Example Embodiment

[0040] The specific embodiments of the present invention will be described in further detail below in conjunction with the drawings and embodiments. The following examples are used to illustrate the present invention, but not to limit the scope of the present invention.

[0041] figure 1 It is a schematic diagram of the surface condenser indirect air cooling system structure as the basis of the surface condenser indirect air cooling control system of the present invention; figure 1 As shown, the basic thermal process of the indirect air cooling system of the surface condenser is: three circulating water pumps circulate the circulating cooling water from the radiator (steel cooling triangle) of the air cooling tower to the inside of the surface condenser. The exhaust steam from the low pressure cylinder of the steam turbine enters the steam side of the condenser and is condensed into condensed water by the circulating water on the water side. After being heated, the circulating wa...

Abstract

The invention discloses an indirect air-cooling control system of a surface condenser, comprising a startup control device, a stop control device, a bypass valve control device, a liquid level control device for an underground water tank, a liquid level control device for an expansion water tank, a water charging/discharging control device and a circulating water temperature control device, wherein the bypass valve control device, the liquid level control device for the underground water tank, the liquid level control device for the expansion water tank, the water charging/discharging controldevice and the circulating water temperature control device are respectively connected with the startup control device and the stop control device. The indirect air-cooling control system of the surface condenser can be integrally connected with a DCS (Distributed Control System) in host computer room, which is good for expanding the system network; operator on duty is unnecessary near the air cooling tower, so labor cost is saved. The indirect air-cooling control system is high in automation degree, simple in operation, good for the operation of the operators, and is capable of excellently solving the antifreeze problem of the radiator when the radiator operates in winter.

Description

technical field [0001] The invention relates to the technical field of power station cooling, in particular to an indirect air cooling control system for a surface condenser. Background technique [0002] According to the different cooling principles, the air cooling system of power station can be divided into direct air cooling system and indirect air cooling system. The indirect air cooling system can be divided into surface condenser indirect air cooling system and condensing condenser indirect air cooling system. At present, in northern China, direct air-cooling units are used on a large scale, while indirect air-cooling units with surface condensers are relatively few, and there is no operating experience in large-capacity surface condenser indirect air-cooling control systems. The control scheme of this type of indirect air cooling system has been in the hands of foreign companies. Foreign companies generally use PLC (Programmable logic Controller, programmable logic...
