The invention discloses an optimized passing method for a train with vehicle-mounted energy storage in a complex mountain railway. The method comprises the following steps: acquiring train data and parking target points; according to the train data and a parking target point in the front, adopting a maximum potential energy method to calculate and update a train running speed curve; according to the train data and a parking target point in the back, calculating and updating a train running speed curve through a slope rushing reverse running method; outputting the updated train running speed curve, and controlling the train to run according to the curve; and feeding back that the train-mounted stored energy cannot support the train to arrive at the parking target points, and starting rescue measures. The maximum potential energy is fully utilized, the train is allowed to run inertly at the speed exceeding the target speed, and the emergency self-walking capacity is improved; the potential energy conversion of reverse running of the slope rushing is fully utilized, the valley bottom parking phenomenon is avoided, and the train starting difficulty is lowered.
Description
technical field [0001] The invention relates to the technical field of train emergency guidance, in particular to an optimized passage method for trains with on-board energy storage on complex mountainous railways. Background technique [0002] As people's daily travel needs are getting higher and higher, the rail transit industry has been greatly developed, and domestic high-speed railways are spread all over the country. However, due to my country's vast territory and complex mountainous line conditions, various reasons such as bad weather, high-voltage cable shedding, catenary failure, power supply system failure and other reasons will cause power outages in the power grid and loss of train power. At this time, the train can only rely on on-board energy storage The device is powered. However, the space of the train is limited, and the volume and weight of the on-board energy storage equipment are limited. The capacity of the on-board energy storage equipment is very limit...
