Embodiment Construction
[0031] The present application will be further described below through specific embodiments and in conjunction with the accompanying drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other implementation manners obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present application.
[0032]The core of this application is to provide a locomotive automatic over-phase separation control method and device, so that the locomotive unloads power and disconnects the main circuit breaker at a more appropriate time before passing the phase separation, and closes the main circuit breaker at a more appropriate time after passing the phase separation , load power, thereby shortening the power-off time of the locomotive, ensuring that the locomotive passes through the phase ...

The invention relates to a locomotive automatic neutral section passing method and device, belongs to the technical field of locomotive control, can effectively reduce the power loss time of the locomotive in the neutral section passing process, prevents double-bow operation from passing through neutral section, and is simple and reliable in control principle and easy to implement. According to the technical scheme, a locomotive pantograph signal, a locomotive speed signal, a locomotive power signal and a network voltage signal are integrated as a control basis to adjust the output time of each control signal in the automatic neutral section passing process of the locomotive, and before the locomotive enters neutral section, the pantograph signal is combined with the locomotive speed signal and the locomotive power signal to adjust the locomotive unloading power and the main circuit breaker breaking time; after neutral section passing, the network voltage signal is used as a basis forcontrolling the locomotive to close a main circuit breaker and load locomotive power, the pantograph signal is judged before the locomotive passes through neutral section, and if the locomotive runs in a double-pantograph mode, one pantograph is immediately forced to descend, so that only one pantograph is kept running.
Description
technical field [0001] The application belongs to the technical field of locomotive control, and relates to a control method and device in the process of automatic phase separation of a locomotive. Background technique [0002] The locomotive obtains electric energy from the catenary through the pantograph. The catenary usually uses single-phase AC power supply. In order to balance the three-phase load of the power system, the catenary will change phases for power supply at intervals. Short circuit, there is an insulating area at its junction, which is called phase separation. Before the locomotive enters the phase separation, it is required to gradually unload the power to zero and open the main circuit breaker, and coast in a power-off state. After passing the phase separation, close the main circuit breaker to restore power supply and gradually restore power. The locomotive automatic phase separation control system is to use automatic control technology to realize the au...
