| 作者单位： | 某660 MW超临界机组在大修期间经DCS升级后，各系统调节机构的热态特性发生改变，对原有RB（快速减负荷）控制回路带来一定的影响，基于此，需要对该机组的性能进行评估和对控制系统进行优化。经过对该机组进行燃料、送/引风机、一次风机、给水泵RB试验，同时根据相关试验曲线、参数和控制逻辑，对该机组控制系统进行优化。试验结果表明：该机组完全达到设计的运行参数，且主汽压力、主汽温度、炉膛负压等参数指标控制稳定。RB功能完善可靠，在辅机发生故障时，能够确保机组仍能安全稳定地运行。 |

| Affiliation: | For a certain 660 MW supercritical unit, once the DCS is upgraded, the hot state characteristics of the system adjusting mechanism will change, leading a certain effect on the original RB (Fast load reduction) control circuit. Based on this reason, it needs to evaluate the performance of the unit and optimize the control system. The RB tests of this unit on fuel, forced/induced draft fan, primary air fan and feed water pump were conducted, along with RB test curve, parameters and control logic, optimizing the unit control system. The test results show that the unit completely meets the designed operation parameters, among which the main steam pressure, the main steam temperature and furnace pressure are controlled steadily. The RB function is reliable, ensuring the unit safe and stable operation when the auxiliary unit malfunctions. |
