FRT & FFCI STUDY

Objective

Fault Ride-Through (FRT) and Fault Current Contribution Impact (FCCI) studies are critical for ensuring the stability and reliability of renewable energy systems during fault conditions. Our expertise in these studies helps to ensure compliance with Australian grid codes, such as AEMO Generator Performance Standards (GPS), while enhancing system resilience. We focus on ensuring that renewable energy systems, including inverters, wind turbines, and Battery Energy Storage Systems (BESS), can maintain grid stability during faults and disturbances.

Methodology

• Fault Ride-Through Analysis: We evaluate the capability of generating units, including inverters, wind turbines, and BESS, to remain connected to the grid during voltage dips and faults, ensuring seamless operation during disturbances.
• Fault Current Contribution Assessment: We determine the fault current contributions from generators and inverter-based resources under different fault scenarios to verify their impact on system protection schemes.
• Grid Code Compliance: We ensure compliance with Australian standards and regulations by modeling and analyzing system performance during faults.

Examples

We conducted FRT FCCI studies to evaluate the inverter performance during voltage sags caused by nearby transmission line faults. The analysis ensured the inverters met AEMO, Western Power, or Horizon Power GPS requirements, maintaining grid stability while staying online during transient disturbances.
We assessed the fault current contribution of BESS integrated into a hybrid renewable projects. The studies provided insights into the system’s impact on protection devices and led to optimized and adaptive relay settings for seamless fault isolation.
For wind power systems, we analyzed the ability of turbines to ride through faults and determined their fault current contributions.

By delivering precise FRT and FCCI studies aligned with Australian grid codes, we help renewable energy systems achieve seamless fault performance, minimize disruptions, and maintain compliance with operational and regulatory standards.
