Problems solved by technology

Under the traditional power quality monitoring platform, the storage capacity and computing power of the servers used are difficult to meet the increasing computing requirements. Although the purchase of higher configuration servers can temporarily meet the computing needs, it will bring more problems when there are no running tasks. big waste of resources

Abstract

The invention provides a method for monitoring harmonious waves in a power system based on a Hadoop platform. According to the method for monitoring the harmonious waves in the power system based on the Hadoop platform, efficient parallel processing of sampling data of monitored harmonic waves in a regional power grid is achieved by the construction of a Hadoop distributed file system and the design of a MapReduce parallel programming model. The Hadoop distributed file system and the MapReduce parallel programming model are adopted in the method so as to make full use of the powerful data storage capacity and computing ability provided by the Hadoop distributed file system and the parallel programming model, so that basic data of power quality monitoring in the regional power grid is stored and computed in parallel.

Description

technical field [0001] The present invention relates to the field of harmonic monitoring methods in power systems, and more specifically, to a method for monitoring harmonics in power systems based on a Hadoop platform. Background technique [0002] The proposal and development of the smart grid has correspondingly brought a large amount of investment in power quality monitoring terminals in the regional power grid of the power system. The increase in sampling frequency and monitoring time has accelerated the explosive growth of sampling data from the power quality monitoring platform of the power system. Under the traditional power quality monitoring platform, the data uploaded by the monitoring terminal is mostly processed in a centralized manner. With the continuous advancement of smart grid construction, higher requirements are put forward for the calculation speed and accuracy of power quality monitoring indicators. Under the traditional power quality monitoring platfo...
