关于TCR+FC型SVC的研究文献，这篇文章考查了晶闸管控制的并联补偿器的理论基础。不平衡负荷补偿和电压稳定的条件是建立在对称分量的应用上的。适用于前馈控制（电脑的）的数学关系是根据。这里对前馈和反馈的实用方法进行了讨论。(This paper examines the theoretical foundations of thyristorcontrolled shunt compensation. Conditions for unbalanced load compensation and voltage stabilization are established with the use of symmetrical components. Mathematical relationships applicable to feedforward (computational) type controls are derived. Practical approaches to both feedforward and feedback type controls are discussed.)

一本关于介绍2015年发表的关于扩展有限元的SCI论文的论文集书籍，非常实用(In the standard FEM, cracks are required to follow element edges for the discontinuity modeling. In contrast, the crack geometry in the extended finite element method (XFEM) need not be aligned with the element edges and thus is independent of the background mesh.)
