Description

Technical Field

[0001] The invention relates to a power control method for a dual-source trolleybus, in particular to a power distribution control method for a dual-source trolleybus in the same network segment. Background Art

[0002] With the advancement of science and technology, dual-source trolleybuses are gradually replacing traditional trolleybuses and becoming the main type of urban trolleybuses. Like traditional trolleybuses, dual-source trolleybuses use the wire network as a power source. On sections with wired networks, dual-source trolleybuses also use collector poles to connect to the wire network for travel. The difference between dual-source trolleybuses and traditional trolleybuses is that dual-source trolleybuses are also equipped with power batteries. When the collector pole of the dual-source trolleybus is connected to the wire network for travel, the power battery can be charged and stored with the power of the wire network. On sections with wireless networks, dual-source trolleybuses can use power batteries to travel without the wire network.

[0003] See also Figure 1 , Figure 1 The schematic diagram of multiple dual-source trolleybuses running based on the line network is shown. In normal operation, there will be many dual-source trolleybuses 2 in operation under the entire line network 1. The dual-source trolleybuses 2 are electrically connected to the line network 1 through the collector poles 21 configured on their roofs. The dual-source trolleybuses 2 can import electric energy from the line network through the collector poles 21 for the dual-source trolleybuses 2 to travel and charge the power batteries. The line network 1 is usually not continuous, but is composed of a series of line network segments 11 connected and combined. An insulating connector 12 is provided between adjacent line network segments 11. The function of the insulating connector 12 is to connect adjacent line network segments 11 in an insulating manner.

[0004] There are usually multiple dual-source trolleybuses 2 in operation under each network segment 11. The electric energy imported from the network segment 11 by these dual-source trolleybuses 2 is used for both normal driving and charging the power battery. The power load borne by a network segment 11 is very large. However, the load power of each network segment 11 is limited to a certain extent. If the load power of the network segment 11 is too large, the cable facilities in the network segment 11 will be damaged, resulting in serious consequences. Therefore, in order to avoid such a situation, each network segment 11 will be equipped with an overload protection switch. When the network segment 11 is overloaded, the overload protection switch will trip, which will have a serious impact on the vehicles running under the network segment 11.

[0005] To sum up, the current problem to be solved is: how to ensure that the line network segment does not have a load power overload, and at the same time ensure that all dual-source trolleybuses based on the line network segment can run normally and that the power battery has sufficient power value for the dual-source trolleybus to run on the wireless network section.

[0006] A Chinese patent (CN110979031A) discloses an intelligent energy management method for dual-source trackless vehicles, which combines road information and vehicle operation load information and effectively controls DC / DC to better control the planning of SOC operation range, so as to effectively improve the power efficiency of dual-source trackless vehicles and ensure the safety of the line network. However, the patent does not solve the problem of power distribution between multiple dual-source trolleybuses 2 in the same line network segment.

[0007] The SOC (State of Charge) is used to reflect the remaining capacity of the battery. Its value is defined as the ratio of the remaining capacity to the battery capacity, usually expressed as a percentage. Its value range is 0~100%. When SOC=0%, it means that the battery is fully discharged, and when SOC=100%, it means that the battery is fully charged. Summary of the invention

[0008] The object of the present invention is to provide a power distribution control method for dual-source trolleybuses in the same network segment. The power distribution control method can enable a dual-source trolleybus with a low power battery value to obtain sufficient charging power first, so as to balance the power values ​​of all dual-source trolleybuses in the network segment, under the premise of ensuring that the network segment is not overloaded.

[0009] In order to achieve the above technical objectives, the present invention adopts the following technical solutions:

[0010] A power distribution control method for dual-source trolleybuses in the same network segment, wherein a carrier communication module is arranged on the dual-source trolleybus, and a communication end of the carrier communication module is connected to a power line in a collector pole;

[0011] The power distribution control method comprises the following steps:

[0012] Step 1: All dual-source trolleybuses in the same line network segment establish communication links with each other through the carrier communication module;

[0013] Step 2, all dual-source trolleybuses in the line network segment periodically communicate vehicle status data information with each other;

[0014] Step 3: Each dual-source trolleybus in the line network segment periodically performs a power dispatching process, and the power dispatching process includes:

[0015] Step 3.1, determine whether the total power request of the entire network segment exceeds the allocatable power of the network segment, if so, execute step 3.2, otherwise, allocate power on demand to all dual-source trolleybuses in the network segment to meet the total power request of the entire network segment, and then end the current power dispatch process;

[0016] Step 3.2, according to the power value of the power battery in the dual-source trolleybus, in the order of power value from low to high, all the dual-source trolleybuses in the line network segment are divided into n power levels, in which the power value of the dual-source trolleybus in the preceding power level is less than the power value of the dual-source trolleybus in the succeeding power level; n is a natural number greater than 1;

[0017] Step 3.3, the power allocation process is optimized for the dual-source trolleybuses in the 1st to nth power levels in turn, and the allocatable power of the line network segment is preferentially allocated to the dual-source trolleybuses in the power levels with the highest ranking.

