目前国内大规模新能源场站、县域规模万节点级电力系统等所需的仿真资源巨大，但实物仿真平台又存在造价高、编译速度缓慢、缺乏对其性能的关键指标的评价方法、关键仿真核心技术处于卡脖子等问题。鉴于此自主研制了一款新型国产实时仿真器UREP300，详细阐述了其组成原理及其并行迭代编译原理，并提出了仿真平台的关键指标以及评价方法，用以衡量仿真器性能优劣，且基于此与国外领先的实时仿真设备进行了详细对比。结果证明了UREP300在仿真领域的性能不亚于甚至超过了国外领先设备，尤其在编译速度方面实现了突破，极大缩短了编译的时间，解决了仿真平台缺失关键指标与评价方法的问题，为国产化研究进程做出贡献。

At present, there is a huge demand for simulation resources for large-scale new energy stations and county-level ten thousand nodes level power systems in China. However, physical simulation platforms have problems such as high cost, slow compilation speed, lack of evaluation methods for key performance indicators, and bottleneck in key simulation core technologies. In view of this, a new domestic real-time simulator UREP300 has been independently developed. Its composition principle and parallel iterative compilation principle are elaborated in detail, and key indicators and evaluation methods of the simulation platform are proposed to measure the performance of the simulator. Based on this, a detailed comparison is made with leading foreign real-time simulation equipment. The results have proven that the performance of UREP300 in the simulation field is comparable to or even exceeds that of leading foreign devices, especially in terms of compile speed, which has achieved breakthroughs, greatly shortened compilation time, solved the problem of missing key indicators and evaluation methods in simulation platforms, and contributed to the localization research process.
