【摘要】：多变量耦合问题的存在给大型电力工程项目实施状态的宏观分析与决策带来极为不利的影响.针对这一问题,本文首先对系统多变量在工程项目实施状态变化过程中的耦合机理进行了数理分析与描述,并建立和确定了能够有效反映系统多态多变量耦合结果的泛性方程.然后,通过对该方程的分解性分析,发现了求解系统多变量耦合问题的两个关键参数.通过包含多变量耦合结果泛性方程的拉氏变换以及与能够有效表达工程实际管理需求且含有系统期望配置极点参数的拉氏方程之对比,获得了这两个参数的解,并在此基础上给出了能够有效解决系统多变量耦合问题的拉氏解径.工程实证结果表明,该方法在分析和处理系统多变量耦合问题方面不仅可行有效,而且精度很高.
[Abstract]:The existence of multivariable coupling problem has a very negative impact on macro analysis and decision making of large power engineering projects. In this paper, the coupling mechanism of multivariable system in the process of project implementation state change is analyzed and described. The universal equation which can effectively reflect the results of multivariable coupling of the system is established and determined. Then, the decomposition of the equation is analyzed. Two key parameters for solving the multivariable coupling problem of the system are found. The Laplace transformation of the universal equation containing the multivariable coupling results and the Lagrangian transformation can effectively express the practical management requirements of the engineering and contain the desired poles of the system. A comparison of the Lagrangian equations of the parameters. The solution of these two parameters is obtained, and the Lagrangian solution path which can effectively solve the multivariable coupling problem of the system is given. This method is not only feasible and effective in the analysis and processing of multivariable coupling problems, but also has high accuracy.
