摘要
Abstract
The potential limiting device is adopted widely in the metro on use. The rail voltage in operation always maintains a high value by long time observation, which will result in traction substation OVPD keeping the closed state. This situation leads to the increased of the current leakage, so as to increase the stray current produced harm. Therefore, the optimal control of OVPD will be more effective, the rail potential will be effectively reduced, and the effect of stray current will be weakened. The analyses on rail potential changes are made with OVPD off and on in single interval and multi intervals in two substations. Simulation results verify the reasonability and effectivity of the proposed rail potential limiting device control strategy.关键词
