MONITERING RF POWER SYSTEM IN GLOBAL ENERGY MANAGEMENT SYSTEM

摘要

A system for monitoring RF power in a global energy management system is provided to stably supply and use electricity and improve reliability of a product by calculating control data and performing measurement through complete Fuzzy automation of analog measuring equipment. A digital power measuring controller(11) is installed inside a power receiving and distributing board and performs element measurement, on and off of a circuit breaker, temperature control of a panel and a transformer, peak and power factor control, meter pulse input, and interface communication. An electric leakage alarm(12) performs leakage current measurement, plural contact output, multi-step alarm setting, alarm generation time, leakage current measuring, alarm reset by communication, and relay control output in case of generation of an event, and interface communication. An input and output relay unit(13) performs functions such as input state monitoring of a plurality of channels, setting by channels, and on and off control of an input relay unit and the plurality of channels to be interlocked with an output relay and the interface communication. A waveform capturer(14) performs present waveform measurement, fault waveform measurement, fault kind measurement, and interface communication. A sensor unit(15) senses signals corresponding to a fire index, a power condition index, an output attenuation index, a line quality index, and a comprehensive quality index. A main controller stores and manages all information for a system operation. A digital graphic system(17) performs power management by realizing information visualization of scattered large information in digital graphic technique and driving and operating in a touch screen through the integration of display units of measuring equipment. A power quality analysis system(PC) stores, analyzes, and manages all information for stable driving by analyzing various information measured by the measuring equipment and power quality related information.
