【摘要】：電力是一個國家最基礎的能源之一,架空輸電線路是電力系統(tǒng)中必不可少的、重要的一個組成部分。隨著輸電線路建設、改造投資的加大,客觀上對線路設計的速度、質量、準確性、經(jīng)濟性、安全性都提出了更高的要求。由于輸電線路設計的技術性和理論要求較高,本文首先介紹了輸電線路設計過程中涉及到的概念、公式與常用的物理參量,并分析了各參量的關系和計算方法。其次,輸電線路設計過程需要查閱和參照大量的數(shù)據(jù),所以著重分析了數(shù)據(jù)庫系統(tǒng)的設計思路和實現(xiàn)方法,并且針對輸電線路設計時最常訪問的基礎數(shù)據(jù)庫與工程數(shù)據(jù)庫給出了數(shù)據(jù)表的構造示例,以最大程度的滿足數(shù)據(jù)庫系統(tǒng)實用性和小冗余性的目標。再次,介于輸電線路設計對輔助設計軟件的極大需求,本文給出了一套合理可行的輔助設計系統(tǒng)架構,介紹了整個系統(tǒng)的體系結構及各模塊的關系,并逐個闡述各模塊的功能和意義,就數(shù)據(jù)表維護、架線桿塔定位、導線力學計算、金具材料統(tǒng)計等最重要的功能展示了設計方法流程,盡可能的給設計者提供更多的便利和更寬泛的思路。對架空輸電線路設計原理的分析的主要目的是為輸電線路計算機輔助設計提供更加實用和完備的理論架構和系統(tǒng)架構,使設計者更加便捷和精確地完成圖形構造、參數(shù)計算、數(shù)據(jù)處理等工作,加快設計進度,提高設計質量,最終適應當前繁重的電網(wǎng)建設形勢。
[Abstract]:Power is one of the most basic energy sources in a country. Overhead transmission line is an essential and important part of power system. With the construction of transmission lines and the increase of investment in transformation, higher requirements for speed, quality, accuracy, economy and safety of line design are put forward objectively. Since the technical and theoretical requirements of transmission line design are high, this paper first introduces the concepts, formulas and common physical parameters involved in the design process of transmission lines, and analyzes the relations and calculation methods of each parameter. Secondly, the transmission line design process needs to consult and refer to a large number of data, so the design ideas and implementation methods of the database system are emphatically analyzed. An example of data table construction is given for the basic database and engineering database which are most frequently visited in the design of transmission lines, so as to meet the objectives of database system practicability and small redundancy as much as possible. Thirdly, in view of the great demand for auxiliary design software in transmission line design, this paper presents a set of reasonable and feasible auxiliary design system architecture, and introduces the architecture of the whole system and the relationship between each module. The functions and significance of each module are expounded one by one, and the design method flow is demonstrated for the most important functions, such as data table maintenance, wire tower positioning, wire mechanics calculation, material statistics of fittings, etc. As much as possible to provide designers with more convenience and broader ideas. The main purpose of the analysis of the design principle of overhead transmission lines is to provide a more practical and complete theoretical framework and system framework for the computer-aided design of transmission lines, so that the designers can complete the graphic construction and parameter calculation more conveniently and accurately. Data processing to speed up the design process, improve design quality, and finally adapt to the current heavy power grid construction situation.
