摘要

燃煤机组参与深度调峰时给水泵再循环控制需要频繁调整

本文针对给水泵再循环自动控制过程中存在的典型问题

采用PID结合流量前馈联合控制、开启速率分区限制、变参数调节、动态下限等控制策略

通过参数优化调整

使机组深度调峰期间汽动给水泵再循环自动控制过程中锅炉给水流量及汽动给水泵流量控制更加平稳

控制偏差及超调量等指标明显改善

有效提高了机组在深度调峰阶段运行的安全性及稳定性。

Abstract

When the unit operating in deep peak regulation

the control of feed-water pump recirculation needs frequent adjustment. To solve the common problems occurred in the process of steam pump recycling control

the control strategies such as hysteresis feedforward + PID

opening rate sectional limit

variable parameter adjustment

and dynamic lower limit are adopted. Through parameter optimization and adjustment

the control of boiler feed water flow and steam pump flow is more stable in the process of automatic control of steam pump recycling during deep peak load regulation of the unit

the control deviation and overshoot are significantly improved

and the safety and stability of the unit operation in the deep peak regulation stage are effectively improved.
