苏州500kV变电站无人值守模式可行性探析

Feasibility of operation and management modes for 500 kV unattended substations in Suzhou

介绍了苏州500 kV电网的现状,从变电站设备缺陷、跳闸事故处理和工作量等方面指出500 kV无人值守变电站设计应该考虑运行管理模式改革和变电运行实际工作的需要。分析了影响苏州500 kV变电站实行无人值守或少人值守运行模式的各个要素,提出了无人值守变电站需要具备的条件。

The status quo of Suzhou 500 kV grids is presented. Based on the analysis of the substation equipment defects, the trip treatment, and the substation work load, it is pointed out that the operation and management mode changes and requirements of actual substation operation should be considered in design of the 500 kV unattended substation. Factors influencing the implementation of unattended or less-attended operational modes for Suzhou 500 kV substations are analyzed, and the conditions that the unattended substation should have are proposed.
