Abstract
Efficient and economic power delivery through HVAC transmission system over long distance is a great challenge due to its physical and operational constraints. HVDC systems are preferable for long-distance transmission due to the technical and economic superiority over HVAC systems. This paper further efforts supporting long-distance power transmission using bipolar HVDC system based on current source converter technology. In this regard, a novel control circuit for converters at both sides of the proposed system is presented. Then using E-HVAC system along with proposed HVDC system, a composite E-HVAC and HVDC model is presented where a transmission line in E-HVAC system is replaced by HVDC system. This composite E-HVAC and HVDC system covers the limitations of both systems when operating separately. Finally, the power upgradation and stability of composite E-HVAC and HVDC system and its behavior under transient instability is studied, and the results illustrate the effectiveness of proposed model under normal and abnormal conditions.
