摘　　要：在综合电能质量监测、分析与管理系统中,由于电能质量的时、频域参数众多,并且是多路监测,其数据量较大,非常适合采用数据库的形式进行管理。本文主要针对电能质量参数的数据库管理方式,在指出两层C/S结构所存在问题的基础上,提出了三层C/S结构,并对其不同连接方案进行论证、分析,从而确定出适合电能质量数据库管理系统的解决方案。Lots of data will be needed in the process of developing the synthetic moni-toring,analyzing and managing system of power quality due to the diverse parameters of power quality in time domain and frequency domain.Recently the authors are the mem-bers who develop the synthetic monitoring and analyzing system of power quality.In this paper the defects of the two-tier Client/Server structure is first pointed out and then three-tier Client/Server structure is put forward,and the different connecting programs are also analyzed and discussed late in the paper.In this way the solution program that is suitable for the management system of the power quality database is chosen.
