Abstract

Chinese Modular High-Temperature Gas-Cooled Reactor HTR-PM is a promising energy source for comprehensive utilization. The original coordinated control strategy of HTR-PM is a “turbine following reactor” strategy, which is not able to perform load following operation. To have more flexible operation capability, this paper presents a load following control strategy for HTR-PM. A balance of plant (BOP) model of HTR-PM is first developed for dynamic simulation, including the once through steam generator (OTSG), turbine generator, condenser, feed water heater, deaerator, feed water pump, valves and piping system. Then the original coordinated control strategy and the proposed load following control strategy are clarified, and model validation, simulation results are documented respectively. For turbine trip without reactor shutdown from 100%PFP transient, the steam dump strategy is improved to meet the safety requirements. Results demonstrate that the proposed load following strategy can meet the requirements of safety operation, which is desirable for participation in peak load regulating of power system.
