摘　　要：整定计算软件中运行方式的选择存在着全面性和合理性的困难。提出了把整定计算中的运行方式分解为厂站大小方式、供电方式和检修规则三者的组合的分解方法。以计算最小助增系数时运行方式的选择为例介绍了厂站方式、供电方式和检修规则的选择方法和理论依据。最后以复杂环网结构实例分析说明了这种分解方法能缩小运行方式的选择范围并保证选择合理,便于计算机编程实现,从而有效减少故障计算的次数和提高整定计算结果的正确性。There are problems about amount and rationality in setup and choice of operating mode of setting calculation software. The new idea of taking operating mode as the combination of running mode of plant or station, power supply topological and rules of equipment maintenance is put forward, which is more believable because of combining user setting with computer auto setting. How to select the running modes of plant or station, power supply topological and rules of equipment maintenance are analyzed, taking minimum calculation of sideline current addition coefficient as an example. The results show that this method can reduce the range of choice and ensure a reasonable result, so it can reduce the time of fault analysis and improve the correction of relay setting.
