Embodiment Construction

[0018] like figure 1 As shown, a substation DC system capable of remote operation and maintenance includes a DC panel 1 and a battery pack 2 arranged on the DC panel 1. The battery pack 2 is connected to a charging device 3, and the battery pack 2 is connected to a charger 4. It also includes a PC 5 and a monitoring system. The monitoring system includes a central processing unit 6 and a monitor 7. The central processing unit 6 is connected to the monitor 7, the charging device 3 and the charger 4 respectively. The monitor 7 is used for charging the battery pack and The computer is used for real-time monitoring, and the central processing unit is used to receive and analyze the monitoring data of the monitor. The PC 5 is connected with a database server 8 for judging the state of the DC system, and the PC is connected to the central processing unit for comparison between the monitoring data and the database server. Judgment and control instructions issued to the central proces...

Abstract

The invention relates to a transformer-substation direct current system capable of being remotely operated. The system comprises a direct current cabinet, a PC and a monitoring system. The monitoring system comprises a central processor and a monitor. The monitor is used for monitoring a storage battery group and a charger in real time. The central processor is used for receiving and analyzing monitored data of the monitor. The PC is connected to the central processor and issues a control instruction to the central processor. The system has advantages that the monitor monitors the storage battery group and the charger in real time and the central processor receives and analyzes the monitored data so that the direct current system can be monitored for 24 hours and the monitored data is compared and analyzed; once there is a hidden trouble which may cause an accident, according to a consequence of the accident which may be generated, an early warning grade is automatically analyzed and early warning is performed; and according to the determined early warning grade and prompt information, operation-maintenance personnel is notified, and the operation-maintenance personnel can carry out rapid pertinence processing on a problem according to the prompt information.

Description

technical field [0001] The invention relates to a substation DC system capable of remote operation and maintenance. Background technique [0002] At present, the DC system of the substation is an important power source of the substation, which is of great significance to the safe operation of the substation. After most substations are unattended, the monitoring information of the DC system is generally connected to the comprehensive automation background system. Because the collected data is not comprehensive enough, it is difficult for the maintenance management personnel to know the operating status of the DC system, and it is impossible to fully understand the status of the DC system and predict its changes. Trend conditions, even after the accident did not know that there is a problem with the DC system, which brings a huge safety hazard. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a substation direct cu...
