Description
Technical Field
The invention relates to the technical field of pantographs of electric locomotives and motor cars, in particular to a pantograph active control method and a pantograph active control device based on current taking feedback.
Background
In electrified railways and urban rail transit systems, electric trains use pantographs to draw electrical energy from overhead contact systems. The pantograph generally comprises a pantograph slide plate, an upper frame, a lower arm rod (a lower frame for a double-arm pantograph), a bottom frame, a pantograph lifting spring, a transmission cylinder, a supporting insulator and the like.
The pantograph is installed at the top of the carriage, and the pantograph slide plate is kept in sliding contact with a contact wire for providing electric energy in the running process of the train. The two subsystems of the pantograph and the catenary are coupled together through the contact force of the pantograph and the catenary to form an interactive dynamic system.
The electrical energy required by the electric train is transmitted through the contact points of the pantograph slide plate and the contact wires. During acceleration, the bowden contact points pass a large current. The large current causes the contact of the pantograph net to ignite an arc, thereby increasing the electrical abrasion of the pantograph slide plate and the contact line. At present, the service life of a plurality of subway pantograph slide plates is only half of the expected value, and the economy is greatly reduced.
Therefore, the invention hopes to achieve the purposes of reducing the arcing phenomenon of the pantograph mesh of the accelerating section and reducing the abrasion of the pantograph slide plate through active control of the pantograph.
The Chinese patent document with the document number of CN106094520A discloses a pantograph active control method based on state feedback accurate linearization. The pantograph control method disclosed by the document is to build a ternary pantograph-catenary coupling dynamics model, perform stress analysis on the model to obtain the state quantity of a pantograph-catenary system, perform feedback linearization on the state quantity, and calculate a transfer function and a zero pole so as to adjust the pantograph lifting force and achieve a linear optimal control strategy.
The Chinese patent document with the document number of CN105652111A discloses a pantograph dynamic operation performance control method and device. The control method for the pantograph mainly comprises the steps of obtaining the current-carrying performance parameters of the pantograph net and the dynamic performance parameters of the pantograph through experiments, then utilizing a quadratic polynomial curve regression method, using a trend regression curve of the contact force of the pantograph net in different opening directions and under different speed levels, and finally controlling the dynamic operation performance of the pantograph through the obtained trend regression curve of the contact force of the pantograph net. The main focus is to control the contact force of the bow net by controlling the dynamic performance parameters of the pantograph, so as to ensure that the bow net receives good current.
The Chinese patent document with the document number of CN2014570094U discloses a pantograph active control device which can actively compensate the contact force change of a contact net due to various factors and reduce pressure fluctuation. The device mainly adopts the working principle that the computer gas circuit controller and the GPS device on the train are used for determining ideal lifting amounts of the pantograph corresponding to each position of an operation interval, and then the total lifting amounts generated in different movement states of the pantograph are calculated according to the data of the vehicle-mounted speedometer and the data of wind power, wind direction and the like obtained by the train anemometer and by combining the rigidity value of the current overhead contact system. And finally, actively performing open loop control on the air bag according to the ideal lifting amount and the total lifting amount to compensate the contact pressure of the bow net, so that the contact pressure is always basically consistent. The main focus is that the data obtained by the device controls the pantograph air bag, thereby controlling the contact pressure of the pantograph net.
At present, active control on the pantograph is realized mostly by adjusting dynamic parameters of the pantograph, and active control is performed according to dynamic performance of the pantograph. But the current-carrying capacity of the contact point of the pantograph net is not considered in the control.
The inventor researches the problem, and the research result shows that when the current-carrying capacity of the contact point of the pantograph and the net is increased, the arcing probability is greatly increased, and the abrasion of the pantograph slide plate and the contact line is further increased. Based on this study, the inventors propose to reduce the arc rate by increasing the static bowing force, thereby reducing bowing net wear to improve this situation.
