IEEE 1547.1 Test Tools

Enabling an Efficient and Automated Testing of IEEE 1547.1 Interoperability

IEEE 1547.1-2020-based certification has been mandated in many states, including California and Hawaii, with many others requiring the same standards to be met. QualityLogic’s IEEE 1547.1 Test Tool has helped many OEMs and NRTLs in their execution of the IEEE 1547.1/UL 1741SB certification testing since 2021. The test tool has also been an essential component of many OEMs’ ability to pass official NRTL-based certification.

NEW! Fully Automated Data Analysis!

Our new IEEE 1547.1 Analysis feature will provide participating customers access to fully automated data analysis – built on the expertise we have gained from delivering this type of analysis to OEMs before/during the actual NRTL certification.

Introducing QualityLogic’s IEEE 1547.1 Test Tools

With the approval and adoption of IEEE 1547.1-2020 and the September 2021 update to UL 1741 Version 3, the inverter industry now has an opportunity to standardize its communications interactions with grid operators. QualityLogic leveraged its experience and know-how with IEEE 2030.5 to develop the IEEE 1547.1 Interoperability Test Tool for the interoperability testing required in UL 1741 SB. We also added support for SunSpec Modbus and DNP3 Interoperability testing requirements in UL 1741 SB and went further to support Type tests using all three protocols.

Unlike protocol testing, UL 1741 SB is a functional test specification (based on IEEE 1547.1-2020) that requires an actual inverter product (unit under test) to be set up in an inverter testing lab with a grid simulator, DC power supply, and data capturing equipment. Using the popular SCPI interface, QualityLogic’s 1547.1 test tools have a complete equipment management module that automatically sets starts and manages the lab equipment settings and data capture for each Interoperability and Type test defined in UL 1741 SB. All of the equipment control is “out-of-the-box” for supported equipment: no scripting is required. By standardizing the management of inverter testing equipment, QualityLogic’s 1547.1 test tools provide a quantum leap in efficiency and quality of UL 1741 SB testing and certification.

The most important value of the toolset is the automation of the IEEE 1547.1/UL 1741 testing process. UL 1741 SB testing can take 8 – 12 weeks to complete all the required setup, testing, and analysis. By automating much of the process using QualityLogic’s 1547.1 test tools, significant time savings can be realized, and your product can get to market faster.

IEEE 1547.1 Training Workshop

QualityLogic offers a training workshop for companies interested in learning about the IEEE 1547.1 / UL 1741 SB-based standards and certification testing.

Since 2021, QualityLogic has helped OEMs and NRTLs by providing an in-depth technical workshop that provides fundamental knowledge of IEEE 1547, UL 1741 SB, and testing of each of the IEEE 1547 grid support tests by using a live inverter lab for the workshop attendees. QualityLogic’s training workshop provides attendees with a deeper understanding of the standards and teaches the technical skills needed to conduct the testing defined in UL 1741 SB.

IEEE 1547.1 Interoperability and Type Tests

IEEE 1547.1 test standard defines Interoperability Tests that require using a DER communication protocol to configure and manage the target DER device. Using the supported protocol, a set of tests are defined that validate the DER device for interoperability.

  • DER Communication Protocol – IEEE 2030.5, IEEE 1815 (DNP3), or SunSpec Modbus are the supported protocols for DER devices to be supported. One of these protocols must be supported by the target DER device under test as a local communication interface.
  • Nameplate Data Tests – Verifies that a set of nameplate data can be read from the target DER using one of the three supported protocols.
  • Configuration Information Tests – Verifies that a set of DER settings can be read and adjusted using one of the three supported protocols. The DER settings will be independently compared to the reported values from the connected test equipment.
  • Monitoring Information Tests – Verifies that a set of DER-monitored data can be reported by the DER using one of the three supported protocols. The monitored data will be independently compared to the reported values from the connected test equipment.
  • Management Information and Type Tests – Verifies that a set of grid support functions can be communicated through the use of the supported DER communication protocol and that the desired effect be implemented by the target DER at the power level. These tests leverage the 1547.1 Type tests that are defined for the required grid support functions.

Key Features of the New QualityLogic IEEE 1547.1 Test Tools

NEW! Automatic Data Analysis: Measurements of the DER’s 1547-based behaviors will be automatically analyzed against the IEEE 1547 required accuracies so that the user can quickly determine whether their DER device is in compliance or not – saving hours of time over users manually analyzing the collected data. 

Test Equipment Automation: Automation is included right out of the box and does not require the user to write a single line of automation script. Each 1547.1 FTS test case remotely controls and monitors the list of required Test Equipment.

Automation Support: 1547.1 FTS test tool has REST API functions that enable customers to use automation scripts to control and execute 1547.1 tests.

Customizable 1547.1 Test Values: Enables the user to modify the test values that are used during testing, such as the values that are used during each grid code test.

New IEEE 1547.1 FTS and Type Tests: Supports the IEEE 1547.1 Interoperability Tests Section 6 and Type Tests Section 5. Includes support for Nameplate Data test, Configuration Information Test, Monitoring Information Test, and Management Information Test sections.

DER Protocols: Supports the 2030.5 and SunSpec Modbus communications required by each of the IEEE 1547.1 Interoperability tests with the target DER. DNP3 is supported based on the customer’s interests.

End-to-End Testing: 1547.1 FTS performs end-to-end testing where the DER is configured and managed through the selected DER Protocol while the power-based testing and verification are performed in an automated fashion.

Customizable 1547.1 Test Values – Enables the user to modify the test values that are used during testing, such as the values that are used during each grid code test.
