“五区图”控制理论是一种控制对象与传统“九区图”完全不同的、面向未来电力系统硬件架 构的全新电压无功综合控制原理。文中在控制模型、控制边界、动作非启动区、控制盲区等方面对 “五区图”进行了更深入的讨论和改进,给出了软件实现框图,明确提出了基于控制效果预算,以操 作优劣距离为判据,面向电压无功综合控制(VQC)装置实际操作动作的控制思想,控制动作有了 明确的判据,不再盲目,VQC装置动作选择更加合理。通过与“九区图”理论的比较表明,面向实际 操作动作的“五区图”原理,控制精度高,控制效果好,应用前景广阔。
The “five-zone map” control theory is a completely different control object and the traditional “nine-zone map” for the future power system hardware architecture of the new voltage and reactive power integrated control principle. The paper discussed and improved the “five-zone map” in the aspects of control model, control boundary, non-actuating zone and control blind zone. The block diagram of the software was given. The control budget, In order to meet the requirement of VQC control, the control action has clear criteria and no longer blindness. The VQC device’s action selection is more reasonable. The comparison with the theory of “nine-area map” shows that the principle of “five-area map” oriented to practical operation has high control precision, good control effect and broad application prospect.
