2 サイト地域電熱供給システムの安定性 —熱融通指令値のステップ状変化に対する数値的検討

抄録

This paper is concerned with stability of a regional power and heat supply system. The system has two combined heat and power plants (or co-generation units) supplying both power and heat. A mathematical model is derived to represent dynamics occurring in the system due to the coupling between power network and heat network. Numerical simulations of the model are performed for investigating its static and dynamic characteristics in order to estimate the stability of the system. It is shown that the heat transfer management between the two co-generation units affects the stability of the system and possibly destabilizes the synchronized operation of the two generators.
