分布式供能及其系统集成

分布式供能系统直接面向用户,满足用户冷、热、电等多种能源需求,具有高效、环保、可靠、经济等特点。分布式供能系统与电网等集中式供能系统的互补是未来可持续能源利用技术的发展方向。分布式供能系统的关键技术包括微型、小型动力技术,中低温余热转换和利用技术,以及系统集成技术,是实现系统大幅度节能最有效的手段。本文提出了分布式供能系统集成应当遵循能的综合梯级利用,能源、资源和环境的综合互补,以及全工况系统集成等原则。

Distributed Energy System and Its Integration

The distributed energy system(DES) directly and simultaneously supplies end-users with energy in different forms such as electricity, heat, and cold. As it is an efficient, environment-friendly, economical and small energy system, and its complementary use along with the conventional power grid will become a promising direction for sustainable energy utilization technologies. The crucial technologies of the DES include micro-small power, middle-and-low temperature thermal energy utilization and system integration technology. The DES is the most effective method for energy conservation in a big way. The system integration principles of the DES is discussed, including the comprehensive cascade utilization of energy, the energy, resources and environment supplementary synthesis, as well as system integration under all-operating conditions.
