Means of Complex Design of the Electromechanical System of the Gravity Energy Storage of the WindPower Plant

A complex mathematical model of the electromechanical system of the gravity energy storage of a wind power plant and the expression of the criterion of its optimal design as the ratio of the efficiency of the system according to the final result to the value of energy resource are developed. The model is implemented in the Matlab simulation system for optimization research in conditions of constant and variable wind speed taking into account the mutual influence of system components: electric generator and motor, reducers, electric network, power frequency converter, hoisting installation. On the example of a system with a capacity of 40 kW, the patterns of change of complex energy coefficients are studied, the efficiency of the developed means of optimal design is substantiated.
