The research on synchronous generator real-time simulation using an embedded parallel system based on Ethernet

摘要

Using synchronous generator as a research object, this paper establishes a partition model for parallel simulation task according to the mathematical model and requirement of the simulation platform, which is an embedded parallel system based on Ethernet. Through optimizing communication protocols based on MAC layer, the data communication intervals between nodes in the parallel system are shortened largely. Based on the partition model, an optimization scheduling algorithm has been studied to map the parallel tasks to the various nodes in parallel system in order to balance dynamic loads of parallel nodes and get high parallel efficiency of the system. According to the evaluation results of the asynchronous generator simulations, this paper verifies the feasibility of real-time simulation based on the parallel system.
