Problems solved by technology

[0004] Foreign commercial large databases (such as PI, Wonderware) have been basically monopolized by foreign manufacturers for a period of time in the past, which are expensive, costly to expand functions, and cannot provide personalized services
[0005] Large-scale relational databases (such as Oracle and SQL Server) can also store massive amounts of big data after certain configurations, but they have to face various problems such as inability to distribute deployment, storage compression, slow query, weak aggregation support, and unfriendly display. question

Abstract

The invention relates to the technical field of data processing. in particular to a power grid maximum load and heavy overload big data analysis method based on MapReduce aggregation calculation. Current (I) data collected every 5 minutes by a medium voltage 10kV feeder, the active power (P), reactive power (Q), power factor (Pf) and other data collected by the 10kV distribution transformer every15 minutes are used to make load analyses of data. Then, a result is acquired through heavy overload times and time accumulation analysis by real-time load such that staff in charge of planning gainsa better understanding of running condition of accounting equipment. The big data platform is used to calculate the number of 10kV feeders in the distribution network, the number of overloads or overloads of 10kV distribution transformers, and each overload or heavyload duration. Therefore, overload or heavyload data is accurately calculated such that staff can have a better understanding of running condition of accounting equipment. The power grid maximum load and heavy overload big data analysis method is highly relevant to solution of current prolems and investments.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a large data analysis method for power grid maximum load and heavy overload based on MapReduce aggregation calculation. Background technique [0002] Currently, each collection point of power grid equipment can generate multiple pieces of data per minute, and each piece of data has a time attribute. If there are 10,000 collection devices, about 0.7M of data will be generated per minute, and the amount of data in a day will be nearly 10G. The storage pressure brought about by this "data expansion" has become one of the pain points in the development of power informatization and digitalization . [0003] At present, the way people deal with the rapid growth of massive big data is either to use foreign commercial large databases or large relational databases, but there are various problems. [0004] Large foreign commercial databases (such as PI and Wonderware) have been b...
