Speech Title:Synergistic Deterioration Mechanism and Protection Technology of Multiple Sulfur Corrosion Phenomenon in Power Transformer

Abstract:Multiple active sulfides in the transformer oil could react with the copper conductor to form cuprous sulfide, which adheres to the surface of the copper wire and the insulating paper, reducing the oil-paper electrical properties and cause insulation failure. At present, most scholars mainly focused on the corrosiveness of the single sulfide DBDS, while few on other sulfides and their synergistic deterioration effects. Based on the macroscopic experiment and microscopic molecular simulation, the project intends to analyze the change rule of aging characteristic parameters under different sulfide, voltage and temperature, to clarify the reaction process and their mutual conversion of multiple sulfur corrosion. Also, the synergistic deterioration mechanism of the oil-paper insulation by different sulfurs would be revealed. By extracting the decoupling characteristic parameters which can quantitatively characterize the multiple sulfur corrosion degree, the mathematic correlation model of the sulfur compositions, the aging characteristic parameters and the sulfur corrosion severity can be established, also with the quantitative characterization method of the sulfur corrosion severity degree. The protection effectiveness of passivator under multiple sulfur corrosion would be studied and the optimal passivator concentration for different corrosive sulfurs will be proposed. This project has certain scientific significance and application value for further revealing the sulfur corrosion phenomenon and its synergistic degradation mechanism, as well providing theoretical basis and technical means for preventing the sulfur corrosion insulation fault.

Speech Title:Variability compensation through green hydrogen for variable renewable energy systems

Abstract:This webinar presents an overview of the main characteristics of energy sources and requirements for the proper operation of power systems. The core of the webinar is a detailed overview of the hydrogen-based variable renewable energy systems for large-scale standalone operations. Details of the Power-to-Hydrogen-to-Power (P2H2P) and Power-to-Fuel-to-Power (P2F2P) systems are given from technical and economical points of view. In addition, simplified mathematical models are presented for estimating the steady-state and energy efficiency performances of various components comprising P2H2P systems. An energy management (or power plant controller) algorithm is also provided for illustrating the operational modes of these systems and the energy balance of various operational modes. Main research & development (R&D) requirements for providing reliable systems are also determined. The survey shows that P2H2P and P2F2P systems are expected to be techno-economically feasible enough to totally replace conventional fossil-based electric power generation technologies.
