ELECTRIC POWER SUPERVISION

摘要

The present invention utilises direct measurement of marginal critical quantities in direct connection to interesting points in electric power processes in the different electric power objects (10, 12, 14). These points are generally located at places difficult to access, such as on high potential, or at rotating parts (17). The measurements give direct information about actual, now valid operational margins, concerning marginal critical quantities and in particular for quantities that is both marginal critical and material critical. Data about available margins is transferred to other units (32) within the network or plant (1). The electric power plant (1) or electric power network can then be controlled based from such actual operational margins from several different units (10, 12, 14) in the plant (1), which enables a more efficient operation of the plant (1) or network. The measurements give further new paths for detecting faults in the systems. Furthermore, databases of operational conditions can be built, which then can be used both as support for the operation of the system as well as for future maintenance, model building etc.
