High voltage direct-current (HVDC) transmission plays an important role in China's regional power grid interconnection, effect of alternating-current (AC) system strength on the HVDC startup characteristics is gradually emerging.According to the study about HVDC start-control, this paper builds a simulation model to study the characteristics of its startup based on PSCAD/EMTDC simulation program. For the simulation results, this paper puts forward some solutions when HVDC is connected to extremely weak AC systems and compares them.

“…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.

“…However, it is prone to suffer from commutation failure (CF) and cascaded CFs in multi-in feed scenarios [2]- [4]. Many reactive power compensators are considered to be utilized to regulate the AC bulbar voltage at the inverter side to mitigate the CFs of LCC-HVDC link [5]- [7], and one potential option is the utilization of Voltage-Source-Converter (VSC) type STATCOM device [6].…”

Abstract. This paper develops a linearized small-signal dynamic model of a LineCommutated-Converter based HVDC (LCC-HVDC) system with STATCOM at the inverter busbar, and validates its accuracy by comparing time-domain responses from small-signal model and PSCAD-based simulation results. Considering the potential impact of Phase-Locked-Loop (PLL) parameters on the study system and the close connection of STATCOM and LCC inverter station at AC busbar, this paper investigates the impact of PLL gains and AC voltage control parameters of STATCOM on the system small-signal stability. The studies show that (i) the PLL gain has highly impact on the study system and smaller PLL gains are preferable; (ii) larger values of both the proportional gain and the integral gain of AC voltage controller of STATCOM could result in oscillation/ instability of the system.
