Description

Nuclear power plant controlled equipment control device

Technical Field

The utility model relates to a control system technical field, concretely relates to nuclear power plant is controlled equipment controlling means.

Background

In the last 70 th century, the energy crisis caused by the price rise of petroleum has promoted the great development of nuclear power. Most of four hundred nuclear power units which run commercially in the world are built in the period, and are conventionally called second-generation nuclear power units.

The united states nuclear power User Requirement Document (URD) and the european nuclear power user requirement document (EUR) propose safety and design technical requirements of next generation nuclear power plants, which include reformed active (safety system) nuclear power plants and advanced passive (safety system) nuclear power plants, complete all engineering demonstrations and experimental work and preliminary design of the nuclear power plants, and they will become the main reactor type of the third generation nuclear power plants.

Compared with the second generation nuclear power plant, the number of million kilowatt nuclear power plant field safety level actuating mechanisms of the third generation nuclear power plant is greatly increased. The number of field devices controlled by the nuclear-grade instrument-control DCS is nearly thousands, which is about 3 times of that of the second-generation nuclear-grade engineering, wherein the number of devices needing to be started, stopped and switched in manual and automatic modes is far larger than that of the second-generation engineering, and the redundant configuration in a single column or across columns is increased for the field devices. Relying entirely on single device control, either manual or automatic, is detrimental to the positioning of the device and may even cause a lag in the operational response.
