社会与经济的发展对电力的需求日益增加,同时对电力系统的安全稳定性也提出了更高的要求。结合先进的计算机和通信技术,提出了新型的电力系统暂态稳定评估方法。通过基于PC机群的并行化程序设计技术,某区域电网实际系统的仿真算例表明该方法能够取得比较理想的加速比和并行效率,具有广阔的工程应用前景。
With the development of society and economy, the demand of power is increasing and its system security and stability become the key issue. This paper proposes a novel method for transient stability assessment of power system, which combines advanced computer and communication technology. By the parallel technology based on PC cluster, the simulation case of one regional power grid demonstrates that the method can get ideal speed-up and parallel efficiency, which owns broad foreground in projects.
