簡易后備操作器接收從dcs系統或pid調節器給定的模擬量信號,正常控制時,操作器輸入輸出相當于直通的,以實現dcs系統或pid調節器對執行機構的自動控制,當前級dcs系統或pid調節器發生故障時,操作器接收到故障狀態信號,即轉為手動控制狀態,由按鍵控制操作信號的輸出,當故障解除,儀表自動恢復自動狀態。Abstract : the rechargeble batteries are used for backup power internal electrically equipments and instruments. but batteries lifetime usually is shorten by overwork and then malfunctions of equipment are induced. to avoid the complexion described above, the protection circuit against overwork is designed. it is based upon the voltage comparator and regulator. it will light up a red led when the volume of the batteries discharged close upon 50 % ; it will switch off the load automatically when it discharged closing to 80 % of their energy capacity, thus overwork of batteries can be avoided and lifetime may be extended
文摘:用蓄電池做后備電源的系統(或設備) ,常因過放電導致電池提前報廢而造成設備故障.根據電池電壓隨容量變化的規律,利用電壓比較器和電壓基準源設計製作了電池放電保護電路,當電池放電量接近容量的50 %時,啟動預警信號;當電池放電量達到容量的80 %時,電路自動切斷負載,防止電池過度放電,延長電池壽命,保證系統(或設備)在供電恢復正常后能正常運行Fault section identification and isolation of distribution network with reclosers and sectionalizers are also talked about. based on load balancing, the way of optimal restoration is disussed
以安全和負荷均衡分佈為原則,基於等長鄰接表的數據結構,建立了故障隔離后受故障影響的健全區域的優化恢復策略的搜尋方法。In order to strengthen the security and stability of the system, the technology of data interim store is applied. when the database server or application server is out of control, the users can store the updated data into the client computers ; after the database server or application server can work, the users load the data and update into the database
為了加強系統的安全穩固性,採用了暫存數據技術,使系統中當數據厙服務器或應用服務器發生故障時,用戶能夠把更新的數據暫時存儲在客戶端機器中,待數據庫服務器或應用服務器工作恢復正常后,再把數據加載到系統中並更新回數據庫。A service restoration model with priority customers is established too, and the model take the fact of the loads propotion into account
採用考慮用戶優先等級的故障后的恢復模型,在對停電區域恢復供電的時候,考慮配電網路的負荷均衡化。In the main body of this paper, the database design process is introduced, in which the database relation schema, data integrity and fault recovery are emphasized, and, the communication protocol designed for remote data acquisition is discribed and validated by petri nets, the develop method of client application and resolvent to some problems are also discussed, including the design of communication component, the asynchronous data return, how to dynamically return image to the client navigator in web application etc. finally, an abbreviated evaluation about the finished system is given
在論文的主體部分,論文詳細介紹了數據庫的設計過程,其中主要涉及到關系模式的規范化、數據完整性和故障恢復設計等,隨后,文章設計了一種用於遠程數據採集的通信協議,並使用petri網進行了描述和驗證,論文也介紹了如何進行客戶端應用程序的開發以及一些主要問題的解決,主要包括通信控制項的設計、採集數據的異步返回、在web應用程序中如何動態為客戶端返回圖形等。最後,論文對整個系統做了一個簡單的評估。A non - linear feed - forward loop is used to realize the coordinated control between the two controlled variables at the two control ends at first. secondly, a constant ac voltage control is implemented for a short period after the ac fault removal. finally, a staggered recovery strategy for different hvdc subsystems is also adopted, with the restart time interval of them optimized using the steepest descent gradient search method
該協調恢復策略的三個特點是:在常規的控制器結構中加入一個基於準穩態工作點的非線性前饋迴路;在交流故障被切除后的一個短暫時間內,逆變側採用定交流電壓控制:對不同的直流輸電子系統採取一種漸進的恢復策略。The current spic has the functions of under - voltage and over - current checking, which can protect the system by automatically stop working when the system is in trouble until the trouble is eliminated
當前的智能功率集成電路一般都具有欠壓檢測和過流檢測等功能,在系統出現異常時電路會自動停止工作直到故障排除后才恢復正常工作,從而保護系統。In case of complicated dc circuit, any type of symmetrical ac system fault. dc line fault and dc line ' s recovery after fault can be more accurately simulated, and the dc line ' s dynamic response can be better represented. all the above is very important when doing the research on dc power support to ac system under emergency conditions, and has laid a solid foundation for the interaction study which will be met in a hybrid ac / dc power systems
該模型能夠在對交流網路進行機電暫態計算的同時,對直流網路進行電磁暫態的計算,因而能較精確地考察暫態過程中直流線路的動態行為,並可對任意對稱的交流系統故障、直流線路故障以及故障后直流輸電系統的恢復等過程進行模擬,且模擬時間較短,為在復雜系統中研究直流輸電系統與交流輸電系統間的相互作用奠定了基礎。Besed on wavelet " s well localized characterizes in time frequency and space frequency, we can exactly depict events of nonnoise by decomposing to signal using binary - wavelet transform. for events of noise, local max can be found at singular points of signal by using wavelet transform norm of signal, so adopting multiscale wavelet analysis the maximal point of wavelet transform norm, which risen by the noise, with increasing of scale, which rien by the fault appeared. gived a properly threshold and compared the relation of data that have been transformed not only find the fault in the low noise signal but also resume the signal by filtering noise, which have good power of examining singular signal being unexpectedly change
對于噪聲中的事件點,利用信號的小波變換的模在信號的突變點取得局部最大值,採用多尺度(多分辨)小波分析,則隨著尺度的增大,噪聲引起的小波變換模的極大值點迅速減少,而故障引起的小波變換模的極大值點得以顯露,我們給出一個適當的閥值,比較閥值和變換后數據的關系,不但可以在低信噪比的信號中監測到故障信號,而且可以濾去噪聲恢復原信號,對突變的奇異性信號具有良好的監測能力,能夠有效地找出噪聲中的事件點。But it is followed by another problem - because it is very difficult for us to find a correct failure detection in asynchronous system such as the internet, the mobile agent fails and recovers later, they all lead to a violation of the exactly - onc e property for the agent ' s execution
但隨之另一個問題又產生了? ?由於在異步的分散式的網路環境中很難找到一種可靠的故障檢測機制以及陷入故障的移動agent在經過一段時間后又隨時可能恢復正常,所以這都可能會導致對移動agent只執行一次屬性的破壞。A new method for fast recovery after distribution network failure
