Many of these concerns are closely related to the AC voltage regulation at the converter bus. Generally, the associated reactive compensators and HVDC systems are operated and controlled independently and the interaction between them considered only under steady state condition. If the control become coordinates between the HVDC system and reactive power compensator, the performance in transient state and dynamic performance of HVDC system will be improved. The transient performance of HVDC system is very important. Since, the increasing demand of power in industries forced integration of HVDC system with AC system. After the development of FACTS controllers, the transmission capability becomes improved. These controllers improve the controllability and stability of power networks. STATCOM (Static Synchronous compensator) is one of the most important Flexible AC transmission system (FACTS) devices because of its ability to regulate voltages in transmission lines, to improve transient stability and to compensate variable reactive power. In this paper the topology which is considered is that the characteristics of the line-commutated HVDC with a STATCOM at the inverter end.
