摘　　要：针对现有的智能变电站仿真试验系统无法良好应用于变电站现场等问题,提出了一种基于无线数据通信的智能站二次设备集成测试方案,并研发了系统软硬件。该系统采用电磁暂态计算获取整站正常运行及间隔典型故障的电流电压值,通过专用的亚毫秒级高速同步无线数据通道将试验数据发送到各被测间隔,并开发分布式数据终端实现仿真测试系统与变电站二次系统的无缝连接,完成二次系统不同范围、不同功能的重点测试。通过实际变电站的模型搭建及故障仿真测试,验证了该测试系统的有效性。In view of the problem that the current smart substation simulation system can not be well applied in trans- former substation, a novel integrated testing method for secondary equipment based on wireless data communication is proposed, meanwhile, .the hardware and software of testing system are developed. In this system, electromagnetic transient calculation is adopted to get the current and voltage value of substation normal running or malfunction, which is transferred to the tested substation interval by special sub-millisecond wireless channel, and some distributed termi- nals are designed to realize the seamless connection between the simulation system and substation secondary system. This system can realize the integrated testing of different functions of secondary system in smart substation, and the ef- fectiveness of the testing system is proved by substation model founding and fault simulation.