[0018] Furthermore, the process of optimizing power allocation in step 3.3 includes:

[0019] Determine whether the total power request of the current power level exceeds the allocatable power of the line network segment. If so, then: allocate all the allocatable power of the line network segment to the dual-source trolleybuses in the current power level, and for each dual-source trolleybus in the current power level, allocate the same proportion of load power in the allocatable power of the line network segment to the dual-source trolleybus according to the proportion of the power request quota of the dual-source trolleybus in the total power request of the current power level, and then end the current power dispatch process;

[0020] Otherwise: the allocatable power of the line network segment is preferentially allocated to the dual-source trolleybuses in the current power level to preferentially meet the total power request of the current power level.

[0021] Furthermore, the step 2 also includes: the cycle time of the vehicle status data information of the dual-source trolleybuses in the line network segment is 1 second.

[0022] Furthermore, the step 3 also includes: the power scheduling process is executed for a period of 5 seconds.

[0023] Furthermore, the value of n is 3, so that the dual-source trolleybuses in the line network segment are divided into the first power level, the second power level and the third power level.

[0024] Furthermore, the power value of the power battery in the dual-source trolleybus adopts the SOC value, the SOC value of the dual-source trolleybus in the first power level is less than 25%, the SOC value of the dual-source trolleybus in the second power level is between 25% and 85%, and the SOC value of the dual-source trolleybus in the third power level is greater than 85%.

[0025] Furthermore, the power value of the power battery in the dual-source trolleybus adopts the SOC value.

[0026] By adopting the power allocation and control method of the present invention, when the maximum allowable load power of a network segment cannot meet the power demand of all dual-source trolleybuses in the network segment, all dual-source trolleybuses in the network segment are divided into power levels according to the power values ​​of the power batteries in the dual-source trolleybuses, and then the allocable power of the network segment is preferentially allocated to the power levels of the dual-source trolleybuses with small power values, so that the dual-source trolleybuses with small power battery power values ​​can preferentially obtain sufficient power to ensure their effective charging.

[0027] Compared with the prior art, the power allocation control method of the present invention has the beneficial effect that, under the premise of ensuring that the line network segment is not overloaded and tripped to cut off power, the limited allocatable power of the line network segment is preferentially allocated to the dual-source trolleybus with a low power battery value, so that it can preferentially obtain sufficient charging power to balance the power values ​​of all dual-source trolleybuses in the line network segment, thereby preventing the dual-source trolleybus from breaking down on the road section of the wireless network due to the low power battery value, thereby ensuring that all dual-source trolleybuses in the line network segment can operate normally.

[0032] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0033] See also Figure 2 and Figure 3 This embodiment provides a power distribution and control method for dual-source trolleybuses in the same network segment. The power distribution and control method can ensure that the dual-source trolleybus 2 with a low power battery value obtains sufficient charging power first, while ensuring that the line network segment 11 is not overloaded.

[0034] See also Figure 2 In this embodiment, each dual-source trolleybus 2 is provided with a carrier communication module 22 , and a communication end of the carrier communication module 22 is connected to the power line in the collector pole 21 .

[0035] See also Figure 3 The power allocation control method of this embodiment includes the following steps 1 to 3.

[0036] Step 1: All dual-source trolleybuses 2 in the same network segment 11 establish communication links with each other through the carrier communication module 22.

[0037] Specifically, when a dual-source trolleybus 2 enters the line network segment 11, the dual-source trolleybus 2 establishes an electric connection with the line network segment 11 through the collector pole 21, and at the same time, the dual-source trolleybus 2 also establishes communication with other dual-source trolleybuses 2 in the line network segment 11 through the carrier communication module 22. Compared with re-establishing a dedicated communication line, the carrier communication module 22 is used on the basis of the existing line network 1 to realize the communication between each dual-source trolleybus 2, which has a simple structure, is easy to construct, has a low construction cost, and has good reliability.

