Traction substation power signal characteristics and transient power quality evaluation method |
Abstract | ||
|---|---|---|
The electric locomotive operation leads to complex nonlinear dynamic characteristics of the power signal of the traction substation, which makes the calculation of the power quality index based on the steady state signal processing technology have large errors. Therefore, based on power systems computer aided design/electromagnetic transients including DC (PSCAD/EMTDC), the simulation model of common electric locomotive converter is built. The characteristics of traction substation power signal are analyzed and compared with the measured power signal. The internal relationship between the line impedance change of traction electric multiple units (EMU) and grid signal fluctuation is analyzed. Finally, some transient power quality evaluation methods are proposed, and the instantaneous normalized distortion energy index (INDEI) is used to evaluate the transient power quality of the measured power signals. This index can accurately identify the signal jumping type and help to improve the reliability of dynamic load power quality analysis. |
