220kV 大型变电所电气主接线方案与设备布置初步设计.doc

deployment requirements, vigorously strengthen the party's ideological and political construction, strong regulation" four winds ", the ideological and political quality of party members and cadres has a new improved. But also to see, some members cadres belief not really letter, and slim not really repair, not understand Marx doctrine principle, not learning party of innovation theory, not believes in party of political advocates; some members cadres party of consciousness and members consciousness desalination, in party not statements party, and not love party, and not nursing party, and not for party; some members cadres political discipline, and political rules relaxation, mouth no shoot, mess assessment jump on the party of policies and so on. Solve the problem of party members and cadres ideologically, must start with the ideological and political construction, through the "two" learning education into ideological and political work in day-to-day political life of the party, do fine catch, catch, catch a long, continuous force for a long time to work. 3. "two" education is condensed power development needs. With the deepening of reform and the full implementation of the rule of law, we are building "Qiang Fu MGM" an important task of the new XXX, which we need to rally the wisdom in all aspects, form a partnership to promote the development of a strong force. So, grass-roots party and general members to deep awareness "two learn a do" learning education of important meaning, effective activated grass-roots party fighting fortress role, full play members pioneer model role, in full district development strategy practice in the dang good vanguard, and led bar-headed geese, build a support has iron general belief, and iron general faith, and iron general discipline, and iron General play of members cadres team, for full district work provides strong political, and thought and organization based. 4. "two" learning education is to enhance the ability of party members and cadres needed. The current, complex and volatile state of the world of the party, our party is facing unprecedented difficulties and challenges since the ruling, but also shoulders an important responsibility of politics, society, history, more urgent goal of realizing the great rejuvenation of the Chinese nation. Specific to our personal, minority party members love to party, party, party, retaining the consciousness of the party still needs to be strengthened to work and conscientiousness, initiatives still need to be enhanced, capacity level needs to be further enhanced. Our party . Create "two learn a do" learning education of strong atmosphere on how carried out "two learn a do" learning education, central programme and also issued has learning education programme, Central Organization Department issued has learning education of programme, province, and municipal issued has implementation programme, for all members and at level above leaders of learning education, respectively proposed has different requirements, district also specifically developed has "1+2+4+1" of implementation programme, respectively clear has learning of main content, and Focus on ways and means of solving problems and learning. We want to seriously implement the Central and provincial, city and district of deployment requirements, as more strict and more practical spirit grasp this work. Innovative ways of learning, and earnestly study and understand. To always put learn Constitution Party rules, and learn series speech as "two learn a do" learning education of heavy in the of heavy,220kV 大型变电所电气主接线方案与设备布置初步设计through concentrated learn, and topic learn, and research learn, variety way, strengthened daily learning; carried out "learn Constitution, keep party rules" hundred day copy Constitution activities, do precision learning, insisted article-by-article step, and combines a, and station high telescope, in read original, and learn original, and Wu principle in the guben culture Yuan, complement "spirit of calcium", strengthening "belief of repair", cast "faith of soul". To looks at Yu party and national career of new development on members of new requirements, seriously organization members leaders topic democratic life, and branch topic organised will, further "mirror, and are dressed, and wash bath, and rule cure", self control party cultivation high not high, normal of carried out "three will a class", activities, further deep understanding "to who, and relies on who, and I is who", self review members consciousness strong not strong, timely error correction correction, effective do learn deep Wu through, and really understand really with. Second highlight-oriented learning, and earnestly oath State line. Any members of the party spirit, consciousness and moral level, neither with the accumulation of standing nor with his promotion of natural increase requires transforming the subjective world, strengthen character mold to establish firm ideals and convictions. Therefore, adhering to problem-oriented, problem-solving is "two" learning the internal requirements. In recent years, through the educational practice of the mass line of the party, "three-three" thematic educational activities, quality of party members and cadres in our region as a whole has improved, spirit has been changed, but there are still some outstanding issues and problems. Like part rural members discipline legal consciousness not strong, masses concept weak, pioneer model role play not obviously, on grass-roots democracy construction, and public affairs indifference, and not as, cannot consciously boycott yellow bet HIV against, entertainment activities not health not civilization, minority party fighting fortress role play not obviously, "three will a class", party political life, and "four on the two public", village level democratic decision enough serious specification, highlight problem, to effective do side learn side check side modified, and State said State line State modified, Excited in learning education in the party undertaking, energetic and enterprising spirit, into promoting reform and development, construction of "Qiang Fu MGM" engines of the new XXX. Three actual learning, focus on service work. Currently, we are in a period of reform and development of opportunities; construction of "Qiang Fu MGM" XXX is the new main . Party members perplexity and concern. Rich give a Party lecture form, encourage experiential party lecture, live party lecture, interview-style party lecture, using typical, positive and negative side, strengthening the attraction and appeal of party lecture. "71", each branch in conjunction with the beginning of the 95 anniversary activities, focused schedule 1 party lecture. Third branch of the Organization will be held. The full experience of educational practice using the mass line, "three-three" thematic education held a special democratic meeting and the Organization's practices, picked up the weapons of criticism and self-effectively to solve problems, promote unity and purpose. Four are conscientiously carrying out the democratic review. Combined thematic Organization一、毕业设计（论文）任务课题内容地区变电所是整个电力系统的中间环节，其地位相当重要。目前我国电力系统中的 220kV 变电所一般属于地区型变电所。根据所给定的设计资料对一个 220kV 大型地区变电所的电气部分进行初步设计，包括：通过比较确定电气主接线；确定主变压器的台数、容量和型式；确定所用电接线、所用变压器的台数、容量和型式；确定各电压级的配电装置型式；确定电压互感器和电流互感器的配置；选择各电压级各主要电气设备；进行继电保护配置和防雷规划设计。设计要求：按学校规定的格式要求撰写论文或说明书，并绘制指定图纸。课题任务要求1熟悉变电所电气一次部分初步设计的范围和步骤，掌握工程设计方法，树立工程设计理念；2熟练掌握 AutoCAD 绘图软件；3根据原始资料，通过相应的分析和计算，拟定电气主接线方案，选择主变压器的台数、容量和型式，选择各电压级各主要电气设备，进行电压互感器和电流互感器的配置，确定各电压级的配电装置型式，完成设备布置和初步的继电保护配置和防雷规划设计；4完成毕业设计论文的写作和图纸绘制；5总结课题，并通过毕业论文答辩。课题完成后应提交的资料（或图表、设计图纸）1毕业设计论文及相关图纸；2英文翻译内容：原文和译文；3学校要求提交的其他设计文件和材料。主要参考文献与外文翻译文件（由指导教师选定）1 范锡普. 发电厂电气部分M，中国电力出版社，1992，102-129，168-206.2 西北电力设计院.电力工程设计手册M，上海科学技术出版社，1972,53-88,255-279.3 西北电力设计院. 电力工程电气设计手册（电气一次部分）M，中国电力出版社，1987,45-62,119-123,214-260.4 西北电力设计院. 电力工程电气设备手册M，中国电力出版社，1990.5 黄纯华. 发电厂电气部分课程设计参考资料M，中国电力出版社，1987.6 丁毓山. 变电所设计M，辽宁科学技术出版社，1993.7 郭启全.
