It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other at will.

[0019] With the deepening application and promotion of power collection system, traditional concentrators, collectors and special variable collection terminals and other devices have been widely used in power systems. However, with the rapid development of distributed energy such as photovoltaic and wind energy, more and more new products in the subdivided market have emerged, among which the distributed power access unit is particularly prominent. Such products not only can realize the effective access and management of distributed energy, but also can improve the flexibility and reliability of the whole power system. However, with the increase of products and the lack of unified standards for corresponding test methods and test systems, the existing test system usually needs to access the entity system of distributed power for testing and needs to be manually set and switched, resulting in complex test process and complex test system equipment.

[0020] Based on this, the example embodiment of the present application provides a distributed power access unit data acquisition function test system, which includes a host computer system, a simulated distributed power tool, a test platform and a concentrator. The simulated distributed power tool can simulate multiple types of virtual units without accessing the entity distributed power device, and the test system is simplified. At the same time, the host computer system can automatically switch the test data and virtual units remotely without manual setting and switching, simplifying the test process and improving the reliability of the test.

[0021] The example embodiment of the present application provides a distributed power access unit data acquisition function test system, as shown in Figure 1 The test system includes a host computer system, a simulated distributed power tool, a test platform and a concentrator. The host computer system is built-in test software for configuring test data and generating corresponding test instructions, running the test software and sending the test instructions to the simulated distributed power tool. The host computer system can realize data interaction with the simulated distributed power tool through the communication module to configure the test data or read the data read by the tested device. The host computer system can realize data interaction with the simulated distributed power tool through the concentrator and the test platform to configure the test data or read the data read by the tested device. The simulated distributed power tool is in communication connection with the host computer system, including at least one virtual unit, a processor and a human-computer interface, and the virtual unit and the human-computer interface are in communication connection with the processor respectively. The test platform is used for carrying the tested device and is in communication connection with the simulated distributed power tool. The concentrator is in communication connection with the host computer system and the test platform and is used for collecting the data of the simulated distributed power tool read by the tested device and transmitting the collected read data to the host computer system. The simulated distributed power tool of the test system can simulate multiple types of virtual units without accessing the entity distributed power device, and the test system is simplified. At the same time, the host computer system can automatically switch the test data and virtual units remotely without manual setting and switching, simplifying the test process and improving the reliability of the test.

[0022] The virtual unit can be a virtual inverter, a virtual charging pile or a virtual energy storage unit. In an embodiment, the simulation distributed power supply tooling includes three virtual units, i.e., a virtual inverter, a virtual charging pile and a virtual energy storage unit. The virtual inverter, the virtual charging pile and the virtual energy storage unit are respectively connected to the processor of the simulation distributed power supply tooling. The processor is exemplarily a SCCTM Concentrator Master Module SCC8130L-V01A. The host computer system realizes switching between different virtual units by issuing a 698 instruction. Meanwhile, the host computer system realizes switching of serial communication rate, protocol type, soft control data and acquisition data of different virtual units and displays the switching through a human-machine interface. The virtual inverter adopts a Modbus protocol as the protocol type and the soft control data includes five types of active power control, reactive power control, power factor control, active power percentage control and reactive power percentage control. The virtual charging pile adopts a 698 protocol as the protocol type and the soft control data includes four types of charging start, charging stop, active power control and active power percentage control. The virtual energy storage unit adopts a Modbus protocol as the protocol type and the soft control data includes four types of charging and discharging mode switching, active power control, active power percentage control and SOC target control.

[0023] The test data includes soft control data and acquisition data. Preferably, the soft control data can be configured and read through the host computer system, configured and read through the human-machine interface and configured and read through the test platform. The acquisition data can be configured and read through the host computer system, configured and read through the human-machine interface and read through the test platform. The host computer system includes a 4G module to realize configuration of the test data and reading of the reading data of the device under test. The test platform realizes communication with the simulation distributed power supply tooling through RS-485 or RJ45.

[0024] In an example embodiment, the working principle of the test system of the application is explained by taking a virtual inverter as an example. The soft control data of the virtual inverter includes five types of active power control, reactive power control, power factor control, active power percentage control, and reactive power percentage control; the collected data includes four types of voltage, current, active power, and reactive power. The soft control data can be configured through the host computer system or through the human-machine interface, and the collected data can be configured through the host computer system; for example, the host computer system sends 698 instructions through a 4G module to configure the soft control data and the collected data of the virtual unit of the simulated distributed power tool; after the test data configuration is completed, the test data can be displayed on the display screen of the human-machine interface, the test device obtains the soft control data and the collected data through the RS-485 or RJ45 port, and transmits the data read by the test device to the concentrator; the concentrator collects the data read by the test device, and transmits the collected read data to the host computer system, and the host computer system displays the data read by the test device on the display window, and the operator can compare the read data of the test device displayed on the host computer and the test data displayed on the human-machine interface of the simulated distributed power tool to determine whether the read data of the test device is correct. The stored data is in the form of power failure reservation, and after the test data of the virtual inverter is tested, the host computer system can switch the virtual unit of the simulated distributed power tool to other virtual units that have not been tested by sending 698 instructions, and test according to the above test steps until all virtual units are tested.
