Components HMI •HMIisaninterfacedisplaywherevariouspiecesofinformationobtained from the field is transmitted via communication with the station controller; various data and trends are displayed; obtained information is categorized into databases; equipment condition/status is diagnosed via diagnostic algorithms; equipment service life is forecast and monitoring schedules are proposed based on data analysis; malfunctioning areas are indicated during an accident; and solutions to eliminate failure are suggested. HMI is the state-of-the-art diagnostic solution that combines the latest computing and digital technologies. Station Controller (Main Unit) •Thestationcontrollerreceivesequipmentcondition-monitoringdatafrom the DAU (Data Acquisition Unit) which compiles raw data measured from the sensors installed in the field, and transmits the information to upper-tier HMI through the internal communications controller. » Offers system redundancy » Provides easy-to-use interface with other facilities, through multi-protocols •Thestationcontrollerconvertsandprocessesthedatacollectedfrom the communication controller and transmits them to upper-tier HMI. It also analyzes the control instructions from upper tiers and delivers them to lower-tier DAU. » Configures individual communication channels between lower-tier systems » Enables peer-to-peer communication between upper-tier and lower-tier systems, respectively, and allows self diagnosis » Controls communication error (critical data backup and restoration) » Connects to Ethernet (10/100 Mbps) and serial devices (RS-232/422/485) » Supports multi-protocols (e.g., DNP 3.0, Modbus, Modbus Tcp) » Allows system database downloading from upper-tier hosts » Offers system stability through redundancy » IEC 61850 Protocol is applicable ( ) DAU Local Unit •Basedondiagnosticalgorithmsoptimizedforthetransformer/GIS,DAU attains data from various sensors and delivers the information needed for alarm and diagnosis. » Adopts high-performance DSP chip and conducts high-speed real-time A/D conversion » Stores data for 24 hours during a communication failure » Capable of optic and serial (RS-232/422/485) communication » Detects problems and issues alarms in accordance with its internal algorithm » Capable of integration monitoring of various sensors is possible
