In order to identify the power-on/power-off/grounding state and achieve rapid calculation in the traction power supply real-time monitoring system,the bionic tracing algorithm is proposed by simulating intelligent biological properties.The topology connectivity model is established on the basis of the network topology graph matrix.Marking and tracing techniques are applied in algorithm implementation,and related calculation formulas are derived.Numerical experiments are carried out with an actual traction power supply system.By defining the calculation factor,the efficiency of the bionic tracing algorithm and power algorithm is compared and analyzed,and the results have shown that the bionic tracing algorithm converges faster than the power algorithm,and its calculating speed increases by about 50%.The bionic tracing algorithm has been running as a core module of the traction power supply monitoring system to apply to engineer projects.
