电力系统连续体和离散模型中机电扰动传播的一致性研究
Study on Consistency of Electromechanical Disturbance Propagation in Continuum and Discrete-Models for Power Systems
摘要
Abstract
Continuum electromechanical wave theory is a novel modeling approach for studying the electromechanical dynamic characteristics of large-scale power systems. Based on the theoretical derivation, the equations and their propagation characteristics of electromechanical wave in the continuum model and electromechanical disturbance in the discrete model for power system are studied in this paper. At the same time, the one-to-one correspondence relations of those main physical parameters, including propagation velocity, critical velocity, propagation constant, characteristic impedance, reflection coefficients, in the two models are also analyzed profoundly. The results show that the propagation of electromechanical disturbance between the two models of power system have the almost same physical properties, which proves the continuum model is a kind of approximate method of the discrete model, and can be completely utilized to describe the dynamic characteristics and the internal mechanism of electromechanical disturbance propagation in a vaster spatial dimension.关键词
