Abstract

Abstract: Electric traction locomotive generates a single-phase rectifier load which has the nonlinear, asymmetric and large fluctuation characteristics. The stochastic volatility of the numbers of trains within one feeding section and the running status of each locomotive may result in voltage fluctuation of power grid, which will deteriorate the power supply quality. In view of the traction load characteristics of the Lanzhou-Xinjiang second electric railway, which is large in operation density, high in running speed and short in distance to the nearby wind farms, a model simulation is made by using the power system simulation software, including PSASP and ETAP, to analyze the mechanisms for a series of problems such as voltage and frequency deviation, voltage fluctuation and harmonic waves, with the focus paid to the influence of the integration of the traction substation into the power grid on the wind generator units.

Key words: power grid, power system, traction loads, wind farm, power quality, harmonic, frequency, voltage
