摘 要： 为了提高实验室完成大规模稳控系统能力，设计了一种数字仿真仪远程测试数据转换系统，并展开实验测试分析。数据接口转换装置为各测试厂站都配备相应的模拟量控制参数以及开入量与故障选择参数，通过软件系统控制仿真设备与测试站的延迟参数。为了跟远程测试系统形成良好配合状态，构建一个具备标准化要求的远程测试模块。经仿真发现各项策略动作准确，系统满足稳定性要求，与传统形式的RTDS仿真过程相比，实现了高度一致的动作状态，不过完成整组动作需要增加62 ms左右。由于稳控系统执行站机组中断路器需要约50 ms的时间完成动作，远程测试情况更加符合现场稳控系统控制情况。

Abstract： In order to improve the ability of completing large-scale stability control system in laboratory， a remote test data conversion system of digital simulation instrument is designed， and experimental test and analysis are carried out. The data interface conversion device is equipped with corresponding analog control parameters and input and fault selection parameters for each test station， and the delay parameters of the simulation equipment and test station are controlled by the software system. In order to form a good cooperation with the remote test system， a remote test module with standardized requirements is constructed. After simulation， it is found that each strategy action is accurate and the system meets the requirements of stability. Compared with the traditional RTDS simulation process， it achieves a highly consistent action state， but the completion of the whole group of actions requires an increase of about 62 ms. Since it takes about 50 ms to complete the operation of the circuit breaker in the unit of the execution station of the stability control system， the remote test situation is more consistent with the control situation of the field stability control system.
