Optimal Power Factor for the Reactive Load of Small Hydro Power Plants

This article explores the operation algorithm of an excitation regulator of synchronous generators of small Hydro Power Plants (HPPs). The aim is to provide optimum economic parameters, consistent with the dynamically changing requirements of electric supply companies. An integral method for maintaining the power factor has been introduced. The proposed method ensures stable operation of generators in different working modes. It is implemented and the economic effect proved significant
