Electromagnetic ferromagnetic oscillatory circuits having falling sections on the amplitude characteristics formed the basis of stabilizers based on the principle of summing the currents of individual branches. A distinctive feature of such stabilizers is that the current remains unchanged both when the load resistance changes, so when the input voltage varies over a wide range. This is required by devices such as electromagnets of physical instruments, electromagnetic lenses of electron microscopes, instruments for emitting nuclear paramagnetic resonance, instruments and devices of various automation schemes, measuring and computing equipment, as well as many electrotechnological processes. Therefore, current stabilization has long attracted the attention of many researchers, and this is still one of the important problems of electrical engineering. The curve shape of the proposed current stabilizer is close to a sinusoid, the power factor is very high, since the device operates in capacitive mode.

In this paper we consider the application of graph-analytical method for the analysis of the load regime of ferromagnetic current stabilizer. It is proved that under active load the current of the ferromagnetic stabilizer and magnetic flux are related by the ellipse equation where the axes coincide with the axes of coordinate system. The advantage of the proposed method is that it is possible to use an experimentally obtained characteristic.

The possibilities and the effectiveness of using various methods of controlling the loads of electric consumers are determined with the conditions of the balance of capacities and electricity in the power system. In this regard, the article analyzes the current state and assesses the immediate prospects for ensuring a balance of capacities and electricity in the energy system of the Republic of Uzbekistan.

In this paper, the process of methane replacement in gas hydrate with carbon dioxide during CO2 injection into a porous medium is studied. A model that takes into account both the heat and mass transfer in a porous medium and the diffusion kinetics of the replacement process is constructed. The influences of the diffusion coefficient, the permeability and extent of a reservoir on the time of full gas replacement in the hydrate are analyzed. It was established that at high values of the diffusion coefficient in hydrate, low values of the reservoir permeability, and with the growth of the reservoir length, the process of the CH4-CO2 replacement in CH4 hydrate will take place in the frontal regime and be limited, generally, by the filtration mass transfer. Otherwise, the replacement will limited by the diffusion of gas in the hydrate.
