Problems solved by technology

[0004] However, due to its cost, there are very few applications in the distribution network. At the 2014 IEEE PES GM annual meeting, the University of California, Berkeley proposed the idea of ​​uPMU, adding GPS synchronization function to the power quality detector to monitor the distribution network. and control, but because it can only be installed in the user terminal, and the topology of the distribution network is complex, it is difficult for uPMU to effectively monitor the distribution network
The domestic distribution network has "multiple points, long lines, and wide areas", and the cost of using PMU and FTU is huge. The existing synchronization vector measurement device for distribution network cannot realize effective monitoring

Abstract

The invention relates to a distribution network synchronous phasor measurement device, which comprises a shell, a to-be-detected wire, and a printed board Rogowski coil, an induction energy-taking magnetic core, an energy-taking power supply module and a data acquisition terminal module arranged in the shell. The front and back of the shell are correspondingly provided with wire holes to form a wire channel, the printed board Rogowski coil and the induction energy-taking magnetic core are arranged at the wire channel, theto-be-detected wire sequentially penetrates through a wire hole behind the shell, the printed board Rogowski coil, the induction energy-taking magnetic core and a wire hole in front of the shell, the induction energy-taking magnetic core is connected with the energy-taking power supply module, and the printed board Rogowski coil is connected with the data acquisition terminal module, and the energy-taking power supply module is connected with the data acquisition terminal module. Compared with the prior art, the device has the advantages of low cost, light weight, good detection effect and the like.

Description

technical field [0001] The invention relates to the field of distribution network monitoring, in particular to a distribution network synchronized phasor measuring device. Background technique [0002] As the last link of the power system, the power distribution system is directly responsible for the requirements of users in terms of power stability, safety, quality, and economy. With the increasing development of our country's economic level, the improvement of our people's living standards and the application of a large number of precision household appliances make users put forward higher requirements for the quality and reliability of power supply. [0003] Traditional anomaly detection is based on individual detection, and the monitoring data is no longer in the same time profile, so that the irrelevant relationship between data at each point is interrupted. For example, the harmonic monitoring device can only monitor the local harmonic situation, and cannot macroscopic...
