  • A novel stabilisation scheme for hybrid photovoltaic, fuel–cell and diesel gen–set utilisation system

    The paper presents a novel FACTS–based modulated filter compensator scheme for a hybrid renewable photovoltaic–diesel–fuel cell common DC bus interface scheme. The proposed standalone photovoltaic–diesel–fuel system is fully interfaced using the common AC–DC collection bus topology. This allows for full decoupling of AC and DC type green source and ensures full flexibility in controlling the ...

  • A frequency control method for isolated photovoltaic-diesel hybrid power system without smoothing renewable power variations

    In this paper, a frequency control method is introduced for photovoltaic-diesel hybrid system by using a load estimator and an energy storage system. The proposed method is compared with an energy storage based conventional control method and with a fuzzy based frequency control method. Simulation results show that the proposed method is feasible to reduce the frequency deviations of the isolated ...

  • Why ‘custom-built’ is often cheaper than off the shelf

    We know that we’ve said it before, but even though we list what we call our ‘standard range’, by far and away most of the incinerators and cremators we manufacture are specially designed and manufactured to match the individual needs of each customer.  Since everyone’s requirements are different, virtually every unit we produce is ‘made to order’ and the ...

  • Get more out of Water Resources Engineering Models

    The effort required to develop water resources engineering models can be significant. But once developed, in many instances the models are only evaluated for a limited, or a single set of conditions. The results and predictions obtained from these evaluations are the ones used in design, presented in reports and conveyed to decision makers and the public. This approach might serve ...

  • Ferrous Wear Metal Measurement Made Easy with the FerroCheck

    Historically, one of the most cost-effective indicators of machinery health has been the analysis of ferrous debris in oil. Such analysis utilizes the ferromagnetic properties of generated debris to perform the analysis. Since nearly all wear debris contains ferrous material (in particular iron), an abnormal increase in the amount of debris can be directly correlated to abnormal machinery ...
