The Enhanced DC Fault Current Calculation Method of MMC-HVDC Grid With FCLs
IEEE Journal of Emerging and Selected Topics in Power Electronics, 2019This paper introduces an enhanced dc fault current calculation method for modular multilevel converter-based high-voltage dc (HVdc) grid. The new method considers the fast switching of the fault current limiters (FCLs) and the nonlinear characteristics ...

A Calculation Method of Pseudo Extinction Angle for Commutation Failure Mitigation in HVDC
IEEE Transactions on Power Delivery, 2019This letter presents a novel pseudo extinction angle (PEA) for the HVDC inverter, as well as its calculation method. The proposed PEA extends the measured extinction angle (EA) into a real-time calculated value.

Method for calculating alloy energetics
Physical Review B, 1992A semiempirical method for the computation of alloy energies is introduced. It is based on the equivalent-crystal theory of defect-formation energies in elemental solids. The method is both simple and accurate. Heats of formation as a function of composition are computed for some binary alloys of Cu, Ni, Al, Ag, Pd, Pt, and Au using the heats of ...

Energy hub (EH) model, which connects the input and output energy by using the coupling matrix, is an important model for multiple energy system (MES) study. In a complex MES, it is very difficult to formulate the coupling matrix directly.

Improved Calculation Method for Insulation-based Fire Resistance of Composite Slabs.
Fire and Materials, 2019Floor slabs play a critical role in the fire resistance of buildings, not only by maintaining structural stability and integrity, but also by providing thermal insulation to limit the rise in temperature of floors above a fire.

Analytical Calculation Methods
2010Although numerical calculation methods for solving Laplace’s equation have developed remarkably in the past few decades, analytical methods still have significance in obtaining precise values and in easily evaluating parameter dependence, for example.

Enhancing the Dutch engineering calculation method.
INTER-NOISE and NOISE-CON Congress and Conference Proceedings, 2023With the advent of new legislation, we have taken the opportunity to take a serious look at the Dutch national calculation method. This method, which is similar to ISO9613-2, needed enhancements to allow for the increasingly complex world outside. Objects like leaning barriers or diffracting elements on barriers are seen more and more. The 3D datasets
