提高变电站监控系统信号设置的合理性

随着220kV变电站无人值班改造后不断接入中心集控站，变电站监控系统信号设置的合理性问题不容忽视。对于南京地区220kV变电站监控信号的设置情况和存在问题进行了调查分析．结合现场运行的实际需求，针对各220kV变电站目前的不同情况提出了在变电站监控系统中合理设置监控信号的建议，并已逐步应用于改造工程中。

Improve signal setting rationality of substation supervisory control system

Along with the integration of 220 kV unattended substations into centralized control station,more attentions should be paid to the signal setting rationality of substation supervisory control system. The signal setting status of supervisory control systems in Nanjing area and the exis,ting problems are investigated and analyzed. According to the actual conditions of different 220 kV substations,some suggestions are put forward to rationalize the monitoring signal setting,which are applied in substation reconstruction projects.
