摘要为实现交直流互联系统低频振荡的有效抑制,提出一种基于滑模变结构控制理论的直流调制与静止同步补偿器（STATCOM）统一阻尼协调控制策略。首先建立包含高压直流（HVDC）与STATCOM的交直流系统惯性中心模型,整体考虑互联系统阻尼,并引入滑模控制理论设计统一阻尼控制策略;其次将直流调制和STATCOM附加控制对STATCOM电压控制回路的相对增益、惯性转速差作为目标函数,协调优化分配HVDC与STATCOM参与阻尼控制的权重,实现在抑制系统阻尼效果最佳的同时使系统电压保持稳定。最后,利用PSCAD建立四机两区域仿真模型,证明了该控制策略的正确性及有效性。

Abstract：In order to suppress the low frequency oscillation effectively in AC-DC paralleling transmission, a strategy based on sliding mode control theory is proposed to coordinate supplementary control between HVDC and STATCOM. Firstly, the mathematical model of multi-machine AC-DC parallel transmission system, including HVDC and STATCOM, is established through COI (center of inertia) method. To stabilize the COI angular velocity deviation between areas, the unified damping control strategy based on sliding mode variable structure theory is designed. And then, COI angular velocity deviation and relative gain array are taken as the objective functions, which are obtained from the supplementary control of HVDC and STATCOM on the STATCOM voltage controller. The purpose is to coordinate and allocate the participation weights of HVDC and STATCOM damping control. The coordination strategy guarantees the stability of voltage and realizes the optimal effect of damping control. Finally, the simulations of 4-generator 2-area model in PSCAD have verified the control strategy.
