| Summary: | 碩士 === 國立中山大學 === 電機工程學系研究所 === 91 === Customer side automations including automatic metering reading and load interruption are parts of an overall distribution automations (DA). Fault detection isolation and service restoration are considered the most beneficial functions among various DA functions. Due to the extensive areas covered by the distribution network, it is difficult to gather all real-time information from the distribution network. In order to aid in the monitoring of the power delivery quality and detecting fault, an automatic reporting system based on a digital signal processor, a public telephone system and a database system is presented in this thesis. In this system when the sensor detects a low voltage or lose of power, an alarm call will be placed via the telephone network. It will also report the energy usage of customer on a regular base. The control center master then organizes all incoming data into a useful information and displays the locations as they occur. This system will be useful to monitor power at various levels of the distribution circuits.
