Reactive Power Control Optimization of Ultra-high Voltage Direct Current Based on Topology of Self-adaptive Static Var Generator and Line Commutation Converter
While reducing the risk of commutation failure and enhancing the operation reliability of equipment in the line commutated converter (LCC)
the self-adaptive static var generator (SVG) and line commutation converter (SLCC) also saves land area in converter stations
which has broad engineering application prospects. This paper analyzes the fault response and power characteristics of SLCC
reveals the profound impact of SVG integration on LCC. Regarding the issue of passive and lagging responses in SVG caused by the independent control of LCC and SVG in SLCC
an optimal control strategy for SLCC is proposed
which considers the interaction and coupling effects between LCC and SVG. This strategy enables coordinated control between LCC and SVG
fully utilizing the fast adjustment ability of SVG. Based on the electromechanical-electromagnetic hybrid simulation software PSD-PSModel
the simulation results verify the rationality of the theoretical analysis
and the power characteristics of SLCC are improved with the proposed optimal strategy.
