摘要：
In this paper, the advantages and disadvantages of fixed series complement (FSC) and controllable series complement (TCSC) in long-distance transmission are analyzed in detail: FSC has the characteristics of improving line transmission capacity and increasing transient stability, but the control is not flexible enough, which may cause sub-synchronous oscillation and insufficient damping. TCSC has the characteristics of suppressing power Angle oscillation and improving transmission power limit. Considering the two factors of economy and efficiency, a method combining FSC and TCSC is proposed. Taking a typical single-machine infinite system as an example, TCSC adopts the linear control plus bang-Bang control strategy in BPA of China Electric Power Research Institute. According to the research, the transmission capacity of the line can be effectively improved by configuring series complement under different conditions, such as no series complement, only FSC and mutual supplement between FSC and TCSC, and with the increase of TCSC comparison, It is more obvious to resist functional oscillation.
