Study of Engine and Alternator Control System of Captive Power Plant.

Abstract

This paper discloses about whole Power Generation Structure of Bangladesh, daily demand of DESCO, DPDC, BPDB. We also try to find out: why is the crisis in power generation in Bangladesh and its solution, why is the Captive Power generation necessary? What kinds of Power plants are suitable for captive Power Generation in Bangladesh? Diesel Engine Power Plant Vs Gas Engine Power plant with mathematical analysis. This thesis also includes the Necessity of power plant, History of power plant .It deals with brief discussion about different parts of ENGINE, Its control system ( i.e. Lambda control, Ignition control),different trouble shooting and its causes as well as remedies. Last but not a least. We discuss the different parts of AC Generator system and its protective system. This paper deals with ignition control, or more specifically with spark advance control, i.e. how long before top dead center (TDC) to ignite. The idea is to control the spark advance so that the pressure peak is placed relative to TDC in an optimal way. Work is lost to compression and heat transfer if it is placed too eaxly, and expansion work is lost if it is placed too late. A key problem is thus to find a description of the ionization current that is rich enough to capture the different variations, but still such that the relevant information can be extracted.
