摘　　要：过程能力图是在过程能力指数基础上发展得到的新方法,较比传统的过程能力指数可以提供更多的关于过程分布和位置的详细信息,是过程及产品质量改进的有效工具。以电力行业中的电能质量为研究对象,通过使用过程能力图法,定量评估电能质量特性,该方法是电能质量综合评估的一种新尝试,将为用户选取供电方以及供电方合理地控制电能质量提供科学依据。A new method of process capability plots（PCP） is based on process capability indices（PCIs）, it is a powerful tool of quality improvement, and it can give us more information than only using PCIs in the traditional way, it provides about the location and the spread of the studied characteristics and the process simultaneously. On the background of power industry, choosing power quality characters as our study objects, process capability plot can be used to qualify the quality of power. It is a new method of synthetic evaluation for power quality（PQ）, and it＇s a better way not only for power users to select suppliers, but also for power suppliers to control the power quality.

关 键 词：过程能力图 过程能力指数 电能质量 综合评估
