Embodiment Construction

[0019] The technical content of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] In the prior art, the synchronization process of the main and standby model data of the power SCADA system is mostly done manually, which cannot be guaranteed in terms of cost and safety. For this reason, the present invention proposes a method for realizing automatic synchronization of model data of the master and standby dispatching systems. see figure 1 In the logical frame diagram shown, data exchange is performed between the main dispatching system and multiple backup dispatching systems (hereinafter also referred to as master dispatching and standby dispatching) through the TCP / IP protocol.

[0021] Among them, the model data synchronization process in the calling system includes the following steps:

[0022] 1. When the model data of the main adjustment system is changed, record the operation s...

Abstract

The invention provides a main-standby scheduling model data synchronization method for an electricity SCADA (supervisory control and data acquisition) system. The method includes that (1), when model data are changed, a main scheduling system sends a model synchronization request to a standby scheduling system; (2), when detecting the model synchronization request, the standby scheduling system receives the model synchronization request of the main scheduling system; (3), the main scheduling system writes the model data into a server of the standby scheduling system and performs model synchronization process tracking; (4), the standby scheduling system feeds back synchronization information to the main scheduling system, and the main scheduling system writes the synchronization information into a log after tracking the synchronization information. The main-standby scheduling model data synchronization method has the advantages that automatic synchronization of the model data of the main scheduling system and the standby scheduling system is achieved, and the model data, generated and stored on the basis of definition and instantiation, of the main scheduling system can be safely synchronized to a model database of the standby scheduling system in real time, so that simplicity and convenience in user maintenance are improved, maintenance cost is reduced, and date security is enhanced.

Description

technical field [0001] The invention relates to a method for synchronizing the data of a main dispatching and a standby dispatching model of an electric power SCADA system, and belongs to the technical field of electric power system dispatching. Background technique [0002] In the specific application of the power SCADA system, the model data of the main dispatching system and the standby dispatching system are required to be consistent. Since the main and standby dispatching systems are SCADA systems distributed in different regions and running on different dispatching systems, there are certain difficulties in the synchronization of model data. At present, most of the model data synchronization of the master and backup systems is realized in the following two ways: each definition and instantiation, and storage device copying into the warehouse. This greatly increases the maintenance cost and the difficulty of cross-regional work, and cannot guarantee the consistency and...
