AI Technical Summary

Technical Problem

Traditional control schemes have failed to effectively coordinate the frequency regulation needs of thermal power units, resulting in poor boiler-turbine coordination, large fluctuations in thermal parameters, frequent fuel adjustments, and low frequency regulation qualification rates. They are ill-suited to the comprehensive frequency regulation needs of new power systems, which are characterized by high frequency, rapid changes, and wide load ranges.

Method used

The turbine main control command control system adopts a new power frequency regulation coordination method. By introducing multi-source input commands, it uses the main steam pressure setpoint as the control anchor point for unit energy supply and demand balance. Combining the measured values ​​and the unit target load benchmark without primary frequency regulation, it uses intelligent turbine flow commands to achieve the unification of multi-dimensional control objectives, generate control commands that directly drive the turbine regulating valve switch, and optimize the boiler-turbine system.

Benefits of technology

While ensuring the unit's rapid frequency regulation performance, it stabilizes the unit's main steam pressure parameters, avoids interference between the turbine and boiler regulation, improves the overall operational safety and comprehensive frequency regulation performance of the unit, and achieves coordinated energy constraints between the turbine and boiler.

Abstract

本发明公开了一种新型电力调频下协调方式汽机主控指令控制系统及方法,属于火电机组的智能控制技术领域。本发明通过引入多源输入指令实现控制,首先通过主蒸汽压力设定值提供一个目标控制值,其次以主蒸汽压力输出的实测值实时表征锅炉侧能量输入与汽机侧能量输出的动态平衡状态,并利用未经一次调频动作分量叠加的机组目标负荷基准指令,然后利用智能汽机流量指令将多维度控制目标转化为统一基准,消解多源指令冲突实现机炉系统优化,最终生成直接驱动汽机调门开关动作的控制指令,在保障机组快速调频性能的同时,稳定机组主汽压力参数,避免机炉调节干涉,实现机炉能量协同约束,并提升机组整体运行安全性与调频综合性能。
