内容摘要:
本设计根据设计的原始资料及参考书籍,作出了35KV降压变电站继电保护设计。设计说明书内容共分为七章,包括负荷计算,功率补偿与变压器,高压电器选择,短路电流计算,继电保护和防雷措施等。改设计以实际负荷为依据,变电所的最佳运行为基础,按照有关规定和规范,完成了满足改要求的35KV降压变电所继电保护设计。
变电所电力系统中对电能的电压和电流进行变换、集中和分配的场所。为保证电能的质量以及设备的安全,在变电所中还需进行电压调整、潮流控制以及输配电线路和主要电工设备的保护。
继电保护对我国电力系统的安全运行,起着不可替代的作用,在我国经济持续发展,对电力要求不断增大的情况下,要做好继电保护工作,就要从各方面对继电保护的基本任务和意义,以及起保护作用的继电保护装置有深刻的了解,并要及时掌握未来技术发展的方向。

The Design Of 35KV step-down substation relay protection
Abstract :
The design according to the design of the original data and reference books, made a 35KV step-down substation relay protection design. Design specification is divided into seven chapters, including load calculations, pensation and transformers, high voltage electric appliance choice, short-circuit current calculations, relay protection and lightning protection measures. Change the design based on actual load, substation based on the best run in accordance with relevant regulations and norms, pleted the requirements to meet the change 35KV step-down substation relay protection design.
Substation power system voltage and current of electrical energy to transform, focus and allocation of places. To ensure the quality of electricity and equipment safety, the need for the substation voltage regulation, power flow control, and the main electrical transmission and distribution lines and equipment protection.
Protection of the safe operation of power system, plays an irreplaceable role in China's sustained economic development, increasing the power requirements of the case, to do protection work, we should all aspects of the relay Protection of the basic tasks and significance, and the protective relay device has a deep understanding of, and to grasp the future direction of technology development. Key words: 35KV substation relay protection
