配电网静止无功补偿器(DSVC)是综合治理电能质量问题的有效装置，其多个装置间的交互影响问题应予以考虑。以含两台DSVC的简单配电系统为研究对象，建立了考虑感应电动机负荷的含两台DSVC的单负荷无穷大配电系统线性化模型，在此模型的基础上推导得出系统传递函数矩阵，并运用基于奇异值分解(SVD)的方法，定量分析了在不同电气参数下两台DSVC的交互影响问题。通过SVD计算，得到了交互影响随电气距离的缩短而增大的结论。通过时域仿真，验证了SVD计算所得的结论，表明了所建线性化模型及SVD方法的有效性。

As distribution static var compensator (DSVC) can synthetically manage power quality problems, the interactions among the DSVC controllers should be considered. The paper establishes the linearized model of a single-load infinite-bus distribution system installed with two DSVC considering the induction motor load, and the system transfer function array can be obtained based on this model. Then, the singular value decomposition (SVD) method is used to analyze the interactions under different electrical parameters, drawing a conclusion that the interactions will be strengthened when the electrical distances are decreased. The simulation results verify the effectiveness of the proposed model and the SVD method.
