IMMEDIATIVE MODEL OF THE CHARGING PROCESS OF THE EMCSENTIAL AC-CUMULATOR OF THE ELECTRODYNAMIC DRIVER PUMP IN ALONE STATE WINDTURBINE
Capacitive drives, as a necessary component, are widely used in a variety of electrical installations and systems. The analysis of known approaches to increasing the efficiency of the charging circuit has shown that they are associated with certain difficulties. For example, chargers with sources regulated under a certain voltage law are complex and their application can only be justified in exceptional cases. In addition to the converging power source and the capacitive drive additional reactive elements are required that store energy and maintain the input and output levels at the same level during the charging process. This requirement plays a significant role in the case of the use of a source of limited power. In most cases, the energy processes of the charge of the capacitor were analyzed at zero initial conditions.
The maximum efficiency can be achieved with a constant input and output current. To achieve the maximum efficiency of the converter in the initial period of time should store energy to end the charge to give stored energy to maintain the charge current.
The wind turbine works under stochastic conditions of changing the level of wind speed, which leads to the corresponding indicators on the charger terminals. Estimation of the required amount of energy for charging a capacitive drive for the above-mentioned dependence is complicated.
The purpose of the work was to determine the time of charging the capacitive drive of the electrodynamic actuator of the pump of the autonomous wind power plant to the given technological limits by means of simulation modeling under stochastic conditions of changing the level of wind speed. When changing the values of the mathematical expectation of wind speed in the range of 4...5,2 m/s, when charging a capacitive drive, at the technological limit of voltage 100 V, is, respectively, 12.5 ... 7s.
