Application of Tidal Range Influence Model of Seawater Once-through Cooling Circulating Water System

Abstract

The invention relates to the application of a tidal range influence model of a seawater direct-flow cooling circulating water system. By analyzing and processing the tide level and the characteristic data of the circulating water system, the tidal range influence model of the circulating water system is established. Using the model, it can predict the lowest tide level of the target operation mode The characteristics of the circulating water system, combined with the equipment safety strategy, guides the safe operation of the equipment. At the same time, the established tidal range influence model of the circulating water system is used to optimize the operation of the current circulating water system, which can improve the accuracy of the optimization calculation.

Description

technical field [0001] The invention relates to the application of a tidal range influence model of a seawater direct cooling circulating water system. Background technique [0002] The existing circulating water system performance test program is to directly measure the characteristic data of the circulating water system, such as inlet pressure, inlet temperature, outlet pressure, outlet temperature, system water flow and circulating water system motor power under a certain operating mode. The data are fitted and calculated to obtain the inherent performance characteristics of the circulating water system. The inherent performance characteristics of the circulating water system are combined with the condenser characteristic curve family and the steam turbine vacuum micro-increasing characteristics to optimize the equipment operation of the circulating water system, so as to obtain the optimization of the circulating water system under the current unit load and circulating w...

Problems solved by technology

The data measured by the existing test technology is the coupling data of the inherent performance characteristics of the circulating water system and the influence of seawater tide level factors on the characteristics of the circulating water system, and the tide level of seawater is a regular change process, so the obtained during the test As a result, it can only represent the characteristics of the circulating water system at a fixed tidal level, and cannot effectively represent the inherent performance characteristics of the circulating water system, resulting in the calculation results of the performance characteristics of the circulating water system being affected by the tidal level factor and deviating from the actual value. This part is not considered Influencing factors will affect the safe operation and optimal operation results of the circulating water system of the final power plant
