ガスエンジン・コージェネレーション・システムの動特性分析

Dynamic characteristics of a gas engine cogeneration system are analyzed using a simulation model. DYNAMO(dynamic model) is adopted as a simulation language because it enables an easy and flexible change of model structure and parameters. Dynamic characteristics of each piece of constituent equipment are expressed by using dead time and first-order lag elements. Their parameters are determined so that the simulation results match the measured ones accurately enough. The simulation model of the whole system is created by linking each submodel of constituent equipment. The simulation and measurement results show that the proposed modelling method is a useful tool. As an example of dynamic simulations, it is investigated how the location of measurement points influences the temperature of jacket water for cooling the gas engine.
