Intelligent management system at power distribution unit area

Abstract

The invention discloses an intelligent management system at a power distribution unit area. The system comprises a data acquiring terminal, a communication system and a background master control system, wherein the data acquiring terminal is used for acquiringthe voltage, the current, the residual current and the fault information at the power distribution unit area field; the communication system is used for transmitting the data; and the background master control system is used for monitoring a running condition of the power distribution unit area in real time, and remotely operating the power distribution unit area.The system disclosed by the invention realizes the distribution transformation and power utilization information monitoring of a user, has basic functions of voltage qualified rate statistic and line loss analysis management, and is capable of selectively configuring capacitor automaticswitching, three-phase imbalance adjustment and distribution transformation status monitoring functions; the voltage, the current, the residual current and other basic data of a low-voltage line can be acquired in real time; the acquired unit area running status data is more accurate and reliable, so that a power supply company possesses scientific and accurate valid data in the line loss management, the voltage management, the power supply reliability management and other work.

Description

technical field [0001] The invention relates to an intelligent management system of a power distribution station area, which belongs to the technical field of comprehensive electric power monitoring in the electric power industry. 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, curre...

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.
