The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
The following describes a method, an apparatus, a system, and a terminal device for testing an energy storage system according to an embodiment of the present invention with reference to the accompanying drawings.
Fig. 1 is a schematic flow chart of a method for testing an energy storage system according to an embodiment of the present invention. The method for testing the energy storage system can be applied to various existing terminal devices, such as computers and industrial personal computers, and can be particularly applied to an upper computer (the upper computer is test software running in the terminal devices) in the terminal devices. As shown in fig. 1, the method for testing the energy storage system includes the following steps:
and S101, issuing the target power to an energy storage system and recording issuing time.
Specifically, before starting the test, a test system as shown in fig. 2 needs to be built, and the terminal device configures communication modes and parameters corresponding to the energy storage system and the measuring device. Specifically, the terminal device selects the communication protocol type of the energy storage system, such as Modbus TCP/IP, Modbus RTU, and the like, so that normal communication can be performed between the terminal device and the energy storage system. The terminal device selects the type of the measuring device, such as 3390 power analyzer, electric meter, etc., so that the terminal device can collect the measurement data of the measuring device. The target power is the power that the energy storage system is expected to output. The terminal device issues the target power to the energy storage system, and records the time of issuing the target power, that is, the issuing time, where the target power may be pre-stored in the terminal device or imported before the test starts, and may be a single target power value or multiple target power values issued periodically, and multiple target power values may form a target power curve. The plurality of target power values issued periodically, that is, the target power issued to the energy storage system each time, may be different.
And S102, obtaining feedback power fed back by the energy storage system, and recording feedback time.
Specifically, in step S101, after the terminal device issues the target power to the energy storage system, the energy storage system receives the target power and performs power feedback according to the target power, where the feedback power is the feedback power, and the terminal device obtains the feedback power fed back by the energy storage system and records the time for the energy storage system to feed back the feedback power, that is, the feedback time. When the target power is a single target power value, the corresponding feedback power is also a single feedback power value. When the target power is a plurality of target power values, the corresponding feedback power is also a plurality of feedback power values, and the plurality of feedback power values may form a feedback power curve.
And S103, acquiring the actual execution power of the energy storage system acquired and output by the measuring equipment, and recording the output time.
Specifically, in step S101, after the terminal device issues the target power to the energy storage system, the energy storage system receives the target power and outputs power according to the target power, where the actually output power is the actually executed power. And the measuring equipment acquires the actual execution power output by the energy storage system and outputs the actual execution power. The terminal device obtains the actual execution power output by the measuring device, and records the time when the measuring device outputs the actual execution power, namely the output time. When the target power is a single target power value, the corresponding actual execution power is also a single actual execution power value. When the target power is a plurality of target power values, the corresponding actual execution power is also a plurality of actual execution power values, and the plurality of actual execution power values may form an actual execution power curve.
And S104, determining whether the response time of the energy storage system meets the test standard or not according to the issuing time, the feedback time and the output time.
Specifically, the terminal device determines whether the response time of the energy storage system meets the test standard according to the issuing time, the feedback time and the output time acquired in steps S101, S102 and S103. As a feasible implementation manner, the terminal device calculates a difference between the feedback time and the delivery time to obtain a first time difference; calculating a difference value between the output time and the issuing time to obtain a second time difference; and comparing the first time difference and the second time difference with corresponding time difference threshold values respectively, and if the first time difference is smaller than a preset first time difference threshold value and the second time difference is smaller than a preset second time difference threshold value, determining that the response time of the energy storage system meets the test standard.
And S105, determining whether the output power of the energy storage system meets the test standard or not according to the target power, the feedback power and the actual execution power.
Specifically, the terminal device determines whether the output power of the energy storage system meets the test standard according to the target power, the feedback power and the actual execution power obtained in steps S101, S102 and S103. As a possible implementation manner, the terminal device calculates a difference between the feedback power and the target power to obtain a first power difference; calculating a difference value between the actual execution power and the target power to obtain a second power difference value; and comparing the first power difference and the second power difference with corresponding power difference thresholds respectively, and if the first power difference is smaller than a preset first power difference threshold and the second power difference is smaller than a preset second power difference threshold, determining that the output power of the energy storage system meets the test standard.
After the test is completed, the terminal device can also output a standard conformance test report, such as a test report in a CSV format, to a local folder according to the test data and the test result, so that a user can conveniently check the test result.
