Abstract
The system considered in this book is given in Fig. 5.1. The HVDC system consists of two VSCs connected via a DC link. The control of converter VSC-1 is done by using DC voltage control, whereas the control of converter VSC-2 is done by active power control. In this chapter, the steady-state and transient behavior of control schemes in normal and fault conditions a VSC-based HVDC connected to a grid is studied. The mutual effect between the VSC-HVDC performance and its control scheme dynamics is investigated. It is that the control scheme that uses is vector control and hysteresis current control. The different methods of calculating the reference current to control VSC behavior under different disturbance conditions are investigated. Different types of faults and protection scheme of VSC are also investigated.
