【Abstract】 With DSP TMS320VC33 as its core,a protective device for high-voltage transmission line is developed. The configuration and principle of protective functions,such as directional pilot protection and distance protection,are introduced. The protection software is developed based on relay functional modules and consists of main program and timing interruption program. Module functions of the timing interruption program are described. The device has been fully tested and can be applied in practice.更多还原
