One or more embodiments of the present application disclose an energy storage project simulation test system. Referring to fig. 1, the energy storage item simulation test system includes:
a first system controller, an analog platform, and a second system controller.
The first system controller may be an energy management system (english: energy Management System, abbreviated as EMS) controller.
The simulation platform comprises virtual equipment corresponding to the hardware equipment to be tested in the energy storage project, namely, a plurality of modules are arranged in the simulation platform, each module realizes the function of the hardware equipment in a code form, and thus each module is one virtual equipment or each module is one type of virtual equipment.
By way of example, the simulation platform may take the form of hardware of a host computer, and the application is not limited to a particular hardware form of the simulation platform.
The second system controller is respectively connected with the first system controller and the simulation platform; the second system controller is used for sending virtual equipment configuration information of the target virtual equipment corresponding to the hardware equipment to be tested to the simulation platform and sending virtual equipment parameter information to the first system controller; the simulation platform is used for configuring information of the target virtual equipment according to the virtual equipment configuration information, and the first system controller is used for determining interface information under the condition of communicating with the target virtual equipment according to the virtual equipment parameter information; the second system controller is also used for sending project test information to a simulation system formed by the first system controller and the target virtual equipment so as to carry out project test.
The second system controller may be an upper computer, a server or a computer, which is not limited in the specific hardware form of the second system controller, and the schematic diagram of the present application is illustrated by taking the computer as an example.
For example: the hardware equipment to be tested needed in the energy storage project to be developed at present is a battery management system (English: battery Management System, abbreviated as BMS), then the second system controller determines that the virtual equipment corresponding to the battery management system is a target virtual equipment, the hardware equipment to be tested needed in the energy storage project to be developed at present is an air conditioner, then the second system controller determines that the virtual equipment corresponding to the air conditioner is a target virtual equipment, and of course, when the simulation platform simulates, the simulation platform can simulate not only 1 hardware equipment at a time but also a plurality of identical hardware equipment at the same time, and at the moment, a plurality of target virtual equipment exist, for example: if 5 BMS are simulated at the same time, the virtual devices corresponding to the 5 BMS are target virtual devices, and the simulation platform may also simulate a plurality of different hardware devices, for example: 6 BMSs, 6 air conditioners and 1 fire control controller can be simulated at the same time, and at the moment, virtual equipment corresponding to the 6 BMSs, the 6 air conditioners and the 1 fire control controller is determined to be target virtual equipment.
The simulation platform can support simulation and simulate a plurality of inverters (English: power Conversion System, abbreviated as PCS), a plurality of BMSs, a plurality of air conditioners, a plurality of fire control controllers and a plurality of electric meters, and can greatly facilitate development and debugging work of energy storage projects.
The analog platform and the second system controller can be connected through an interface control.
The first system controller is connected with the simulation platform and is used for performing read-write control on the target virtual equipment.
The functions of the target virtual device simulated by the simulation platform and the hardware device to be tested are the same when the target virtual device is running, so that the first system controller can also perform read-write control required by test with the target virtual device simulated by the simulation platform, for example: the real-time data of the running time can be read from the simulation platform when the test information of the running project of the target virtual equipment in the simulation platform is tested, and the functional data which is required to be simulated by the target virtual equipment in the simulation platform can be written into the simulation platform.
In this embodiment, a simulation platform may be used to simulate virtual devices of different hardware devices to be tested in the energy storage project to be developed, so that when the energy storage project is developed, it is not necessary to prepare a large number of physical hardware devices to be tested, thereby reducing the development cost of the energy storage project and shortening the development period.
In one embodiment, when the target virtual device is a PCS and/or a BMS, because the PCS and the BMS perform information transmission through a network port when performing information interaction with a first system controller (e.g., EMS), the energy storage project simulation test system in the present application further includes: and a switch.
