Unified modeling method employing generalized measuring transverse correlation mode

The invention relates to a unified modeling method employing a generalized measuring transverse correlation mode. The unified modeling method is characterized by comprising the following steps of grid equipment modeling, secondary equipment modeling, primary equipment and secondary equipment correlation establishing, asset modeling, other-data abstract modeling, generalized measuring model establishing and meta-model defining, wherein secondary equipment modeling is conducted according to the IEC61850, and a PSR is used as the center of a generalized measuring model. The method is also applicable to unified modeling of an automated system of all related information in a power system. The method increases the software development efficiency and accuracy, shortens the development cycle and realizes power grid model unification, a complete data platform is provided, the flexible metadata mechanism is adopted, a multi-layer system framework for services is used, and therefore convenience is brought to electric power information resource sharing.
