Problems solved by technology
[0004] The purpose of the present invention is to provide a method for realizing the normal dispatching and monitoring of prefectures and counties under the condition that the wide-area distributed prefectural and county regulation and control integrated systems of the power grid are paralleled, which solves the problem of decoupling of prefectures and counties under the jurisdiction of prefectures and counties. After the factory station loses monitoring and is juxtaposed, the information of the prefecture and county is inconsistent

Embodiment Construction
[0022] The present invention will be further described in detail below with reference to the drawings and specific embodiments.
[0023] The typical backbone network networking mode of the wide-area distribution area and county regulation and control integration system of the present invention is as follows: figure 1 As shown, in the prefectural and county backbone network frame, two cascaded three-layer switches are installed in each area of each prefecture and county, and the backbone network between prefectures and counties is formed into a double ring network structure or a double star network structure through the switches. Typical structure, based on these two typical structures, various hybrid network architectures can be derived to form a wide-area distribution and integrated system of county regulation. A loop-free spanning tree backbone network. Among them, the county adjustment includes a disaster preparedness county adjustment, such as figure 1 The county dispa...

The invention discloses a wide-area-distributed city / county scheduling and monitoring integrated system subarea disconnection / connection operation method. The method is specifically characterized by, to begin with, establishing a backbone network dual-network structure which has spanning tree characteristics and is suitable for wide-area-distributed city / county scheduling and monitoring integrated operation and supports disconnection / connection operation; with the above network architecture, network communication can still remain normal when no more than three faults occurs in a backbone network; when four faults occurs in the backbone network, a subarea network state recognition module triggers county scheduling to go into a disconnection state, thereby enabling multiple islands to finish monitor tasks independently and separately and guaranteeing city scheduling to be able to receive data of factories and stations governed by the county scheduling; and after one or multiple links in network links of the disconnection county scheduling return to normal, the subarea network state recognition module triggers the county scheduling to go into a subarea connection state, thereby enabling the county scheduling to go back to the integrated operation state again. The method helps to solve the problem of network reliability for city / county integrated wide-area operation, and provide guarantee for safe and stable operation of city / county smart power grid dispatching technology support system.
Description
technical field [0001] The invention belongs to the field of electric power dispatching automation system, and especially refers to a method for splitting and parallel operation of a wide-area distributed district and county regulation and control integrated system, which is used for power grid wide-area distributed district and county regulation and control integration system under various network failure conditions Reliable and stable operation. Background technique [0002] The "big operation" with "intensification, flattening, and specialization" as the main line requires comprehensive coordination and coordination of dispatching at all levels. The wide-area distributed prefectural and county regulation integration system realizes the optimal allocation of prefectural and county resources through integrated operation, integrated maintenance, and integrated application, which is well adapted to the needs of prefectural and county-level smart grid dispatch automation const...
