STATCOM model in EMTP RV using hysteresis current controlled voltage source converter (VSC)
Canadian Conference on Electrical and Computer Engineering, 2005., 2006In 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.

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), 2010As 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 ...

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 ...

2014 International Power Electronics and Application Conference and Exposition, 2014
In AC/DC hybrid grid, the individual AC and DC grids exist. The power converters are the key interfaces between these two kinds of individual grids. Under unbalance AC grid, the grid voltage is distorted and the harmonics is involved. Therefore, the active power and reactive power also give rise to the uncontrolled oscillations, which will damage the ...
