本文提出一种新的连续-断续自动组合式控制方案,旨在能够大幅度降低一些功率单元可分组的大容量自控系统的初投资。该方案表明:系统可由单一的给定信号控制,可用传统的控制方法设计,组合简便。系统晶闸管的容量尽管大部分可由接触器代替,内部自动协调装置却能使系统输出呈一近似全连续的控制特性,而且会延长接触器的使用寿命。 In this paper, a new continuous-intermittent automatic combined control scheme is proposed, which can reduce the initial investment of a large number of high-capacity automatic control systems that can be grouped in some power units. The scheme shows that the system can be controlled by a single given signal, which can be designed by the traditional control method, and the combination is simple. Although most of the capacity of the thyristor system can be replaced by the contactor, the internal auto-tuning device can make the system output has an approximately fully continuous control characteristics, and will extend the life of the contactor.
