With the advance of insulated gate bipolar transistor (IGBT) converters, Multi-Terminal DC (MTDC) based on the voltage-source converter (VSC) has developed rapidly in renewable and electric power systems. To reduce the copper loss of large capacity and long distance DC transmission line, an improved droop control design based on optimal power sharing in VSC-MTDC integrating offshore wind farm i...

Gas-insulated equipment is an important part of the power system owing to its advantages small footprint, large transmission capacity, and high reliability. Detection insulation defects partial discharge (PD) for operation maintenance, combination multiple detection methods can greatly improve accuracy PD detection. In this study, three kinds defects, namely, floating defect, void surface are s...

This paper presents a 3D transmission line matrix (TLM) implementation for the solution of transient heat flow in power devices. The miniaturization of electronic networks creates problems of heat dissipation. Good thermal management is therefore essential. Simulating power electronic systems presents peculiar challenges due to the need of detailed modeling of both circuitry and control algorit...

in this paper, shielding effectiveness (se) of a perforated enclosure with imperfectly conducting walls is evaluated. to this end, first, an accurate numerical technique based on method of moments (mom) ispresented. in this method, lossy metallic walls of the enclosure are replaced by equivalent electric surfacecurrent sources. then, the impedance boundary condition on the imperfectly conductin...
