本文对高压直流系统的阻尼调制进行了理论分析。首先，通过一种能量函数揭示了直流调制的控制机理。利用残差，指出了决定调制效果的关键因素，从而深入了解了大型交/直流电力系统中直流阻尼调制的基本特性。提出了在直流调制中使用远程信号的方法。最后，通过对实际电网——南方电网的分析和仿真结果，为理论分析提供了依据。
A theoretical analysis on HVDC damping modulation is described in this paper. First, the control mechanism of dc modulation is revealed through a kind of energy function. Using residues, the key factor that determines modulation effect is then indicated which gives an insight into the basic properties of dc damping modulation in large-scale ac/dc power systems. Use of remote signals in dc modulation is proposed. In the end of the paper, analysis and simulation results in a real power grid, the China Southern Power Grid, provide evidence for the theoretical analysis.
