Hypersim在密集节点独立电力系统实时仿真中的应用

Application of Hypersim to Real-time Simulation of Dense Nodes Absolute Power Systems

多节点、密集结构是舰船独立电力系统的特有结构,对此类电力系统,目前还没有可行的实时仿真方法。该文通过讨论电力系统全数字实时仿真软件Hypersim的特性,提出了以Hypersim为平台,解决密集节点独立电力系统实时仿真问题的方案,即采用解耦元件将整个任务分解为若干子任务,各子任务由不同的CPU单元分开处理,彼此间交换数据,亦即将一个完整的数学描述矩阵分为小矩阵以提高运算速度。基于多节点、密集结构独立电力系统的经典模型,通过对其静态和动态过程的仿真结果与EMTP对比分析,论证了Hypersim全数字实时仿真系统的实时性、正确性及其应用于区域配电自动化的可行性,从而为该类系统的实时数字仿真提供了一个可资借鉴的途径。

At present, no method is applied in real - time simulation of dense nodes absolute power systems, The characteristics of the Hypersim power system real - time simulation software are discussed. The method, based on Hypersim, dealing with real - time simulation of dense nodes absolute power systems is pointed out. That is, dividing the whole task into some sub - tasks by using the decoupling elements and each sub - task is treated by different CPU units which exchange data each other. That also is, dividing the integrated mathematics describing matrix into little matrix to cut down simulation step. A simulation example verifies the correctness and real - time of this method, and verifies its feasibility of applying in regional automatic distribution, which provides a valid approach to the real - time simulation of this kind of power system.
