A Power Data Acquisition System Based on Distributed Message Queue

Abstract

The invention discloses a power data collection system based on a distributed message queue, including several sub-station pre-acquisition modules arranged on the ground survey side, and a distributed message communication management module arranged on the provincial survey side and master station data integration Module: The pre-acquisition module of the substation actively requests the distributed message communication management module to collect information from the local city, and dynamically loads the collected file information to the local database, then communicates with the remote terminal of electric energy to obtain the time-sharing electric energy indication value of the gateway electric energy meter ;The distributed message communication management module performs publish / subscribe message queue service node cluster management and task load balancing support on the provincial dispatching side; the power data collected by the local dispatching side passes the publish / subscribe message provided by the distributed message communication management module The queue service cluster gathers at the provincial dispatching side; the data integration module puts the electricity data collected by the local dispatching side into the storage at the provincial dispatching side through the buffer queue cycle storage algorithm.

Description

technical field [0001] The invention relates to a power data collection system based on a distributed message queue. Background technique [0002] As the basic data source for power economic analysis, the electric energy acquisition system provides electric energy data support for the development of power grid enterprises' power purchase, power sale, line loss and other businesses, and realizes power purchase settlement and network loss calculation. The construction of modern companies requires power grid enterprises to further control operating costs and improve economic benefits, and "refined management" of line loss is an effective means to achieve "cost reduction and efficiency increase" for power grid enterprises. With the increasing sensitivity and attention of the upper management department to the main indicators of economic operation such as line loss, new requirements and challenges have been put forward for the processing capacity of the traditional power collecti...

Problems solved by technology

[0003] The collection mode of the traditional power collection system is mainly local, single area, and centralized collection. By downloading the meter, terminal and channel collection file information (parameters) of the power plant and substation gateway electric energy metering points to multiple front-end collection servers, The power data collection is realized by the front-end collection server, and the quasi-real-time data is directly written into the historical database regularly. Due to the limitation of processing capacity, there are problems such as the mismatch between the quasi-real-time data and the historical database transmission rate and the redundancy of the collected archive information.

Facing the requirement of line loss in the same period to connect a large number of gateway meter power data of the main network 35kV and above substations (including the central control power plant), the current collection system is bound to bear huge collection pressure, and it is difficult to meet the comprehensive and comprehensive power data collection.
