Using an integrated system, the transmission and distribution operators both see the same information- tags only need to be applied or removed once. This reduces the amount of paperwork operators need to complete, increases accountability and improves the tracking of safety documents. Of course, the real benefit lies in the utility's ability to provide more timely and accurate information tcMooancnvuaesgrt goe emmneecrnest . oSAf nDoi tsht er i rb ue txi oa nm pMl ea noafg i en mt e eg nr at t wi o i nt h i sOtuhtea g e ystems.

Distribution operators can also use network calculations to avoid accidentally overloading a given line while trying to supply customers from an alternate source. Today, the seamless integration of DMS and OMS functions is a reality, providing operators with a single intuitive interface to navigate between them.

The Sydkraft project, dubbed "Eldorado", replaced 20 SCADA systems and multiple geographic mapping systems with a single platform. The resulting cost "Depressed revenue streams, regulatory uncertai nty and competing investment alternatives have all conspired to make uti lity resources scarcer than ever, and as a result all departments are being asked to do more with less." savings are significant in terms of reduced redundancy alone. The reasons these utilities sought out an integrated solution mirror the drivers identified above: better coordination between transmission-and distribution- level operations, better customer service, and improved efficiency. These dobisjtericbtiuvteiosnwciollnctoronltisnue the trend toward unified transmission and ystems, particularly for larger utilities with more complex networks.

Blackouts are not good for anyone. Modern utility control systems like Network Manager offer an unprecedented array of tools with which grid operators are able to identify, avoid or mitigate disturbances before they become widespread outages. However, limitations remain. The next frontier in power systems monitoring and control is a group of technologies that collectively are known as Wide Area Monitoring Systems (WAMS).

These readings are then sent to a central control ystem which runs continuous online grid security assessments.