The first network port of the first system controller is connected with a second network port corresponding to the target virtual equipment through the switch;
the virtual equipment configuration information comprises connection configuration information of the second network port, and the virtual equipment parameter information comprises connection configuration information of the second network port; the simulation platform is used for configuring the second network port according to the connection configuration information of the second network port, and the first system controller is used for controlling the first network port to establish a communication link with the second network port according to the connection configuration information of the second network port.
Multiple network ports can be arranged in the hardware of the simulation platform to meet the requirements of the physical interfaces of the simulated virtual equipment.
For example: the hardware of the simulation platform can support 2 network ports, as shown in fig. 2, there are 6 BMS and 6 PCS in the current energy storage project, and the network ports corresponding to the target virtual devices in the simulation platform can be connected with the network ports corresponding to the first system controller through the switch to form a communication link.
In one embodiment, since the number of PCS and BMS simulated by the simulation platform is plural, virtual IP needs to be used for distinguishing, at this time, the connection configuration information of the second network port is a virtual IP address and a port number corresponding to the target virtual device, and the first system controller is configured to control the first network port to establish a communication link with the second network port through the virtual IP address and the port number.
It should be noted that, the target virtual device simulated by the simulation platform and the first system controller may be in communication connection using the Modbus TCP protocol.
For example, the BMS device simulated by the simulation platform sets the ip address field to 192.168.1.199-204, the port number 10001-10006,Modbus Slave id to 1, and the first system controller may access the BMS1 through 192.168.1.199 10001 and perform normal data interaction; the PCS equipment simulated by the simulation platform sets the ip address field as 192.168.1.221-226, the port number as 10011-10016,Modbus Slave id as 1, and the first system controller can access the PCS1 through 192.168.1.221 10011 to perform normal data interaction.
For example, the second portal configuration information of the BMS1 simulated by the simulation platform is:
[bms#1]；
ETH0_IP=192.168.1.199；
LOCAL_PORT=10001。
in one embodiment, when the target virtual device is a virtual device corresponding to an air conditioner, a fire controller and an ammeter, because the air conditioner, the fire controller and the ammeter perform information transmission through serial interfaces when performing information interaction with the first system controller, the first serial interface (english: cluster communication port, abbreviated as: COM) of the first system controller is also required to be connected with the second serial interface of the target virtual device.
The virtual equipment configuration information comprises connection configuration information of the second serial interface, and the virtual equipment parameter information comprises connection configuration information of the first serial interface; the first system controller is used for configuring the first serial interface according to the connection configuration information of the first serial interface, and the analog platform is used for configuring the second serial interface according to the connection configuration information of the second serial interface, so that the first serial interface and the second serial interface form a communication link capable of communicating.
Multiple serial interfaces may be provided in the hardware of the simulation platform to meet the physical interface requirements of the simulated virtual device.
For example, if the simulated virtual device includes 6 air conditioners, 1 fire control controller and 2 electric meters, as shown in fig. 2, the 6 air conditioners are connected with one RS485 bus RS485-1, the 1 fire control controller is connected with one RS485 bus RS485-2, and the 2 electric meters are respectively RS485-3 and RS485-4 through independent RS485 connection.
In one embodiment, the connection configuration information of the first serial interface includes: the interface identification of the second serial interface, the baud rate of the first serial interface, the parity bit of the first serial interface, the data bit of the first serial interface and the stop bit of the first serial interface;
the connection configuration information of the second serial interface includes: the interface identification of the first serial interface, the baud rate of the first serial interface, the parity bit of the first serial interface, the data bit of the first serial interface, and the stop bit of the first serial interface.
Continuing with the example of FIG. 2, where the target virtual device simulated by the simulation platform is 6 air conditioners, then the interface identifier of the first serial interface is set for air conditioners 1-6 as: COM1, the baud rate of the first serial interface is 9600, the parity bit of the first serial interface is n, the data bit of the first serial interface is 8, the stop bit of the first serial interface is 1, the corresponding Modbus Slave id is 1-6, and the first system controller can access 6 pieces of air-conditioning data through COM 1; the fire protection, electricity meter 1, electricity meter 2 are similar to the air conditioning arrangement and will not be described in detail here.
