ET-89-13 A thesis submitted in partial fulfilment of the requirements for the degree of Master of Engineering Thesis (M.Eng.) - Asian Institute of Technology, 1989 As we known, in almost every engine/generator set a governing system is used to regulate the engine speed under different load conditions by adjusting the fuel supply. The speed of the engine (sometimes voltage) is the only parameter used by the governor, mechanical or electronic one, for adjusting the speed by changing the fuel supply. In this research, the characteristics of biogas, engine and generator and also governing systems have been discussed. Several previous works about this field have been mentioned and some analyses and results of them improved which included a comparison of response and fluctuation of electricity output between mechanical governor system and electronic one with diesel oil alone and as well as with different fuels, diesel oil and biogas, for electricity generation. System with electronic governor has little higher efficiency and smoother output but it is much more expensive. this leads to a less application in rural areas compared with mechanical governor. An experimental investigation on a mechanical governor and a feasibility assessment of a pilot full-scale biogas plant in Thailand have been carried out. It is not economic and acceptable because its net present value CNPV) is less than zero (-107 ,000 Baht). Next, an assumed improved design has been analysed and discussed. It is economic and acceptable with NPV value 57,000 Baht. If we use a electronic governor system for this project, the NPV value (about 17,000 Baht) will be near the breakeven point (NPV=0) compared with its initial capital cost 171,300 Baht. Finally, two models which concern about biogas consumption and different proportion of load have been constructed.
