頻偏指數
英文
frequency deviation index-
The way of taking one nth out of capacitor ' s the first harmonic capacitive reactance as its nth harmonic impedance is verified whit the data from tang7c. according to the approximately estimating method, the first harmonic impedance of 220kv system is calculated. on the basis of the models, this paper gives the harmonic equivalent circuit of substation and gives the b ( n ) function of the harmonic time n. when the capacitors has different combination, b ( n ) ' s value will also change, with the inputting local measurement data, the paper studies the series and parallel resonance at the substation, and deduces that the reason the capacitor ' s fuse of tang6c is frequently interrupted is that its capacitor current contains a large number of 5th harmonics, and that the reason the discharging pt of tang7c capacitor being exploded is also that the 7th and 9th harmonic currents are amplified
據此，對該站進行了串聯諧振分析和並聯諧振分析，並結合測試數據和有關變電站的運行記錄，指出了導致該站電容器湯6c頻繁燒保險的主要原因是5次諧波電流含量偏高，引起湯7c放電pt爆炸也是因為7次和9次諧波電流被放大。針對這些導致湯陰變電站補償電容器故障的原因，提出了相應的諧波治理措施，包括針對湯6c電容器5次諧波電流含量偏高的原因，提出了停運湯6c電容器或者通過把湯sc電容器的部分容量併入湯6c電容器（湯sc其餘部分停運）以增加湯6c諧波承受能力的措施;針對# 2變低壓側7次和9次諧波電流被放大的現象，提出了在湯7c電容器上加裝一定百分比的串聯電抗器的措施。The new measures are a function of the genetic distance between the marker locus and a qtl. through simulations, we found that when marker allele frequencies vary across loci, the previous hwd measures are biased and not powe
計算機模擬表明，當各標記基因頻率不同時，用以前的hwd指數精細定位會產生偏差，新的指數可以有效的進行精細定位，使用y > u和y < t的樣本的lcd的功效普遍比僅僅使用y > u的樣本的氣回，的功效高。It is shown by structural seismic response of four wavelets that littlewood - paley wavelet is not suitable for structural seismic response, because structural response is too small, meyer wavelet is a better wavelet for structural seismic response, for it ' s structural response is agreement with the finite element method, and also harmonic wavelet, structural response under earthquake is a little bigger than finite element method, structural response under odd exponent wavelet is also bigger than finite element method, this method is very simple by wavelet transform, wavelet transform method is different from old methods, one is with which not only knows the effects of earthquake wave detail frequency - band on structural response, but also considers earthquake wave ' s non - stationary of frequency and time - domain value, another is the second mode shape and higher mode shape response that do n ' t attenuate so fast
通過對這四種小波的結構地震反應分析研究說明： littlewood ? paley小波不適合於用來作結構地震反應分析，因為在littlewood ? paley小波下的結構地震反應太小，不符合實際情況；用meyer小波作結構地震反應分析比較合適，和有限元法的結果比較接近；也可以用諧波小波來作結構地震反應分析，只是在諧波小波下的結果略為偏大；單邊指數小波下的結構地震反應分析比有限元法稍大一點，它通過小波變換大大簡化了結構地震反應分析。用小波變換方法來進行結構地震反應分析和以往方法不同的是：它不僅可以知道地震波的具體頻率段對結構反應的影響，而且同時考慮了地震波的幅值非平穩性以及頻率非平穩性；另外與以前方法得到的結果有差異的是，第二振型及以後的高一點的振型的反應沒有以前的方法衰減得快。Through the help of scientific machine detecting, we find out she has the genital weakness in her left kidney meridian system, heart weakness, normal pressure, and liver cirrhosis
經能量醫學儀器檢測，發現為左腎經絡系統先天不足，心系統偏弱，壓力指數尚可，肝硬化的能量頻譜。Some modulation parameters, such as the carrier frequency and the symbol rate, can be estimated prior to the recognition of modulation types. such other parameters as the modulation index, the modulation frequency deviation, and the signal broadband can be further estimated after recognition
部分調制參數如載波頻率、符號速率在識別之前獲得，在識別完成之後可以進一步估計調制指數、調制頻偏、信號帶寬等其餘參數。To reduce the frequency of updates, we can send an update only when the original path and the replicated path diverge by a defined amount ( figure 1 ) ( it may then be necessary to run both the master entity and the replicate by the master process to compare them )
為了降低更新的頻率，我們可以只在原始路徑和復制體的移動路徑發生指定數量的偏離時才發送更新包（這可能需要在主處理器上同時運行主實體和其復制體的運動模擬，以用來對這兩條路徑進行比較） 。To research the issues measurement models and analysis methods of power quality, we put forward an analytical opinion in this paper. following fluctuation of power system, which amends parameters deviation in accordance with fundamental component
本文通過對電能質量的指標、測量模型以及各種電能質量分析方法的深入研究，提出了一種實時跟蹤電壓基波分量參數的變化，獲取幅值、頻率、相角的實時數據，修正偏差的分析思路。分享友人
