In the GSE simulation system,JTopmeret modules are employed to establish the whole steam test system,the optimizati­on of the modules and correction of parameters are processed on the basis of the data detected in the steam test,and the simulation data is compared with the experiment­al data to verify the accuracy and validity of the simulation model. [Results] For the control requiremen­ts of reducing steam flow linearly by 20 t/h within 10 s,the simulation results show that the open-loop control scheme allows the control of boundary conditions to be achieved after several iterations,while using the traditiona­l PID closed-loop control scheme makes it difficult to control the boundary as required. The test results show that the flow change at the steam inlet meets the test requiremen­ts of the bench test,and is consistent with the simulation results.[Conclusion­s]The results of this research can provide references for the boundary control of steam system bench tests. conditions;simulation;GSE;control system;steam system bench test
