【摘要】：采用系統(tǒng)工程的方法優(yōu)化熱泵供暖系統(tǒng)操作,實(shí)現(xiàn)節(jié)能運(yùn)行具有重要意義。在建立熱泵供暖系統(tǒng)基本動態(tài)方程的基礎(chǔ)上,給出了考慮室溫控制精度和能耗節(jié)省的優(yōu)化操控目標(biāo),通過聯(lián)立求解方法將原微分代數(shù)方程優(yōu)化問題(DAOPs)轉(zhuǎn)化為非線性規(guī)劃問題,然后對不同目標(biāo)側(cè)重下的動態(tài)操作優(yōu)化問題進(jìn)行了分析,并提出了動態(tài)調(diào)整目標(biāo)函數(shù)權(quán)重的優(yōu)化策略。優(yōu)化計(jì)算結(jié)果表明:在室溫跟蹤誤差最大為0.85℃的情況下系統(tǒng)可實(shí)現(xiàn)16%以上的節(jié)能效果;環(huán)境溫度和電價對系統(tǒng)操作優(yōu)化具有重要影響,根據(jù)兩者的變化特征而動態(tài)調(diào)整目標(biāo)函數(shù)權(quán)重可以進(jìn)一步降低系統(tǒng)能耗4.7%左右。本研究對熱泵供暖系統(tǒng)優(yōu)化節(jié)能控制具有一定的現(xiàn)實(shí)意義。
[Abstract]:It is of great significance to optimize the operation of heat pump heating system and realize energy saving operation by system engineering method. On the basis of establishing the basic dynamic equation of heat pump heating system, the optimal control target considering room temperature control precision and energy saving is given. The original differential algebraic equation optimization problem (DAOPs) is transformed into a nonlinear programming problem by simultaneous solving method. Then the dynamic operation optimization problem with different objectives is analyzed. An optimization strategy is proposed to dynamically adjust the weight of the objective function. The results of optimization calculation show that the energy saving effect of the system can be more than 16% when the maximum tracking error is 0.85 鈩，
