Synchronous Generator Emulation Control Strategy for Voltage Source Converter (VSC) Stations

IEEE Transactions on Power Systems, 2015
The voltage source converter (VSC) station is playing a more important role in modern power systems, but the dynamic behavior of the VSC station is quite different from that of the synchronous generator. This paper presents the synchronous generator emulation control (SGEC) strategy for the VSC-HVDC station.

STATCOM model in EMTP RV using hysteresis current controlled voltage source converter (VSC)

Canadian Conference on Electrical and Computer Engineering, 2005., 2006
In this paper, a static compensator (STATCOM) model in EMTP RV of a voltage source converter (VSC) is presented. The STATCOM is connected to the end of a transmission line. The DC/AC conversion is obtained by using pulse width modulation (PWM) based on a current hysteresis controller.

Square of Voltage Out-Loop Based Feedback Linearization Control of Voltage Source Converter (VSC) in SMES

Advanced Materials Research, 2013
To improve the response characteristic of the VSC in SMES (Superconducting Magnetic Energy Storage) with wide load disturbance, a new square of voltage out-loop based feedback linearization control strategy is proposed for the control of VSC. The input variable was controlled by a combining of square of voltage out-loop based direct voltage control and

Voltage Source Converter (VSC) HVDC for bulk power transmission - technology and planning method

9th IET International Conference on AC and DC Power Transmission (ACDC 2010), 2010
As the value of additional functionality of any new power technology is very case dependent, it is not possible to make general comments on the economics of VSC HVDC applications for bulk power transmission without considering alternatives. Therefore, the paper presents a methodology which can be used to evaluate different investment options, based on ...

DC overvoltage control during loss of converter in multiterminal voltage-source converter-based HVDC (M-VSC-HVDC)

IEEE Transactions on Power Delivery, 2003
Security requires that a system continues to function even when any one subsystem fails. A multiterminal HVDC system consists of N voltage-source converters (VSCs) exchanging power through a DC network. When any one converter is lost, before the surviving (N-1) converters have time to re-establish a new power balance, the excess DC power can produce ...
