| Abstract: |
| Basic conditions for the sequential operation of substation are discussed,and a tech-nical plan is presented for substation automation system to realize cell operation at cell level and cross-cell operation at station control level.The safety mechanism in sequential operation process is analyzed,and the main criteria for ensuring operational safety are put forward.Suggestions are given for the sequential operation of whole substation,the change of protection operation mode during sequential operation and the restriction in communication protocol between substation and control centre.The intelligent HV electrical equipment and control system and the improvement of operation mode of substation are required for the development of electrical network. |
