摘要:本設(shè)計(jì)是水電廠電氣部分設(shè)計(jì)。該水電廠設(shè)計(jì)水頭6.1m,最大水頭10.0m,最小水頭3.0m,設(shè)計(jì)流量390。開(kāi)發(fā)方式為壩后式,裝機(jī)容量為20MW,發(fā)電機(jī)組2臺(tái)。高壓側(cè)為110Kv,一回出線(xiàn)與系統(tǒng)相連,其最大輸送功率為50MW,該電廠的廠用電率為0.6%。設(shè)計(jì)年利用小時(shí)數(shù)為5000小時(shí),年發(fā)電量接近1億度.根據(jù)一次部分的參數(shù),在對(duì)水電廠一次系統(tǒng)分析的基礎(chǔ)上,對(duì)水電廠的配電裝置布置、防雷保護(hù)、繼電保護(hù)做初步簡(jiǎn)單的設(shè)計(jì)。 畢業(yè)設(shè)計(jì)的過(guò)程是一次將理論與實(shí)際相結(jié)合的初步過(guò)程,起到學(xué)以致用,鞏固和加深對(duì)電氣工程及其自動(dòng)化專(zhuān)業(yè)的理解,樹(shù)立工程設(shè)計(jì)的觀念,提高電力系統(tǒng)設(shè)計(jì)能力的作用。 關(guān)鍵詞:配電裝置布置;防雷保護(hù);繼電保護(hù)
Abstract"This design is part of the design of electrical hydropower plants. The hydropower plant design head 6.1m, maximum head of 10.0m, minimum head 3.0m, design flow 390. Development methods for the dam toe, installed capacity of 20MW, 2 sets of generators. High side for the 110Kv, a return outlet connected to the system, the maximum transmission power of 50MW, the plant's auxiliary power consumption rate of 0.6%. Designed annual utilization hours is 5,000 hours, annual power output close to 1 million degrees. According to the first part of the parameters, a system of hydropower plant based on the analysis of hydropower's distribution equipment layout, lightning protection, following the Power protection with a simple preliminary design. Graduation is a process designed to combine theory with practice, the initial process of play apply their knowledge to consolidate and deepen the electrical engineering and automation of the understanding, foster the concept of engineering design to improve the role of power system design capability. Key words: Switchyard; lightning protection; relay
電力工業(yè)是國(guó)民經(jīng)濟(jì)發(fā)展中最重要的基礎(chǔ)能源產(chǎn)業(yè),是國(guó)民經(jīng)濟(jì)的第一基礎(chǔ)產(chǎn)業(yè),是關(guān)系國(guó)計(jì)民生的基礎(chǔ)產(chǎn)業(yè),是世界各國(guó)經(jīng)濟(jì)發(fā)展戰(zhàn)略中的優(yōu)先發(fā)展重點(diǎn)。作為一種先進(jìn)的生產(chǎn)力和基礎(chǔ)產(chǎn)業(yè),電力行業(yè)對(duì)促進(jìn)國(guó)民經(jīng)濟(jì)的發(fā)展和社會(huì)進(jìn)步起到了重要作用。與社會(huì)經(jīng)濟(jì)和社會(huì)發(fā)展有著十分密切的關(guān)系,它不僅是關(guān)系國(guó)家經(jīng)濟(jì)安全的戰(zhàn)略大問(wèn)題,而且與人們的日常生活、社會(huì)穩(wěn)定密切相關(guān)。隨著中國(guó)經(jīng)濟(jì)的發(fā)展,對(duì)電的需求量不斷擴(kuò)大,電力銷(xiāo)售市場(chǎng)的擴(kuò)大又刺激了整個(gè)電力生產(chǎn)的發(fā)展。 隨著我國(guó)經(jīng)濟(jì)的不斷發(fā)展,對(duì)能源的需求量越來(lái)越大,然而能源的不足與需求之間的矛盾在近幾年不斷惡化,國(guó)家急需電力事業(yè)的發(fā)展,為我國(guó)經(jīng)濟(jì)的發(fā)展提供保障。就我國(guó)目前的電力能源結(jié)構(gòu)來(lái)看,我國(guó)主要是以火電為主,但是火電由于運(yùn)行過(guò)程中污染大,在煤炭?jī)r(jià)格高漲的今天,火電的運(yùn)行成本也較高,受鍋爐和其他火電廠用電設(shè)備的影響,其資源利用率較低,一般熱效率只有30%-50%左右。與之相比水電就有很多明顯的優(yōu)勢(shì)。因此,關(guān)于電力系統(tǒng)水電廠設(shè)計(jì)方面的論文研究就顯得格外重要。
