中文摘要	多联产系统以电力为主要的产品之一,因而在运行时必然要面对变负荷的问题。本研究从变负荷的角度考虑如何设计多联产系统以满足电网的要求。通过详细的仿真分析,提炼出影响并联多联产系统变负荷能力的两个主导因素:设计动化比和合成单元容量盈余度。以四象限图的形式展示主导因素与系统变负荷能力的关系,并进一步分析系统在变负荷运行时的特性。分析结果揭示了联产系统变负荷运行时发电单元和化工单元的负荷分配规律及系统热效率随电负荷的降低而提高。; Electric power is one of the main products of a polygeneration system.Therefore,it will unavoidably encounter load variation problems during its operation.From a load variation viewpoint,the authors have mulled how to design a polygeneration system to meet the requirements of an electric network.Through a detailed simulation analysis,two leading factors influencing the load variation ability of the parallel polygeneration system have stood out,i.e.design power/chemical ratio and synthetic unit capacity surplus.The relationship of the leading factors and the system load variation ability was shown in the form of a four-quadrant chart.In addition,the characteristics of the system operating during load variations were further analyzed.The results of the analysis reveal the law governing the load distribution between a power generation unit and chemical engineering one during the load variation operation of the polygeneration system as well as the fact that the thermal efficiency of the polygeneration system will increase with a decrease of the electric load.
