Abstract

The present invention discloses a low-voltage electric power network monitoring terminal and system. The terminal comprises a Rogowski coil current collector, an A / D conversion module, an effective value calculation module and a wireless communication module. The Rogowski coil current collector conducts the measured real-time current value to the effective value calculation module through the A / D conversion module, the effective value calculation module performs calculation to obtain a current effective value according to the real-time current value measured by the Rogowski coil current collector and transmits the current effective value to the communication network through the wireless communication module. The monitoring system performs synchronization of measurement data of a plurality of monitoring terminals to a data cloud platform. The present invention provides a platform monitoring system being suitable for low-voltage electric power network. The system is high in portability, and practical and convenient, and can perform automatic synchronization of the measured data to the data cloud platform so as to greatly simplify the field staff operation.

Description

technical field [0001] The invention relates to a data monitoring terminal and a monitoring system, in particular to a data monitoring terminal and a monitoring system suitable for a low-voltage power network. Background technique [0002] Power supply plays an important role in modern life. In recent years, with the development of science and technology and the improvement of production level, various power electronic devices have been widely used, especially the application of dynamic nonlinear loads, resulting in power system Reactive power with transient and impact characteristics in the power grid, voltage and current waveform distortion, three-phase unbalance, low voltage and other conditions in the power grid are becoming more and more serious. The "pollution" of electricity has seriously affected the normal operation of the power system and the stability of electrical equipment. [0003] In order to control the power quality problems of low-voltage power lines, it i...
