The main objective of the project is to achieve a cost-effective device which is capable of being used in equipment testing environments. The tests for which the TAPAS technology is to be used are aimed at testing the immunity of the equipment under test during power supply transients. The supply voltage levels are low voltage, both direct current (DC) and alternating current (AC). It is also proposed that single-phase and three-phase power supply systems can be tested. Some voltage levels that would be used during testing involve a dangerous situation. Therefore, another important specification is that the tests are performed without the possibility of electrical contact between the test operator and the equipment under test. This means that the operator must always maintain a safe distance from the test area.
The equipment configuration can be defined as the set of three blocks. First is the operator block. This block consists of a PC that, through a web browser, will be the client of the service provided by the Smart Lab Tool for Power Transient Analysis. The user must be able to configure parameters such as type of voltage applied (DC/AC), amplitude, frequency, type of transient. The user will also have access to test images. This will allow a visual inspection of the performance of the equipment under test during the course of the test. The second block consists of the test service server. The server must be able to provide a web page to accept the configuration parameters, acquire images from a webcam connected to it and program the TAPAS to perform the tests according to the parameters received from the user. Finally, the third block is made up of the TAPAS which is configured and executes the tests providing the voltage values to the equipment under test. The attached figure represents both the three zones and the equipment to be located in each of these zones. The system operator's zone does not have to be physically in the same place as the other two zones, as the system operator's zone can be physically separated from the other two zones via a local network connection (wired or wireless), or via the Internet. On the other hand, the Smart Lab Tool for Power Transient Analysis area and the area of the equipment under test should be in the same room.
The implementation of the complete system consists of two elements: a Raspberry Pi (can be any type of PC) as server and TAPAS. The DC power supply will be connected to both the Raspberry Pi and the TAPAS. The Raspberry Pi will be connected to a router via Ethernet or WiFi to provide the web service. The Raspberry Pi is physically connected to the TAPAS due to its compatibility. By using Python as programming language, user data is collected. Furthermore, the Rapsberry Pi programs the TAPAS for providing the output voltage. The power supply of the equipment under test is connected directly to the TAPAS.
The proposed development could be implemented by several people with different roles: software-oriented and hardware-oriented. But because of the simplicity of an initial proof of concept, it will be developed by a person with multidisciplinary skills. In the case of extending the proposed functionalities, it would be necessary to form a team of several people with different roles. A needed role should be oriented to Full Stack. Other needed role should be oriented to development of power electronics applications.
The implementation of this proposal requires only one unit of the TAPAS.
this idea will get one TAPAS dev kit