[0038] Step 2: All dual-source trolleybuses 2 in the network segment 11 periodically communicate with each other about vehicle status data through mutual communication, and the cycle of information communication is 1 second.

[0039] Specifically, a vehicle status record table of the same network segment is set in the main control module of the dual-source trolleybus 2, which records the vehicle status data information such as the identification number, network status, SOC value, power request quota, actual power quota and vehicle active number of all dual-source trolleybuses 2 (including this vehicle) in the same line network segment 11. When the dual-source trolleybus 2 enters the line network segment 11 and establishes communication with other dual-source trolleybuses 2 in the line network segment 11, the vehicle status record table of the same network segment is initialized first, including clearing the data records of other dual-source trolleybuses 2 in the vehicle status record table of the same network segment, and setting the actual power quota of this vehicle to zero, and then it starts to periodically communicate the data information in the vehicle status record table of the same network segment with other dual-source trolleybuses 2 in the same line network segment 11, including exchanging the data information of SOC value and power request quota.

[0040] When initializing data information of the vehicle status record table of the same network segment, the data records of other dual-source trolleybuses 2 in the vehicle status record table of the same network segment are cleared, the purpose of which is to clear the vehicle information of the previous line network segment recorded before the vehicle enters the line network segment 11, so as to ensure that the vehicle information of the line network segment 11 is synchronized again; the actual power quota of the vehicle is set to zero, the purpose of which is to prevent the vehicle from requesting power from the line network segment after entering the line network segment 11 but before completing the power scheduling process, thereby ensuring that the new dual-source trolleybus will not increase the power load of a line network segment when entering the line network segment, thereby avoiding overloading of the line network segment.

[0041] The power request quota refers to the expected value of the power supply obtained from the line network, which is calculated in real time by the dual-source trolleybus operating on the line network based on its own SOC value, power demand of driving conditions and other data.

[0042] Step 3: Each dual-source trolleybus 2 in the line network segment 11 periodically performs a power dispatching process. The power dispatching process is specifically performed by a main control module of the dual-source trolleybus 2, and the execution cycle is 5 seconds.

[0043] The power scheduling process includes the following S1 to S5.

[0044] S1, determine whether the total power request of the entire network segment 11 exceeds the allocatable power of the network segment 11. If so, continue to execute S2, otherwise, allocate power on demand to all dual-source trolleybuses 2 in the network segment 11 to meet the total power request of the entire network segment 11, and then end the current power scheduling process.

[0045] The total power request amount of the entire network segment 11 refers to the sum of the power request quotas of all dual-source trolleybuses 2 in the entire network segment 11 .

[0046] The allocatable power of the network segment 11 in S1 is the maximum allowable load power of the network segment 11 .

[0047] The total power request amount satisfying the entire network segment 11 specifically means that all dual-source trolleybuses 2 in the network segment 11 can set the collector pole import power according to their own power request quota.

[0048] S2, according to the SOC values ​​of the power batteries in the dual-source trolleybuses 2, in the order of the SOC values ​​from low to high, all the dual-source trolleybuses 2 in the network segment 11 are divided into three power levels, and the three power levels are low power level, medium power level and high power level in the order of the SOC values ​​of the dual-source trolleybuses 2 from low to high, wherein the SOC values ​​of the dual-source trolleybuses 2 in the low power level are all less than 25%, the SOC values ​​of the dual-source trolleybuses 2 in the medium power level are all between 25% and 85%, and the SOC values ​​of the dual-source trolleybuses 2 in the high power level are all greater than 85%.

[0049] S3, determine whether the total power request of the low power level exceeds the allocable power of the line network segment 11, if so, then: allocating all the allocable power of the line network segment 11 to the dual-source trolleybus 2 in the low power level, and for each dual-source trolleybus 2 in the low power level, according to the proportion of the power request quota of the dual-source trolleybus 2 in the total power request of the low power level, allocate the same proportion of load power in the allocable power of the line network segment 11 to the dual-source trolleybus 2, at this time, the allocable power of the line network segment 11 has been allocable to the dual-source trolleybus 2 in the low power level, and there is no more allocable power for allocating power to the dual-source trolleybus 2 in the medium power level and the high power level, so the power scheduling process can be ended;

[0050] Otherwise: the allocatable power of the network segment 11 is preferentially allocated to the dual-source trolleybus 2 in the low power level to meet the total power request of the low power level, and the remaining power allocated to the low power level is used to allocate power to the dual-source trolleybus 2 in the medium power level and the high power level.

