凸极同步电机静态稳定极限线的推导和计算机绘图

Steady Stated Stability Limit Derivation and Computer Aided Drawing for Salient-pole Synchronous Generator

从凸极同步电机基本电磁关系的相量图出发,推导了凸极同步电机理论静态稳定极限线、实际静态稳定极限线的数学表达式,并给出了计算机绘制相应图形的方法。目的在于对此问题建立出清晰的数学模型,同时利用计算机更快更准确地进行相关曲线的绘图,相对以往的手工做图法是一个较大的改进,具有较强的工程实用价值。

This article starts from the phasor diagram of basic electromagnetic relatitms of saliency synchronous electrical machine, deducing the power graph of whitch, the mathematical expression for theoretical static steady limit line and pratical static steady limit line. The article also provides the method of using computer to draw the corresponding graph. The purpose of this article is to establish a clear mathematical model for this question and simutaneously plot the relevant curve using computer more quickly and more accurately. Compared to the traditonal handmade chart, it has made great improvement with considerable engineering value.
