Problems solved by technology

[0004] However, since the distributed parallel real-time library provides services for many different applications, the real-time database of each application switches frequently, how to correctly locate the current host node of the application is an urgent problem to be solved by the parallel real-time library
If the information of the main and standby machines is not timely and not the latest data, then the application cannot obtain the latest data and cannot complete further calculations

Embodiment Construction

[0029] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0030] In order to meet different application characteristics, the active / standby switching of the real-time library is very frequent. How does the application determine which is the main machine and which is the standby machine. The invention proposes a set of node positioning system, on the basis of ensuring high concurrent response of the parallel real-time library, correctly locates the host computer, and meets the requirements of application services. Before the client accesses the host, it first visits the Locator (location server) of each domain in the power system, then updates the host information of the machine, and finally obtains data from the host.

Abstract

The present invention relates to an electric power system control technique, and particularly to a parallel real-time database node locating system for a large power grid. The system comprises a client module for accessing a parallel real-time database host node module, the host node module returning host information and directly accessing a host; the host node module for receiving a request from the client module, accessing the locating server module, and returning the host information; and the locating server module is used for acquiring the host information about an application from a system management module. On the basis of guaranteeing a high concurrency response of a parallel real-time library, the host is accurately located, and requirements of application services are met. Before accessing a host, a client accesses a locating server of each domain in an electric power system first, then updates the host information about the host, and finally acquires data from the host.

Description

technical field [0001] The invention relates to power system control technology, in particular to a parallel real-time database node positioning system for large power grids. Background technique [0002] In the existing power dispatching technical support system, a real-time database is used to store and manage real-time data such as remote measurement and remote signaling. With the development of the power grid, the amount of real-time measurement data continues to increase, and the efficiency and storage bottlenecks of the real-time database used in the existing dispatch automation system are becoming more and more significant. [0003] In order to solve the above problems, the distributed parallel real-time library came into being. The distributed parallel real-time database is composed of multiple nodes, which provide services at the same time and provide very powerful support for high concurrent access. [0004] However, since the distributed parallel real-time libra...
