Embodiment

[0047] In this embodiment, a real-time database system based on SOA framework power dispatching system, such as figure 1 As shown, including a pre-unit 4, a user unit 1, a background processing unit 2, and a service unit 3 arranged on the cloud server based on the SOA framework, the user unit, the service unit, and the front-end unit are respectively connected to the background processing unit;

[0048] The front-end unit obtains the telemetry and telesignal data of each measuring point and sends them to the background processing unit;

[0049] The user unit is used to display the telemetry and telesignal data of each measuring point in the system to the substation in real time, form a file according to the editing of the data by the user, and update the display data after processing by the background processing unit;

[0050] The background processing unit receives the information of the front-end unit and the user unit, groups the data of each measurement point into differen...

Abstract

The invention relates to an SOA-based real-time database system for an electric power dispatch system and an implementing method. The system comprises a front unit, a user unit, a background processing unit, and a service unit, which are based on SOA and are arranged on a cloud server, wherein the user unit, the service unit and the front unit are connected with the background processing unit. By using the real-time database system, databases are virtualized and data are formed into unified public arrays as service providing access interfaces and the objective of accessing the databases can be achieved by means of invoking service, so that the problems of complicated installation, maintenance and interaction of commercial databases are avoided. The system has the advantages of lower cost, greater reliability, greater instantaneity, and greater extendibility.

Description

technical field [0001] The invention relates to the technical field of power grid dispatching, in particular to a low-cost, high-reliability, real-time real-time database system and an implementation method based on an SOA framework power dispatching system. Background technique [0002] The power dispatching automation system is a distributed, heterogeneous and complex integrated system for real-time monitoring. The real-time database management system is the core support platform of the SCADA system and the EMS system. Its real-time performance, reliability, stability and openness directly determine performance of the entire system. Applications such as data acquisition, data monitoring, and real-time alarms in the SCADA system need to reflect the operating status of the power system in real time, especially when the operating status of the power system changes, it is required to receive, record, alarm and process corresponding events in a short time. It requires frequent...
