To improve the efficiency of the substation, one of the most fundamental way is to improve the automation level of management and operation of substation, integrated automation transformer substation. In this paper, according to the requirements of substation substation technology, from the current mainstream fully distributed structure of the overall layout and structure, were designed for a system and the two system. In the part of hardware selection of transformer with three-phase transformer, compared with transformer single-phase transformer group, lower cost, smaller footprint, operation cost less, greatly reducing the investment and operating costs. In the software configuration, the actual use of feedback of RCS-9000 substation integrated automation system is very good. Its characteristic is measuring, monitoring, control, protection and automatic operation function in a body, can satisfy the need for stable operation of the 35kv-500kv substation substation of different standards, provides reliable technical condition of transformer substation automation unattended operation management.
