The aim of this paper is to present a nonlinear dynamic model for Voltage Source Converter-based HVDC (VSC-HVDC) links that can be used for dynamic studies. It includes the main physical elements and is controlled by PI controllers with antiwindup. A linear control model is derived for efficient tuning of the controllers of the nonlinear dynamic model. The nonlinear dynamic model is then tuned according...
This paper introduces a simplified HVDC model developed for modeling the steady-state and the dynamic behavior of a voltage-sourced converter based on the modular multilevel converter design. The simplified model is intended for time domain simulations in a positive sequence dynamic simulation program. The model is used for dynamic stability studies and performance analysis of the HVDC within a large...
This paper presents a new approach for the modeling and dynamic control of the back-to-back systems which are based on voltage source converters. The state-space average method is used to derive the non-linear model of the system. Through a non-linear transformation and power balance fact a linear model for the system is developed. It is shown that DC link of the system can be regulated only from...
This paper presents a steady state performance analysis carried out to study the behavior of a two VSC-based operating as a single-input single output HVDC link. The digital model of the HVDC link has been implemented and evaluated using PSCAD/EMTDC. The emphasis of this research work has been focused on evaluating the transference of active power from the rectifying station to the inverting station...
Article on a novel approach to providing on route power supplies to rural and urban communities in close proximity to the extra high voltage DC transmission line; in addition to on route country bulk transfers and country point to point bulk transfers.
This paper investigates advantages of new combination of the induction generator for wind power and the power electronic equipments. Induction generator is popularly used for the wind power generation. The disadvantage of it is impossible to generate power at the lower rotor speed than the synchronous speed. To compensate this disadvantage, expensive synchronous generator with the permanent magnets...
