摘要:

主蒸汽温度具有大惯性、大迟延、非线性及不确定性强等特点,针对这种复杂控制对象,采用了给水/燃料比优化控制方案对主蒸汽温度进行控制。通过分析机组运行实时曲线,验证了该方案的有效性。

关键词: 主蒸汽温度, 大惯性, 给水/燃料比, 优化控制

Abstract:

The main steam temperature has characteristics of the large inertia, the large delay, the nonlinearity and strong nondeterminacy. Aiming at this complex control object, an optimal control scheme based on water/fuel ratio was adopted to control the main steam temperature. The analysis of the real time operation curve of the unit shows that the scheme is effective.

Key words: main steam temperature, large inertia, water/fuel ratio, optimal control
