DMEX - Display and Expert System for Operators DMEX is an extension of MAVIR WebUI system. It supports the operators daily work as it gives an overview of the Hungarian grid based on a true-to-scale map of Hungary. Essential information of the transmission network is displayed on the map e.g.: MW overload percentage represented by cross border lines Overload of transmission lines of the distribution network (120kV) and basic network (220kV, 400kV, 750kV) Node voltage of substations Breakers overload of short circuit calculation Overload of network elements calculated by security analysis (N-1) Due to the applied data acquisition strategy DMEX supplies on-line information from Spectrum SCADA system and from the state estimators. The graphical representation of a cross border or transmission line reflects the overload percentage of the item using coloring and size encodings. Hence the color and the size of e.g. transmission line are dynamically changed in accordance with its overload. AMBer - Astron Messages Broker Astron Message Broker (AMBer) System is an Oracle based inter-application communication and archiving system. Designed for high-availability, mission critical operation. AMBer applies data warehousing technology to integrate, interface, publish and archive data coming from different IT systems. Located in the middle of a star schema, AMBer provides asynchronous or synchronous information exchange between heterogeneous systems. What makes AMBer different from common message-queueing systems is its ability to syntactically and semantically analyse the incoming data and store it in its own database. The data are converted and stored in a common, integrated form as well. AMBers unique internal database structure enables a simple and fast data conversion to any communication protocol format the client systems may need.
