The invention discloses a service registration framework of a power grid dispatching automation system. The registration framework is a multistage registration center framework, and nodes in the power grid dispatching automation system include a system registration center, subnetwork registration centers and common working nodes; the system registration center is deployed in the whole framework, and is used for collecting registration information of each subnetwork, and crossing network segments to synchronize to all the other subnetwork registration centers; the subnetwork registration centers are configured in each subnetwork of each safety partition, and are used for collecting registration information in subnetwork and sending to the system registration center, receiving service information sent by the system registration center and then synchronizing the service information to each common working node in the subnetwork; and the common working nodes are provided with shared memory units used for storing registration service information. The invention also provides a service registration method of the power grid dispatching automation system. The service registration framework and the method of the power grid dispatching automation system can realize cross-subnetwork service registration and service positioning.
Description
technical field [0001] The invention relates to the field of electric power information technology, in particular to a service registration framework and method of a power grid dispatching automation system. Background technique [0002] The network architecture of the power grid dispatching automation system must meet the requirements of "security partition, network dedicated, horizontal isolation, and vertical authentication" in the "National Power Secondary System Safety Protection Overall Plan". The system network is divided according to the security zone I, II and III, and different professional application systems are deployed in each zone according to the level of security. Different network segments are used to divide each area, and the network segments are generally no longer distinguished among the various application systems in the area. Under this traditional network architecture, each security zone contains a service registration center, and services in the sec...
