【摘要】：在濱海非能動核電站中,對廠用水系統(tǒng)(SWS)的安全性和能用度的要求是比較高的,在取水水位變化幅度較大且運行工況較復(fù)雜的情況下,廠用水系統(tǒng)需要長期保持穩(wěn)定、高效的運行狀態(tài)。所以,針對廠用水系統(tǒng)進行優(yōu)化研究對核電站的運行安全有重要意義。本文通過對濱海非能動核電站廠用水系統(tǒng)的系統(tǒng)功能功能、設(shè)計基準(zhǔn)以及運行工況等進行分析研究,梳理出對該系統(tǒng)長期穩(wěn)定、高效運行起關(guān)鍵作用的主要工況和運行模式。然后,對水力學(xué)理論及相應(yīng)的水力學(xué)計算公式進行評價,確定了適合于管網(wǎng)系統(tǒng)的便捷的流體分析軟件AFT對廠用水系統(tǒng)進行輔助設(shè)計和優(yōu)化計算。建立了某濱海非能動核電站廠用水系統(tǒng)的模型,輸入了各關(guān)鍵設(shè)備的阻力系數(shù),針對不同水位條件及不同工況的系統(tǒng)阻力特性確定了系統(tǒng)管徑組合。然后對6種運行組合模式開展水力計算,得到不同配置下的系統(tǒng)流量-阻力特性曲線;再結(jié)合對主要運行工況的分析,得出實際運行工況下系統(tǒng)特性曲線的變化區(qū)域;最后將系統(tǒng)流量-阻力特性曲線和水泵性能曲線相結(jié)合,通過直觀的圖形顯示,將高效運行的概念引入到水泵的選型優(yōu)化中。最后,通過現(xiàn)場反饋的調(diào)試結(jié)果,表明廠用水泵能夠長期處于高效率區(qū)內(nèi)工作,滿足系統(tǒng)長期穩(wěn)定、高效運行的要求。
[Abstract]:In the coastal non-active nuclear power station, the requirements for the safety and energy availability of the water system (SWS) are relatively high. In the case of large variation of water level and complex operating conditions, the water system of the plant needs to be kept stable for a long time. Efficient running state. Therefore, it is important for the operation safety of nuclear power station to optimize the water system. In this paper, the system function, design datum and operation condition of the water system of coastal inactive nuclear power plant are analyzed and studied, and the main working conditions and operation modes that play a key role in the long-term stability and high efficiency operation of the system are sorted out. Then, the hydraulics theory and the corresponding hydraulic calculation formula are evaluated, and the convenient fluid analysis software AFT, which is suitable for the pipe network system, is determined for the auxiliary design and optimization calculation of the plant water system. The model of water system in a coastal inactive nuclear power plant is established and the resistance coefficient of each key equipment is input. The system pipe diameter combination is determined according to the resistance characteristics of the system under different water level conditions and different working conditions. Then hydraulic calculation is carried out for 6 kinds of combined operation modes to obtain the system flow-resistance characteristic curve under different configurations, and then the variation region of the system characteristic curve under the actual operating condition is obtained by combining the analysis of the main operating conditions. Finally, combining the flow-resistance characteristic curve of the system with the performance curve of the pump, the concept of efficient operation is introduced into the selection and optimization of the pump through the visual graphic display. Finally, through the field feedback test results, it is shown that the plant water pump can work in the high efficiency area for a long time, and meet the requirements of long-term stable and efficient operation of the system.
