Abstract

The invention discloses a power distribution network operation data monitoring system and method based on a synchronous vector. A line monitoring system is connected with an intermediate server; the intermediate server is connected with a monitoring background system; the line monitoring system comprises a monitoring module; a GPS synchronization module and a protection module are connected with the monitoring module; the monitoring module is connected with a control module; the monitoring module is connected with a collecting module; the collecting module is connected with a communication module; and the communication module is connected with the intermediate server. The technical problems that great inconvenience is brought to operation monitoring and operation maintenance of a power distribution network, and the like because the problem of delay caused by remote data transmission in the power distribution network, the problem of system performance reduction caused by low harmonic measurement accuracy and the problem of low positioning speed and precision of a single-phase earth fault cannot be well solved in the prior art are solved.

Description

technical field [0001] The invention belongs to distribution network monitoring technology, in particular to a synchronization vector-based distribution network operation data monitoring system and method. Background technique [0002] The distribution network is in the power distribution link of "generation-transmission-distribution-use", which involves complex and changeable grid structures, wide power supply areas, various types of equipment, and a huge amount of operating data. In the process of transitioning from the traditional distribution network to the smart grid, the real-time and accuracy requirements of operation data monitoring are getting higher and higher, but the existing distribution network data monitoring devices are facing the problems of poor real-time performance and single function, which seriously restricts Upgrading of distribution network. The delay problem caused by remote data transmission in the distribution network, the system performance degra...
