Researching of Heat Consumption Influence at Generator Unit Load in Cogeneration System

Abstract

In recent years, there is an increasing attention to distributed generation in Russia. Distributed generation power systems often use cogeneration (combined heat and power generation) technology. In this paper, the influence of heat consumption at generating equipment loading in cogeneration system is investigated. As an example of cogeneration system, the distributed generation object using gas piston units is taken. In the course of the research, it was found that fuel use efficiency can be increased due to connection the cogeneration plant to the system. Connection to the system allows to vary the generated active power thereby changing the generation of heat energy through cogeneration and to reduce the fuel costs of the station. Also, in the course of the research it was found that the coefficient of fuel utilization is directly proportional to the power loading of cogeneration equipment and is inversely proportional to the number of operating generators. With the correct optimization and connection to the system, it is possible to improve various indicators, including more efficient use of fuel at the station, which in turn will reduce costs and emissions into the earth's environment.
