Hardware Platform Design for Network Performance Closed-Loop Testing System of Smart Substations

This paper analyzed the development status of domestic network performance test systems for smart substations, and then proposed a network performance closed-loop test system based on IEC61850, which can be used for smart substations. This system can be uniformly applied to carry out carry out the function verification and performance evaluation test of all secondary devices, networks, switches, merge cells, smart/ terminals, protections, monitoring, measurement and recording equipment. It has good portability and can be easily used. Here the building of hardware platform for this system is expounded.

Development of Integrated Design and Management Tool of Intelligent Substation

The design, configuration, operation and maintenance of configuration files in intelligent substation are currently still utilizing the models for secondary system of regular substation. The disadvantages, such as the separation of design and configuration and the lack of control means in configuration files, make the configuration files in the fade zone of operators. Therefore, we developed an integrated configuration and management tool based on graphic-model integrative and version check technology. The visualization, synchronization, and hierarchical change indication of configuration were realized in the Auto CAD platform. This research provided an efficient strategy for the design, operation and maintenance of configuration files in intelligent substation.
