摘要
冰浆式蓄冷空调系统有助于电网"削峰填谷",具有良好的经济性能,是近年来电能替代技术中极具发展潜力的一类装置。为了研究冰浆式蓄冷空调系统的动态特性及控制方法,基于机理辅以经验,采用集总参数法建立了系统各部件的动态数学模型,并在Simulink中构建了系统的仿真模型。针对谷电段的蓄冰工况,将室内温度及蓄冰槽内蓄冷量作为被控参数,提出了基于多变量模型预测(MPC)的控制方案,并利用Matlab/Simulink实现了控制仿真,控制仿真结果表明了MPC算法的有效性,为解决冰浆蓄冷空调的多变量控制问题提供了一种思路方案。
Based on the principle and the experience,the dynamic mathematical model of each component of the system is established by lumped parameter method in this paper.The simulation model of the system is built by Simulink.For the ice storage conditions in the valley electricity price period, the indoor temperature and the cold storage capacity in the ice storage tank are used as controlled objects,and a control scheme based on multivariate model prediction （MPC） is pro- posed,and the control simulation is implemented using Matlab/Simulink.
