Distributed type electric power quality monitoring system

Abstract

The invention discloses a distributed type electric power quality monitoring system. The distributed type electric power quality monitoring system comprises a current sensor, a voltage sensor and the like. The scheme of combining a zigbee network with a 4G communication network is adopted, compared with an existing scheme of the pure zigbee network or an existing scheme of combining the zigbee network with a wired network, installation and arrangement are easier, and the requirement for the real-time performance and reliability in the data collection and transmission process is met; particularly, video bitstream transmission and current and voltage data transmission are achieved through the same zigbee network and a full-function device, and a plurality of simplified device nodes are arranged at all points.

Description

technical field [0001] The invention relates to the electrical field, in particular to a distributed power quality monitoring system. Background technique [0002] Power quality is the quality of power in the power system. In modern power systems, voltage sags, swells and short-term interruptions, and voltage waveform distortions generated by harmonics; have become the most important power quality issues. Therefore, the importance of the status of the power quality monitoring system is self-evident. [0003] The existing power quality monitoring system can only realize the dynamic analysis of the basic operating conditions of the power system, and carry out effective and real-time update measurement and data collection of various power quality indicators; Pollution is very serious, and sometimes it is prone to strong winds, rain, and man-made or animal bites. In this way, the existing power quality monitoring system cannot provide reliable data basis for improving power qu...

Problems solved by technology

[0003] The existing power quality monitoring system can only realize the dynamic analysis of the basic operating conditions of the power system, and carry out effective and real-time update measurement and data collection of various power quality indicators; Pollution is very serious, and sometimes it is prone to strong winds, rain, and man-made or animal bites. In this way, the existing power quality monitoring system cannot provide reliable data basis for improving power quality and controlling grid pollution. Passing on-site inspection is not only time-consuming and labor-intensive, but also not conducive to rapid on-site repairs

In addition, the homework training for newcomers in the future cannot enrich more actual cases

Moreover, the cables are densely distributed, installation and maintenance are difficult, and they are often affected by distance, so that the monitoring system cannot meet the requirements of real-time performance and stability.
