Analysis of Steady-state Characteristics of Thermal Subsystem in Integrated Energy System

open access: yes发电技术, 2020
The integrated energy system (IES) includes various energy forms, complex operation modes, abundant control equipment and coupling links, which brings challenges to its steady-state modeling and steady-state power flow calculation. In order to obtain the

Forced Unsteady State Operation of a Catalytic Converter during Cold Start-up for Oxidizing CO Over Pt/γ-Al2O3 Catalyst [PDF]

open access: yesMATEC Web of Conferences, 2021
CO oxidation in the catalytic converter hasn’t showed best performance particularly during cold start-up, since the catalyst is not active during this period.

Two-inductor Boost Converter Start-up And Steady-state Operation

open access: yesEletrônica de Potência, 2010
In this work, an isolated DC/DC two-inductor boost converter is proposed. The topology is able to start up and operate in steady-state at any output level within 0V to 400V.

Energy-Based State-Space Representation of Modular Multilevel Converters with a Constant Equilibrium Point in Steady-State Operation

open access: yesIEEE transactions on power electronics, 2018
The internal currents and voltages of modular multilevel converters (MMCs) contain multiple frequency components in steady-state operation and remain time-periodic even when transformed into a synchronously rotating reference frame.

Effects of propeller load fluctuations on performance and emission of a lean-burn natural gas engine at part-load conditions

open access: yesPropulsion and Power Research, 2022
Providing stable combustion of lean-burn natural gas engines was always a big challenge, particularly during a low load operation. In transient sea conditions, there is an additional concern due to irregular time-varying loads.