[0051] The total power request amount at the low power level refers to the sum of the power request quotas of all dual-source trolleybuses 2 at the low power level.

[0052] The allocatable power of the network segment 11 in S3 is the maximum allowable load power of the network segment 11 .

[0053] The total power request amount that satisfies the low power level specifically means that all the dual-source trolleybuses 2 in the low power level set the collector pole import power according to their own power request quotas.

[0054] The low power level allocation surplus power specifically refers to the load power remaining after deducting the total power request of the low power level from the allocatable power of the network segment 11 .

[0055] S4, determine whether the total power request of the medium power level exceeds the allocatable power of the network segment 11, if so, then: all the allocatable power of the network segment 11 is allocatable to the dual-source trolleybus 2 in the medium power level, and for each dual-source trolleybus 2 in the medium power level, according to the proportion of the power request quota of the dual-source trolleybus 2 in the total power request of the medium power level, an equal proportion of the load power in the allocatable power of the network segment 11 is allocatable to the dual-source trolleybus 2. At this time, the allocatable power of the network segment 11 has been allocatable to the dual-source trolleybus 2 in the medium power level, and there is no more allocatable power for allocating power to the dual-source trolleybus 2 in the high power level, so the power scheduling process can be ended.

[0056] Otherwise: the allocatable power of the network segment 11 is preferentially allocated to the dual-source trolleybus 2 in the medium power level to meet the total power request of the medium power level, and the remaining power allocated in the medium power level is used to allocate power to the dual-source trolleybus 2 in the high power level.

[0057] The total power request amount of the medium power level refers to the sum of the power request quotas of all dual-source trolleybuses 2 in the medium power level.

[0058] In S4, the allocatable power of the network segment 11 is the remaining power allocated to the low power level.

[0059] The total power request amount that meets the medium power level specifically means that all dual-source trolleybuses 2 in the medium power level set the collector pole import power according to their own power request quotas.

[0060] The medium power level allocation surplus power specifically refers to the load power remaining after deducting the total power request of the medium power level from the allocatable power of the network segment 11 .

[0061] S5, judging whether the total power request of the high power level exceeds the allocable power of the line network segment 11, if so, then: allocating all the allocable power of the line network segment 11 to the dual-source trolleybus 2 in the high power level, and for each dual-source trolleybus 2 in the high power level, according to the proportion of the power request quota of the dual-source trolleybus 2 in the total power request of the high power level, allocating the same proportion of the load power in the allocable power of the line network segment 11 to the dual-source trolleybus 2, and then ending the current power dispatching process;

[0062] Otherwise: satisfy the total power request for the high power level.

[0063] The total power request amount at the high power level refers to the sum of the power request quotas of all dual-source trolleybuses 2 at the high power level.

[0064] The allocatable power of the network segment 11 in S5 is the remaining power allocated to the medium power level.

[0065] The total power request amount that satisfies the high power level specifically means that all the dual-source trolleybuses 2 in the high power level set the collector pole import power according to their own power request quotas.

[0066] The power scheduling process from S1 to S5 can be summarized as the following steps 3.1 to 3.3.

[0067] Step 3.1, determine whether the total power request of the entire network segment 11 exceeds the allocatable power of the network segment 11. If so, continue to execute step 3.2. Otherwise, allocate power on demand to all dual-source trolleybuses 2 in the network segment 11 to meet the total power request of the entire network segment 11, and then end the current power scheduling process.

[0068] The total power request amount of the entire network segment 11 refers to the sum of the power request quotas of all dual-source trolleybuses 2 in the entire network segment 11 .

[0069] The allocatable power of the network segment 11 in step 3.1 is the maximum allowable load power of the network segment 11.

[0070] The total power request amount satisfying the entire network segment 11 specifically means that all dual-source trolleybuses 2 in the network segment 11 can set the collector pole import power according to their own power request quota.

[0071] Step 3.2, according to the SOC value of the power battery in the dual-source trolleybus 2, in the order of SOC value from low to high, all the dual-source trolleybuses 2 in the network segment 11 are divided into n power levels, among which the SOC value of the dual-source trolleybus 2 in the preceding power level is less than the SOC value of the dual-source trolleybus 2 in the succeeding power level; and n is a natural number greater than 1.

