The modeling of self-healing control system for distribution network based on UML

Self-healing for smart distribution network which is based on Distribution Automation(DA) and Advanced Distribution Automation (ADA), is one of the key characters and core functions for smart distribution network to deal with the inside and outside threatens of the network as well as to increase system operation security and efficiency. In this paper, we focus on the modeling of self-healing control system for distribution network based on UML. Firstly, the background, application scenarios and requirements for self-healing control system of smart distribution network were analyzed. Then, the static and dynamic models of the control system were built based on UML. Three types of self-healing control are realized through four self-healing stages in three scenarios. Finally, based on the modeling results, the system architecture and key applications for the self-healing control system were implemented. The results in this paper are useful for investigation on the conceptions and key technologies, increasing the normalization and reusability of self-healing control system as well as guidance for real self-healing applications.
