[0002] The current power automation real-time monitoring system generally adopts a single field system architecture. All nodes in the system form a single cluster. The number of nodes in the system is usually close to hundreds of units. Using a single field operation mode, each node needs to deploy a database. It is necessary to establish two-two full connections. The wiring of each node in the entire power automation system is very large and complex, and the slight jitter of the network will have a serious impact on the normal operation of the system; the cross-regional power automation system uses a wide area network for communication. In the system, regional nodes and The physical distance between county-level nodes may be hundreds of kilometers apart. In this WAN configuration mode, the network status is greatly unstable compared with the LAN network status. The real-time monitoring system relies on UDP heartbeat, and the node status information is reported synchronously. The network packets that maintain the normal operation of the system, such as documents, are prone to packet loss, which affects the normal operation of the system.

Embodiment Construction
[0018] The present invention will be described in further detail below in conjunction with the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.
[0019] Such as figure 1 As shown, it is a schematic flow chart of the database connection method of the cross-regional electric power automation system in an embodiment of the present invention, including the following steps:
[0020] S11. Obtain the network topology of the power automation system to be established, and read all nodes in the network topology;
[0021] First of all, it is necessary to obtain all the nodes contained in the power automation system to be established, and then read all the nodes in the network topology by obtaining its network topology. Each node is a power station; for example, a municipal power automation system, the municipal power The automation system includes multiple power stations covering the whole city, so the station network structure...

The present invention provides a database network connection method for a cross-regional power automation system, comprising: obtaining the network topology of the power automation system to be established, reading all nodes in the network topology; dividing the nodes into For multiple sites, deploy the database on at least one node in each site; connect a node without a deployed database in each site to one of the nodes with a deployed database in each site, and connect each node with a deployed database in each site Mutual connection; connecting one of the deployed database nodes in each site with one of the deployed database nodes in another site to form the database network of the electric automation system. Correspondingly, the present invention also provides a cross-region electric power automation system and a database network connection system thereof. The invention can effectively reduce the number of databases deployed in the system, significantly reduce the connections between nodes, and have high system stability.
Description
technical field [0001] The invention relates to a power automation system, in particular to a cross-region power automation system, a database connection method for a cross-region power automation system, and a database connection system for a cross-region power automation system.
