Abstract: Along with the application of computer science, communication and control (abbreviated as 3C) in distribution power network, information exchange among the physical components of distribution power network is substantially enhanced. Furthermore, its capability of perception, integration, coordination and autonomy is also strengthened. This kind of technology is named cyber physical system (CPS). This paper investigates the mechanism of the CPS of distribution power network from the perspective of cyber physical integration, so as to figure out the impact of diversified control modes and CPS configuration on the operational characteristics of the distribution power network. The theory of CPS is validated by analyzing three representative applications. In the analysis, three aspects, including the historical development, various demands and application situations, are taken into consideration.
