The calculation shows that the attenuation of hydraulics oscillation relates to power, but other kinetic characteristics don ' t change with work point greatly
通過計算表明,其水力振蕩衰減速度與出力有關,而系統的其他運動特性隨工況變化較小。754 horizontal - component digital broad - band records in western north america are processed. the acceleration response spectra are calculated and used as part of the database. the response spectrum values are estimated by the earthquake magnitude definition and are used as another part of the database
將美國西部地區作為參考地區,對美國南加州地區的數字寬頻帶記錄進行了搜集與處理後作為觀測資料,共754條水平向記錄,與利用震級定義所估計的反應譜值一起,用統計回歸的方法建立美國西部長周期加速度反應譜衰減關系。High speed, high damping factor, with reduce / gain, full protect system, special heat radiator, excellent components. it can work at 2, 4, 8
本機其特性為高速度、高阻尼系數、帶衰減/增益切換等等功能、完整的保護系統,獨特的散熱設計,精良的元件,可輕松承受2 4 6 8負載。The recursive criterion of transient current protection based on mallat wavelet transform is presented in order to meet the real - time demands. the reserch shows deficiency existed in the prevenient principle of transient current protection, so a new improved scheme of transient current protection is proposed. the characteristics of transient protection at different bus distribution capacitance is also analysed in this thesis. the study shows that operate of transient protection is correct when the bus distribution capacitance change. other conclusion include : the trip of transient protection must be locked when the power circuit breaker of transimission line operated, because the trip is incorrect at this time ; the features of transient current and it ' s energy is different between the fault and thunder over - voltage in transimission line, and them can be identified ; the ratio of high frequency component of current in serise capaciters compensation line, svc and hvdc system is far little than fault transient current, so all of them do not affect the working of trasient current protection
應用功率譜估計方法討論了故障高頻暫態噪聲信號在頻率軸上的分佈情況,利用功率譜分析結果實現的非參數化系統辨識方法研究了母線分佈電容對電流高頻暫態信號的衰減特性。論文的後半部分(第五,六,七章)著重分析了現有基於故障電流的暫態保護原理和判據存在的問題,提出了新的實現方案,並討論了暫態電流保護的運行性能。利用多分辨分析和小波分解快速演算法構成的遞推暫態保護判據,可以準確區分故障線路和非故障線路,實現超高速暫態電流保護,計算更為簡單方便,計算速度更快。According to the electromagnetic induction theory, abrupt variation of current in the transmitter loop will induce magnetic field around it, which is called the first field. in the transmission of the first field, when it meets good conductor target, induce current will be created, which is called erratic current of second current. because the second current changes with time, so it will create new magnetic field, which is called
對于接收部分,由於瞬變信號具有早期信號幅度大、衰減快,而中晚期信號幅度小、衰減慢的大動態范圍的特點,必須設計適應這種大動態范圍信號的採集電路;為了適應野外工作,系統主控部分採用具有功耗低、高速處理的dsp ,通過高速通用串列介面usb與上位機通訊,實現對整個探測系統的控制。The surplus transient energy, ( ste ), produced during the fault period is used as the quantity index to evaluate the damage degree of generator stability. the effect of gahc to the generator stability was analyzed in single machine system and multi - machine system. the results of analysis show that ste could be reduced by the gahc, the ste decrease of controlled generator would be helpful to reduce the coupled disturbance transient energy of other generators in multi - machine system
以發電機在故障期間積累的過剩暫態能量作為發電機穩定性受到危害程度的定量評價指標,在單機無窮大系統和多機系統中對gahc提高發電機穩定性的作用機理進行了理論分析,分析結果表明: gahc能夠加速被控機組過剩暫態能量的衰減,在多機系統中被控發電機過剩暫態能量的衰減將減少與之關聯的其它發電機受到的耦合暫態勢能的擾動量,也就說明在多機系統中gahc在提高本地機組穩定性的同時不會對其它發電機的穩定性產生危害作用。分享友人
