This article introduces the development and simulation service mode of China's power system, and explores the feasibility and necessity of parallel simulation application of electromagnetic transient. The construction goals of a large-scale electromagnetic transient task scheduling platform were elaborated, and the platform architecture was compared with the current situation of the supercomputing center based on the online security analysis distributed parallel computing platform. We have conducted research on key technologies such as the construction and control of a unified resource pool on the platform, and the partitioning and distributed task scheduling mechanism. Based on the technical research, we have constructed a platform and verified the accuracy of parallel computing results on the platform.
With the expansion of power system scale and the increase of complexity, electromagnetic transient simulation plays a more and more important role in power system analysis. However, traditional simulation methods face the problems of large amount of calculation and long-time consumption, which is difficult to meet the needs of rapid analysis and decisionmaking of modern power systems. At the same time, the working mode of many people in different places requires that the platform can realize real-time data sharing and exchange. In order to solve this problem, this paper proposes and implements a distributed platform for cooperative calculation and simulation results management of electromagnetic transients. The platform uses multi-client collaborative computing technology to achieve efficient calculation of largescale electromagnetic transient simulation. At the same time, through the collaborative sharing and management mechanism, the cloud browsing, displaying and publishing functions of electromagnetic transient models, graphs and results for multi-users are realized, which can promote efficient communication of projects. This paper first introduces the overall architecture and key technologies of the platform, and then describes the implementation process of the platform in detail, including task division, data synchronization, collaborative computing and result management. Finally, the feasibility and superiority of the platform are verified by experiments.