For example, the virtual device configuration information of COM1 is:
[com#1]；
COM_PORT=COM1；
COM_BAUD=9600；
COM_PARIYT=N；
COM_DATA_BITS=8；
COM_STOP_BITS=1。
in one embodiment, the second system controller is configured to send a point table of the target virtual device to the simulation platform; the simulation platform is used for configuring the target virtual equipment according to the point table.
Because the simulation platform can simulate a plurality of hardware devices, independent data partition processing needs to be performed on different hardware devices, in this embodiment, a point table (mb_mapping) of different data partitions may be set, then different storage areas are bound through the data partition mb_mapping mapping, and a start address and an end address of each storage area of the device, after the simulation platform receives the point table, the data storage areas of the virtual devices corresponding to the simulated hardware devices to be tested may be configured according to the point table.
In one embodiment, the second system controller is configured to send test data corresponding to the target virtual device to the simulation platform; the simulation platform is used for receiving the test data and running the target virtual equipment according to the test data; the first system controller is used for receiving real-time data after the target virtual equipment operates.
When the energy storage project is developed, after the simulation platform simulates virtual equipment of all hardware equipment required by the energy storage project, the whole project is built, at the moment, the second system controller can send test data to each target virtual equipment in the simulation platform, after the simulation platform receives the test data and operates, the first system controller can receive an operation result, whether the currently developed energy storage project meets requirements or not can be determined through the operation result, and if not, corresponding modification is carried out.
The testing herein may include: the modification of the operation data and the fault alarm data are input in an analog mode.
Taking BMS equipment as an example, the data such as total voltage and total current of real BMS hardware equipment are collected and changed in real time, but because the simulation platform in the application is simulated and is virtual equipment, the data on the simulation platform can be changed by means of operation of a second system controller, and therefore, during testing, project test information needs to be input into the virtual equipment through the second system controller, and then the virtual equipment can achieve the same operation purpose as the real hardware equipment after operating the project test information.
In one embodiment, when the target virtual device is a plurality of identical devices, the second system controller is configured to send a linkage instruction corresponding to the target virtual device to the simulation platform; the simulation platform is used for receiving the linkage instruction and simultaneously controlling the target virtual equipment to execute linkage operation according to the linkage instruction; the first system controller is used for receiving real-time data after the analog platform executes the linkage instruction.
After the simulation platform simulates the virtual devices of all hardware devices required by the energy storage project, the multiple virtual devices can be simultaneously controlled to simultaneously execute a certain operation through the linkage instruction, for example: and synchronously controlling each cluster of the BMS to perform high-voltage power-on/power-off operation.
The following describes in detail the flow of the operation of the simulation platform in the present application:
1. and (5) reading a configuration file.
As shown in fig. 3, the simulation platform software reads the virtual device configuration information config. Ini, extracts relevant configuration information therefrom, and initializes the thread parameters of the target virtual device corresponding to the hardware device to be simulated (BMS, PCS, air conditioner, fire controller, electricity meter).
By way of example, the configuration file config. Ini is:
[bms#1]；
ETH0_IP=192.168.1.199；
LOCAL_PORT=10001；
[com#1]；
COM_PORT=COM1；
COM_BAUD=9600；
COM_PARIYT=N；
COM_DATA_BITS=8；
COM_STOP_BITS=1。
2. simulation platform hardware initialization.
And initializing hardware (network port and COM port) corresponding to each target virtual device in the simulation platform by the simulation platform according to the corresponding parameters in the virtual device configuration information.
3. The simulation platform simulates system information initialization.
When the target virtual equipment is BMS and PCS, because the BMS and PCS to be simulated by the simulation platform are large in quantity and use the same network port, virtual ip technology is needed to be adopted to set virtual ips of the virtual BMS equipment and the virtual PCS equipment, and the first system controller can access different ip addresses through the switch to achieve the effect of the virtual equipment.
