         Abstract In view of some influencing factors such as motor starting capacity，distribution line，operated load and the characters of generator etc.，this paper discusses the capacity check（in the strict sense）of diesel generator in civil buildings，and puts forward as well as deduces several check formulas，and introduces its application in specific projects.

        Key words　Diesel generator　Fire protection load　Operated load　Allowable voltage drop　Starting capacity　Check　Steady calculated load

        摘　要　考虑电动机启动容量、配线、已接负荷和发电机特性等诸多影响因素，探讨严格意义上的民用建筑中柴油发电机容量校验，提出及推导若干实用校验公式，并介绍其具体应用。

        关键词　柴油发电机　消防负荷　已接负荷　允许电压降　启动容量　校验　稳定计算负荷
