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 power quality monitoring and querying method. The method comprises the following steps: collecting, by data monitoring nodes, power quality indicators of respectively monitored distributed power sources in real time, and periodically sending the power quality indicators to corresponding transfer nodes. By adoption of the power quality monitoring and querying method disclosed by the invention, the security of a query end and a power quality monitoring center is both considered, and during large-scale dynamic expansion of data, system stagnation is generated by encryption and decryption. The data monitoring node can accurately obtain the accurate time when a network signal reaches a certain node in the network, has better fault tolerance for the loss condition of received Ethernet frame signals from different signals, improves and effectively optimizes the real-time performance of power quality monitoring of the distributed power sources, can ensure the data collection, transmission and storage in a certain degree of extreme weather, and improves 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...
