Cross_Bonded_Cable

Description:
Insulation coordination - 225 kV cross bonded cable - protection of the sheath.
In the configuration a 225 kV cross-bonded cable is connected at both ends to an otherhead line. The sheath is prot... see moreected by star-connected arresters.
The modelling used is adapted for the study of Fast-Front-Overvoltages (see IEC 60071)
A current source, with a CIGRE concave shape (See CIGRE 63 document), representing a lightning stroke has been connected to a tower close to the cable.
The case includes the modelling of the different elements of the configuration (cable, spans, arresters...).

CB_arc_CM

Description:
This is an interesting case of the study of arc-circuit interaction in case of the interruption of a short-line fault.The arc is represented by a composite Cassie-Mayr model and the line is represente... see mored as frequency-dependant.
The case shows the application of black-box arc modeling in the study of kilometric-line fault capability of a 420 kV circuit-breaker. By zooming on the arc current and voltage near current-zero, post-arc current and initial TRV may be visualized in both cases of clearing and thermal failure.

A Tool for Steady-State and Dynamic Analysis of PV Generation in Low Voltage Grids

Description:
Authors:
Dennetière S., Mahseredjian J., Duvauchelle C., Tounsi B.
This paper describes a tool based on EMTP-RV that simulates the steady-state and the dynamic behavior of photovoltaic (PV)... see more units on a low voltage grid. The tool takes into account load and irradiance curves to evaluate the impact of PV units on the voltage profile along the grid as well as the dynamic behavior of PV inverters. This tool has already been used to analyze and explain undesired disconnections of PV units in an existing system.

Induction machine modeling for distribution system analysis using initialization and time-domain methods

Description:
Panel session paper to be presented at the IEEE T&D show in New Orleans (Oct. 2005)
Authors: J. Mahseredjian, S. Dennetière, B. Khodabakhchian and A. Xémard
Abstract:
This pap... see moreer is presented as part of an effort by the Distribution System Analysis Subcommittee to establish reference cases for induction machine modeling in distribution system analysis and unbalanced three-phase systems. This panel paper presents analysis results obtained when applying a full time-domain method with load-flow and steady-state initialization. The selected software is EMTP-RV. Problem solution complexities are discussed.
