Based on the problems of extra(ultra) high substation digitalization and smart grid

Optical digital substation protection equipment on-site debugging technology, Energy Measurement, Conformance Test Platform is the key for extra(ultra) high-voltage substation to digitize and achieve smart grid. Achieved with the optical sensor applications in research breakthroughs, IEC 61850 standards promulgated, so network communication technology and the development of intelligent circuit breaker, digital has become the mainstream of the development of substation automation technology. As the number of substations in the network communication is very complex, it is necessary to its products and systems for conformance testing of communication behavior. Testing three different devices is to ensure the interoperability. That interoperability for communications services is to obtain the basis for functional interoperability, and for functional testing and engineering applications more closely. For the future of Digital Optical transformer substation in the electric energy measurement and energy measurement of the difference between the traditional influence and the characteristics of the secondary circuit are introduced, and debug digital protection scheme, the entire group and network transmission time of the test methods and existing Some common problems and put forward his point of view.
