| Abstract: |
| Along with the enhanced demand of user and the development of electric power system,the higher reliability of microprocessor based protection is required.The main theories and principles involved in the reliability design of protection are discussed.The reliability design and measures of some typical parts,such as power supply and digital signal buses,are explained with examples.Moreover,some problems that have to be solved urgently in protection reliability research are given.It will not only improve the reliability of protection,but also increase its adaptability to the power system development and change. |
