基于改进单纯形算法的 HSVS补偿系统自适应 PID控制研究

摘要

In this paper ,a new type of hybrid static reactive power compensation system ( HSVS ) is designed based on the characteristics of MSC ,TSC and TCR so to keep MSC ,TSC and TCR work at rough ,fine and very fine tuning respectively .For solving coordination problem of PID control among them,improving control accuracy and system robustness ,learning function is introduced into the sim-plex algorithm as a PID parameter ,the step adjustment and measurement introduction of simplex algo-rithm is improved .It is shown by simulation test that compared with general adaptive PID controller ,it improved feasibility and high efficiency of adaptive control of simplex algorithm in the voltage control of hybrid reactive compensation system and enhances compensation accuracy and adaptability .%结合机械投切电容器（ MSC）、晶闸管投切电容器（ TSC）及晶闸管相控电抗器（ TCR）特性，本文设计了1种新型的混合型静止无功补偿系统（ HSVS ），使MSC、TSC、TCR分别工作在粗调、细调和精调的工作模式。为解决PID控制对这三者的配合问题，提高控制精度与系统鲁棒性，引入了单纯形算法作为PID参数的学习函数，并对单纯形算法的步长调整以及测度引入加以改进。仿真实验证明，与普通的自适应PID控制器相对比，改进了单纯形算法的自适应控制在混合型无功补偿系统电压控制中的可行性与高效性，提高了补偿精度与适应性。
