The invention discloses a circulating water control method for a surface indirect air cooling system. The method comprises the following steps that the water inlet temperature threshold value of an inter-cooling tower meeting the energy-saving requirement of the system under the current load working condition is obtained, a corresponding first environment temperature threshold value is obtained, the water outlet temperature threshold value of the inter-cooling tower meeting the anti-freezing requirement is obtained, and a corresponding second environment temperature threshold value is obtained; the current environment temperature is obtained; the obtained current environment temperature is compared with the first environment temperature threshold value and the second environment temperature threshold value, the circulating water flow and / or the cooling air flow can be adjusted according to the comparison result, and the operation requirement of the system can be met. Compared with thefuzzy adjusting method in the prior art, the invention is advantageous in that the circulating water system can be quantified and adjusted according to the environment temperature, and the adjusting precision is improved; the circulating water pump frequency converter is used for adjusting and operating each year according to the scheme, so that the electric charge is saved at least tens of thousands of yuan; the purpose of energy conservation and optimization is achieved, and the energy-saving effect is considerable.
Description
technical field [0001] The invention relates to the technical field of power station energy saving and consumption reduction, in particular to a method for controlling circulating water in a surface-type indirect air cooling system. 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. Indirect air cooling system can be divided into surface condenser indirect air cooling system (surface indirect air cooling system) and condensing condenser indirect air cooling system. [0003] The surface-type indirect air-cooling system is shown in Figure 1. [0004] The surface-type indirect air-cooling system is composed of a surface-type condenser 10 and an indirect air-cooling tower 20 (hereinafter referred to as the indirect cooling tower). This system is basically similar to the conventional wet cooling system, except that the indirect air coo...
