“…The fault recovery characteristics of the HVDC system feeding a strong AC network [11] is carried out using advanced digital power system simulator (ADPSS) during DC line fault and the inverter bus fault conditions. The DC power recovery and suppression of temporary overvoltage (TOV) of an HVDC system feeding a weak or very weak AC network [12][13][14] has been discussed. To make the analysis complete, it is highly necessary to consider the suppression of TOV for an HVDC system feeding a strong AC network too.…”

Transmission of electrical power through high voltage direct current (HVDC) has attracted the attention of a number of researchers in the recent years. For economic design and optimal operation, HVDC system requires a detailed simulation model. Therefore, in this paper a detailed Matlab simulation model of line commutated converter (LCC) based monpolar HVDC system, feeding a strong AC network, with a fixed capacitor (FC) as a reactive power compensator is presented. Firefly algorithm based optimal proportional integral (PI) controller has been proposed for the rectifier and the inverter control. The transient performances of the HVDC system under various AC and DC fault conditions were studied. The results show the supremacy of the firefly algorithm based optimal PI controller over the conventional PI controller. The harmonic analysis is also carried out under steady state operation to assure the quality of power supply on the inverter AC side.

“…As shown in Figure 1, the AC network parts of the HVDC study system and its DC controls are identical to those in the CIGRE benchmark model except for the STATCOM that is added to the AC bus bar at the in-verter end [5][6][7].…”

This paper deals with the stability problem at the inverter end of a HVDC link with STATCOM (Static Compensator), when connected to a weak AC system which has the stability enhancement for power instability and commutation failures. The HVDC stability problem is tackled with a STATCOM which not only provides a rapid recovery from power, harmonic stability and commutation failures but also offers a lower cost filter design for the HVDC system. PSCAD/EMTDC simulations are presented to demonstrate the robust performance and to validate the proposed topology.
