The standard has been supported by most mainstream manufacturers at home and abroad, and has become the only unified standard in the field of substation automation in the world. Therefore, it has been widely used in the online monitoring of leakage current intelligent electronic device communication.
随着基于IEC61850标准一次设备在线监测在智能变电站的推广和应用，作为智能变电站重要特点的智能高级应用如一次设备健康状态评估等功能也在逐步试点应用中。但即使利用实际的在线监测智能电子设备，也很难对一次设备的故障进行模拟，而且一般在实验室很难具备这种条件，这对于跟踪并发现高级应用的问题造成了很大的困难。另一种方法是使用通用IEC61850/MMS服务端仿真，手动产生遥测、遥信量来模拟在线监测智能电子设备的通信行为，但在线监测智能电子设备发出的各模拟量数据间，模拟量与遥信量数据是尤其内在的逻辑关系的，这种逻辑关系正是模拟一次设备故障的关键所在，通用IEC61850/MMS服务端仿真很难满足相应的要求。因此如何简单高 效地进行在线监测智能电子设备通信仿真模拟，对相关高级应用进行开发调试，以及在工程测试平台上进行验证是一个亟待解决的问题。With the promotion and application of online monitoring of primary equipment based on IEC61850 standard in intelligent substation, intelligent advanced applications such as primary equipment health assessment, which are important features of intelligent substation, are also gradually being applied in pilot applications. But even with the actual online monitoring of intelligent electronic devices, it is difficult to simulate the failure of a primary device, and it is generally difficult to have such conditions in the laboratory, which makes it difficult to track and discover problems of advanced applications.

However, online monitoring of analog data sent by intelligent electronic devices, analog and remote The signal data is especially intrinsic logical relationship.

Efficient online monitoring of intelligent electronic device communication simulation, development and debugging of related advanced applications, and verification on the engineering test platform is an urgent problem to be solved.
