    • 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.
    • 本发明利用与不同电力对象(10,12,14)中的电力过程中的有趣点直接连接的边际临界量的直接测量。 这些点通常位于难以进入的位置,例如在高电位处或在旋转部分(17)处。 这些测量提供了关于边际关键数量的实际的,现在有效的运营利润的直接信息,特别是对于边际关键和关键材料的数量。 有关可用边距的数据将传输到网络或工厂(1)内的其他单元(32)。 然后可以基于工厂(1)中的几个不同单元(10,12,14)的实际操作余量来控制电厂(1)或电力网络,这使得工厂(1)的更有效的运行 )或网络。 这些测量为系统中的故障检测提供了进一步的新途径。 此外,可以建立运行状况数据库,然后将其用作系统运行的支持,以及将来的维护,模型构建等。
