Abstract

This article tackles the optimization of crankshaft rotation frequency regulators in high-power diesel generators. These generators play a crucial role in the energy efficiency of standalone cogeneration plants. The research focuses on determining the optimal number of teeth on the measuring gear. This factor is crucial for ensuring frequency regulation stability. Nonlinear pulse control methods were applied, and transient processes were modeled. The results show how the number of teeth impacts the accuracy of sampling frequency measurement and regulation efficiency. The novelty of this work lies in the comprehensive analysis of how gear teeth affect the regulation process. A method for selecting the optimal number of teeth has been developed. This significantly eases the adjustment of regulators and cuts costs in implementing modern electronic control systems. This work has practical implicatiowns for upgrading energy systems based on diesel generators, promising improved energy efficiency, reliability, and longevity.
