What is a frequency regulator?

A frequency regulator is a device used in power systems to maintain the stability of the electrical grid by controlling the frequency of the generated electricity. It adjusts the output of power plants in response to changes in demand or supply, ensuring that the frequency remains within a specified range. This is crucial for the reliable operation of electrical equipment and the overall stability of the power grid. By managing frequency fluctuations, frequency regulators help prevent blackouts and ensure efficient energy distribution.
