Sophisticated web-based simulation tool offers streamlined analysis for harmonic mitigation
Harmonics is a complex subject, and professionals often find it daunting to start their journey due to a lack of effective tools for understanding. MyDrive® Harmonics addresses this challenge by setting a new benchmark in harmonic analysis and mitigation in HVAC drives. Its advanced simulation capabilities, combined with its focus on accuracy and user-centric design, will help engineers mitigate harmonic distortions in HVAC systems.
The software is a sophisticated web-based tool designed to streamline harmonic analysis for electrical systems. It helps determine potential harmonic issues when integrating drives into existing HVAC installations or designing new ones. By utilizing user-provided system data, including one-line diagrams and load profiles, the tool accurately simulates harmonic distortion levels—such as THDi, THVD, and TDD—at critical points, including the Point of Common Coupling (PCC). It evaluates compliance with regional standards like IEEE 519 and EN 61000-2-4, and offers a visual spectrum analysis to pinpoint potential problem areas.
Users are able to experiment with various Danfoss harmonic mitigation solutions, comparing their effectiveness and cost-efficiency. The tool generates detailed reports and equipment lists based on optimized simulations, facilitating a smooth implementation process. MyDrive® Harmonics is ideal for managing harmonic distortion in both new projects and system expansions, ensuring compliance and enhancing system performance.
Unlike traditional tools that rely on simplified calculations, it delivers precise predictions of harmonic distortion with an impressive accuracy of ±5%. This level of detail allows for thorough evaluation of mitigation strategies and confident compliance assessment.
The tool introduces several groundbreaking features:
-
True Simulation: Offers detailed, reliable results beyond basic Excel calculations.
-
Compliance Flexibility: Users can select compliance locations, such as primary or secondary utility transformer points, and choose from various international standards, including multiple revisions of IEEE-519.
-
Hybrid Mitigation Configurations: Supports customized solutions by allowing users to mix passive filters, active filters, and active front-end drives.
“MyDrive® Harmonics sets a new industry standard by providing a comprehensive, flexible approach to harmonic analysis, facilitating precise system design and optimization with unmatched performance and control,” said John Streicher, regional product manager at Danfoss Drives. “It empowers engineers to make informed decisions, ensuring safe, effective and cost-efficient solutions.”
