Using object-oriented technologies to solve substation automation dilemma

Traditional substation automation/integration systems involve huge numbers of man-hours to commission and maintain, even for similar systems. Using object-oriented technologies can reduced this commissioning time by around 80%. This has been demonstrated by field experience. The real-time information processing objects are composed of interaction-GUI parameters, real-time data, and functional processing. The defined objects - classes can be re-used among all the projects. Commissioning a new project is just to create instances of classes by "drag and drop". No more individual point/tag definition or verification is needed. These steps were done once when class was created. Changes made to class changes all its instances automatically. The classes can be inherited from, referred to, and embedded into others classes. Simple naming convention makes data usage instances link to data source instances automatically.
