Transformation scheme of power supply system for wulan coal mine 烏蘭煤礦供電系統(tǒng)的改造方案
They are conflict . in order to resolve the problem , this thesis putforward a new scheme of power supply by special ct with compensate function . analyzed the principle , and designed the structure . in order to reduce the start - upcurrent , there are some devices optimize for the circuit 為了協(xié)調(diào)兩者的矛盾,本文提出了一種帶有補(bǔ)償功能的特制小ct供能方案,對(duì)其基本結(jié)構(gòu)和工作原理進(jìn)行了分析,針對(duì)線路處于小電流工況,設(shè)計(jì)中采用多種優(yōu)化以盡量降低電源的啟動(dòng)線路電流。
The purpose of the thesis is to develop a new type of intelligent high - power ultrasonic power supply , which has many excellent performances . it includes : ( 1 ) the article firstly analyses the electrical impedance and working characteristics of ultrasonic vibration system . based on these , the overall scheme of power supply has been set up and operational principle of control systems has been proposed 本文旨在研制一種多方面性能優(yōu)越的新一代智能化大功率超聲電源,內(nèi)容包括: ( 1 )在分析超聲振動(dòng)系統(tǒng)的電聲特性和工作特性的基礎(chǔ)上,構(gòu)造了智能化超聲電源總體設(shè)計(jì)方案,提出了控制系統(tǒng)的工作原理。
So there are enormous social and economic meaning to make scientific power supply capability evaluation for urban power distribution network base on the role of power supply capability evaluation for urban power distribution network , and current technical level , we put forward a design scheme of power supply capability evaluation for urban network 本文根據(jù)城市電網(wǎng)供電能力評(píng)估的任務(wù),并考慮現(xiàn)有的技術(shù)水平,提出了一種城市電網(wǎng)供電能力評(píng)估軟件的設(shè)計(jì)方案,其中還對(duì)城市電網(wǎng)中輻射網(wǎng)絡(luò)的潮流計(jì)算和可靠性分析方法進(jìn)行了深入研究。
The network scheme of power supply section , the hardware and software environment of this system and the database access mode are introduced briefly . besides , it discuss the method of gis and multimedia for pushing to deal with an emergency , aimed at the approach of video data management . the idea of video database is brought in the management of the video data in this system , and the segmentation and indexing are implemented using simple method 敘述了系統(tǒng)概要設(shè)計(jì)的方法步驟,尤其是由數(shù)據(jù)流圖到軟件結(jié)構(gòu)圖的轉(zhuǎn)化過(guò)程;介紹了幾個(gè)主要功能的實(shí)現(xiàn)方案和數(shù)據(jù)推送技術(shù);簡(jiǎn)單介紹了供電段的網(wǎng)絡(luò)建設(shè)方案、系統(tǒng)軟硬件環(huán)境的選擇和數(shù)據(jù)庫(kù)訪問(wèn)模式的選擇;闡述了事故搶修智能支持的gis解決方案和多媒體解決方案,并著重闡述了視頻數(shù)據(jù)管理的實(shí)現(xiàn)方法;在視頻數(shù)據(jù)管理中成功引入了視頻數(shù)據(jù)庫(kù)思想,用簡(jiǎn)單實(shí)用的辦法實(shí)現(xiàn)了視頻數(shù)據(jù)的分段和檢索。
Then the high potential circuit power supply of ect is reasearched , designed a scheme of power supply by laser , introduced the key part , and reasearchedthe circuit of protecting . the emphases of researchis the scheme of power supply by aspecial ct , but this scheme have two difficult , in the condition of low current inline , the device must work normally 然后對(duì)有源型ect的供能電路進(jìn)行了研究,設(shè)計(jì)了激光供能的整體方案,對(duì)其中關(guān)鍵器件和保護(hù)電路進(jìn)行了介紹和研究。本文重點(diǎn)研究了小ct供能這一在線供能方式,此方式有兩個(gè)難點(diǎn),其一:當(dāng)線路電流處于小電流狀態(tài)時(shí),要保證電源的供應(yīng)。
