Analyzing the Digitally Levelled Control Systems Used for Nuclear Power Plants

Abstract

This paper analyzes the digitally levelled control systems used for the nuclear power plants. The main contents are as follows: Through describing the expression of DCS, the accurate concept of the digitally levelled control system is highlighted. The level model of the digitally levelled control system is provided here by examples. The comparison is done here, in which the difference of classification to the same subsystems in the different digitally levelled control systems used for the nuclear power plants is clearly shown. The digitally levelled control system used for the nuclear power plant is a network system. Its safety belongs to one part of the whole nuclear safety. Here, the paper will concisely discuss the safety problem according to the nuclear safety principle of defense in depth. But the notice must be pointed out that the principle of defense in depth does not only exist in the nuclear energy systems, also in the industrial control systems.
