Detailed Description
The embodiments of the invention will be described in detail hereinafter with reference to the accompanying drawings, but the invention can be implemented in many different ways, which are defined and covered by the claims.
Example 1:
as shown in fig. 1, an energy storage power supply system for a monorail excursion train comprises an energy storage unit, a high-voltage box 2, a charging bow 3 and a maintenance charging port 4; the two groups of energy storage units are arranged in parallel on a bus 9 in the high-voltage box 2; the charging bow 3 is arranged on the bus 9 in parallel; the maintenance charging port 4 is provided with two ports, the two ports are connected in parallel on the bus 9, and the charging bow 3 and the maintenance charging port 4 are used for charging the energy storage unit. The charging bow 3 is connected to a bus 9 of the high-voltage box 2 through a charging bow control contactor 7. The maintenance charging port 4 is connected to a bus 9 of the high-voltage box 2 through a maintenance charging port control contactor 8.
The energy storage unit comprises two energy storage power supply energy storage boxes 1 which are connected in series, and the energy storage power supply energy storage boxes 1 are arranged on the roof of the carriage. The energy storage power supply energy storage box 1 is connected to a bus 9 of the high-voltage box 2 through an energy storage unit control contactor 5. A super capacitor is arranged in the energy storage power supply energy storage box 1, and green energy is stored in the energy storage power supply energy storage box 1.
And a maintenance grounding switch 6 is arranged on a circuit connecting the energy storage power supply energy storage box 1 and the bus 9 and is used for performing grounding protection on the energy storage power supply energy storage box 1. When a train enters a maintenance room for maintenance, a maintenance grounding switch in the high-voltage box is switched to a grounding position, so that the safety of maintainers can be protected, and meanwhile, the train is interlocked with a train power-on control logic, and the closing and the power-on are strictly forbidden during the maintenance.
The application of the energy storage power supply system on the train is as follows:
analysis from before train travel:
1. and giving a power-on signal to the energy storage system through a train driver. At this point the energy storage system begins communication detection. When the communication of all the components is detected to be normal, the two groups of energy storage units respectively start to collect and analyze the state information of the energy storage units, and synchronously report the state and the data to the train control system. The information includes the voltage, current, electric quantity and other parameter values of the energy storage unit, and also includes the relevant parameter values of the high-voltage box. Finally, the train control system determines the actuation of the control contactor of the energy storage unit by judging whether the parameter value is in a normal range, so that the safety of the energy storage system before the input is ensured. For example, faults such as overvoltage, undervoltage, overcurrent and low electric quantity can be judged in advance through the train control system to judge whether the energy storage system is in a normal state, and the conditions are self-checking of the energy storage system and checking of the train control system.
2. Because the utility model discloses a parallelly connected power supply of two sets of energy storage units, the high energy storage unit of voltage charges to the energy storage unit that voltage is low through the generating line of high-voltage box when can the unbalanced voltage, consequently when train control system is obtaining the voltage parameter of two sets of energy storage units, can be through the height and the difference of comparison calculated voltage to send energy storage unit contactor control command. The calculation logic of the command for controlling whether the contactor is closed or not by the train control system is as follows:
(a) if the difference value of the output voltages of the two groups of energy storage units is less than or equal to 10V (the specific value is mainly based on field debugging), the contactors of the two groups of energy storage units can start to pull in.
(b) If the difference value of the output voltages of the two groups of energy storage units is larger than 10V, the contactor of the energy storage unit with high voltage can be actuated first, and the contactor of the energy storage unit with low voltage is kept disconnected. And simultaneously, starting a vehicle load, and discharging through the vehicle load to consume the electric quantity of the high-voltage energy storage system at a reasonable speed. When the train control system detects that the difference value of the output voltages of the two groups of energy storage units is less than or equal to 10V, the train control system informs the contactor of the other group of energy storage units to pull in.
This is the parallel switching process of two groups of energy storage units.
Analyzing from the running process of the train:
1. the train control system monitors the state of the energy storage system in real time and displays the state to inform drivers, once a certain energy storage unit has a major fault, the train control system automatically cuts off the contactor of the energy storage unit, and the other energy storage unit continues to provide electric quantity to ensure the train to run. If the high-voltage box has faults, the train control system can also automatically cut off the two paths of energy storage unit contactors.
2. When the train is required to be charged when the train arrives at the station, the charging bow of the train is in contact with the charging rail in the station. The train control system reports parameters such as voltage and electric quantity of the energy storage system to charging equipment in the station through communication, the charging equipment analyzes the parameter values and sends a charging instruction to the train control system, and therefore the contactor is controlled to be closed, the charging bow and the charging equipment in the station charge the energy storage power supply, and meanwhile power is supplied to loads of a carriage.
Analyzing in the process of overhauling or charging the train in the warehouse:
1. when the charging gun is plugged in the train, the train control system reports the voltage, the electric quantity and other parameters of the energy storage system to the charging equipment in the maintenance warehouse through communication, and the charging equipment analyzes the parameter values and sends a chargeable instruction to the train control system, so that the contactor is controlled to be actuated to charge the energy storage power supply or provide the maintenance power supply for the charging equipment in the maintenance warehouse. And meanwhile, the energy storage power supply is interlocked with a control contactor of the charging bow, and only one charging mode is allowed to charge the energy storage power supply.
2. When the maintenance is carried out in the maintenance warehouse, the maintenance grounding switch of the high-voltage box can be manually operated, the energy storage unit cannot be interconnected with the high-voltage box bus at the moment, and the maintenance grounding switch is interlocked with the control of the charging bow contactor and the power-on control of the train, so that the safety of maintenance personnel is ensured.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
