摘　　要：针对发电机进相计算中功角安全域难以快速精确计算的问题,提出了一种基于机端功率和系统电压的发电机功角安全域的快速计算方法。对于隐极机,通过消去功率方程中发电机内电势项,得到了隐极发电机达到极限功角时有功和无功功率关系。对于凸极机给出了稳定极限功角的解,并用该公式得到了凸极机的功角安全域。试验结果表明用所研究的计算方法得到的计算结果具有很好的精确度,可以满足进相计算的需要。To solve the problem of calculating synchronous generator leading phase operation pow?er angle safety region,a fast calculation method based on system voltage and terminal power is es?tablished in this pager.The analytical expression of non-salient pole generator leading phase opera?tionboundary is derived by eliminating the internal potential.The angle limitation calculation meth?od for salient pole generator is proposed,which is used to determine the angle safety region.The re?sults of simulation for two generators prove the precision and suitability of the proposed method forgenerator leading phase operation calculation.
