[工学]110KV变电站设计最终修改通过版.doc

摘要 随着经济发展和现代工业建设迅速崛起，供电系统的设计日益全面、系统，工厂用电量迅速增长，对电能质量、技术经济状况、供电的可靠性指标也日趋提高，因此对供电设计也有了更高和更完善的要求。设计是否合理，不仅直接影响基建投资、运行费用和有色金属的消耗量，也会反映在供电的可靠性和安全生产方面，它和企业的经济效益、设备人身安全密切相关。 变电站是电力系统的一个重要组成部分，由电器设备及配电网路按照一定的接线方式构成，他从电力系统取得电能，通过其变换、分配、输送与保护等功能，然后将电能安全、可靠、经济地输送到每一个用电设备的转设场所。作为电能传输与控制的枢纽，变电站必须改变传统的设计和控制模式，才能适应现代电力系统、现代工业生产和社会生活的发展趋势。随着计算机技术、现代通讯和网络技术的发展，为目前变电站的监视、控制、保护和计量装置及系统分隔的状态提供了优化组合和系统集成的技术基础。 随着电力技术高新化、复杂化的迅速发展，电力系统在从发电到供电的所有领域中，通过新技术的使用，都在不断地发生变化。变电所作为电力系统中一个关键的环节也同样在新技术领域得到了充分的发展。 关键词：变电站、负荷、输电系统、配电系统、高压网络 Abstract With the development of economy and the rapid rise of modern industrial construction, power supply system design is more comprehensive, systematic, plant fast-growing consumption of electricity, the power quality, technical and economic conditions, the power supply reliability index also increased day by day, so the power supply design have higher and more comprehensive requirements.Whether the design is reasonable, not only directly affects the capital investment, operating costs and the consumption of non-ferrous metals, will be reflected in the power supply reliability and security of production, and the economic benefits of the enterprise, personal safety related equipment. Electric power substation is an important part of the system, from electrical equipment and distribution network according to a certain mode of connection form, he obtained from the energy power system, through its transformation, distribution, transport and protection functions, and then energy safe, reliable, economic delivery to every electrical equipment switch a place.As a hub for power transmission and control, substation must change the traditional design and control mode, to adapt to the modern power systems, modern industrial production and development trend of social life.With the development of computer technology, modern communications and network technology development, for the current substation monitoring, control, protection and measuring devices and systems provide a
