【摘要】：南水北調(diào)工程是解決我國北方水資源缺乏的重大工程,而淮安四站是南水北調(diào)東線工程泵站之一。本文在考慮分時(shí)電價(jià)的基礎(chǔ)上研究淮安四站的運(yùn)行優(yōu)化問題,建立泵站機(jī)組費(fèi)用最小的葉片全調(diào)節(jié)數(shù)學(xué)模型,并針對(duì)該模型特點(diǎn),提出了一種改進(jìn)的動(dòng)態(tài)規(guī)劃求解算法。最后,利用算例驗(yàn)證了該算法的可行性。計(jì)算結(jié)果表明:(1)在設(shè)計(jì)揚(yáng)程、機(jī)組滿負(fù)荷工作情況下,葉片全調(diào)節(jié)的調(diào)度方案與葉片角額定安放角度相比,可節(jié)約費(fèi)用4.88%。(2)機(jī)組能源經(jīng)濟(jì)效率受葉片角和流量負(fù)荷轉(zhuǎn)移兩個(gè)因素影響:其中葉片角與機(jī)組自身的特性曲線相關(guān),當(dāng)揚(yáng)程較大時(shí),葉片角影響較小;流量負(fù)荷轉(zhuǎn)移與機(jī)組容量與需求量相關(guān),機(jī)組容量越大,負(fù)荷轉(zhuǎn)移越顯著。當(dāng)需求量較小時(shí),葉片角是主要影響因素,當(dāng)需求量較大時(shí),流量負(fù)荷轉(zhuǎn)移是主要影響因素。
[Abstract]:The South-to-North Water transfer Project is an important project to solve the shortage of water resources in the north of China, and the Huai'an fourth Station is one of the pumping stations in the East Route of South-to-North Water transfer Project. This paper studies the operation optimization of Huai'an four stations on the basis of considering the time-sharing electricity price. In this paper, a mathematical model of total blade regulation with minimum unit cost is established. According to the characteristics of the model, an improved dynamic programming algorithm is proposed. The feasibility of the algorithm is verified by an example. The calculation results show that under the conditions of design head and full load operation of the unit, the total blade regulation scheduling scheme is compared with the blade angle rating. The energy economic efficiency of the unit is affected by two factors: the blade angle and the flow load transfer: the blade angle is related to the characteristic curve of the unit itself, and the blade angle is less affected when the head is larger; The larger the unit capacity, the more significant the load transfer. When the demand is small, the blade angle is the main influencing factor, and when the demand is large, the flow load transfer is the main factor.
