摘要: 以500 kW-TICC系统为研究对象,采用集中参数法建立了系统储能设备的集总参数数学模型,然后用C语言编写相应的程序算法,对所建算法进行算法入库,在华北电力大学STAR-90仿真支撑系统上搭建系统实时动态仿真模型,对500 kW-TICC储能阶段冷态启动阶段进行仿真。分析了压气机环节、换热器环节、储气罐环节和储热罐环节的动态特性。仿真结果表明,进气流量对系统储能阶段参数的影响较大,储气室内气体的温度变化比较平缓。此仿真结果误差满足实际需要,对系统实际运行的动态特性有很重要的参考和借鉴作用。

关键词: TICC-500系统, 仿真模型, 动态特性

Abstract: A mathematical model was established for a 500 kW-TICC energy storage system using the lumped parameter method. An algorithm was built to solve the model  with a C-language based program. The program was integrated into the North China Electric Power University’s Star-90 simulation support system for real-time dynamic modelling of the cold start of the 500 kW-TICC system. Analyses were done on the dynamics of various components including compressor, heat exchanger, storage tank, and thermal store. The simulation results show a significant impact of the intake air flow rate on the system parameters at the storage phase, whereas the effect on the gas temperature change in the gas chamber is relatively flat. This simulation errors were found to meet the actual needs of the dynamic system characteristics.

Key words: TICC-500 system, the simulation model, the dynamic characteristics
