In order to improve the quality of power supplied by medium and small-sized diesel generator which was applied an islanded load, a digital electronic speed control system was designed in this paper. For adapting the broad load characteristics, the structure of Variable-Speed-IntegratedGenerator (VSIG) was adopted by the diesel generating set. The proposed governor used a fuzzy self-tuning proportion-integralderivative structure controller that can provide variable gain strategies to account for nonlinearities in the system. The results of test were obtained by a 3kW naturally aspirated diesel generator which was applied islanded load. The test results showed that the system designed had integrated functions of speed regulating and good speed characteristics.

“…Diesel gensets are also used in remote locations where it is impractical or too expensive to connect to a utility grid. The generator in a genset is commonly a PMSG or an EESG, in the case of a PMSG, it usually needs a rectifier and a power converter to provide the necessary AC voltage at the rated frequency (Al-Khayat et al, 2002). …”

In distributed energy systems, permanent magnet synchronous generators (PMSG) are often connected to the grid via power converters, such as voltage source converters (VSC). The price of the converter constitutes a large part of the costs of a variablespeed turbine (driven either by wind or ocean energy system) and is often required in order to conform to stringent grid codes imposed by transmission system operators (TSOs). While the addition of these components assure compliance they have an impact on the overall reliability and, in an offshore environment, the reliability factor is paramount. A new approach which can be taken by the industry is to rethink the design of their offshore energy devices. In a "farm" like configuration, a different approach can be taken to make the farm compliant rather than involving each individual device.This approach can also be applied for any offshore renewable energy system using synchronous generators. Furthermore onshore locations could benefit from this configuration especially when remote.The performance of the new approach is analyzed, while general guidelines and recommendations imposed by the industry are applied in the analysis. By analyzing the results produced by the simulation model the guidelines for efficient synchronization and load sharing are presented. The simulation model is used to simulate generator paralleling, electromagnetic torque analysis and load transients. A scaled down prototype Wind Farm (WF) was also constructed and its results analyzed and compared to the simulation model. Practical measurements and observations are highlighted and analyzed. Wind speed is entered in the model to simulate behavior of the new approach in different conditions. Fault ride through and ride through capabilities of the model are also partially studied.Keywords: permanent magnet synchronous generators, power converters, synchronization, load sharing, electromagnetic torque, wind turbine design, reliability, offshore renewable energy systems, ruggedized offshore wind turbine design.ii iii Declaration I hereby declare that this submission is my own work and that, to the best of my knowledge and belief, it contains no material previously published or written by another person nor material which has been accepted for the award of any other degree or diploma of the University or other institute of higher learning, except where due acknowledgment has been made in the text.

“…Therefore, conventional IC engines don't utilize the full speed range of the engine on the application or removal of electrical loads. Using a power electronics interface with an IC engine offers the advantage of having variable speed operation of the IC engine, which in turn optimizes fuel usage for varying loads (AI-Khayat et al 2002). The engine speed can be controlled in response to load changes to optimize the combined efficiency of the engine and generator.…”

“…The generator converts mechanical energy from the IC engine to a variable voltage, variable frequency output that varies with engine speed. The rectifier and inverter are then used to convert the output of the generator to a power that is compatible to the utility system (AI- Khayat et al 2002;Van Tichelen and Weyen 1998). For the induction generator, a reactive power compensator may be required.…”
