Power quality monitoring

Summary form only given as follows. Today, power quality monitoring is an essential service many utilities perform for their industrial and other key commercial customers. Because of the technology and software now available, this monitoring is highly effective. Not only can a monitoring system provide information about the quality of the power and the causes of power system disturbances, but it can identify problem conditions throughout the system before they cause widespread customer complaints, equipment malfunctions, and even equipment failures. Power quality problems are not necessarily limited to the utility power system. Many surveys have shown that the majority of problems are localized within customer facilities. Given this fact, monitoring provides a key opportunity for a utility to protect its reputation and improve its relationship with customers. Essential requirements for a successful monitoring system include extensive data processing capabilities, easily understood reporting, and universal sharing of information. In this paper, we introduce a database management PQ software, equipped with statistical analysis and plotting tools and wrapped in a user-friendly interface. It consists of two major components, the Power Quality Data Manager and the Power Quality Data Analyzer. It offers users the ability to process and analyze many types of data by integrating all of the information from numerous monitoring devices into one relational database. It provides the means to automate the loading of new data using the Power Quality Data Manager Module, as well as provide the means to create automated and customized reports via the Power Quality Data Analyzer Module
