Analysis on Thermoelectric Decoupling Technology Paths for Thermal Power Units Under the Background of Deep Peak-Shaving
摘要
Abstract
New energy power generation has the charac-teristics of large fluctuation and instability in output and power generation load.In order to solve the above problems brought by new energy units on the internet,a variety of thermoelectric decoupling modes was used to transform thermal power units,different technology paths were analyzed,and the potential of decoupling thermal power units and peak shifting capacity was explored.EBSILON professional software was used,and the peak load space under different thermoelectric decoupling schemes was evaluated and compared.The results show that the zero output thermoelectric decoupling transformation scheme of low pressure cylinder can improve the peak regula-tion capacity of the unit to the greatest extent.Under the origi-nal maximum heating load of 304.60 MW,the minimum power generation decreased by 172.21 MW,and the minimum power load rate decreased by 32.70%.Thermal power units after heat and power decoupling transformation can significantly improve the coordinated peaking ability of thermoelectric units and new energy units,and improve the stability of the overall power gen-eration of power generation units.关键词
