摘　　要：针对110kV及以下规模的变电站自动化系统通信特点,分析了目前变电站内通信网络存在的不足。详细论述了VLAN技术的功能特点及其在变电站自动化系统组网中的传统应用,分析了VLAN技术在这种应用中的局限性。提出采用基于PVLAN技术的变电站自动化系统组网方案,解决了变电站自动化系统通信中的诸多隐患,有效地优化了通信网络。仿真实验和现场的实际运行充分验证了该方案的正确性与可行性。This paper introduces features of substation automation system communication of 110 kV and below, analyzes the shortcomings of current substation communication network. Firstly, the functions of the VLAN technology and its traditional application in substation automation system are described in detail. Then, the limitations of VLAN technology in this application are analyzed. Finally, a method for substation automation network based on the PVLAN technology is proposed which can be used to overcome the disadvantages, as well as effectively optimize the communication network of substation automation system. Simulation experiments and practical operation on spot verify the correctness and feasibility of this method fully.
