into account the energy consumption and its savings. The paper presents practical and modern solutions to reduce energy consumption by up to 53%, mass by up to 47% and increase the life of the equipment by adjusting the electrical parameters. The Integrated Navigation System has allowed an automatic control and an efficient management. For ships, the implementation of an energy efficiency design index and new technologies was required for the GREEN SHIP project.
