摘要
针对传统汽轮发电机转速控制响应慢、无法有效抑制网侧负荷变化引起的应急响应的情况,提出一种基于自抗扰控制的转速控制器。首先,为了精准而快速地评估汽轮发电机组在各种环境下的运行工况,在MATLAB/Simulink仿真环境中搭建了汽轮发电机组的半实物仿真模型。其次,基于自抗扰的控制方法优化了转速控制逻辑,以减少非必要应急控制动作,提高运行效率,最后对汽轮机发电机组的暂稳态进行仿真分析。仿真实验结果表明,基于自抗扰控制的汽轮发电机组在负载变化时能快速恢复稳定,使转速在极小的范围内波动后快速稳定,减少触发应急控制的概率,有效提高了机组运行效率。
In order to solve the problem that the slow response of the traditional speed control adopt on turbo-generator which cannot effectively suppress the emergency response caused by the load change on the grid side,a speed controller based on active disturbance rejection control is proposed.First,in order to evaluate the operating conditions of the turbo-generator in various environments accurately and quickly,a simulation model of the turbo-generator is built in the MATLAB/Simulink simulation environment.Secondly,the speed control logic is optimized by the control method based on the active disturbance rejection control to reduce unnecessary emergency control actions,which improves the operation efficiency.Finally,the transient-steady state of the turbo-generator is simulated and analyzed.The simulation results show that the turbo-generator adopt the active disturbance rejection control can quickly recover stabilize while the grid side load changes,which means the speed can be quickly stabilized after fluctuating within a very small range,reducing the probability of triggering emergency control,and effectively improving the operating efficiency of the turbo-generator.
