一种适合并行计算的仿真变电站一次系统模型

A Primary System Model of Simulation Substation Suitable for Parallel Computing

为降低仿真变电站建设成本、提高仿真变电站仿真质量,提出了一种适合并行计算的变电站一次系统模型。采用短路故障转移法减少仿真模型的节点数,采用贝瑞隆法使输电线路仿真模型与站内仿真模型相分离;采用异步替代法分裂站内仿真模型,且给出了选取重叠电路的原则。实例测试表明:基于贝瑞隆法和异步替代法建立的仿真模型适合并行计算,构建的数字式一次系统能很好地与真实二次设备相配合。

A new primary system model of simulation substation suitable for parallel computing is proposed in order to decrease equipment cost and enhance simulation quality of simulation substation. Several measures are adopted such as ： reduce nodes of simulation model by short circuit fault transfer, separate line model from substation equipment model by using Bergeron＇ s circuit, split the substation equipment model by asynchronous substitute and give selection principle of overlap circuit.Prototype tests show that the simulation model built on Bergeron＇ s circuit and asynchronous substitute suits for parallel computing, and the digital primary system may operate well with the real secondary devices.
