摘要:
本文中,首先推导了以dq0、FB0、120、αβ0电流分量表示的同步电机状态空间方程;然后按不同运行方式下的边界条件对它们作修正;并用相应的数值方法求解。将这些数值解与常用解析公式的计算结果相比较,可见状态空间分析法有简单、精确、灵活等独特优点,有待继续发展为一个独立的领域。而文中所列计算步骤和计算公式则可起检验、概括、取代现有各种解析公式的作用。本文涉及的同步电机运行方式有:三相短路、自同步、异步并列、恒速异步运行、强制小值振荡、自振荡、自励磁、不对称短路、稳态不对称短路(谐波分析)。
Abstract:
In this paper, state-space equations of synchronous machine based on various sets of currents (dqo, FB0, 120, αβ0 components) as state variables are derived. These equations are then modified according to boundary conditions corresponding to different operating states, and these modified statespace equations are solved with appropriate numerical methods. By comparingthis approach with the analytical method, it is shown that state-space analysis combined with suitable numerical methods has its outstanding advantages of simplicity, accuracy, and flexibility. This approach should be further developed. The specific problems analyzed, together with the frames of reference used and the mathematical problems encountered, are as follows: a. Three-Phase Short-Circuit and Self-Synchronization Transients—dq0 frame of reference; initial value problem of ordinary differential equations: b. Constant-Speed Asynchronous Operation—FB0 frame of reference; solution of complex linear algebrie equations; c. Forced Small Oscillation—dqo frame of reference; solution of complex linear algebric equations; d. Self-Oscillation and Self-Excitation—dqo frame of reference: eigenvalue problem of real matrix equations; e. Unsymmetrical Short-Circuit Transients—αβ0 frame of reference; initial value problem of ordinary differential equations: f. Sustained Unsymmetrical Short Circuits (Harmonic Analysis)—120 frame of reference; solution of complex linear algebric equations.
