中文摘要
      针对一管多机系统中水力耦合下多机协同控制不足的问题,本文提出一种基于协同控制理论的多机协同 镇定控制策略,用于建立多机联系.首先,重新考虑共用管道的动态水头耦合变化项,构建包含多台机组状态变量的 宏变量,以多机主要状态变量的输出偏差为控制核心来预设平衡点.然后,将宏变量代入控制流形,推导出新形式 的耦合水头项,将原有线性模型转化为非线性模型来跟踪机组变化.通过与原形式输出状态对比验证了所提策略 在降低机组输出振荡、增强系统孤网运行稳定方面表现优异,为水力耦合的处理提供了可行的解决方案.
英文摘要
      Aiming at the problem of insufficient multi-unit synergetic control under hydraulic coupling in the single penstock multi-machine system, this paper proposes a multi-unit synergetic calming control strategy based on synergetic control theory for establishing multi-unit linkage. First, the dynamic head-coupling change term of the shared pipeline is reconsidered, and the macro-variables containing the state variables of multiple units are constructed. The equilibrium point is preset by taking the output deviation of the main state variables of multi-unit as the control core. Then, the macro variables are substituted into the control manifold to derive a new form of coupled head term, which transforms the original linear model into a nonlinear model to track the unit changes. By comparing the state outputs in the original form, it is verified that the proposed strategy performs well in reducing the output oscillations of the unit and enhancing the stability of the system’s isolated network operation, which provides a feasible solution for the treatment of hydraulic coupling.
