Problems solved by technology

Especially the distribution network, the system is complex and huge, it will be more difficult to find and determine the fault source or pollution source
In addition, due to the regional management of the current power system distribution and distribution networks of industrial and mining enterprises, self-contained systems, and independent operation of terminal equipment, there is a lack of a unified and synchronous operation mechanism. Once a failure occurs, the distribution network of the existing technology The electrical management system cannot yet collect data with the time of fault occurrence, that is, fault data with a time scale, which makes it more difficult to analyze faults and eliminate them as soon as possible

Abstract

A power distribution monitoring and measuring device with time synchronization function, including an analog signal acquisition module, a switch signal acquisition module, a data storage module, a keyboard/display module, a management module, a GPS/Beidou time synchronization mode module, and an IEEE1588 network Time synchronization mode module, NTP/SNTP network time synchronization mode module, RTC+ power frequency time synchronization mode module, time message information time synchronization mode module; set time scale for sampling data by selecting one or several of them; The invention makes the measured data all have time scales, solves the technical defect of the prior art that the measured data has no time scales, provides convenience for time point section analysis of the power distribution system, and provides a more practical method for analyzing faults and eliminating faults as soon as possible The data makes it possible to quickly troubleshoot; the device has the characteristics of reasonable structure, convenient operation, accurate time scale setting, and online or portable use.

Description

technical field [0001] The invention relates to an automatic data collection and processing instrument of a power system, in particular to a power distribution monitoring and measuring device with a time synchronization function. Background technique [0002] With the development of the national economy and the improvement of people's living standards, the requirements for power quality of smart appliances, smart meters, and advanced industrial automation equipment continue to increase. Electric energy is different from other products. The generation, transmission, transformation, distribution and use are completed at the same time, and the equipment in each link is connected in a system. With the development of the economy, the power system is becoming larger and more complex. A fault somewhere in the power grid or serious power quality problems such as harmonic pollution may occur at any time. Finding and determining the source of the fault or pollution will become a new t...
