Abstract

The invention discloses an optimized passage method for trains with vehicle-mounted energy storage on complex mountainous railways, which includes obtaining train data and parking target points; according to the train data and the parking target points in front, using the method of maximizing potential energy to calculate and update Train running speed curve; according to the train data and the rear parking target point, use the slope reverse running method to calculate and update the train running speed curve; output the updated train running speed curve, and control the train running according to the curve; feedback the train on-board The energy storage cannot support the train to reach the parking target point and initiate rescue measures. The invention makes full use of the maximized potential energy, allows the train to run inertly beyond the target speed, and improves the emergency self-propelled ability; fully utilizes the potential energy conversion of the slope and reverse running, avoids the parking phenomenon at the bottom of the valley, and reduces the difficulty of starting the train.

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...