[0072] In this embodiment, the value of n is 3, so that the dual-source trolleybus 2 in the line network segment 11 is divided into the first power level, the second power level and the third power level, wherein the first power level corresponds to the low power level, the second power level corresponds to the medium power level, and the third power level corresponds to the high power level. In other embodiments, there is no restriction on the specific value of n, which can be determined according to needs and circumstances.

[0073] Step 3.3, optimize the power allocation process for the dual-source trolleybuses 2 in the 1st to nth power levels in turn until the power scheduling process is completed, so that the allocatable power of the network segment 11 is preferentially allocated to the dual-source trolleybuses 2 in the top power levels.

[0074] The process of optimizing power allocation includes:

[0075] Determine whether the total power request of the current power level exceeds the allocable power of the line network segment 11. If so, then: allocate all the allocable power of the line network segment 11 to the dual-source trolleybus 2 in the current power level, and for each dual-source trolleybus 2 in the current power level, allocate the same proportion of load power in the allocable power of the line network segment 11 to the dual-source trolleybus 2 according to the proportion of the power request quota of the dual-source trolleybus 2 in the total power request of the current power level. At this time, the allocable power of the line network segment 11 has been allocable to the dual-source trolleybus 2 in the current power level, and there is no more allocable power for allocating power to the dual-source trolleybus 2 in the subsequent power level, so the power scheduling process can be ended;

[0076] Otherwise: the allocatable power of the network segment 11 is preferentially allocated to the dual-source trolleybus 2 in the current power level to preferentially meet the total power request of the current power level. If there are subsequent power levels that have not been allocated power, the remaining power allocated to the current power level will be used to allocate power to the dual-source trolleybus 2 in the subsequent power levels.

[0077] The total power request amount of the power level refers to the sum of the power request quotas of all dual-source trolleybuses 2 in the power level.

[0078] In step 3.3, if the current power level is the first power level, the allocatable power of the network segment 11 is the maximum allowable load power of the network segment 11, otherwise the allocatable power of the network segment 11 is the remaining power allocated at the previous power level.

[0079] The total power request amount that satisfies the current power level specifically means that all dual-source trolleybuses 2 in the current power level set the collector pole import power according to their own power request quotas.

[0080] The current power level allocation surplus power specifically refers to the load power remaining after deducting the total power request amount of the current power level from the allocatable power of the network segment 11 .

[0081] In the process of executing step 3, all required data information is provided by the vehicle status record table of the same network segment of the dual-source trolleybus 2 itself or calculated based on the data in the table.

[0082] In this embodiment, the power dispatching process is performed by each dual-source trolleybus 2 itself, rather than by a central dispatching platform. Since the cycle time of executing the power dispatching process is short, it can basically ensure that all dual-source trolleybuses 2 execute the power dispatching process synchronously. If there is a lack of synchronization, the execution cycle can be appropriately reduced to solve the problem of asynchrony. This non-central dispatching method has low cost and is relatively easy to implement.

[0083] By adopting the power allocation and control method of the present embodiment, when the maximum allowable load power of the network segment 11 cannot meet the power demand of all the dual-source trolleybuses 2 in the network segment 11, all the dual-source trolleybuses 2 in the network segment 11 are divided into power levels according to the power values ​​of the power batteries in the dual-source trolleybuses 2, and then the allocatable power of the network segment 11 is preferentially allocated to the power levels of the dual-source trolleybuses 2 with small power values, so that the dual-source trolleybuses 2 with small power battery power values ​​can preferentially obtain sufficient power to ensure their effective charging.

[0084] In general, the power allocation and control method of the present embodiment has the advantages that, within the same line network segment 11, on the premise that the line network segment 11 is not overloaded and tripped to cut off power, the limited allocable power of the line network segment 11 is preferentially allocated to the dual-source trolleybus 2 with a low power battery value, so that it can preferentially obtain sufficient charging power to balance the power values ​​of all dual-source trolleybuses 2 in the line network segment 11, thereby preventing the dual-source trolleybus 2 from breaking down on the wireless network section due to the low power battery value, thereby ensuring that all dual-source trolleybuses 2 in the line network segment 11 can operate normally.

[0085] In this embodiment, the power value of the power battery is quantified in the form of SOC value, and in other embodiments, other quantification forms may also be used, and the present invention is not limited to this.

[0086] The SOC value of the dual-source trolleybus 2 mentioned in this article refers to the SOC value of the power battery of the dual-source trolleybus 2 .

[0087] The carrier communication module is a device belonging to the prior art, and its function is to achieve communication through power transmission lines.
