[0032] Figure 1 It is a structural diagram of a multi-distributed power simulation device based on a concentrator according to a preferred embodiment of the present invention.

[0033] The present invention provides a distributed power simulation device. The device provided by the present invention is comprehensive and reliable, and can be applied in a test environment composed of a host computer system, a concentrator, and a simulated distributed power source, meeting the requirements of test environments such as electromagnetic compatibility, high and low temperatures, and quickly satisfying the detection of distributed power access unit devices.

[0034] The hardware of the distributed power simulation device provided by the present invention can select a concentrator, which has been maturely applied in the power system and has very good stability. The software needs to be modified to achieve the purpose of switching multiple different virtual units such as simulated charging piles, inverters, and energy storage units through the host computer system. At the same time, the communication content of different virtual units can be simulated in two ways: remote setting through the host computer system and direct setting through the human-machine interface. Then, the 4G module, RS-485 module, and control system of the device cooperate together to realize the setting and reading of the soft control parameters and data acquisition parameters of different virtual units (simulated charging piles, inverters, and energy storage units).

[0035] As Figure 1 shown, the present invention provides a multi-distributed power simulation device based on a concentrator. The device includes: a host computer system 101 and virtual units; the virtual units include: a virtual inverter 101-1, a virtual charging pile 101-2, and a virtual energy storage unit 101-3;

[0036] The host computer system switches the simulation test of the virtual unit through 698 instructions and sends a message in the corresponding format to the virtual unit;

[0037] The host computer system communicates with the virtual unit through corresponding messages, sets data for the virtual unit, and verifies the virtual unit by reading the feedback data of the virtual unit.

[0038] The host computer system stores the set data.

[0039] The main functions of the distributed power supply tooling of the present invention are as follows:

[0040] The present invention can set soft control data and acquisition data in a set manner, arbitrarily change the virtual unit data, and greatly reduce the test waiting time and improve the detection efficiency when testing the data reading ability of the device under test.

[0041] The present invention realizes the switching function of the virtual unit: The virtual unit is divided into three types: virtual inverter, virtual charging pile, and virtual energy storage unit. The host computer system switches the serial port rate, protocol type, and soft control data content of the distributed power supply tooling by issuing a 698 instruction, thereby realizing the switching of the virtual unit. The serial port rate of the virtual inverter is 9600,n,8,1, the protocol type is Modbus protocol, and the soft control data includes five types: active power control, reactive power control, power factor control, active power percentage control, and reactive power percentage control; the serial port rate of the virtual charging pile is 9600,e,8,1, the protocol type is 698 protocol, and the soft control data includes four types: charging start, charging stop, active power control, and active power percentage control.

[0042] The present invention supports storing data: The data set by the host computer through 698 can still retain the set data after power failure and restart.

[0043] Preferably, when the host computer switches the virtual inverter, the serial port rate is 9600,n,8,1, the protocol type is Modbus protocol, and the soft control data in the data parameters includes active power control, reactive power control, power factor control, active power percentage control, and reactive power percentage control.

[0044] Preferably, when the host computer switches the virtual charging pile, the serial port rate is 9600,e,8,1, the protocol type is 698 protocol, and the soft control data in the data parameters includes charging start, charging stop, active power control, and active power percentage control.

[0045] Preferably, the host computer sets the data parameters of the virtual unit through remote setting or human-machine interface method.

[0046] The present invention realizes the functions of setting and reading soft-control data and acquisition data: Taking a virtual inverter as an example, the soft-control data includes five types: active power control, reactive power control, power factor control, active power percentage control, and reactive power percentage control, and the acquisition data includes four types: voltage, current, active power, and reactive power. The setting and reading of data include two methods: remote setting by the upper computer system and direct setting through the human-machine interface. The upper computer can issue 698 instructions through 4G to realize the setting and reading of the soft-control data and acquisition data of the virtual unit of the distributed power supply tooling, and the human-machine interface directly sets the data acquisition parameters through the liquid crystal interface. The device under test obtains the soft-control data and acquisition data through the 485 port to verify various functions of the device under test.

[0047] The control system of the present invention includes the control software of the device and the related hardware for running the control software. The control software is divided into two parts: the main control part running on the embedded industrial computer and the slave control part running on the embedded single-chip microcomputer. The two work in coordination through communication. The main control part is responsible for the operation of the entire device, responsible for the communication processing of the device, and conducts data interaction with the test system and the device under test; the slave control part realizes the intuitive display of analog data through data interaction with the main control module.

[0048] The present invention completes the conversion of 2-way TTL to RS485 through the RS485 module to complete the 485 communication function of the analog meter product;

[0049] The analog distributed power supply tooling data provided by the present invention can be remotely and automatically set. Each time the device conducts a test, a set of data is randomly generated, and is remotely issued through a specific message format using 4G. After the setting is completed, reading and verification are carried out to achieve the effect of simulating the real environment.

[0050] The present invention can simulate different types of distributed power supplies. It includes the functions and data of simulating inverters, charging piles, and energy storage.

[0051] The test device provided by the present invention is stable and reliable, and the designed service life of the hardware can reach more than 15 years. The device provided by the present invention can remotely and automatically issue data, avoiding the problems of manual setting and switching, reducing the test operation steps, and ensuring the accuracy of the data. The device provided by the present invention can simulate multiple distributed power supplies, streamline the test equipment (reduce various physical devices required for the test setup environment), and improve the safety, reliability, and automation level of the test work.
