One is the development of reliability evaluation using vb which based on the layer of network and recursive arithmetic 文章重點對配電網(wǎng)的可靠性評估和網(wǎng)絡(luò)重構(gòu)的模型和算法進行了研究。
Then , using recursive arithmetic calculated reliability indices for directory tree , the method was realized by vb program ; the other is a method of reliability evaluation by interval arithmetic , which is the use of interval arithmetic to evaluate reliability , and the computation theory is also given . during the calculation , interval number replaced the component " s parameter and it takes into consideration the uncertainty of all of the parameters . in the study of power distribution system configuration , a new configuration model is set up which takes into account simultaneously the losses minimization and system reliability , then improved genetic arithmetic is described detail and of advantage for solving this problem 在配電網(wǎng)可靠性評估的研究中,提出了兩種實用的配電網(wǎng)可靠性評估方法:其一是利用網(wǎng)絡(luò)分層和遞歸算法理論,使用高級語言進行程序設(shè)計,提出了一種基于vb編程的配電網(wǎng)可靠性評估方法,該方法通過程序?qū)崿F(xiàn)了網(wǎng)絡(luò)拓撲結(jié)構(gòu)的分層等效和可靠性指標(biāo)的遞歸計算,使整個計算過程得到了簡化,并且界面窗口的可視化,使得評估過程便捷、形象;其二是提出了一種基于區(qū)間算法的配電網(wǎng)可靠性評估方法,該方法是一種利用區(qū)間理論計算配電系統(tǒng)可靠性的不確定性評估方法;文章給出了區(qū)間運算的原理;討論了配電系統(tǒng)中區(qū)間數(shù)據(jù)的來源途徑,并用區(qū)間數(shù)代替元件的可靠性參數(shù),對輻射形配電網(wǎng)進行了可靠性評估。
According to the basic mathematical model of the oil / water two - phase profile interpretation based on temperature and flowmeter logs , a similar idea to that of " first getting the retrieve function then the original function " is employed to solve the model . the recursive arithmetic suitable to computer programming has been presented , which make the profile technique available in practical production 本文根據(jù)利用流量、溫度信息確定油水兩相產(chǎn)出剖面的基本數(shù)學(xué)模型,提出了一種類似于函數(shù)論中常常用到的一種求形式復(fù)雜函數(shù)的辦法對模型進行了求解,從這一思想出發(fā),給出了適合計算機程序?qū)崿F(xiàn)的遞推求解算法,并且編制程序?qū)λ惴ㄟM行了實現(xiàn)。
As a important component in cppm - gis , this paper illustrates detailedly the mathematics model of optimum design and direct optimization method for drainage pipe - net under gis . as a key stage in planning and designing the drainage system , the caculation of pipe - net is very critical and time - consuming . this paper brings forward the recursive arithmetic for pipe - net and pipeline designed - discharge 在cppm - gis系統(tǒng)中,水力計算模塊是一個重要的組成部分。本文詳細論述了gis環(huán)境下建立排水管網(wǎng)優(yōu)化設(shè)計的數(shù)學(xué)模型、排水管網(wǎng)的直接優(yōu)化法。
