Modeling and simulation of synchronous condenser based on digital twin

Abstract

With the continuous development of UHV DC transmission technology, the synchronous condenser has become an important supporting equipment in the DC transmission project, and its mechanism modeling and simulation have important practical significance. Based on the digital twin technology, this paper establishes a hybrid symbolic numerical model of synchronous condenser, which can realize model reuse and rapid deployment. First, it analyzes the basic characteristics of the synchronous condenser, and then proposes the digital twin model framework of this article. The digital twin model of the synchronous condenser is developed based on the Andes power system simulation tool. Finally, a simulation case is used to verify the digital twin model of the synchronous condenser. The experimental results show that the digital twin model can realize simulation operation and fault characteristic response simulation.