4. The data storage area is initialized.
And initializing the data storage area in the simulation platform according to the areas of different virtual devices, and performing independent data partition processing on the different virtual devices.
The method comprises the steps of setting an ID of a virtual device, setting an mbmapping of different data partitions, binding different storage areas through mbmapping mapping of the data partitions, associating the mbmapping with threads of the current simulation device, setting a starting address and an ending address of the modbus storage area, indicating supported instructions, and directly accessing the required data storage area through thread parameters after initialization is completed.
5. And starting each target virtual device thread, wherein each target virtual device is provided with an independent server, waits for the first system controller to access data, and automatically links according to the real-time data.
In FIG. 3, analog PCS thread [1] corresponds to PCS data store [1], analog PCS thread [2] corresponds to PCS data store [2], and so on; the simulated BMS thread [1] corresponds to the BMS data storage area [1], the simulated BMS thread [2] corresponds to the BMS data storage area [2], and so on; the simulated other device thread [1] corresponds to the other data store [1], the simulated other device thread [2] corresponds to the other data store [2], and so on.
The scheme when the simulation platform simulates the BMS device is described in detail below using the BMS as an example, as shown in fig. 4.
BMS equipment has total accuse and cluster accuse architecture design, and the information is summarized to total accuse and cluster accuse detailed information is related to, including monomer temperature voltage, and the data volume is huge, and especially on large-scale energy storage project, the cluster number is up to tens, and corresponding data volume that needs the simulation is huge. Currently, the modbus access points of a single BMS device are limited to 65536, and cannot meet the requirement of total control and cluster control on huge data access. In addition, the modbus point positions of different manufacturers are different in address, and the simulation requirement cannot be met through simple data segmentation, for example, the BMS data total voltage modbus address of the A manufacturer is 0x101 (hexadecimal), the BMS data total voltage address of the B manufacturer is 0x2055 (hexadecimal), the address difference is large, and the simulation requirement cannot be met through simple data segmentation.
The second system controller inputs virtual device configuration information required for simulating the BMS device to the simulation platform through the control of the simulation platform.
According to the method and the device, the data access is distinguished in a mode that different BMS total controls and cluster controls are defined for the modbus slave id, and the problem of data point location coverage is solved. For example: in fig. 4, the slave id of the master control of the analog BMS is 1, the slave id of the analog BCU cluster control is 2-33 (the maximum 32 clusters are supported for the analog, the large energy storage requirement is met), wherein the slave id of the analog BCU cluster control 1 is 2, the slave id of the analog BCU cluster control 2 is 3, and so on. Each slave id maps an independent data point table mb_mapping, has 65536 independent points, and when receiving a slave id request, the BMS simulation device 1 actively switches and accesses the received slave id mb_mapping, processes and responds data with the received slave id, thereby solving the problem that BMS protocols of different manufacturers can simulate access.
And in this application, different virtual BMS1-BMS6 equipment distinguishes through virtual ip and different port numbers, and different independent threads simulate, and every virtual BMS equipment all possesses same simulation method, reaches the effect of simulating a plurality of BMS in simulation platform.
The user can access the modified or imported analog data through the background control, and the first system controller can compare and analyze the read data and the pre-modified or imported data to debug the BMS protocol analysis work. Particularly, fault alarm data are subjected to analog input, such as emergency stop triggering, fire control, BMS hardware faults, 1-3 level alarm items and the like, so that a security policy mechanism of an energy storage item is conveniently debugged.
Meanwhile, the virtual equipment BMS has a data linkage function, and when receiving a one-key grid-connected/off-grid instruction issued by the EMS, the virtual equipment BMS synchronously controls each cluster of the BMS to perform high-voltage power-on/power-off operation, and simulates the effect of a real control instruction. When the current point position data is detected, the charging and discharging states of the BMS are automatically switched, and when the fault point position data is detected, signals such as charge inhibition and discharge inhibition are automatically switched, so that the energy storage project debugging control logic and strategy are greatly facilitated.
