摘　　要：有源配电网是智能电网中集成、管理分布式发电及储能设备、需求侧响应资源的重要平台,包括各种智能终端、控制及保护装置的研发与测试将对实时仿真提出更高要求。考虑有源配电网实时仿真的建模需求,文中基于实时仿真平台RTDS完成了含光伏、燃料电池等分布式电源的有源配电网暂态实时仿真建模,并给出了电力电子装置、分布式电源及控制器等特殊模型的实时仿真算法。研究了有源配电网在环境条件变化、系统故障及功率指令变化等各种场景下的动态过程,通过与离线仿真软件PSCAD/EMTDC的对比,验证了实时仿真模型的正确性,对系统资源消耗等分析,更为后续硬件在回路仿真(HIL)等研究中奠定了基础。Active distribution network （ADN） provides an important platform for integrating and managing distributed generators, energy storage equipment and the demand side response resources in smart grid. However, the R＆D and testing of intelligent terminals, control and protection devices give rise to higher requirements for real-time simulation. Considering the demands of ADN demands in real-time simulation, this paper completes real-time modeling and simu- lation of active distribution system with P~ and fuel cells based on RTDS. Real-time simulation algorithms for power electronic devices, DGs, controllers are introduced respectively. The transient characteristics of a benchmark case are analyzed under the condition of fault and environmental variation. The simulation results are compared with PSCAD/ EMTDC to validate the correctness and effectiveness of the model. The work lays a foundation for the future work on hardware-in-loop（ HIL ） simulation.
