Background technique

At present, all monitoring and processing information systems of monitoring substations operate independently and independently. The existing problems are as follows: First, the access and debugging of the controlled station in the centralized control system is inconvenient. When a new centralized control station is established, it is necessary to Existing substations are added to the centralized control system as controlled stations. However, the lines of most substations are running, and the line cannot be debugged in the centralized control system. Only when the line is out of power or a special power outage plan is made, can it be debugged. This brings great inconvenience to the initial debugging work of the centralized control system.

Second, the daily maintenance of the centralized control system is inconvenient. For example, every time the substation increases the interval, it is necessary to add interval information in the background, add part of the interval information in the uploader, and then the maintenance personnel of the centralized control station will add the corresponding information in the centralized control system. There are too many modification links in this way, which increases the workload of maintenance personnel and the probability of errors.
