The invention relates to the technical field of rail transit, in particular to a self-adaptive anti-sliding control method for an alternating-current transmission locomotive. Comprising the following steps that S1, the average rotating speed of a traction motor is obtained; s2, acquiring information about whether the locomotive has a traction handle or not; if the average rotating speed of the traction motor is lt; if the locomotive is provided with a traction handle, a locomotive sliding control algorithm is triggered, the layer degree of locomotive sliding is divided into different grades, traction braking, electric braking and air braking measures are taken in the different grades, and locomotive sliding is restrained in real time; if the average rotating speed of the traction motor is lt; and if not, triggering a sliding control algorithm, and directly applying an air braking measure according to the average rotating speed threshold value of the traction motor and the acceleration threshold value of the locomotive. According to the scheme, the locomotive sliding is effectively prevented or inhibited, the running reliability of the locomotive is improved to the greatest extent, and the safety risk of railway transportation is reduced.
本发明涉及轨道交通技术领域,具体涉及一种交流传动机车自适应防溜车控制方法。包括以下步骤:S1,获取牵引电机的平均转速;S2,获取机车是否有牵引手柄信息;若牵引电机平均转速<0,且机车有牵引手柄,则触发溜车控制算法,将溜车的层度分为不同等级,并在不同等级内采取牵引制动、电制动和空气制动措施,实现对机车溜车的实时抑制;若牵引电机平均转速<0,且机车无牵引手柄,则触发溜车控制算法,根据牵引电机平均转速阈值和机车的加速度阈值,直接施加空气制动措施。本方案有效防止或抑制机车溜车,最大程度上提高机车运行的可靠性,降低铁路运输的安全风险。
