Power quality monitoring device and monitoring method thereof

Abstract

The invention discloses an electric energy quality monitoring device and a monitoring method thereof. The device comprises data monitoring nodes, a central node, an electric energy quality monitoring center, and an iPad. The method comprises internet-of-things networking of the data monitoring nodes, the central node, the electric energy quality monitoring center and the iPad, and other steps. The beneficial effects are that the device uses the data monitoring nodes based on a digital wireless network so that the voltage of a power system can be dropped and raised temporarily and terminated for a short time; voltage waveform distortion caused by resonant waves and other vital electric energy quality problems can be detected in real time to ensure electricity usage requirements of residents and industry.

Description

technical field [0001] The invention belongs to the technical field of electric equipment monitoring. In particular, it relates to a power quality monitoring device and a monitoring method thereof. Background technique [0002] During the 12th Five-Year Plan period, the motherland's economy maintained a medium-to-high speed development, and the power supply load of the power grid is also increasing. In order to ensure the electricity demand of residents and industries, the power supply company must improve the power quality. Accidents caused by problems occur from time to time, resulting in the loss of human, material and financial resources. Therefore, it is very important to monitor the power quality accurately, quickly and in real time. However, since there are many terminals to be tested, and most of them are distributed in areas with harsh climate conditions, the location distribution is also relatively complicated, so the data monitoring nodes located at each terminal...

Problems solved by technology

However, since there are many terminals to be tested, and most of them are distributed in areas with harsh weather conditions, the location distribution is also relatively complicated, so the data monitoring nodes located at each terminal are very cumbersome to arrange, and the inherent data monitoring nodes of each terminal are often affected by Damaged or slightly moved by the surrounding environment, "traffic jam" occurs when transmitting signals, and the transmission is also very messy and disorderly, which greatly reduces the efficiency and the stability and accuracy of detection. For monitoring data and historical conditions, staff often It can only be viewed and retrieved in the monitoring center, and cannot be viewed and retrieved in the field or outside the monitoring center. Moreover, due to the limited hardware conditions of the iPad, it is basically impossible to directly call the local authentication system using the browser in the iPad , it is necessary to develop a special browser security plug-in
