Example Embodiment

[0033] Example 1:

[0034] Such as figure 1 As shown, a power grid dispatching control system includes several monitoring systems, multiple analysis decision centers built in different places, and application services run in the analysis decision center.

[0035] The monitoring system is connected or installed with a man-machine cloud terminal (ie man-machine operation interface). The man-machine cloud terminal communicates with the analysis and decision center through the client interface. Each analysis and decision center includes a set of servers for running application services and external interfaces The gateway node server cluster. On the whole, each analysis and decision center has application services that provide external services; for some specific application services, there is a main analysis and decision center that works.

[0036] The new generation scheduling control system includes two or more analysis and decision centers. In this embodiment, only two centers are sc...

Example Embodiment

[0037] Example 2:

[0038] A load distribution method based on scenarios and service status in a power grid dispatching control system business environment, including multiple analysis and decision centers, a certain analysis and decision center establishes a connection with the client, if it cannot be connected, it switches to the next analysis and decision The center until a certain analysis and decision center is successfully connected; the load distribution method includes the steps:

[0039] The successfully connected analysis and decision center responds to the designated service diversion location query request sent by the client, and then analyzes the decision center’s global scene information, global service information, and global center status information based on the query parameters and client location information in the query request , Get the address of the analysis and decision center of the designated business work, and send the address of the analysis and decision...

Example Embodiment

[0047] Example 3:

[0048] Such as figure 2 As shown, a load distribution method based on scenarios and service status in a multi-active environment of a power grid dispatching control system includes the steps:

[0049] Step 1. Configure the addresses and ports of several shunt decision centers on the human-machine cloud terminal; the addresses and ports are the virtual addresses and ports of the gateway server cluster;

[0050] Step 2. According to the display and operation requirements, the human-machine cloud terminal determines whether to locate and query the business by using the scene quadruple or the service name, and at the same time, according to the operating characteristics of the business application, give whether to locate the main work scene center of the business , And then call the client interface with these information (ie: scene quadruple, service name or main center) as query parameters;

[0051] Step 3. The client interface tries to connect to the diversion loca...

Abstract

The invention discloses a load shunting method and system based on a scene and a service state, and the system comprises a plurality of analysis decision centers, and a certain analysis decision center builds the connection with a client, and switches to the next center until the connection of a certain center succeeds if the connection cannot be achieved. The load shunting method comprises the following steps: in response to a specified service shunting positioning query request sent by a client, obtaining an analysis decision center address of specified service work according to query parameters and client position information in the query request and global scene information, global service information and center state information of the center, and sending the center address to the client; and in response to a specified service remote service calling instruction sent by the client according to the central address, accessing or calculating specified service data to realize load shunting. The realized load shunting can be carried out according to the scene and the service distribution condition. The method is suitable for all services of which centers provide peer-to-peer services, and also supports services of providing master/slave services.

Description

technical field [0001] The invention relates to a method and system for implementing load shunting based on scenarios and service states in a business multi-active environment of a power grid dispatching control system, and belongs to the technical field of electric power automation systems. · Background technique [0002] The new generation of power grid dispatching control system adopts the system architecture of "physical distribution and logical unity". strategy to further enhance the support capability of the power grid dispatching control system. The analysis and decision-making center realizes centralized analysis, optimization and decision-making. In order to ensure the stable and reliable operation of the system, the analysis and decision-making center carries out multi-point construction in different places and introduces multi-active technology. Multi-active means that multiple analysis and decision-making centers provide services to the outside world at the sam...
