【摘要】 本文针对d、q、O系统及a、β、O系统在电机理论分析中的优点及不足,综合提出了一种“旋转-静止”坐标系统,即d、g、β₀系统,建立了该系统下的同步电机数学模型,并介绍了这一模型对电机暂态过程进行仿真计算时的应用方法。结果表明,本系统模型具备前两种系统模型的优点,在电机的仿真计算中尤为有效。用该模型对短路故障进行计算的结果已被实验证实。更多还原

【Abstract】 Owing to the reliability of evaluation as well as in saving computation time, the transformation research is still attractive and preferable for studying transient behaviour of electrical machines. A "rotating-stationary" reference frame, named as d, q, β₀ system, is proposed in the paper, and a new mathematical model of synchronous machine is thereby established. Applications provided for the digital simulation of synchronous machines during symmetrical and asymmetrical disturbances show that the d, q, β₀ system can combine the merits of both d, q, 0 and α, β, 0 systems. The calculation results have been verified by comparison with the test results.更多还原
