Embodiment Construction

[0021] The present invention will be further described below in conjunction with specific embodiment:

[0022] A power quality monitoring query method, comprising the following steps:

[0023] 001. Each data monitoring node collects the power quality indicators of the distributed power sources it monitors in real time, and sends the power quality indicators to the corresponding dump nodes on a regular basis;

[0024] 002. After receiving the communication signal of successful networking from the power quality monitoring center, the transfer node sends the received power quality index to the power quality monitoring center in response to the communication signal of the power quality monitoring center;

[0025] 003. The power quality monitoring center encrypts the historical data after saving the historical data. The staff can remotely decrypt the historical data stored in the power quality monitoring center through a laptop computer, and browse and view the historical data.

Abstract

The invention discloses a method for monitoring and querying power quality, which includes the steps of collecting in real time the power quality indicators of distributed power sources monitored by each data monitoring node, and regularly sending the power quality indicators to corresponding transfer nodes; the invention takes into account the query The security of both the terminal and the power quality monitoring center, when the data is dynamically expanded on a large scale, the system will not be stuck due to encryption and decryption. The data monitoring node can accurately obtain the exact time when the network signal arrives at a certain node in the network, and has good fault tolerance for the loss of received Ethernet frame signals from different signals, and improves and effectively improves the power consumption of distributed power sources. The real-time nature of quality monitoring can ensure data collection, transmission, and storage in a certain degree of extreme weather, improving the reliability of power supply.

Description

technical field [0001] The invention belongs to the technical field of electric equipment monitoring. In particular, the invention relates to a power quality monitoring and query method. Background technique [0002] Distributed power supply is a new energy-saving and environmentally friendly power generation device, but there are many grid-connected points of distributed power supply, and most of them are distributed in remote areas with harsh climate conditions, and the location distribution is relatively complicated, which poses a threat to data monitoring, especially signal transmission and safety belts. Great difficulty came. Contents of the invention [0003] The object of the present invention is to provide a method for monitoring and inquiring about power quality in order to overcome the above disadvantages. [0004] A power quality monitoring query method, comprising the following steps: [0005] 001. Each data monitoring node collects the power quality indicat...
