电力系统规划
摘要
电力自从应用于生产以来,已成为现代生产化、生活的主要能源,在工农业、交通运输、国防、科学技术和人民生活等方面都得到了广泛的应用。电力工业的发展水平和电气化程度是衡量一个的重要标志。
本设计的题目是电力系统规划设计,关于一个具体的电力系统,其性能好坏直接关系的工业生产和人民生活,所以电力系统规划设计,一定要满足三个要求:可靠性、灵活性和经济性。
本设计从对原始资料开始分析,确定其装机容量以及负荷的合理性;到校验有功、无功的平衡;以及对设计出来的方案做初步的比较,接着从技术比较、经济比较对其做出精确的比较,从而确定系统的主接线形式、发电厂的主接线形式;对所确定的接线形式,进行发电厂、变电所容量型号的选择,确定变压器和高压断路器的型号;最后进行短路、潮流和调压计算,校验所选方案、电气设备的可靠性、灵活性。
Power system planning

Abstracts
Since the electricity used in production, it has e a modern production, the main energy of life, industry and agriculture, transportation, defense, science and technology and people's living conditions have been widely used…. The development of electric power industry and the level of electrification is a measure of the level of national economic development an important indicator.
The design is the subject of power system planning and design of a specific power system. its performance is directly related to the industrial production and people's lives, and therefore the power system planning and design, must meet three requirements : reliability, flexibility and economy.
From the design of the original data analysis began to determine the load capacity and reasonable; Check to meritorious Reactive balance; and the design of the program to do the parison, and then from the parison, make the economy more precise, in order to determine the main wiring system forms the main wiring plant forms; Have the right to determine the form of wiring, power plants, substations capacity models of choice, identified transformers and high voltage circuit breaker models; Finally circuit, and the surge tide, check the selected program, Electrical equipment reliability, flexibility.
