Abstract:

With the development of automatic scheduling system, the transverse integration and vertical through of stages of scheduling system is kept being enhanced. The requirements of sharing of model and data between stages became more and more. The conventional model, due to complicated sharing method and related to operation on commercial library, has the risk that affect the system model. The distributed realtime database migration technology based on multisource data was indicated. Which is high efficiency and fast, and effectively avoid risks mentioned above. Pros and cons of existing data migration method of power grid scheduling automatic system was analyzed. Relative key technology was introduced. The implementation of this technology on Guangdong Power Grid Corporation Center for Power Scheduling and Control OCS proved that this technology increased the model maintenance efficiency, ensured the safety, enhanced the integration of scheduling system, and provided technical support to provincial and local intelligent power grid construction.
