Abstract: Modern manufacturers of relay protection equipment and transient monitoring systems for power systems test the equipment being developed under conditions that are as close as possible or completely repeat the actual operating modes of the electrical network. Many manufacturers and research teams are actively developing approaches to reproducing the operating modes of real electrical network objects [1-3]. The most common way to recreate the real operating conditions of measuring systems, relay protection devices and automation systems is the use of the well-known Dommel cycle when constructing systems for simulating the operating mode of an electrical network in real time in RTDS [5-7]. This approach is implemented using specialized software. The operation of programs and optimized models of electrical network equipment is possible using, as a rule, industrial controllers [4] and is the optimal solution. However, the result of modeling unique signals that describe the electrical mode at the investigated equipment connection point is possible in the presence of devices for matching the model and the physical level of analog current and voltage signals. In this work, it is proposed to use OMICRON CMC-356 as a device for matching with the physical level of analog signals [8]. The authors have developed specialized software that makes it possible to match simulated signals in real time with the required levels of analog voltage and current signals. The solution proposed in the work allows synchronizing the generated signals according to data from the GPS global positioning system. The issues of generating model signals with different amplitudes, initial phases and specified rates of change of parameters have been solved.
