发电机进相运行时计及AVR作用的静稳定限制

Static Stability Limits under the Underexcited Operation of the Generators in Consideration of AVR

按单机与无穷大系统,讨论了带有AVR并保持E_q′为恒定的发电机的电势向量及其随功角而变化的特性,导出了隐极式和凸极式同步发电机的静稳定功率极限方程式,并以算例阐明边界曲线的绘制,为有关问题的分析提供理论基础。

In this paper the EMF vector diagram and its change with the phase-angle are discussed for the nonsalient and salient pole synchronous generators with Automatic Voltage Regulator and constant E_(?)′ in one-machine infinlte-bus systems. The static stability limit equations of the two type generators are derived. The example is presented for drawing the static stability boundary curve.
