This article describes the theoretical foundations and mathematical model of a low-speed permanent magnet electric generator designed for low-head and low-water micro hydroelectric power plants. The equations for determining the balance of magnetic forces in the generator's magnetic system, the saturation coefficient of the magnetic circuit, and the magnetic induction in the air gap are presented. Expressions for voltage, current, electromagnetic power, and torque are generated using a dynamic model based on the d–q axis method. The electrical and energy performance of the generator is evaluated using a simulation model developed in the MATLAB/Simulink environment, and the effect of changes in water consumption on the output parameters is analyzed. The results of the study show that the use of low-speed generators increases the efficiency and reliability of micro hydroelectric power plants.
