Description

Technical Field

[0001] The present invention relates to the technical field of bilateral power supply for AC electrified railways, and in particular to a vehicle-ground coordinated phase-splitting device and method. Background Art

[0002] The bilateral power supply method can improve the power supply capacity of the traction power supply system to solve the problems of weak external power supply and insufficient power supply capacity of the power system. The bilateral power supply method can also eliminate the phase separation of the substations. Further combined with the same-phase power supply technology, it can achieve full-line through-power supply and eliminate all power-free areas on the line, thereby solving the problems of train speed loss, transient overvoltage, and reduced power supply reliability caused by phase separation under the traditional unilateral power supply method. At present, the research and application of bilateral power supply technology on some lines has begun to be explored.

[0003] However, even if the bilateral power supply method is adopted, electrical segments still need to be set between different power supply arms to divide the power supply units, so as to improve the flexibility of power supply and effectively reduce the impact range of the fault section. When the power grid fails or other special circumstances occur, the traction power supply system needs to be decoupled from the bilateral power supply method to the unilateral power supply method, and the electrical segmentation needs to be converted to electrical phase separation to achieve electrical isolation between different power supply arms. Accordingly, when the train passes through the electrical segmentation (at this time, electrical phase separation), the main circuit breaker needs to be disconnected to perform power-off phase separation. Due to the randomness of the decoupling of the traction power supply system, if the train cannot judge or receive the decoupling information in time and disconnect the main circuit breaker, a phase-breaking accident will occur, causing arc discharge of the contact network, ablation of the contact network and the pantograph, and even causing serious consequences such as line breakage, endangering the traction power supply system and driving safety. At present, the research and application of bilateral power supply technology is still in its initial stage, and there is no mature solution to deal with the above problems. Summary of the invention

When the traction power supply system is switched from a bilateral power supply mode to a unilateral power supply mode, the third circuit breaker and the fourth circuit breaker are disconnected, and the electrical segmentation is converted to electrical phase division.

[0068] Specifically, the traction power supply system control unit can monitor the power supply mode of the traction power supply system. When the traction power supply system is decoupled from the bilateral power supply mode to the unilateral power supply mode, the third circuit breaker and the fourth circuit breaker are disconnected, the electrical segmentation is converted to electrical phase separation, the electrical phase separation contact network is not energized, the first power supply arm and the second power supply arm are separated, and the first ATP transponder and the second ATP transponder remain in working state. The traction power supply system control unit can be the control unit of the traction power supply system.

[0069] Step 102: The traction power supply system control unit transmits the power phase separation information to the train. When the train reaches the position of the first train automatic protection system transponder, it receives the over-phase separation information sent by the first train automatic protection system transponder and disconnects the main circuit breaker. When the train reaches the position of the second train automatic protection system transponder, it receives the over-phase separation information sent by the second train automatic protection system transponder and closes the main circuit breaker. The train completes the power outage of the over-phase separation.

[0070] Specifically, the electric phase information may indicate that the electric segment is converted into an electric phase. The main circuit breaker may be a main circuit breaker of a train.

[0071] In this embodiment, the vehicle-ground coordinated phase-separation method may further include:

[0072] Step 103: When the power supply mode of the traction power supply system is the bilateral power supply mode, the first circuit breaker, the second circuit breaker, the third circuit breaker and the fourth circuit breaker are closed, and the signals of the first train automatic protection system transponder and the second train automatic protection system transponder are shielded when the train passes through the electrical section, and the train completes the energized passage through the electrical section.

[0073] In this embodiment, after the third circuit breaker and the fourth circuit breaker are disconnected in step 101, the following steps may also be included:

[0074] The traction power supply system control unit controls the phase-opening indicator light and the power-off over-phase closing indicator light to be always on. If the train detects that the power-off over-phase opening indicator light is always on or receives the over-phase information sent by the first train automatic protection system transponder, the main circuit breaker is disconnected. If the train detects that the power-off over-phase closing indicator light is always on or receives the over-phase information sent by the second train automatic protection system transponder, the main circuit breaker is closed, and the train completes the power-off over-phase. The vehicle-ground coordinated over-phase method may also include: if the power-off over-phase opening indicator light and the power-off over-phase closing indicator light are always off and the over-phase information sent by the first train automatic protection system transponder and the second train automatic protection system transponder is not received, the train completes the energized passage through the electrical section.

[0075] like Fig. 9 As shown, in order to realize the safe and reliable passage of the train through the electrical segmentation / electrical phase separation in the dual / single-side power supply mode conversion state, prevent the occurrence of phase separation accidents, and improve the reliability of train operation, the fifth embodiment of the present invention provides a vehicle-ground coordinated phase separation method, which can be implemented by applying the vehicle-ground coordinated phase separation device described in the second embodiment, and the method includes:

[0076] Step 201: When the traction power supply system is switched from a bilateral power supply mode to a unilateral power supply mode, the third circuit breaker and the fourth circuit breaker are disconnected, and the electrical segmentation is converted to electrical phase division.

[0077] Step 202: The traction power supply system control unit controls the operation of the first automatic train protection system transponder and the second automatic train protection system transponder. When the train reaches the position of the first automatic train protection system transponder, it receives the over-phase information sent by the first automatic train protection system transponder and disconnects the main circuit breaker. When the train reaches the position of the second automatic train protection system transponder, it receives the over-phase information sent by the second automatic train protection system transponder and closes the main circuit breaker. The train completes the power-off of the over-phase.

[0078] In this embodiment, the vehicle-ground coordinated phase-separation method may further include:

[0079] Step 203: When the power supply mode of the traction power supply system is the bilateral power supply mode, the first circuit breaker, the second circuit breaker, the third circuit breaker and the fourth circuit breaker are closed, the traction power supply system control unit controls the first train automatic protection system transponder and the second train automatic protection system transponder to not work, and the train completes the energized passage through the electrical section.

[0080] like Fig.10 As shown, in order to realize the safe and reliable passage of the train through the electrical segmentation / electrical phase separation in the dual / single-side power supply mode conversion state, prevent the occurrence of phase separation accidents, and improve the reliability of train operation, the fifth embodiment of the present invention provides a vehicle-ground coordinated phase separation method, which can be implemented by applying the vehicle-ground coordinated phase separation device described in the third embodiment, and the method includes:

[0081] Step 301: monitor the power supply mode of the traction power supply system. When the traction power supply system is switched from a bilateral power supply mode to a unilateral power supply mode, the third circuit breaker and the fourth circuit breaker are disconnected, and the electrical segmentation is converted to electrical phase division.

[0082] Step 302: The traction power supply system control unit controls the phase-off indicator light and the power-off excessive phase-closing indicator light to be normally on. The train disconnects the main circuit breaker after detecting that the power-off excessive phase-off indicator light is normally on. The train closes the main circuit breaker after detecting that the power-off excessive phase-closing indicator light is normally on. The train completes the power-off excessive phase.

[0083] In this embodiment, the vehicle-ground coordinated phase-separation method may further include:

[0084] Step 303: When the power supply mode of the traction power supply system is the bilateral power supply mode, the first circuit breaker, the second circuit breaker, the third circuit breaker and the fourth circuit breaker are closed, and the traction power supply system control unit controls the power-off excessive phase opening indicator light and the power-off excessive phase closing indicator light to be normally off, and the train completes the energized passage through the electrical section.

[0085] The train can use an on-board image recognition method to identify the status of the power-off excessive phase opening indicator light and the power-off excessive phase closing indicator light. In order to improve safety, the driver can also manually determine the status of the power-off excessive phase opening indicator light and the power-off excessive phase closing indicator light, and the two methods are mutually backup.
