Abstract

In this paper, a control system for monitoring and controlling the performance parameters of diesel generators has been designed and presented. In most existing monitoring and control systems for diesel generators, when the operational parameters of the generator exceed the permissible limits, the system shuts down the diesel generator and de-energizes the loads connected to it. However, in the proposed method, by accessing the breakers of the generator’s output feeders, appropriate control commands are applied only to a portion of the loads. Moreover, to prevent the effect of non-linear loads on the generator’s output voltage, the proposed monitoring system is equipped with a control algorithm that calculates the amount of load shedding required to return the voltage to the standard conditions and manages the loads connected to the generator accordingly. Furthermore, the proposed method is equipped with an adequate user interface and hence can be easily applied in industrial environments. The proposed load control algorithms also consider the effect of the nature of the load on the diesel generator’s capacity reduction, and the effect of non-linear loads on the diesel generator’s capacity reduction has also been considered.
