    節能熱水器是創新一代熱水設備,它成功地運用卡諾原理,用電能驅動熱泵,通過熱泵裝置中的構成部件-蒸發器,熱泵,冷凝器和膨脹閥,促使工質不斷完成蒸發(吸收空中的熱量)壓縮冷凝節蒸發的熱力循環過程,從而環境的熱量移到水中,將空中大量免費的熱量移到生活中水中
  2. The second chapter simply introduces the development of alternate asynchronous inverter technology and retrospects some types of energy - saving systems for hydraulic elevators. then the working principles of the project are discussed and analyzed at four different working status, i. e. light load upwards, heavy load upwards, light load downwards and heavy load downwards. and the chapter focus on the introduction of structure design of pump station, calculation and type selection of pump / motor reversible units, research on oil leakage principles of accumulator circuit, design of accumulator - pump / motor pressure - energy transformer and integrated valve blocks, etc. the last but not the least, the electrical wiring of vector inverter control cabin and design of computer control and data acquisition system are introduced

    論文第二章首先簡單介紹了交異步電動機變頻調速技術的發展概況,在回顧電梯液壓控制系統節能技術的基礎上,介紹了本課題研製的「採用蓄能器的液壓電梯變頻節能控制系統研究」的基本原理,分析了動力系統在電梯轎廂輕載上下行、重載上下行等四種典型工況下的基本工作狀態和工作方式;詳細地介紹了本課題節能系統液壓動力泵站的結構設計和參數設計,重點研究了液壓動力泵站的結構設計、液壓泵馬達可性問題及其選型設計計算、蓄能器迴路泄漏油損失機理的研究及其補償裝置的設計、蓄能器-泵馬達壓力能量換裝置的設計、多功能集成控制閥組的設計等內容;最後簡單介紹了本課題矢量控制變頻控制櫃的外部附件電接線、計算機控制及數據採集系統的硬體設計等內容。
  3. On the contrary, because of the effect of positive damping provided by the inverter, the unit near a inveter will have no subsynchronous oscillation risk. based on the same method described above, a damping study is carried out for a hybrid ac / dc system, which include a hvdc link and an ac transmission line in parallel

    研究表明,系統整站附近的同步發電機組要承受電負阻尼作用,因此有可能引起機組低頻扭振蕩模式失穩;而hvdc的變站向其臨近同步發電機組提供正阻尼,因而機組不存在次同步振蕩危險。
