Abstract

Blending hydrogen into a natural gas pipeline system for transportation changes the dynamic characteristics of the gas, and consequently, disturbances caused by valve misoperation, water hammer, and other factors will have a greater impact on the safe operation of the pipeline. This article establishes a boundary control model for pipeline transportation systems, which controls the safe operation of hydrogen doped natural gas pipeline transportation systems by regulating pressure and flow rate. Using the model predictive control method, the constraint relaxation variables and safety index are used as the constraint conditions for the quadratic optimization function, ensuring the safe operation of the pipeline system during the process of solving the control variables. Finally, the model predictive control simulation under water hammer conditions proves that the control strategy can effectively suppress the fluctuation of state variables, ensuring the safe and stable operation of pipeline transportation systems.

含氢天然气管道压力-流量双控制建模与安全控制

在天然气管道系统中掺入氢气进行输送会改变气体的动态特性，因此，由于阀门误操作、水锤等因素引起的扰动会对管道的安全运行产生较大影响。本文建立了管道输送系统边界控制模型，通过调节压力和流量控制掺氢天然气管道输送系统的安全运行。采用模型预测控制方法，将约束松弛变量和安全指标作为二次优化函数的约束条件，在求解控制变量的过程中保证管道系统的安全运行。最后，通过水锤工况下的模型预测控制仿真，验证了该控制策略能有效抑制状态变量波动，保证管道输送系统安全稳定运行。
