摘　　要：分析了超超临界火电机组深度调峰工况运行的控制特点和需求,针对大容量机组控制策略不完善及参与深度调峰运行过程中存在的水动力安全等方面问题,开展设定值函数完善、负荷变动速率自适应、低负荷煤水控制等策略优化。对某1000MW超超临界机组进行深度调峰控制优化后进行动态试验,试验结果表明:机组主要控制参数动态、稳态误差均满足相关规程要求,所用控制优化方法能够有效提升机组灵活性调节品质。The control characteristics and requirements of deep peak regulation operation of ultra-supercritical thermal power units are analyzed.In view of the imperfect control strategy of large capacity thermal power units and the hydrodynamic safety problems existing in the process of participating in deep peak regulation operation,strategy optimization is carried out,such as improvement of setting value function,load change rate,low load coal water control and so on.The dynamic test of a 1 ooo MW ultra-supercritical thermal power unit after deep peak regulation control optimization is carried out.The test results show that the dynamic and steady-state errors of the main control parameters of the thermal power unit meet the requirements of the relevant regulations,and the control optimization method can effectively improve the flexible regulation quality of the thermal power unit.
