摘要：隨著環(huán)保要求的不斷提高，城市集中供暖小鍋爐被逐步關(guān)停，并被接入城市主干網(wǎng)，熱網(wǎng)不斷擴(kuò)張。與此同時(shí)，熱量的生產(chǎn)也運(yùn)用地?zé)帷⑻柲堋⒐I(yè)余熱、電熱等多種熱源，使得集中供熱系統(tǒng)變得更加復(fù)雜。靠傳統(tǒng)手工運(yùn)算方式、或者理想機(jī)理建模方式較難對熱網(wǎng)的結(jié)構(gòu)設(shè)計(jì)及運(yùn)行進(jìn)行科學(xué)優(yōu)化，需要通過計(jì)算機(jī)仿真建模的手段，并結(jié)合實(shí)際熱網(wǎng)運(yùn)行的數(shù)據(jù)對熱網(wǎng)進(jìn)行阻力特性辨識，才能真正起到有效的作用。本文研究了基于數(shù)據(jù)驅(qū)動與機(jī)理模型融合的集中供熱網(wǎng)水力平衡分析模型，并利用來自熱網(wǎng)SCADA運(yùn)行數(shù)據(jù)通過多種機(jī)器學(xué)習(xí)算法對先驗(yàn)知識模型的參數(shù)進(jìn)行學(xué)習(xí)優(yōu)化，最終建立與真實(shí)熱網(wǎng)相匹配的水力分析模型，此種方法可為熱力企業(yè)的熱網(wǎng)結(jié)構(gòu)優(yōu)化改造、經(jīng)濟(jì)運(yùn)行提供技術(shù)參考。

Abstract: With the continuous improvement of environmental protection requirements, small boilers for urban central heating are gradually shut down and their heating network are connected to the urban backbone network，therefore，the urban central heating network continues to expand. At the same time, heat production also uses multiple heat sources such as geothermal, solar, industrial waste heat, and electric heating which make the central heating system more complicated. It is difficult to scientifically optimize the structure design and operation of heat supply network by traditional manual calculation methods or ideal mechanism modeling methods. In order to really play an effective role, it is necessary to identify the resistance characteristics of the heat supply networks by means of computer simulation modeling and combined with the actual heating grid operation data. This paper studies the hydraulic balance analysis model of the central heating network based on the fusion of data-driven and mechanism model, uses the operation data from the SCADA of heating grid to learn and optimize the parameters of the prior knowledge model through a variety of machine learning algorithms, and finally establishes the hydraulic analysis model matching with the real heating grid. This method can be used for the structural optimization, transformation and economy of the heating network of thermal enterprises Provide technical reference for operation.
