Electric quantity data acquisition system based on distributed message queue

Abstract

The invention discloses an electric quantity data acquisition system based on a distributed message queue. The system comprises multiple substation front acquisition modules arranged at local dispatching sides, a distributed message communication management module arranged at a provincial dispatching side and a main station data integration module, wherein the local acquisition information is actively requested by the substation front acquisition modules from the distributed message communication management module and communicating with an electric energy remote terminal to acquire a time sharing electric energy value of a gateway electric energy meter after the acquisition archive information is dynamically loaded to a local database, the distributed message communication management module is used for carrying out cluster management of publishing / subscription message queue service nodes at the provincial dispatching side and task load balancing support, electric quantity data acquiredby each local dispatching side are gathered through publishing / subscription message queue service clusters provided by the distributed message communication management module at the provincial dispatching side, through a buffer queue cycle database input algorithm, the electric quantity data acquired by each local dispatching side are gathered and inputted at the provincial dispatching side by the data integration module.

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.
