针对TSC动态无功补偿对动态负载的检测与响应速度较慢以及无法实现完全的无功补偿等问题，构建基于牛顿迭代控制的分区动态无功补偿系统仿真模型。本模型在控制量与无功补偿功率函数关系拟合的基础上采用牛顿迭代及优化控制进行求解，并通过补偿无功区间判定实现快速动态无功补偿。仿真实验结果表明，本系统能实现固定负载和动态无功负载的实时、快速、连续无功补偿，且稳态误差小、响应速度快。

In view of the slow detection and response speed of TSC Dynamic Reactive Power Compensation to dynamic load and the failure to realize complete reactive power compensation, a simulation model of dynamic reactive power compensation system based on Newton iterative control is constructed. On the basis of function relation fitting between control variables and reactive power compensation power, the model is solved by Newton iteration and optimal control, and fast dynamic reactive power compensation is realized by judging the compensation reactive power interval. The simulation results show that the system can realize real-time, fast and continuous reactive power compensation of fixed load and dynamic reactive load, with small steady-state error and fast response speed.
