The invention discloses a service registration framework of a power grid dispatching automation system. The registration structure is a multi-level registration center structure, and nodes in the power grid dispatching automation system are divided into a system registration center, a subnetwork registration center and ordinary working nodes; wherein , the system registration center is deployed globally to collect the registration information of each subnet and synchronize to all other subnet registration centers across network segments; the subnet registration center is configured in each subnet of each security zone , for collecting the registration information in the subnet and sending it to the system registration center, receiving the service information sent by the system registration center at the same time, and then synchronizing the service information to each common working node in the subnet; Common working nodes are provided with a shared memory unit to store registration service information. The invention also provides a service registration method of the power grid dispatching automation system. The invention can realize service registration and service location across subnets.
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...
