A basic eguation for predicting 500 mb topography is obtained on the followingtwo assumptions:(1)the level of P=O is a horizontal plane,(2)its height H doesnot change with time.This equation is very similar to that for barotropic case,but withcertain essential differences.In this article,author also points out that in the barotropiccase,taking a smaller grid we will get a better result than that of alarge grid.Theexamples of forecasting show that this method is rather successful.

在本文中,作者为了避免500mb 位面是无辐散的假定,引用了在大气顶 P=0处高度 H随时间变化很小,而且此位面几近于一个平面的假设,经过一些变化后,便得出了500mb 形势预告的方程,这个方程与正压涡度方程很相似,尤其当柵格取得小些时(例如600km),这个方程便较接近于正压预告方程,但二者是有本质上的区別的.于此文中,作者并指出在正压模式中,柵格取得小些时,可以得到较好的结果.从实例来看,这个方法是有些成功的.

Starting from the fundamental equations of electric machine, this paper develops an analytic method of investigation of the self-excitation problem of asynchronous machine connected through series capacitor. Constant synchronously rotating system components dc and qc and method of small oscillational equations are used in the analysis; steady state oscillational principles, spectrum frequency analysis of discriminating occurrence of self-excitation are discussed. Correlation between these methods are also described....

Starting from the fundamental equations of electric machine, this paper develops an analytic method of investigation of the self-excitation problem of asynchronous machine connected through series capacitor. Constant synchronously rotating system components dc and qc and method of small oscillational equations are used in the analysis; steady state oscillational principles, spectrum frequency analysis of discriminating occurrence of self-excitation are discussed. Correlation between these methods are also described. Results obtained from this theoretical analytic method are compared with those obtained from experimental tests, the agreement between them is very close. It is found that the basic nature of self-excitation phenomenon of asynchronous machine, as shown from the results of this investigation, is a kind of resonance among the electro-mechanical parameters of the machine. Traditional methods of analysis, being used so far by many writers, regarding the speed of the machine as a constant factor, cannot reveal the effect of rotational inertia of the machine upon the self-excitation process.

本文从电机基本方程出发,介绍了与串联电容相联的异步电动机的自激区的分析方 法。分析中利用了同步恒速转动坐标系统dc,qc分量及其微干扰方程式;同时还讨 论了稳态小值振荡理论、判别自激的频率法和这些方法的内在联系。理论分析所得结 果与实验数据相当一致。研究结果表明,异步电机的自激本质上是一种机电参数共振现 象.过去惯用的把电机转速视为恒值的方法不能反映电机惯性常数等因素对自激的影 响。

Results obtained from this theoretical analytic method are compared with those obtained from experimental tests, the agreement between them is very close. It is found that the basic nature of self-excitation phenomenon of asynch-ronous machine, as shown from the results of this investigation, is a kind of resonance among the electro-mechanical parameters of the machine. Traditional methods of analysis, being used so far by many writers, regarding the speed of the machine as a constant factor, cannot reveal the effect of rotational inertia of the machine upon the self-excitation process.

本文从电机基本方程出发,介绍了与串联电容相联的异步电动机的自激区的分析方法。分析中利用了同步恒速转动坐标系统d_c,q_c分量及其微干扰方程式;同时还讨论了稳态小值振荡理论、判别自激的频率法和这些方法的内在联系。理论分析所得结果与实验数据相当一致。研究结果表明,异步电机的自激本质上是一种机电参数共振现象,过去惯用的把电机转速视为恒值的方法不能反映电机惯性常数等因素对自激的影响。
