Abstract: Abstract:In the oversea power projects undertaken by china enterprises, the situations of the local power system are unknown for the china enterprises sometimes. The shortcircuit characteristics of the projecttopower grid system connecting scheme was discussed and analyzed. According to the assumed condition and to actual condition, the shortcircuit calculations were carried out separately. The shortcircuit calculation results were analyzed and compared, and the deviation of the shortcircuit analysis was given.

Key words: Keywords:unknown, shortcircuit analysis, perunit value, power system
