Abstract

Power grid in future will develop into an extra-large interconnected grid with larger transmission capacity and more complex running characteristics. The trend of grid dispatching control system must be global wide-area and dynamic integrated necessarily. In this situation, it makes higher demand for real-time data to support grid supervisory and analysis. However, the existing real-time database with a centralized architecture commonly had the limits of scalability and performance, and it could hardly support a large number of concurrent data access. This paper proposed an architecture design of wide-area distributed real-time database (WDRTDB). WDRTDB divided all the real-time data into parts, and stored them on several servers. In addition, WDRTDB introduced a novel kind of data dictionary to index all data to provide a unified data access service for whole grid. Through experiments, we proved that WDRTDB had a better performance in real-time data processing than existing real-time database system.
