Smart management system for power distribution unit areas

Abstract

The invention discloses a smart management system for power distribution unit areas. The smart management system comprises a data acquisition unit, a serial server, a monitoring management unit, and an alarming unit. The data acquisition unit is used for collecting voltage, current, power and power factors of each power distribution unit area and sending the voltage, current, power and power factors of each power distribution unit area to the serial server. The serial server is connected to the data acquisition unit, and is used for converting data received from the data acquisition unit into a TCP/IP protocol and sending the TCP/IP protocol to the monitoring management unit through an Internet or wireless network. The monitoring management unit is connected to the serial server, and is used for carrying out analysis of data received from the serial server and sending an alarm signal to the alarming unit when the data accords with preset conditions. The alarming unit is connected to the monitoring management unit and is used for sending an alarm when receiving the alarm signal. The power distribution unit area management efficiency is raised, and the power grid operation reliability is improved.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to an intelligent management system for a power distribution station. Background technique [0002] In recent years, the State Grid Corporation of China has proposed a development strategy to strengthen the construction of a strong smart grid and improve the level of grid intelligence, and put forward new and higher requirements for grid construction and management. In view of the current backward state of manual management of low-voltage distribution stations, the intelligent monitoring of low-voltage distribution stations has been researched and developed to realize scientific, effective and intelligent management of the stations. [0003] At present, in the management of low-voltage distribution stations, there is a lack of scientific and effective means to obtain basic data such as low-voltage line voltage, current, and residual current. On-the-spot measurement in the a...

AI Technical Summary

Problems solved by technology

[0003] At present, in the management of low-voltage distribution stations, there is a lack of scientific and effective means to obtain basic data such as low-voltage line voltage, current, and residual current. On-the-spot measurement in the area not only caused a waste of resources such as manpower and material resources, but also caused potential safety hazards to a certain extent.

Due to the inability to achieve real-time monitoring, there are problems such as untimely, incomplete and unscientific data acquisition in actual work, resulting in the lack of scientific and accurate effective data in the power supply company's online loss management, voltage management and power supply reliability management.

[0004] At the same time, for the power outage caused by the tripping and locking of the switch in the station area, the business office will not know until the user reports for repairs, and then send personnel to the scene to perform the switch closing operation. Most users will not call the power service hotline immediately after the power outage or The business office rushed to repair the on-duty phone, which also greatly reduced the reliability of power supply, thus affecting the safe and stable operation of the power grid and causing inevitable economic losses
