With the development of smart distribution networks, the access of distribution generation (DG) presented new challenges to the operation and protection of power systems. Based on the hierarchical and modular structural ideas, this paper constructs a centralized distribution network protection system structure with a split layered architecture. The system improves protection accuracy and reliability through split protection, and achieves independent configuration, flexibility, fault isolation, information exchange and scalability. At the same time, protection efficiency is improved through hierarchical protection, hierarchical configuration, coordinated operation and rapid recovery are achieved to optimize power supply reliability. Under different fault scenarios, split and layered distribution network centralized protection is used to analyze the interaction process of random loads and intermittent distributed power sources on the active distribution network. Simulation results show that the architecture is effective and correct.

Substation is a vital part of power system where all electrical equipments are installed for transformation of electrical power from one circuit to another circuit without changing its frequency. Now a day due to economical as well as technological growth the power transferring system is totally automatically. Yet it is not applied to almost all places but most of the substations in India are automated. Power utilities adopt SCADA system for maintenance development and operation. It provides an application program for acquiring real time data from IED/RTU using open process control technology for substation monitoring. Now a day modified substation is installed with LAN system and Ethernet, such substation is design for task which uses communication system. Due to increasing combined distributed energy resources such as small photovoltaic plants or micro-cogeneration system grid leads to new competition to distribution system operation (DSO'S). TEC has developed a global communication standard. IEC 61850 is to facilitate substation automation. Communication security and reliability become important and it should be considered to ensure correct operation of substation automation system. Hence to make all automated we are trying really hard from our project. Since Substation is manually operated. It required lots of skill manpower for successful operation and it also leads to many human errors. Hence we need to automate the substation. Risk and reliability analysis of substation auto system are the most important and desirable design considered.
