Development Status of Dynamic Distributed Transmission and Distribution System in China

摘要

This paper reviews the studies on dynamic distributed transmission and distribution system and traditional heating distribution system in aspects of mathematical model,structure of pipe network,hydraulic stability of the dynamic distributed system and regulation and control strategy; comparatively analyses the characteristics and difference between each kind of system and summarises the progress and deficiency of existing researches.It is remarkable that pumps should be equipped with various frequency devices to achieve the optimal energy saving effects and regulating efficiency.Many achievements have been realized in each aspects,but there are still disadvantages in the dynamic distributed heating system.All the deficiencies will be the research directions about the dynamic distributed heating system in the future.
