A power plant, 2×300MW coal-fired units

The thermal system is a unit system . Each unit is equipped with a centralized control building, which adopts the centralized

control mode of machine , furnace and electric unit . The elevation of the unit control room is 12.6m, which is consistent with

the elevation of the operation floor . DCS adopts WDPF-Ⅱ, and the I/O points designed for each unit are 4500 points.

The number and length of the above cables do not include the factory-supplied cables for the fire alarm of the whole plant 

and the cables of the auxiliary production workshops of the whole plant .

The cables of the power station can be divided into six categories :

High-voltage power cables , low-voltage power cables , control cables , thermal control cables , weak current cables

(mainly refers to computer cables ), and other cables . If two 300MW units do cable laying at the same time, the number of

professional automation cables will be about 8,500 . Among them, there will be more than 500 thermal control cables and

weak current cables, accounting for about 60% ( measured by the number of cables ).
