Typically located on a large compound and comprise ofvarious facilities, steel-working plants consume largeamount of supplies and services
The plant processing is sub-divided into the categoriesof Iron Making, Steel Making, and Rolling
A Steel plant is configured from tens of different types ofequipments, each of which is controlled independentlyby a control system.

New system can be added with the existing system, Thus,values initial implementation costCentralized Monitoring of entire system will reduce resourcecost as well as speed up decision making
Allow operators, engineers, and managers to make betterand more informed decisions in the critical aspects of theirbusiness
Advanced Monitoring provides intuitive, intelligent, and
integrated real-time monitoring via a state-of-the-art interfaceEnergy Accounting provides detailed energy consumptionand cost analysis. Reports are generated based on energytariffs and electrical power market exchange information.

Simulation capability (with entire network) is used forOperator Training as well in Critical Decision MakingSimulation of the plant will be ended up with many otheradvantages such as checking the equipment adequacy (e.g.circuit breakers and relay coordination), tuning the controlstrategy (e.g. SVCs tuning up according to the condition ofoperation), adjustments of the circuit protection (e.g. under-voltage and under-frequency relays setting), and many
others.The need for simulation also increase during thereinforcement when even a small scope change in a plant(such as adding a motor) must be carefully judged

Short-Term SavingsOptimal Supervisory ControlThis saving in energy cost is due to the overall systemoptimization and power loss reductions. Savings may beconsiderably for systems that have abnormal losses,circulation power, and/or energy cost penalties.Mid- to Long-Term SavingsOptimal Supervisory Control
This can be a major reduction in the equipment capitalizationcost by increasing equipment lifetime. This saving is achievedby continuously operating at a near-to-optimal condition andhence preventing possible overloads and under/over-voltagesituations.

Optimized load preservation The critical loads in a Steel Plant include Furnace and Mills.These machines are very large and are the backbone of the
entire process. Due to disturbances at the supply, if thesemachines are shed, it typically takes hours to bring them backin operation. ETAP ILS monitors the entire system collectivelyand knows the status of every individual load and the amountof loading. It uses this knowledge to reprioritize the load
shedding list dynamically such that all critical loads are beingpreserved under foreseen or unforeseen circumstances witha lot of commercial saving (saves on production, time andresource cost losses).

Eliminate unnecessary load sheddingProvides Commercial benefit by improving reliability andavailability of the process
Reduction of spinning reserve requirementsBy reducing the amount of required spinning reserve, thesavings on the fuel cost and maintenance for the dieselgenerators paid for ETAP ILS in the first year aloneFast response to electrical & mechanical disturbances< 100 ms from the detection of the disturbanceRobust calculation methodSimultaneous calculations and validated calculations reducefalse tripping and downtime of system

Operator alerts for marginal operating conditionsProvides Commercial benefit by providing vital informationabout the stability and availability of the system
Offline test and validation of load shedding response- Can test various scenarios upfront before deploying. Thus,improves reliability, decrease downtime, eliminate nuisancetripping, increase system availability- Open system, can add new possible disturbances and letthe program determine optimal shedable load and verifyresults. This reduces maintenance cost as well as enableoperator skill enhancement.
