Abstract: today, the use of simulators is widely used in many fields, especially in the field of education. Being able to distinguish their preferred architectures, and choosing the type of simulation that is suitable and specific for each environment is considered to be an essential issue in preparing simulations. In addition to considering the types of simulators, this article also shows the most preferred types. Questions simulations were evaluated using the expert evaluation method.
Keywords: simulation, efficient, expert evaluation, live simulation, virtual simulation, virtual reality, non-immersive, semi-immersive, fully immersive, radar chart.

Аннотация: использование учебных симуляторов широко применяется во многих сферах, особенно в сфере образования. Способность различать предпочтительные архитектуры и выбирать тип моделирования, который подходит и специфичен для каждой среды, считается важной проблемой при подготовке моделирования. В этой статье также показаны наиболее предпочтительные виды симуляторов. Вопросы эффективности симуляции оценивались методом экспертной оценки. Ключевые слова: имитационное моделирование, эффективно ^ь, экспертная оценка, виртуальное моделирование, конструктивное моделирование, виртуальная реальность, неиммерсивное, полуиммерсивное, полное иммерсивное, радиолокационная диаграмма.
Consolidation of theoretical knowledge is, of course, inextricably linked with its application in a practical situation at the same time. But for students or personnel who do not have a certain category of technical safety, the implementation of theoretical skills directly in the workplace will cause the following inconveniences and dangerous situations: 1. Difficulty in explaining certain situations to the tutor. 2.Noise. 3.Carrying out tests at high voltages is dangerous to life.
Inability to demonstrate practices that must be performed at high altitudes.
Today, the use of educational simulators is highly effective as a solution to this. There are three (3) types of simulations commonly used [1]: live: A simulation with real people working in real time, individuals or groups are involved, can use real equipment, it should provide a similar field of activity, it should be close to replicating the actual activity.
Constructive

Virtual: Performed in a virtual state through people management: motor control skills (eg., flying an aeroplane), decision-making skills (eg, directing fire control resources into action).
Constructive: A simulation involving simulated humans controlling simulated systems. Students can increase or decrease the simulated personnel, but do not participate in determining the results. Constructive simulations provide the following opportunities [2]: analyzing concepts, predict possible outcomes, flow in large organizations, taking measurements, compilation of statistics. Figure 1.

The most effective of these simulations in the power system is Virtual, and its advantage over live simulations is low cost, very low probability of failure, and very short time of repair and commissioning. In constructive simulations, it is not possible to determine values for a specific energy situation.
AR Content and Real World View

Virtual simulations are also known as virtual reality. Virtual reality is divided into 2 types according to its size: 2D - two-dimensional (Figure 2), 3D - three-dimensional.
Three types of three-dimensional virtual simulations are widely used [3]:
Non-immersive virtual reality simulations - these technologies are provided by a computer-controlled virtual environment. Figure 3.
Semi-immersive virtual reality simulations (Figure 4) - Semi-immersive virtual experiences provide users with a partially virtual environment. It still gives users the feeling of being in an alternate reality while focusing on a digital image but allows users to stay connected to their physical environment.
3. Fully immersive virtual reality simulations. This includes simulations that fully involve the user in realtime. In our previous works [5], it was shown that the most optimal architecture for preparing fully immersive virtual reality and simulations is the Unity architecture [3].

The difference between fully immersive virtual reality simulations from other types of virtual reality simulators is that the user forms a complete image of the object being studied, remotely, interactively, and in real-time provides theoretical information to practice. It helps to get full skills through, it is also safe to use. However, the use of fully immersive virtual reality simulations is expensive compared to other types of virtual simulations, and based on this, during our research, we started to prepare both non-immersive and fully immersive simulations at the same time [6, 7, 8] In our next theses or articles, we will reveal information about new types of universal VR simulations.
The most effective types of virtual reality simulations were evaluated using the method of expert evaluation, and the simulation with the highest index was determined based on the following formula [9]

The results show that Full-immersive virtual reality simulations are considered the most effective. Figure 5. Conclusion
It is possible to strengthen the acquired theoretical knowledge by applying it in a practical situation. But there are cases when applying the learned theoretical knowledge to practice can be difficult, inconvenient and even dangerous.
Analyzing the type of simulations, we can see that virtual simulations are the most preferred of the three main groups. In turn, virtual simulators are also divided into three. Non-immersive, semi-immersive, full-immersive. The results of the expert analysis showed that the preparation of full-immersive simulators and their use are considered the most effective.
