碩士 === 聖約翰科技大學 === 自動化及機電整合研究所 === 96 === This study reports to go into detail the system of the electric power quality to develop condition currently and is used as to analyze the result of the electric power quality and makes use of the machine electricity actual situation of the electric power quality of the equipment improvement by solid example explanation to the usage electric power supervision system and the software.The supervision system of the electric power quality in nowadays has already not only been the false search of after the event and made up, but synchronously supervised and controled to avoid to the whole distance of the electric power system electric power bug and can not know, carry on an improvement under the most instant status.Modern science and technology industry produces equipment nicety and sensitive, the electric power quality badly will make part of sensitive electrical appliances or electronic instrument lockout and extension launched to each electric power to make a huge sum of lost, and the serious may also cause surprised work Anne's accident to cause the injury that can't make up. The electric power quality analysis improvement concerns to arrive extremely and extensively to the theories of the electric power system and included among them electric generate electricity fraction, transmission fraction and allocation fraction and voltage harmonics distortion and current harmonics distortion. For improving electric power quality, we have to aim at to investigate the problem place of the electric power quality and find wrong reason, then basically look for to turn down the valid project of its influence.We collect first of a great deal of quality condition data need to take into the data of the covariance integration to analyze with the forerunner's analytical mode, this text will enumerate each kindof electric power quality variety, and use to the mode of category of supervising and controling the measurement and the discretion electric power quality variety, we explain first that the fundamental of the electric power quality all says, then introduces the analytical content of science and technology factory solid example case study, and puts forth the forerunner's supervision method and how will analyze a result to carry on case suggestion and improvement further.
