MITIGATION OF CORE AND WINDAGE LOSSES IN A SYNCHRONOUS GENERATOR FOR IMPROVED PERFORMANCE
Losses in motors and generators have become a source of concern to machine designers and fabricators. Performance of these machines depend largely on the different losses that results in the course of the machine operations. This research is tailored on the mitigation of these losses in synchronous generator. The objective of this research, is to study how windage and core losses in synchronous generator can be mitigated and improve overall engine efficiency. The method adopted is the modeling and simulation of a synchronous generator using MATLAB® and Simulink® to know the effect of core and windage losses. When the reactive power generated before mitigation and after mitigation of the losses, were simulated , the result showed that reactive power generated with losses was 0.0041Pu and after mitigation it was 0.0095Pu. Also when real power was simulated before and after mitigation, the result showed -0.11Pu and 0.17 Pu respectively. This research also proffers economical ways in which open-circuit or no-load losses can be significantly reduced, without compromising generator’s efficiency.
