35. ABB bv - 35  The total accumulated switched-off shortcurrents by a circuitbreaker or the number of generator starts are a trigger for maintenance No need for big oversizing of primary equipment In case of a shortage of electrical power, secure the available power to critical loads by switching off the none important loads according to dynamic load tables Optimizing the stability of the operation of the electrical generation- and distribution network of an industry Limiting electrical import during peak time and decreasing peak base chargeMaintaining a good Power Factor The Human Machine Interfaces for all the electrical sub-systems can be integrated in the Energy Management System Serial interfaces with protection & control units avoid spaghetti wiring & cable ducts Power Control, Standby Optimization, n+1 Criteria, SCADA, etc. are performed by the system and not anymore by the operators And thus ABB Power EMS helps you to: Avoiding black-outs (up to 500 kUSD / hour) Power Control including voltage control, frequency control, sharing power among generators and tie-line(s).
