Abstract

Small synchronous generators connected to electrical power system operate by following changes in the system voltage. Limiting of the generator excitation current enables generator operation within limits of the power chart diagram and increases the safety and availability of generator in the system. This paper includes algorithms for the determination of maximum and minimum excitation current limits and the implementation within digital control system of generator voltage. The performance of generator excitation current limits was experimentally verified on a laboratory model.

Keywords

synchronous generator excitation system; maximum excitation limiters; minimum excitation limiters
