The operational characteristics with the different operational parameters, with different terminal cooling load of air conditioning system, with different heat exchange characteristics between underground u - tube pipe loop and soil, etc. have been studied. the operational characteristics of gshps within starting period, normal period and the period of variable operation patterns under different seasonal conditions has also been studied
研究熱泵機組運行參數變化、空調末端負荷變化和地下埋管換熱器變化時土壤源熱泵系統的運行特性;開展不同季節和不同工況土壤源熱泵的啟動、正常和變工況運行特性的研究。 -
Operation under normal load for a specified period, starting from cold, the intervals after each period of operation being sufficient to allow the equipment to cool down to room temperature
常規負載下特定時間段的一種操作,該時間段從冷態開始,到使設備到達室溫的間隔。 -
Fristly, according to the non - linear characteristics of twelve - phase rectifier, the thesis gives the calculation model for a short circuit in the subway traction power supply networks which provides the academic foundation for the design of the setting values and the simulation of protection. secondly, the thesis designs the dc feeder protection and control of subway, and gives the principle of setting accordingly, after it analysizes the characteristics of electric current under tow load and short circuit and considers severel factors. to validate the rationality of the design, the thesis simulates the transient electric current under two work conditions ( starting and passing the insulation ) ahd short circuit
其次,本文在詳細分析地鐵牽引負荷電流和饋線短路故障電流特點的基礎上,考慮了直流保護系統設計應注意的幾個因素,對地鐵饋線保護與控制進行配置,給出了相應的保護整定原則,並針對某一地鐵供電系統在詳細分析了兩種工況(機車起動與過分段絕緣)的電流暫態過程,得到了電流計算的數字模型,結合前面提出的短路模型,進行了地鐵饋線保護的模擬,經模擬表明本文的保護設計是合理的。
