| Abstract: | A grey gate fault tree analysis for traction power SCADA system is proposed. The theory of grey gate fault tree is introduced as well as the structure of traction power SCADA system. The fault tree of the traction power SCADA system is established, where fault probabilities are described by probability gray numbers. The events＇ relationships are described by grey gates instead of conventional logic gates. An example of a traction power SCADA system shows that the results using gray gate fault tree analysis are feasible and effective. |
