摘要
随着我国电网容量的迅速增加和电压等级的不断提高,对超高压输电线路保护系统的性能提出了更高的要求。该保护系统以TMS320F2812为核心硬件平台,设有电流差动保护为主体的快速主保护,由工频变化量阻抗元件构成的快速Ⅰ段距离保护,相对于传统的线路保护系统在功能上有了较大的扩展。
As the electric power systems in China become larger and larger,the requirments for their protective relaying are stricter than other protection. The UHV transmission line protection system based on TMS320F2812 chips, the main protection consisting of differential overcurrent relay, one fast zone DPFC distance relay. Cmpared to conventional protection device, the UHV transmission line protection system has extended much in function.
