摘　　要：应用电力系统中长期动态仿真软件Eurostag进行时域仿真 ,将时域仿真确定的系统功率传输极限与BPA潮流计算的功率传输极限结果进行比较 ,研究影响功率极限的因素。研究表明 ,如果系统条件相同 ,两种方法获得的功率极限结果基本一致 ;如果不相同 ,则其结果要依系统具体条件而定。一般潮流计算不会考虑到系统中各种控制和保护装置的动作 。The paper acquires power transmission limit by time domain simulation used Eurostag, a software which covers the whole range of power system dynamic phenomena, and by power flow calculation used BPA. The results have been compared and analyzed for researching the factors affected on power transmission limit. The researches show that if the system conditions considered by the two methods are similar, they can get same results; if not, the results depend on the system conditions.
