摘要

提出了一种采用割线法控制直流电压和无功功率的高压直流输电系统的谐波域模型。采用比例积分(PI)控制方案对割线法的结果进行验证。结果表明,与PI控制方案相比,后者可以节省计算量。应用PSCAD/EMTDC软件工具对谐波和稳态波形进行了分析和验证。

Secant Method Applied to Control of HVDC in the Harmonic Domain
This paper presents a harmonic domain (HD) model of a high-voltage direct current (HVDC) system including controls for DC voltage and reactive power via the secant method. The proportional-integral (PI) control scheme is used to verify the results by the secant method. It is shown that the latter achieves computational savings compared to the PI control scheme. A case study is presented and verified with the PSCAD/EMTDC software tool in terms of harmonics and steady state waveforms.
