摘要：隨著我國電力工業的迅速發展，越來越多的高參數大容量機組陸續投產。從發展趨勢看，600MW及以上等級的火電機組已成為大電網的主力機組，同時大容量機組的不斷增加和電網調度自動化程度的日益提高，對火電廠機組的控制品質提出了更高的要求。主蒸汽溫度是鍋爐運行中的主要參數，它的高低直接影響鍋爐安全穩定運行。鍋爐主汽溫控制有非線性和時變性，其大延時和大慣性的特點使其一直以來都成為火電廠自動控制的難點。本文中，針對大容量機組中過熱蒸汽大延時和大慣性的特點設計一個串級模糊控制器，并對其進行仿真，研究其動態特性與魯棒性。

關鍵詞：過熱器；過熱汽溫；串級PID；串級模糊控制

Abstract: With China's power industry developing rapidly, more and more large-capacity high-parameter units have put into production. From the development trend, above 600 MW unit will become a main unit of the power grids in the future. With the increasing of the largecapacity unit and the increasing degree of automation of the scheduling grid, it is a higher demand to the quality control of the thermal power plant unit. Supercritical generating units is the development of largecapacity generating units in China will also become the main force units. The main steam temperature is the main parameters in the boiler operation, which affect the safe and stable operation of boiler directly. The control of main steam temperature in the boiler is nonlinear and time variability. It is very difficult to control for the large delay and the inertia of its characteristics. In this paper, in view of the large inertia and large delay of superheated steam in the large capacity unit, we design a cascade fuzzy controller and carries on the simulation to research on its dynamic characteristics and robustness.

Key words: Superheater unit; Superheated steam; Cascade PID; Cascade fuzzy control
