To make the regulator high operating reliability , the design adopts two - channel architecture i . e . it consists of two completely identical and independent channels 從可靠性角度考慮,本調(diào)節(jié)器采用了雙通道的結(jié)構(gòu),即有兩個硬件完全相同而又相互獨(dú)立的通道構(gòu)成。
The power supply quality and operating reliability and stability of synchronous generator system are influenced directly by performance and operating reliability of excitation system 勵磁系統(tǒng)性能的好壞和運(yùn)行的可靠性,直接影響同步發(fā)電機(jī)系統(tǒng)的供電質(zhì)量及其運(yùn)行的可靠性和穩(wěn)定性。
Abstract : the design features of the fire water system of fenglian plaza building are presented , some measures to improve the problems arisen in the trial - run and acceptation are proposed , and furthermore advances of technical feasibility and operating reliability are discussed 文摘:闡述了豐聯(lián)廣場大廈消防給水設(shè)計(jì)特點(diǎn),并針對驗(yàn)收調(diào)試中遇到的問題提出了改進(jìn)措施,進(jìn)而從技術(shù)可行性、運(yùn)行可靠性幾個方面對改進(jìn)措施進(jìn)行了探討。
The research works are shown mainly as follows : 1 ) the actuality and outlook of on - line detecting and fault diagnosis technology of gases dissolved in oil are analysed deeply , and characteristics of insulation structure of power transformer , evaluation of operating reliability and the relationship between ordinary faults inside transformer and gases dissolved in transformer oil are studied too . analysing the purposes of detecting gases dissolved in transformer oil on - line , we can know that primary indexes to evaluate the technology of on - line detecting gases dissolved in transformer oil are reliability of system , accuracy of detected data , validity of diagnosis , automatization and price of systems 主要研究內(nèi)容有: 1 )深入分析變壓器油中多種溶解氣體在線監(jiān)測及故障診斷技術(shù)研究現(xiàn)狀及應(yīng)用前景,研究電力變壓器絕緣結(jié)構(gòu)特性、運(yùn)行可靠性評估以及變壓器內(nèi)部常見故障與油中溶解氣體對應(yīng)關(guān)系,通過對在線監(jiān)測變壓器油中溶解氣體的目的分析得出系統(tǒng)運(yùn)行的可靠性、監(jiān)測數(shù)據(jù)的正確性、診斷的有效性、系統(tǒng)的自動化程度、系統(tǒng)的價(jià)格等是綜合評價(jià)變壓器油中溶解氣體在線監(jiān)測技術(shù)的指標(biāo)。
Furthermore , this paper provides several forms of failure ratio in the operating phase taking the difference between the testing profile and the operating profile into account according to the concepts of the testing reliability and the operating reliability , then analyzes theoretically the difference between the testing reliability and the operating reliability based on the changing trends that the failure of decreasing and first increasing and the decreasing of the failure ratio , and makes a research on the influence of the two types of reliability on the software releasing time 在此基礎(chǔ)上給出了考慮測試剖面與運(yùn)行剖面差別的幾種運(yùn)行階段失效率的形式,然后根據(jù)失效率遞減的和先增后減的變化趨勢,從理論上分析了測試可靠性與運(yùn)行可靠性的差別,研究這兩種可靠度對軟件發(fā)布時(shí)間的影響。絕大多數(shù)軟件可靠性增長模型都假設(shè)軟件故障服從同一種分布。
