摘　　要：当前已有的测控实验室节点电压校正方法的主导节点选择易出现较大偏差,导致电压校正精度不理想,且效率偏低。于是提出测控实验室区域主导节点电压校正方法。在测控实验区域构建多场景优化模型,获取随机场景。通过免疫遗传算法获取实验区域的主导节点,监测主导节点的电压数据变化,判断主导节点电压数据是否存在振荡现象。并利用离散系统模型等效分析主导节点电压,将系统特征根通过输出反馈方式转移到收敛区,在多次迭代计算过程中使主导节点脱离振荡,实现主导节点的电压校正。仿真结果表明了所提方法的主导节点校正效果好、误差小、效率高,能够增强测控实验室电压的稳定性,保障实验室区域的安全性。In this paper,a method to correct the voltage of pilot node in the measurement and control laboratory was put forward.At first,a multi-scene optimization model was constructed in the measurement and control experiment area to obtain random scenes.Then the pilot node in the experimental area was obtained by immune genetic algorithm.Meanwhile,the voltage data of pilot node werenitored to determine whether the voltage data has oscillation.Moreover,the discrete system model was used to equivalently analyze the voltage of pilot node.And the characteristic root of the system was transferred to the convergence zone through the output feedback.During multiple iterations,the dominant node was removed from the oscillation.Finally,the voltage correction for pilot node was achieved.Simulation results show that the proposed method can enhance the voltage stability of the measurement and control laboratory and ensure the safety of the laboratory area,with good correction effect,small error and high efficiency.
